10 beat ventricular tachycardia (1.8%), and nonsustained ventricular tachycardia (7.9%), however, were higher in the nonrandomized compared with the ITT population. Published by Wolters Kluwer Health, Inc. Other demographic variables were well balanced among the treatment groups. At baseline, there was a high rate of atrial tachycardia in the ITT population (41.8%). A total of 1178 (81%) patients completed the studies (ranging from 77% to 85% across the treatment groups). Fatal arrhythmias are a common cause of death in chronic obstructive pulmonary disease (COPD). It is unclear whether these comorbidities are due to the disease itself27,28, its associated risk factors8,26,31, or its treatment24. COPD can damage lung tissue. Arrhythmias that occur in the atria (the top chambers of the heart) are supraventricular (above the ventricles) in origin. 16. Please enable scripts and reload this page. The rates of the other more serious arrhythmias did not increase with LABA treatment and were similar to placebo. Baseline Clinical Characteristics and Medical Histories*, Proportion of Patients With Holter Arrhythmia Events at Baseline*, Cumulative Proportion of COPD Patients With Treatment-Emergent (Not Present at Baseline) Holter Arrhythmia Events Over 12 Weeks of Treatment, Proportion of Patients at Weeks 0 (Post-First Dose), 6, and 12 With Treatment-Emergent (Not Present at Baseline) Holter Arrhythmia Events, Cumulative Proportion of COPD Patients With Holter Arrhythmia Events Present Over 12 Weeks of Treatment, Proportion of Patients at Weeks 0 (Post-First Dose), 6, and 12 With Holter Arrhythmia Events Present at Each Visit Including Baseline, Patients With Treatment-Emergent Cardiovascular Adverse Events. Changes (and 95% CIs) from baseline in mean heart rate (over 24 hours) and maximum mean hourly heart rate (highest mean hourly heart rate in the 24-hour period) as measured by 24-hour Holter monitoring were presented.

Arrhythmias in patients with chronic obstructive pulmonary disease. The rates of serious cardiovascular events (0.7%-1.4%) were similar in the LABA and placebo groups, but the proportion of patients who discontinued due to cardiovascular adverse events was slightly higher in those with LABA treatment (3.8%) compared to those with placebo (1.7%; p = 0.101). Sin DD, Man SF. Eligible patients were entered into a 2-week single-blind placebo run-in period. The percentage of patients with cardiovascular adverse events was 11.2%. Please try after some time. The proportion of patients with treatment-emergent atrial tachycardia ranged from 27% to 32% and was non-significantly higher, by ∼2%-5% (p = 0.70), in the LABA groups compared with the placebo group. Whether these results imply that arrhythmia risk is related more to underlying comorbidities than to airway function compromise is not known. 27. Hanrahan, Grogan, Baumgartner, Wilson, and Mr. Cheng were full-time employees of Sepracor Inc. when the study was conducted. Dr. Baumgartner is currently at Inotek Pharmaceuticals Corp., Beverly, MA. She says she woke this morning feeling fine but experienced increasing dyspnea over the past six hours that’s unrelieved with use of her metered-dose inhalers (MDIs). AFib can cause blood to pool in the atria, which can lead to blood clots, stroke, and heart failure. to maintaining your privacy and will not share your personal information without Patients with MAT frequently have significant comorbidities, especially chronic obstructive pulmonary disease (COPD) and respiratory failure, and are often treated in ICUs. Patients were randomized to LABA treatment or placebo for 12 weeks: a) nebulized arformoterol 15 μg BID, b) 25 μg BID, or c) 50 μg QD; d) salmeterol metered dose inhaler 42 μg BID; or e) placebo. Few studies have had an adequate number of patients and sufficient duration of monitoring to characterize the occurrence of transient and infrequent arrhythmias such as atrial fibrillation and ventricular tachycardia. Recent estimates are that more than 12 million adults are currently diagnosed with COPD, and that the actual prevalence may be more than double that number23. Comparisons between all intent-to-treat (ITT) patients and nonrandomized patients at baseline were performed using the Fisher exact test. At baseline, there was a low frequency of occurrence of atrial fibrillation/flutter (0.1%), nonsustained ventricular tachycardia (3.1%), and >10 beat ventricular tachycardia (0.3%). Hanrahan, John P. MD, MPH; Grogan, Donna R. MD; Baumgartner, Rudolf A. MD; Wilson, Amy PhD; Cheng, Hailong MS; Zimetbaum, Peter J. MD; Morganroth, Joel MD. Anesthesia is associated with cardiac arrhythmias for several reasons, including : Abbreviations: bpm = beats per minute, CI = confidence interval, COPD = chronic obstructive pulmonary disease, FEV1 = forced expiratory volume in 1 second, FVC = forced vital capacity, ITT = intent-to-treat, LABA = long-acting beta2-agonist, MedDRA = Medical Dictionary for Regulatory Activities. Major exclusion criteria were the use of non-protocol-specified beta-agonists; life-threatening/unstable respiratory status within 30 days before screening; asthma or any chronic respiratory disease other than COPD; lung resection of more than 1 full lobe; and/or continuous supplemental oxygen (unless the patient resided at elevation ≥4000 feet). The primary cause of COPD is tobacco smoke (including second­hand or passive exposure). Atrial fibrillation (AF) is one of the most common arrhythmias and causes substantial morbidity and mortality. Chronic obstructive pulmonary disease (COPD) is a significant and increasing cause of death in the United States20,21. World Medical Association Declaration of Helsinki. Smoking is the most common cause and the greatest risk factor for COPD, resulting in as many as 90 percent of deaths. Treatment with inhaled LABA therapy in these trials did not increase the occurrence of serious arrhythmias, and did not result in a mean increase in heart rate as assessed by 24-hour Holter monitoring. Some error has occurred while processing your request. A total of 1829 patients met eligibility at the screening visit and received single-blind placebo; 364 patients were not randomized, 329 of whom had a baseline Holter assessment (nonrandomized patients). In terms of diagnosed cases, this makes COPD the second most common lung disease in the UK, after asthma. Chronic obstructive pulmonary disease (COPD) is one of the most important comorbidities of CVD, which causes serious consequences in patients with ischemic heart disease, stroke, arrhythmia, and heart failure. The 24-hour Holter monitoring was performed pretreatment and at Weeks 0 (first day of dosing), 6, and 12. When asked specifically, she says her dyspnea gets worse with exertion, but she feels “almost normal” when sitting down. The Authors. The institutional review boards at each study site approved each protocol, and written informed consent was obtained from all participants. All patients had moderate to severe COPD, and those with stable cardiac or other comorbidities were not excluded from the study cohort. [email protected]. This website uses cookies. Bestall JC, Paul EA, Garrod R, Garnham R, Jones PW, Wedzicha JA. 29. 26. An estimated 1.2 million people are living with diagnosed COPD – considerably more than the 835,000 estimated by the Department of Health in 2011. Most of the time, these Arrhythmias can be non-threatening, but there are instances where they can cause a few fatal conditions. Baseline heart rate was similar across groups (81.1-82.8 beats per minute [bpm]). You may be trying to access this site from a secured browser on the server.

