Study on Clinical Profile of Patients with Atrial Fibrillation at a Tertiary Care Hospital in Mandya

Introduction: Atrial fibrillation is the most common arrthymia and accounts for 1/3 of hospital admissions for cardiac rhythm disturbance. Recent epidemiological data have reaffirmed the fact that AF is a global epidemic and has adverse effect on long term morbidity and mortality. Aims: To determine clinical profile of patients admitted with AF and to determine etiology of atrial fibrillation. To determine the mortality and morbidity of patients admitted with atrial fibrillation. Materials and Methods: A prospective observational study was carried out in 100 cases of atrial fibrillation admitted at Mandya institute of medical sciences during a time period of 12 months from January 2019 to January 2020. A detailed history and clinical examination were done according to prepared proforma. All the required investigation was collected and analysed. Results: Out of 100 cases 63 were female and male 37. Mean age was 54.98 years, most of the patients were in the age group 41-60 year (45%). Dyspnoea was the most common presentation in 71 %, followed by palpitation in 66%. Most common cause of AF was RHD 49% in our study followed by CAD in 20% and hypertension in 15%. Commonest valvular pathology in our study was mitral regurgitation (MR) in 51%. Most common valvular lesion in RHD was mitral stenosis (MS) 93.8%. Complications in the study were congestive cardiac failure in 68% and stroke in 9 %. Mortality in our study was 2%. Conclusions: In our study females were more than males. Majority of patients belonged to 41-60 years age group.
