Objectives: Atrial fibrillation (AF) is the most common sustained cardiac rhythm disorder associated with stroke. This study was done to describe risk factors, clinical features, and short-term outcomes of stroke patients with AF. Materials and Methods: This study was a part of the Indian Council of Medical Research funded “Ludhiana urban population based Stroke Registry.” Data were collected using WHO STEPS stroke method. All patients ≥18 years of age, who developed ischemic stroke between March 26, 2011, and March 25, 2013, were included in this study. Data about demographic details, clinical features, and risk factors were collected. The outcome was assessed at 28 days using modified Rankin scale (mRs) (good outcome: mRS ≤2; poor outcome >2). The statistical measures calculated were descriptive statistics, Chi-square test, Fischer's exact test, and independent t-test. Results: Of the total 7199 patients enrolled in the registry, data of 1942 patients who fulfilled inclusion criteria were analyzed, and AF was seen in 203 (10%) patients. AF patients were older (AF 62 ± 14 vs. non-AF 60 ± 15 years, P= 0.01), had more hypertension (AF 176 [87%] vs. non-AF 1396 [80%], P= 0.03), hyperlipidemia (AF 60 [32%] vs. non-AF 345 [21%], P= 0.001), coronary artery disease (AF 60 [30%] vs. non-AF 195 [11%], P< 0.0001), and carotid stenosis (AF 14 [7%] vs. non-AF 57 (3%), P= 0.02). They had worse outcome (mRS >2; AF 90 [50%] vs. non-AF 555 [37%], P= 0.001). Conclusions: Ten percent of stroke patients had AF. They were older, had multiple risk factors and worse outcome. There was no gender difference in this large cohort.