The 2 trials were identically designed Phase III multicenter randomized trials. A complete description of the methodology has been reported previously2,14. A high proportion of patients had runs of atrial tachycardia at baseline, while few had more serious arrhythmias such as afibrillation/flutter, nonsustained ventricular tachycardia, and >10 beat ventricular tachycardia. Ferguson GT, Funck-Brentano C, Fischer T, Darken P, Reisner C. Cardiovascular safety of salmeterol in COPD. More patients who received LABAs also discontinued due to cardiovascular adverse events (3.8%) than those in the placebo group (1.9%). LABA administration did not increase mean heart rate. Efficacy of salmeterol xinafoate in the treatment of COPD. Holter monitoring was performed using a Burdick 6732 digital 3-channel Holter monitor at baseline (the first 24-hour period at the start of the 2-week single-blind placebo run-in), after the first dose at Week 0, and at Weeks 6 and 12. Overall, the proportion of LABA-treated patients with treatment-emergent (i.e., not present at baseline) nonsustained ventricular tachycardia was similar to placebo (p = 0.86), and atrial fibrillation/flutter and >10 beat ventricular tachycardia were rarely observed in all groups (Table 4). may email you for journal alerts and information, but is committed Patterns of comorbidities in newly diagnosed COPD and asthma in primary care. These arrhythmias are not responsible for dramatic events such as sudden cardiac death, but the most common arrhythmia, atrial fibrillation, is supraventricular and … There were 60 sites in the first study and 64 sites in the second study. Although asymptomatic in its early stages, COPD is characterized by a gradual and progressive loss of lung function, and is an independent risk factor for ventricular arrhythmia9 and cardiovascular morbidity and mortality16,28,29. These are the five most common symptoms of COPD: • Coughing. These medications were available to all patients, including those in the placebo group, as needed during the entire study period. Baseline was calculated from the 24-hour Holter records obtained at the start of the placebo run-in period 2 weeks before study drug administration. More serious arrhythmias were infrequent and did not increase with inhaled LABA therapy. 800-638-3030 (within USA), 301-223-2300 (international) For more information, please refer to our Privacy Policy. Usefulness of the Medical Research Council (MRC) dyspnoea scale as a measure of disability in patients with chronic obstructive pulmonary disease. This conclusion is supported by both the absence of a dose response with arformoterol and the lack of a statistically significant difference among the treatment groups. The effect of inhaled long-acting beta2-agonists (LABAs) on these outcomes was evaluated in patients with chronic obstructive pulmonary disease (COPD) in 2 double-blind randomized clinical trials.

Genomewide linkage analysis of quantitative spirometric phenotypes in severe early-onset chronic obstructive pulmonary disease. In this study, we attempted to non-invasively verify these hypotheses in hypoxaemic COPD patients that are not in respiratory failure by examining how PaO2, PaCO2, pH and HCO3 correlate with QTd in those patients. Nebulized arformoterol in patients with COPD: a 12-week, multicenter, randomized, double-blind, double-dummy, placebo- and active-controlled trial. Emerging risk factors for the development of AF include a variety of breathing disorders like COPD. During treatment, more patients in the placebo group used rescue albuterol (post-first dose, 35.8%; Week 6, 30.4%; Week 12, 28.0%) than patients in the active treatment groups throughout the monitoring period (range post-first dose, 20.5%-25.3%; range Week 6, 18.4%-20.3%; range Week 12, 17.1%-25.7%). Patients taking beta-blockers were also excluded. There is a high positive significant correlation between the age of patients, duration of COPD and Hb level and the occurrence of fatal arrhythmias where P values were 0.009, <0.0005 and <0.0005 respectively; the same as with QTd value where the P values were 0.015, 0.001 and 0.039. The fact that the majority of the arrhythmias were atrial fibrillation and flutter is consistent with the fact that this is the most common sustained arrhythmia encountered in clinical practice, 35 Sra J COPD patients are more likely to be diagnosed with CVD than the general population (odds ratio of 2.46). 24. 6. Lippincott Journals Subscribers, use your username or email along with your password to log in. Of the 1465 randomized patients, 1456 took at least 1 dose of double-blind study medication (ITT patients) and 1429 had a baseline Holter assessment. your express consent.

