These medications improve objective measures of lung function, reduce symptom severity, and enhance quality of life2,7,19,24. Usefulness of the Medical Research Council (MRC) dyspnoea scale as a measure of disability in patients with chronic obstructive pulmonary disease. 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. Inhaled formoterol dry powder versus ipratropium bromide in chronic obstructive pulmonary disease. Campbell SC, Criner GJ, Levine BE, Simon SJ, Smith JS, Orevillo CJ, Ziehmer BA. Cardiac arrhythmias are quite common in people who are undergoing general anesthesia. Severe exacerbations are related to a significantly worse survival outcome. 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. 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%). 3. Support for this study provided by Sepracor Inc., Marlborough, MA. Copyright © 2013 The Egyptian Society of Chest Diseases and Tuberculosis. 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. 24. 32. 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. 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. 21 However, neither the … The primary cause of COPD is tobacco smoke (including secondhand or passive exposure). Patients may have had more than 1 of these abnormalities during any 24-hour Holter monitoring period. National Institutes of Health website. Soriano JB, Visick GT, Muellerova H, Payvandi N, Hansell AL. Proportions were based on the number of patients with data at each assessment time. Albuterol metered dose inhaler (Ventolin inhalation aerosol, GlaxoSmithKline, Research Triangle Park, NC) and ipratropium metered dose inhaler (Atrovent inhalation aerosol, Boehringer Ingelheim, Ridgefield, CT) were provided as rescue and supplemental medications for COPD, respectively. Inhaled beta-agonists are among the first treatment options for the management of COPD. 9. Get new journal Tables of Contents sent right to your email inbox, November 2008 - Volume 87 - Issue 6 - p 319-328. 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). However, as noted above, patients who were not randomized in these clinical trials may not have had the same degree of preexisting arrhythmia risk as those who were randomized and received study drug. Abstract. 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. Whether these results imply that arrhythmia risk is related more to underlying comorbidities than to airway function compromise is not known. World Medical Association Declaration of Helsinki. The only cardiac exclusions were patients with clinically significant abnormal electrocardiograms at screening, or clinically significant cardiac disorders that in the opinion of the investigator would have interfered with the patient's ability to complete the study. The first relates to the composition of the COPD study cohort. And if air leaks into the space between a lung and your chest wall, that lung can collapse like a deflated balloon. Patients had lung-function compromise typical of patients with nonasthmatic COPD and were affected by comorbid medical conditions common in the elderly. Several limitations of these trials should be considered in the interpretation of these results. More patients who received LABAs also discontinued due to cardiovascular adverse events (3.8%) than those in the placebo group (1.9%). Two patients died from cardiovascular adverse events (abdominal aortic aneurysm [arformoterol 15 μg BID]; and type A aortic dissection [arformoterol 50 μg QD]). There is a positive significant correlation between pulmonary pressure and QTc where the P value was 0.041 and pulmonary pressure with QTd where the P value was 0.028. The potential contributing factors, occurrence rates, and management … All treatment groups (LABA and placebo) had consistent small decreases from baseline in mean 24-hour and maximum hourly heart rate. Sin DD, Man SF. Efficacy of salmeterol xinafoate in the treatment of COPD. 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). Fatal arrhythmias are a common cause of death in chronic obstructive pulmonary disease (COPD). Chronic coughing at least three months out of the year for two consecutive years is a primary symptom of COPD. Ferguson GT, Funck-Brentano C, Fischer T, Darken P, Reisner C. Cardiovascular safety of salmeterol in COPD. Eisner MD, Balmes J, Katz PP, Trupin L, Yelin EH, Blanc PD. Available at. Chronic obstructive pulmonary disease (COPD) is a significant and increasing cause of death in the United States20,21. Huiart L, Ernst P, Suissa S. Cardiovascular morbidity and mortality in COPD. In this analysis, 24-hour Holter monitoring data were pooled from 2 identically designed Phase III trials. Other risk factors include workplace exposure to inhaled irritants such as coal dust or cadmium. 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.

Alternatively, this decline may have been due to a nonspecific benefit of clinical trial participation that resulted in improvements in health status unrelated to drug therapy. 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.
