    ABSTRACT: The aim of the study is to describe the natural history of an unselected population of patients with atrial fibrillation (AF) currently attending primary care services in a single health-service area in Galicia, north-western Spain. AFBAR is a transverse prospective study in which 35 general practitioners within one health-service area have enrolled patients diagnosed with AF who presented at their clinics during a three-month recruiting period. Primary endpoints are mortality or hospital admission. Here we report the results of the first 7-month follow-up period. 798 patients (421 male) were recruited; mean age of cohort was 75 years old. Hypertension was the most prevalent risk factor (77%). 87% of the patients were both overweight and obese. Permanent AF was diagnosed in 549 patients (69%). In the follow-up period, 16.4% of the patients underwent a primary endpoint and the overall survival was 98%. The following independent determinants of primary endpoint were identified: change in AF status (Hazard Ratio (HR) 2.89 (95% confidence interval (CI) 1.28-6.55); p=0.011); ischemic heart disease (IHD) (HR 2.78 (95% CI 1.51-5.13); p=0.001); pre-recruitment hospital admission (HR 2.22 (95% CI 1.18-4.19); p=0.013); left ventricular systolic dysfunction (HR 2.19 (95% CI 1.11-4.32); p=0.023); or AF-related complications (HR 1.98 (95% CI 1.10-3.56); p=0.022). In the first 7-month follow-up period of patients with AF in a primary care setting the study identified several independent risk factors for mortality or hospital admission, i.e. change in AF status, ischemic heart disease, left ventricular systolic dysfunction, previous AF-related complications and hospital admission.