The QTc interval, autonomic neuropathy and mortality in hypoxaemic COPD. Lifetime environmental tobacco smoke exposure and the risk of chronic obstructive pulmonary disease. The occupational burden of chronic obstructive pulmonary disease. While increases in the number of patients with atrial fibrillation/flutter were observed with increasing doses of arformoterol, only a small proportion of patients was affected in each treatment group (0.3%-1.4%). We believe this was unlikely, as only a small percentage of patients in each treatment group discontinued due to cardiovascular adverse events, and the overall incidence of cardiovascular adverse events was similar across the treatments with no clear dose-response among arformoterol-treated patients. The highest proportion of withdrawals occurred in the placebo (21.8%) and arformoterol 25 μg BID groups (23.3%). They were double-blind, double-dummy, placebo- and active-controlled, parallel-group, 12-week multiple-dose clinical trials. Mahler DA, Donohue JF, Barbee RA, Goldman MD, Gross NJ, Wisniewski ME, Yancey SW, Zakes BA, Rickard KA, Anderson WH. This could have contributed to an underestimation of arrhythmia occurrence with longer duration of LABA treatment. Data is temporarily unavailable. Based on these interpretations, 2 board-certified internal medicine physicians at Sepracor Inc. retrospectively, but independently and blinded to treatment, categorized each overread Holter into 4 major arrhythmia categories: atrial tachycardia (≥4 beat run), atrial fibrillation/flutter, "nonsustained"; ventricular tachycardia (4-10 beat run), and "sustained"; ventricular tachycardia (>10 beat run). Conduction abnormalities were the most common ECG abnormality in COPD patients (28%) being significantly more prevalent than in patients without COPD (11%, p < 0.001). 17. COPD is associated with many comorbidities [ 2 , 3 ] ( figure 1 ) and can be one of multiple chronic or acute diseases and medical conditions present within one person [ 4 ]. 14. And if air leaks into the space between a lung and your chest wall, that lung can collapse like a deflated balloon. This review summarises the current knowledge on the different aspects of COPD exacerbations. AFib may happen in short bursts, last until treated, or might be a permanent condition. Fleg JL, Kennedy HL. From Sepracor Inc. (JPH, DRG, RAB, AW, HC), Marlborough, Massachusetts; Beth Israel Deaconess Medical Center (PJZ), Harvard Medical School, Boston, Massachusetts; University of Pennsylvania School of Medicine (JM) and eResearch Technology, Inc. (JM), Philadelphia, Pennsylvania. The number and percentage of patients who used rescue albuterol and supplemental ipratropium during the 24-hour Holter monitoring period were calculated for each assessment time. Nevertheless, use of inhaled short-acting beta2-agonists may have affected the occurrence of arrhythmias observed in all groups, especially the placebo group. 25 COPD patients were subjected for Standard 12-lead ECG for arrhythmia detection and the measurement of QT intervals, chest X-ray, two dimensional echocardiography and myocardial nuclear imaging to exclude IHD. The results are consistent with other studies in which the prevalence of arrhythmias following LABA treatment was determined by 24-hour ambulatory monitoring4,10. Glasser SP, Clark PI, Applebaum HJ. Management of COPD. 32. Yet these drugs, especially nonselective beta-agonists, directly increase the rate and vigor of cardiac contractions. The mean change from baseline over 24 hours in the active treatment groups was similar (difference of <2 bpm) to placebo over all post-baseline visits (post-first dose, Week 6, and Week 12), with little change observed over time (Table 2). Cardiac arrhythmias are quite common in people who are undergoing general anesthesia. By continuing you agree to the use of cookies. Yet even among all patients evaluated, the prevalence of atrial fibrillation was lower than that reported in a previous large longitudinal study (5.5%)15. Occurrence of frequent complex arrhythmias detected by ambulatory monitoring: findings in an apparently healthy asymptomatic elderly population. Chronic obstructive pulmonary disease as a risk factor for cardiovascular morbidity and mortality. Two studies were conducted between February 2002 and March 2004 under United States Food and Drug Administration regulations, which include principles established by Good Clinical Practice and the Declaration of Helsinki and its amendments32. In conclusion, the current study describes the occurrence frequency of 24-hour Holter-assessed arrhythmias in a large cohort of patients with moderate to severe COPD with no or stable cardiac comorbidities and the impact of LABA treatment on these arrhythmias. Recent guidelines6,18,24 recommend the use of long-acting bronchodilators, including long-acting beta2-agonists (LABAs), for maintenance treatment of moderate and more severe COPD. Consequently, a high mortality rate (ie, up to 45%) is associated with this arrhythmia, although it is not a direct consequence of the rhythm abnormality. Arrhythmias are common in most people who have undergone heart surgery or a coronary stent procedure or are genetically carrying a structural defect in the heart. 5. Our results rule out the electropathy hypothesis and underline autonomic neuropathy as the most possible mechanism of arrhythmias in hypoxaemic, non-respiratory failure, and COPD patients. Arrhythmic adverse events occurred in 4.4% of patients in the placebo group and in 3.1%-5.5% of patients in the LABA groups. Address reprint requests to: Amy Wilson, PhD, Sepracor Inc., 84 Waterford Drive, Marlborough, MA 01752. 