Studies conducted in India have shown wide variations in atrial fibrillation prevalence, ranging from 0.1 to 1.6 (%). Unfortunately, in India population-based information on atrial fibrillation is limited. Moreover, the available knowledge on atrial Fibrillation and oral anticoagulation (OAC) practices are largely derived from the hospital-based studies.
Recent study in Indian Heart Journal conducted a community-based cross-sectional study done in rural Andhra Pradesh (AP). Adults from 40 villages formed the study population. Door-to door survey was performed to collect information on demographics, and medical history. Electrocardiogram was recorded using a smart phone based device. Participants diagnosed with AF underwent echocardiogram. Study cardiologists assessed the cardiovascular risk profile and collected detailed medical history.
Fourteen of the 4281 individuals screened had AF. The study results showed that except for one, all were non-valvular atrial fibrillation. Three had history of stroke. Two were on anticoagulant therapy.
The prevalence of AF is lower in this study compared to studies from the developed countries. Non-rheumatic cardiovascular risk factors were primary causes for atrial fibrillation. So the authors concluded that non-adherence to stroke prophylaxis is a major threat that needs to be addressed.
