Objective: To identify the risk factor profile of Atrial Fibrillation applying CHA2DS2-VASC scoring system Study Design: Descriptive cross-sectional study. Place and Duration of Study: The study was conducted in outdoor patient and emergency departments of Armed Forces Institute of Cardiology/National Institute of Heart Diseases in 4 months duration after approval of synopsis, from Sep 2019 to Dec 2019. Methodology: All patients with symptoms of palpitation and dyspnea were evaluated with detailed history, physical examination, electrocardiogram and 2-D echocardiography for collection of data. Patients who were found with Atrial Fibrillation on electrocardiogram and non-valvular on 2-D echocardiography were enrolled. Detailed History regarding CHA2DS2-VASC scoring system was taken. Patients with age <18 years, those with moderate rheumatic stenos is, hypertrophic cardiomyopathy and Atrial Fibrillation with prosthetic valves were excluded. Data was entered and analyzed with SPSS-23. Results: Out of 100 patients enrolled, frequencies of male and female patients were 60 (60%) and 40 (40%) respectively. The age varied from 25 years to 89 years with a mean age of 64.27 ± 12 years. Maximum number of patients was between 65-74 years (31%). Hypertension (57%) was the most common risk factor after gender followed by age. Frequencies of other risk factors were congestive heart failure (33%), diabetes mellitus (18%), vascular disease (14%) and stroke/TIA/thrombo-embolism (13%). Paroxysmal atrial fibrillation was the most common type of atrial fibrillation observed (67%) followed by persistent atrial fibrillation (31%). The number of patients having CHA2DS2-VASC score 2 and greater than 2 were 76 (76%) and less than 2 were 24%. Conclusion: Our findings highlighted the prevalence of non-modifiable as well as modifiable predictors of thromboembolic phenomena in atrial fibrillation using CHA2DS2-VASC scoring system in our population.