30. Available at. Beta-adrenergic stimulation may increase heart rate and the potential for cardiac arrhythmias. They also observed that nonsustained ventricular tachycardia among these healthy elderly was associated with a higher relative risk of subsequent death (RR, 2.8; 95% CI, 1.2-6.4). We assessed the proportion of patients with each of 4 arrhythmias: atrial tachycardia, atrial fibrillation/flutter, and "nonsustained"; (4-10 beats) and "sustained"; (>10 beats) ventricular tachycardia. Eisner MD, Balmes J, Katz PP, Trupin L, Yelin EH, Blanc PD. It's caused by long-term exposure to irritating gases or particulate matter, most often from cigarette smoke. Ventricular tachycardia occurs when the ventricles start pounding away at up to 200 bpm—a disruption that can cause dizziness and breathlessness. Changes in the maximum hourly mean heart rate were also stable (difference of <2 bpm) across groups and visits (Table 2). Chronic obstructive pulmonary disease (COPD) is a progressive condition that makes it hard to breathe. Patients were given guidance on their use throughout the trial and were instructed to withhold them for 6 hours before clinic visits. This implies that selection factors may have excluded patients with serious arrhythmias at baseline from qualifying for the trial and receiving study drug (Table 3). 19. The potential contributing factors, occurrence rates, and management … We use cookies to help provide and enhance our service and tailor content and ads. The 24-hour Holter monitoring was performed pretreatment and at Weeks 0 (first day of dosing), 6, and 12. Abstract. 15. The most common arrhythmic events in the LABA treatment groups were tachycardia (0.3%-1.7% vs. 1.4% in the placebo group), ventricular extrasystoles (0.3%-1.7% vs 1.4% in the placebo group), and ventricular tachycardia (0.3%-1.0% vs. 1.4% in the placebo group) (Table 8). With respect to more serious arrhythmias, the proportion of patients with nonsustained ventricular tachycardia was small, with no evidence of a dose response for arformoterol. Mortality in COPD: role of comorbidities. 800-638-3030 (within USA), 301-223-2300 (international). The medical histories revealed that the 293 patients randomized to the placebo group had fewer overall cardiac disorders and coronary artery disorders than the 1163 patients randomized to the LABA groups (Table 1). We assessed the proportion of patients with each of 4 arrhythmias: atrial tachycardia, atrial fibrillation/flutter, and "nonsustained"; (4-10 beats) and "sustained"; (>10 beats) ventricular tachycardia. 4 The estimated prevalence of ischemic heart disease (IHD) in COPD patients varies between 20% and 60%, whereas the prevalence of heart failure (HF) lies between 10% and 30% and cardiac arrhythmias between 15% and 30% in most studies and systematic reviews. National Heart Lung and Blood Institute. However, at least 1 study has suggested FEV1 compromise is independently associated with increased risk of ventricular tachycardia9.

Egyptian Journal of Chest Diseases and Tuberculosis, https://doi.org/10.1016/j.ejcdt.2013.05.005. Although asymptomatic in its early stages, COPD is characterized by a gradual and progressive loss of lung function, and is an independent risk factor for ventricular arrhythmia9 and cardiovascular morbidity and mortality16,28,29. Atrial fibrillation, also known as AFib, is the most common heart rhythm disorder (arrhythmia). All registration fields are required. Chronic obstructive pulmonary disease surveillance-United States, 1971-2000. Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease that causes obstructed airflow from the lungs. 25.

The … Global strategy for the diagnosis, management, and prevention of chronic obstructive pulmonary disease: GOLD executive summary. Most patients were male (59%), white (95%), had an average age of approximately 63 years, and had moderate to severe COPD (mean forced expiratory volume in 1 s [FEV1], 1.2 L; mean predicted FEV1, ∼41%). 13. 12. Chronic obstructive pulmonary disease. Patients were then randomized to 1 of the following 5 treatment groups for 12 weeks: a) arformoterol (Sepracor Inc., Marlborough, MA) 15 μg twice daily; b) arformoterol 25 μg twice daily; c) arformoterol 50 μg once daily; d) salmeterol (Serevent inhalation aerosol, GlaxoSmithKline, Research Triangle Park, NC) metered-dose inhaler 42 μg twice daily; or e) placebo. While no statistically significant differences were observed (p > 0.71), the proportion of patients with episodes of atrial tachycardia not present at baseline was slightly higher in the LABA groups than in the placebo group (by ∼2%-5%). Copyright © 2013 The Egyptian Society of Chest Diseases and Tuberculosis. Other risk factors may include: 1. indoor air pollution (such as solid fuel used for cooking and heating) 2. outdoor air pollution 3. occupational dusts and chemicals (such as vapours, irritants, and fumes) 4. frequent lower respiratory infections during childhood.Many cases of COPD are preventable. Your message has been successfully sent to your colleague. Few patients had >10 beat ventricular tachycardia, with no suggestion of an arformoterol dose response for this arrhythmia. Cigarette smoking is a common risk factor for COPD. … Women, having proportionately smaller lungs and airways than men, are more likely to develop symptoms of COPD. In another normative aging study among 423 healthy ambulatory adults aged 75-85 years followed for 10 years, Frishman et al12 reported a lower prevalence of paroxysmal atrial tachycardia (13%) than the current study, but a similar occurrence frequency (5%) of nonsustained ventricular tachycardia.

