Abstract

Objectives: To determine the frequency and contributing factors of atrialfibrillation in patients with first ischemic stroke. Methodology: This study included 150 patientswith first acute ischemic stroke. All the patients had electrocardiography to detect the presenceof atrial fibrillation. The patients were also labeled for risk factors like hypertension, congestiveheart failure, smoking, and hyperthyroidism, etc. Setting: Mayo Hospital Lahore. Duration ofStudy: 1st January 2013 to 30th June 2013. Type: Descriptive Cross Sectional. Results: Atrialfibrillation was present among 22 (14.6%) patients. Among patients with atrial fibrillation,smoking, congestive heart failure and hypertension were the most frequent risk factors whichwere present in 11 (50%), 6 (27%), and 5 (22.7%) patients, respectively. Conclusion: Frequencyof atrial fibrillation among patients with first ischemic stroke was high. Smoking, congestiveheart failure and history of coronary artery bypass grafting are frequent risk factors.
