Prevalence, clinical correlates and treatment of permanent atrial fibrillation among the elderly: insights from the first prospective population-based study in rural Greece.

Abstract：

:To investigate the prevalence of permanent atrial fibrillation (AF), its clinical associated conditions and treatment status in the elderly population in rural Greece. 720 people (46.1% males) older than 65 years (mean age: 72.5 +/- 5.7 years) living in four villages in rural Greece were screened with an electrocardiogram (response rate: 90.5%) for the presence of permanent AF. They underwent a physical examination, including blood pressure (BP) measurement, and body mass index (BMI) calculation, in addition to an interview about their medical history, physical activity, smoking habits, alcohol consumption and medication use. Subjects with AF for whom anticoagulants were contraindicated were identified and stroke risk stratification was performed using the CHADS2 algorithm. The prevalence of permanent AF was 5% (6.6% among men and 3.6% among women) and it increased with age. In the entire population, ECG evidence of myocardial ischaemia and ventricular premature beats were independently associated with the presence of permanent AF (OR 5.266; 95% CI 2.22-12.49, P = 0.0001 and OR 2.61; 95% CI 1.059-6.432, P = 0.037, respectively), while female sex was independently associated with the absence of the AF (OR 0.327; CI 0.147-0.729, P = 0.006). From those patients who were eligible for anticoagulation, 40.6% were treated with anticoagulants, 34.3% were given antiplatelets therapy and the rest received no antithrombotic treatment. This is the first prospective study demonstrating the prevalence, clinical correlates and treatment status of permanent AF in Greece. These results confirm the high prevalence of permanent AF among the elderly and underscore the issue regarding anticoagulants underutilization.