We found negative significant correlation between O2 tension and the occurrence of fatal arrhythmias; the same as between O2 tension and QTd value (P values were <0.0005 in both), with QTd as the dependent variable, and age, pulmonary pressure, duration, Mg, Na, K, Hb PH, CO2 and O2 tensions as the independent variables in all subjects, it was shown that only PaO2 was the predictor of QTd with a P value of 0.02. Atrial fibrillation, also known as AFib, is the most common heart rhythm disorder (arrhythmia). 3–6 CVD comorbidity is not limited to … Registered users can save articles, searches, and manage email alerts. This small excess of atrial tachycardia in the LABA groups was stable over the 12 weeks of treatment (ranging from 14% to 16% in the placebo group, and from 15% to 19% in the LABA groups; Table 5). Comorbid cardiovascular conditions associated with tobacco smoking and/or aging occur frequently in patients with COPD. Cardiac safety of formoterol 12 microg twice daily in patients with chronic obstructive pulmonary disease. In patients receiving corticosteroids or xanthines, the dose must have been stable for 14 days before study entry. In this assessment, "sustained"; ventricular tachycardia was based on a minimum number of consecutive ventricular beats, not the presence of runs within a specific duration of time. Significant cardiac risk factors in the ITT population included abnormal glucose metabolism (11%), lipid disorders (23%), hypertension (37%), and current or previous tobacco use (100%). Baseline Holter monitoring was performed in all patients entering the 2-week single-blind placebo run-in period, whether or not they were randomized to treatment. 18. The 95% confidence intervals (CIs) and statistical tests were performed based on exact distribution methods1. Atrial tachycardia occurred frequently (41.8%). Inhaled formoterol dry powder versus ipratropium bromide in chronic obstructive pulmonary disease. All treatment groups (LABA and placebo) had consistent small decreases from baseline in mean 24-hour and maximum hourly heart rate. Medical history conditions were coded using terms from the Medical Dictionary for Regulatory Activities version 9.1 (MedDRA) summarized by system organ class, high level group term, high level term, and preferred term. Finally, the initial Holter interpretations did not a priori place arrhythmias into the categories described in this report. Cigarette smoking is usually cited as the most common risk factor for COPD. 4. The proportion of patients with atrial tachycardia in the nonrandomized population (40.7%) was similar to the ITT population at baseline. Chronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide. We do not believe that the retrospective assignment of arrhythmia categories was biased as the assignment was performed independently, and without knowledge of treatment, by 2 physicians who utilized the Holter interpretation of the cardiologist and the total number of beats in the arrhythmia run. Because the study designs, patient populations, safety, and efficacy endpoints in each trial were identical, the data were combined to provide more stable estimates of infrequent arrhythmia events, such as atrial fibrillation and ventricular tachycardia, than either trial analyzed separately. There were 5226 Holter recordings in 1429 treated patients. Another limitation to be considered in the interpretation of these trial results is that all patients, including those in the placebo group, were allowed the use of albuterol and ipratropium as rescue medications for acute symptom relief. The prevalence of these arrhythmias was similar to that previously reported in healthy elderly populations, with the possible exception of atrial fibrillation, which was less frequently observed than in prior reports. Each Holter record was interpreted in a blinded fashion by cardiologists at a central electrocardiogram laboratory (SpaceLabs Medical Data, Issaquah, WA). Adverse events (9% overall) were the most common reason for patient discontinuation. 3,4 Cardiovascular disease is the most common comorbid condition in COPD patients, which usually develops into heart failure and is a major cause of death in these patients. Inhaled beta2-adrenergic agonists have been reported to increase heart rate and contribute to the occurrence of arrhythmias, as suggested in a 2004 meta-analysis25. The proportions with atrial fibrillation/flutter (2.7%), >10 beat ventricular tachycardia (1.8%), and nonsustained ventricular tachycardia (7.9%), however, were higher in the nonrandomized compared with the ITT population. Published by Wolters Kluwer Health, Inc. Other demographic variables were well balanced among the treatment groups. At baseline, there was a high rate of atrial tachycardia in the ITT population (41.8%). A total of 1178 (81%) patients completed the studies (ranging from 77% to 85% across the treatment groups). Fatal arrhythmias are a common cause of death in chronic obstructive pulmonary disease (COPD). It is unclear whether these comorbidities are due to the disease itself27,28, its associated risk factors8,26,31, or its treatment24. COPD can damage lung tissue. Arrhythmias that occur in the atria (the top chambers of the heart) are supraventricular (above the ventricles) in origin. 16. Please enable scripts and reload this page. The rates of the other more serious arrhythmias did not increase with LABA treatment and were similar to placebo. Baseline Clinical Characteristics and Medical Histories*, Proportion of Patients With Holter Arrhythmia Events at Baseline*, Cumulative Proportion of COPD Patients With Treatment-Emergent (Not Present at Baseline) Holter Arrhythmia Events Over 12 Weeks of Treatment, Proportion of Patients at Weeks 0 (Post-First Dose), 6, and 12 With Treatment-Emergent (Not Present at Baseline) Holter Arrhythmia Events, Cumulative Proportion of COPD Patients With Holter Arrhythmia Events Present Over 12 Weeks of Treatment, Proportion of Patients at Weeks 0 (Post-First Dose), 6, and 12 With Holter Arrhythmia Events Present at Each Visit Including Baseline, Patients With Treatment-Emergent Cardiovascular Adverse Events. Changes (and 95% CIs) from baseline in mean heart rate (over 24 hours) and maximum mean hourly heart rate (highest mean hourly heart rate in the 24-hour period) as measured by 24-hour Holter monitoring were presented.

Arrhythmias in patients with chronic obstructive pulmonary disease. The rates of serious cardiovascular events (0.7%-1.4%) were similar in the LABA and placebo groups, but the proportion of patients who discontinued due to cardiovascular adverse events was slightly higher in those with LABA treatment (3.8%) compared to those with placebo (1.7%; p = 0.101). Sin DD, Man SF. Eligible patients were entered into a 2-week single-blind placebo run-in period. The percentage of patients with cardiovascular adverse events was 11.2%. Please try after some time. The proportion of patients with treatment-emergent atrial tachycardia ranged from 27% to 32% and was non-significantly higher, by ∼2%-5% (p = 0.70), in the LABA groups compared with the placebo group. Whether these results imply that arrhythmia risk is related more to underlying comorbidities than to airway function compromise is not known. 