PURPOSE: To estimate the prevalence of arrhythmias and associated cardiovascular conditions in Russian patients with chronic obstructive pulmonary disease (COPD).
METHODS: 168 hospitalized men with exacerbation of COPD were included in this study. The mean age of the patients was 62.9±10.1 years. All the patients underwent physical examination. Also laboratory tests (LDL-cholesterol, whole capillary blood glucose) and instrumental investigations (electrocardiography, echocardiography, ambulatory 24-hour Holter recording) were performed.
RESULTS: Supraventricular arrhythmias was detected in 23.8% of cases (40 patients): atrial fibrillation - in 16.8% (28 patients), atrial premature complexes - in 7.1% (12 patients). Ventricular arrhythmias (ventricular premature complexes) was detected in 5.9% (10 patients). All patients with arrhythmias were cigarette smokers (mean smoking history was 39.8±8.9 pack-years). Associated cardiovascular conditions were revealed in 26 patients (65% of cases) with arrhythmias. History of myocardial infarction and angina were detected in 8 patients (20% of cases), arterial hypertension in 6 patients (15% of cases) and pulmonary hypertension in 12 patients (30% of cases) with arrhythmias.
CONCLUSION: Our study confirmed high prevalence of arrhythmias in Russian patients with COPD. Also our study confirmed high prevalence of associated cardiovascular conditions in COPD patients with arrhythmias.
CLINICAL IMPLICATIONS: Physicians should detect and treat these conditions to prevent severe complications and increase quality of life in COPD patients.
