A Study On Clinical And Etiological Profile In Patients Of Atrial Fibrillation In Tertiary Care Centre In Sothern Bihar

Introduction : Atrial fibrillation (AF) is a major risk factor for ischemic stroke, congestive heart failure and mortality. The prevalence of AF is influenced by age, gender, cardiovascular disease (CVD) such as valvular heart disease, and CV risk factors such as hypertension, diabetes, obesity, and insulin resistance. It was calculated that currently more than 3 million inhabitants of the USA suffer from atrial fibrillation and that this will increase to more than 7 million by 2050 Aim and Objective: To find the various symptoms and possible underlying etiological factors for Atrial fibrillation, both cardiac and non-cardiac in our population Methodology: An observational study was conducted in General Medicine department in Narayan Medical College and Hospital, Jamuhar. Detail study of etiology complication and clinical presentation of atrial fibrillation will be done in present study. Informed consent from each patient will be obtained. The patient screening done for the underlying causes, which may lead to AF and correlated with clinically and eco-cardio-graphically. A detailed and complete physical, systematic and laboratory examination was performed on each patient. Result: Maximum 79% of study subjects had RHD, 28% had DM, 4.5% study subjects had systemic hypertension, 4% subjects had CAD, 2.5% Subjects had COPD, 3% had hyperthyroid, whereas 9% had other etiological factors. Most common clinical features were enlarged LA Size (85.5%), Cardiac failure (41.5%), MS/MR (28.5%), Mitral/Aortic stenosis (18.5%) , decrease in ejection fraction (14%). While the least common clinical features were MR (1.5%), RWMA (9.5%), IVSD (11.5%). Conclusions: prevalence of chronic AF is still more common below the age of 50 years and this is mostly due to high prevalence of rheumatic heart disease in India as being the most common etiology of AF. CHF is the most common associated condition with chronic AF.