27. Hanrahan, Grogan, Baumgartner, Wilson, and Mr. Cheng were full-time employees of Sepracor Inc. when the study was conducted. Dr. Baumgartner is currently at Inotek Pharmaceuticals Corp., Beverly, MA. She says she woke this morning feeling fine but experienced increasing dyspnea over the past six hours that’s unrelieved with use of her metered-dose inhalers (MDIs). AFib can cause blood to pool in the atria, which can lead to blood clots, stroke, and heart failure. to maintaining your privacy and will not share your personal information without Patients with MAT frequently have significant comorbidities, especially chronic obstructive pulmonary disease (COPD) and respiratory failure, and are often treated in ICUs. Patients were randomized to LABA treatment or placebo for 12 weeks: a) nebulized arformoterol 15 μg BID, b) 25 μg BID, or c) 50 μg QD; d) salmeterol metered dose inhaler 42 μg BID; or e) placebo. Few studies have had an adequate number of patients and sufficient duration of monitoring to characterize the occurrence of transient and infrequent arrhythmias such as atrial fibrillation and ventricular tachycardia. Recent estimates are that more than 12 million adults are currently diagnosed with COPD, and that the actual prevalence may be more than double that number23. Comparisons between all intent-to-treat (ITT) patients and nonrandomized patients at baseline were performed using the Fisher exact test. At baseline, there was a low frequency of occurrence of atrial fibrillation/flutter (0.1%), nonsustained ventricular tachycardia (3.1%), and >10 beat ventricular tachycardia (0.3%). Hanrahan, John P. MD, MPH; Grogan, Donna R. MD; Baumgartner, Rudolf A. MD; Wilson, Amy PhD; Cheng, Hailong MS; Zimetbaum, Peter J. MD; Morganroth, Joel MD. Anesthesia is associated with cardiac arrhythmias for several reasons, including : Abbreviations: bpm = beats per minute, CI = confidence interval, COPD = chronic obstructive pulmonary disease, FEV1 = forced expiratory volume in 1 second, FVC = forced vital capacity, ITT = intent-to-treat, LABA = long-acting beta2-agonist, MedDRA = Medical Dictionary for Regulatory Activities. Major exclusion criteria were the use of non-protocol-specified beta-agonists; life-threatening/unstable respiratory status within 30 days before screening; asthma or any chronic respiratory disease other than COPD; lung resection of more than 1 full lobe; and/or continuous supplemental oxygen (unless the patient resided at elevation ≥4000 feet). The primary cause of COPD is tobacco smoke (including second­hand or passive exposure). Atrial fibrillation (AF) is one of the most common arrhythmias and causes substantial morbidity and mortality. Chronic obstructive pulmonary disease (COPD) is a significant and increasing cause of death in the United States20,21. World Medical Association Declaration of Helsinki. Smoking is the most common cause and the greatest risk factor for COPD, resulting in as many as 90 percent of deaths. Treatment with inhaled LABA therapy in these trials did not increase the occurrence of serious arrhythmias, and did not result in a mean increase in heart rate as assessed by 24-hour Holter monitoring. Some error has occurred while processing your request. A total of 1829 patients met eligibility at the screening visit and received single-blind placebo; 364 patients were not randomized, 329 of whom had a baseline Holter assessment (nonrandomized patients). In terms of diagnosed cases, this makes COPD the second most common lung disease in the UK, after asthma. Chronic obstructive pulmonary disease (COPD) is one of the most important comorbidities of CVD, which causes serious consequences in patients with ischemic heart disease, stroke, arrhythmia, and heart failure. The 24-hour Holter monitoring was performed pretreatment and at Weeks 0 (first day of dosing), 6, and 12. When asked specifically, she says her dyspnea gets worse with exertion, but she feels “almost normal” when sitting down. The Authors. The institutional review boards at each study site approved each protocol, and written informed consent was obtained from all participants. All patients had moderate to severe COPD, and those with stable cardiac or other comorbidities were not excluded from the study cohort. [email protected]. This website uses cookies. Bestall JC, Paul EA, Garrod R, Garnham R, Jones PW, Wedzicha JA. 29. 26. An estimated 1.2 million people are living with diagnosed COPD – considerably more than the 835,000 estimated by the Department of Health in 2011. Most of the time, these Arrhythmias can be non-threatening, but there are instances where they can cause a few fatal conditions. Baseline heart rate was similar across groups (81.1-82.8 beats per minute [bpm]). You may be trying to access this site from a secured browser on the server.

The 2 trials were identically designed Phase III multicenter randomized trials. A complete description of the methodology has been reported previously2,14. A high proportion of patients had runs of atrial tachycardia at baseline, while few had more serious arrhythmias such as afibrillation/flutter, nonsustained ventricular tachycardia, and >10 beat ventricular tachycardia. Ferguson GT, Funck-Brentano C, Fischer T, Darken P, Reisner C. Cardiovascular safety of salmeterol in COPD. More patients who received LABAs also discontinued due to cardiovascular adverse events (3.8%) than those in the placebo group (1.9%). LABA administration did not increase mean heart rate. Efficacy of salmeterol xinafoate in the treatment of COPD. Holter monitoring was performed using a Burdick 6732 digital 3-channel Holter monitor at baseline (the first 24-hour period at the start of the 2-week single-blind placebo run-in), after the first dose at Week 0, and at Weeks 6 and 12. Overall, the proportion of LABA-treated patients with treatment-emergent (i.e., not present at baseline) nonsustained ventricular tachycardia was similar to placebo (p = 0.86), and atrial fibrillation/flutter and >10 beat ventricular tachycardia were rarely observed in all groups (Table 4). may email you for journal alerts and information, but is committed Patterns of comorbidities in newly diagnosed COPD and asthma in primary care. These arrhythmias are not responsible for dramatic events such as sudden cardiac death, but the most common arrhythmia, atrial fibrillation, is supraventricular and … There were 60 sites in the first study and 64 sites in the second study. Although asymptomatic in its early stages, COPD is characterized by a gradual and progressive loss of lung function, and is an independent risk factor for ventricular arrhythmia9 and cardiovascular morbidity and mortality16,28,29. These are the five most common symptoms of COPD: • Coughing. These medications were available to all patients, including those in the placebo group, as needed during the entire study period. Baseline was calculated from the 24-hour Holter records obtained at the start of the placebo run-in period 2 weeks before study drug administration. More serious arrhythmias were infrequent and did not increase with inhaled LABA therapy. 800-638-3030 (within USA), 301-223-2300 (international) For more information, please refer to our Privacy Policy. Usefulness of the Medical Research Council (MRC) dyspnoea scale as a measure of disability in patients with chronic obstructive pulmonary disease. This conclusion is supported by both the absence of a dose response with arformoterol and the lack of a statistically significant difference among the treatment groups. The effect of inhaled long-acting beta2-agonists (LABAs) on these outcomes was evaluated in patients with chronic obstructive pulmonary disease (COPD) in 2 double-blind randomized clinical trials.

Genomewide linkage analysis of quantitative spirometric phenotypes in severe early-onset chronic obstructive pulmonary disease. In this study, we attempted to non-invasively verify these hypotheses in hypoxaemic COPD patients that are not in respiratory failure by examining how PaO2, PaCO2, pH and HCO3 correlate with QTd in those patients. Nebulized arformoterol in patients with COPD: a 12-week, multicenter, randomized, double-blind, double-dummy, placebo- and active-controlled trial. Emerging risk factors for the development of AF include a variety of breathing disorders like COPD. During treatment, more patients in the placebo group used rescue albuterol (post-first dose, 35.8%; Week 6, 30.4%; Week 12, 28.0%) than patients in the active treatment groups throughout the monitoring period (range post-first dose, 20.5%-25.3%; range Week 6, 18.4%-20.3%; range Week 12, 17.1%-25.7%). Patients taking beta-blockers were also excluded. There is a high positive significant correlation between the age of patients, duration of COPD and Hb level and the occurrence of fatal arrhythmias where P values were 0.009, <0.0005 and <0.0005 respectively; the same as with QTd value where the P values were 0.015, 0.001 and 0.039. The fact that the majority of the arrhythmias were atrial fibrillation and flutter is consistent with the fact that this is the most common sustained arrhythmia encountered in clinical practice, 35 Sra J COPD patients are more likely to be diagnosed with CVD than the general population (odds ratio of 2.46). 24. 6.

The occupational burden of chronic obstructive pulmonary disease. While increases in the number of patients with atrial fibrillation/flutter were observed with increasing doses of arformoterol, only a small proportion of patients was affected in each treatment group (0.3%-1.4%). We believe this was unlikely, as only a small percentage of patients in each treatment group discontinued due to cardiovascular adverse events, and the overall incidence of cardiovascular adverse events was similar across the treatments with no clear dose-response among arformoterol-treated patients. The highest proportion of withdrawals occurred in the placebo (21.8%) and arformoterol 25 μg BID groups (23.3%). They were double-blind, double-dummy, placebo- and active-controlled, parallel-group, 12-week multiple-dose clinical trials. Mahler DA, Donohue JF, Barbee RA, Goldman MD, Gross NJ, Wisniewski ME, Yancey SW, Zakes BA, Rickard KA, Anderson WH. This could have contributed to an underestimation of arrhythmia occurrence with longer duration of LABA treatment. Data is temporarily unavailable. Based on these interpretations, 2 board-certified internal medicine physicians at Sepracor Inc. retrospectively, but independently and blinded to treatment, categorized each overread Holter into 4 major arrhythmia categories: atrial tachycardia (≥4 beat run), atrial fibrillation/flutter, "nonsustained"; ventricular tachycardia (4-10 beat run), and "sustained"; ventricular tachycardia (>10 beat run). Conduction abnormalities were the most common ECG abnormality in COPD patients (28%) being significantly more prevalent than in patients without COPD (11%, p < 0.001). 17. COPD is associated with many comorbidities [ 2 , 3 ] ( figure 1 ) and can be one of multiple chronic or acute diseases and medical conditions present within one person [ 4 ]. 14. And if air leaks into the space between a lung and your chest wall, that lung can collapse like a deflated balloon. This review summarises the current knowledge on the different aspects of COPD exacerbations. AFib may happen in short bursts, last until treated, or might be a permanent condition. Fleg JL, Kennedy HL. From Sepracor Inc. (JPH, DRG, RAB, AW, HC), Marlborough, Massachusetts; Beth Israel Deaconess Medical Center (PJZ), Harvard Medical School, Boston, Massachusetts; University of Pennsylvania School of Medicine (JM) and eResearch Technology, Inc. (JM), Philadelphia, Pennsylvania. The number and percentage of patients who used rescue albuterol and supplemental ipratropium during the 24-hour Holter monitoring period were calculated for each assessment time. Nevertheless, use of inhaled short-acting beta2-agonists may have affected the occurrence of arrhythmias observed in all groups, especially the placebo group. 25 COPD patients were subjected for Standard 12-lead ECG for arrhythmia detection and the measurement of QT intervals, chest X-ray, two dimensional echocardiography and myocardial nuclear imaging to exclude IHD. The results are consistent with other studies in which the prevalence of arrhythmias following LABA treatment was determined by 24-hour ambulatory monitoring4,10. Glasser SP, Clark PI, Applebaum HJ. Management of COPD. 32. Yet these drugs, especially nonselective beta-agonists, directly increase the rate and vigor of cardiac contractions. The mean change from baseline over 24 hours in the active treatment groups was similar (difference of <2 bpm) to placebo over all post-baseline visits (post-first dose, Week 6, and Week 12), with little change observed over time (Table 2). Cardiac arrhythmias are quite common in people who are undergoing general anesthesia. By continuing you agree to the use of cookies. Yet even among all patients evaluated, the prevalence of atrial fibrillation was lower than that reported in a previous large longitudinal study (5.5%)15. Occurrence of frequent complex arrhythmias detected by ambulatory monitoring: findings in an apparently healthy asymptomatic elderly population. Chronic obstructive pulmonary disease as a risk factor for cardiovascular morbidity and mortality. Two studies were conducted between February 2002 and March 2004 under United States Food and Drug Administration regulations, which include principles established by Good Clinical Practice and the Declaration of Helsinki and its amendments32. In conclusion, the current study describes the occurrence frequency of 24-hour Holter-assessed arrhythmias in a large cohort of patients with moderate to severe COPD with no or stable cardiac comorbidities and the impact of LABA treatment on these arrhythmias. Recent guidelines6,18,24 recommend the use of long-acting bronchodilators, including long-acting beta2-agonists (LABAs), for maintenance treatment of moderate and more severe COPD. Consequently, a high mortality rate (ie, up to 45%) is associated with this arrhythmia, although it is not a direct consequence of the rhythm abnormality. Arrhythmias are common in most people who have undergone heart surgery or a coronary stent procedure or are genetically carrying a structural defect in the heart. 5. Our results rule out the electropathy hypothesis and underline autonomic neuropathy as the most possible mechanism of arrhythmias in hypoxaemic, non-respiratory failure, and COPD patients. Arrhythmic adverse events occurred in 4.4% of patients in the placebo group and in 3.1%-5.5% of patients in the LABA groups. Address reprint requests to: Amy Wilson, PhD, Sepracor Inc., 84 Waterford Drive, Marlborough, MA 01752. 30. Available at. Beta-adrenergic stimulation may increase heart rate and the potential for cardiac arrhythmias. They also observed that nonsustained ventricular tachycardia among these healthy elderly was associated with a higher relative risk of subsequent death (RR, 2.8; 95% CI, 1.2-6.4). We assessed the proportion of patients with each of 4 arrhythmias: atrial tachycardia, atrial fibrillation/flutter, and "nonsustained"; (4-10 beats) and "sustained"; (>10 beats) ventricular tachycardia. Eisner MD, Balmes J, Katz PP, Trupin L, Yelin EH, Blanc PD. It's caused by long-term exposure to irritating gases or particulate matter, most often from cigarette smoke. Ventricular tachycardia occurs when the ventricles start pounding away at up to 200 bpm—a disruption that can cause dizziness and breathlessness. Changes in the maximum hourly mean heart rate were also stable (difference of <2 bpm) across groups and visits (Table 2). Chronic obstructive pulmonary disease (COPD) is a progressive condition that makes it hard to breathe. Patients were given guidance on their use throughout the trial and were instructed to withhold them for 6 hours before clinic visits. This implies that selection factors may have excluded patients with serious arrhythmias at baseline from qualifying for the trial and receiving study drug (Table 3). 19. The potential contributing factors, occurrence rates, and management … We use cookies to help provide and enhance our service and tailor content and ads. The 24-hour Holter monitoring was performed pretreatment and at Weeks 0 (first day of dosing), 6, and 12. Abstract. 15. The most common arrhythmic events in the LABA treatment groups were tachycardia (0.3%-1.7% vs. 1.4% in the placebo group), ventricular extrasystoles (0.3%-1.7% vs 1.4% in the placebo group), and ventricular tachycardia (0.3%-1.0% vs. 1.4% in the placebo group) (Table 8). With respect to more serious arrhythmias, the proportion of patients with nonsustained ventricular tachycardia was small, with no evidence of a dose response for arformoterol. Mortality in COPD: role of comorbidities. 800-638-3030 (within USA), 301-223-2300 (international). The medical histories revealed that the 293 patients randomized to the placebo group had fewer overall cardiac disorders and coronary artery disorders than the 1163 patients randomized to the LABA groups (Table 1). We assessed the proportion of patients with each of 4 arrhythmias: atrial tachycardia, atrial fibrillation/flutter, and "nonsustained"; (4-10 beats) and "sustained"; (>10 beats) ventricular tachycardia. 4 The estimated prevalence of ischemic heart disease (IHD) in COPD patients varies between 20% and 60%, whereas the prevalence of heart failure (HF) lies between 10% and 30% and cardiac arrhythmias between 15% and 30% in most studies and systematic reviews. National Heart Lung and Blood Institute. However, at least 1 study has suggested FEV1 compromise is independently associated with increased risk of ventricular tachycardia9.

Egyptian Journal of Chest Diseases and Tuberculosis, https://doi.org/10.1016/j.ejcdt.2013.05.005. Although asymptomatic in its early stages, COPD is characterized by a gradual and progressive loss of lung function, and is an independent risk factor for ventricular arrhythmia9 and cardiovascular morbidity and mortality16,28,29. Atrial fibrillation, also known as AFib, is the most common heart rhythm disorder (arrhythmia). All registration fields are required.

The … Global strategy for the diagnosis, management, and prevention of chronic obstructive pulmonary disease: GOLD executive summary. Most patients were male (59%), white (95%), had an average age of approximately 63 years, and had moderate to severe COPD (mean forced expiratory volume in 1 s [FEV1], 1.2 L; mean predicted FEV1, ∼41%). 13. 12. Chronic obstructive pulmonary disease. Patients were then randomized to 1 of the following 5 treatment groups for 12 weeks: a) arformoterol (Sepracor Inc., Marlborough, MA) 15 μg twice daily; b) arformoterol 25 μg twice daily; c) arformoterol 50 μg once daily; d) salmeterol (Serevent inhalation aerosol, GlaxoSmithKline, Research Triangle Park, NC) metered-dose inhaler 42 μg twice daily; or e) placebo. While no statistically significant differences were observed (p > 0.71), the proportion of patients with episodes of atrial tachycardia not present at baseline was slightly higher in the LABA groups than in the placebo group (by ∼2%-5%). Copyright © 2013 The Egyptian Society of Chest Diseases and Tuberculosis. Other risk factors may include: 1. indoor air pollution (such as solid fuel used for cooking and heating) 2. outdoor air pollution 3. occupational dusts and chemicals (such as vapours, irritants, and fumes) 4. frequent lower respiratory infections during childhood.Many cases of COPD are preventable. Your message has been successfully sent to your colleague. Few patients had >10 beat ventricular tachycardia, with no suggestion of an arformoterol dose response for this arrhythmia. Cigarette smoking is a common risk factor for COPD. … Women, having proportionately smaller lungs and airways than men, are more likely to develop symptoms of COPD. In another normative aging study among 423 healthy ambulatory adults aged 75-85 years followed for 10 years, Frishman et al12 reported a lower prevalence of paroxysmal atrial tachycardia (13%) than the current study, but a similar occurrence frequency (5%) of nonsustained ventricular tachycardia.
