Frequency of atrial fibrillation and its common clinical outcomes among patients presenting with acute myocardial infarction.
Pak Heart J Jan ;47(3):123-6.

Objective: To determine frequency of atrial fibrillation and its common clinical outcomes among patients presenting with acute myocardial infarction. Methodology: This descriptive cross-sectional study was conducted at Hayatabad Medical Complex, Peshawar from 1st May to 31st October 2013. Patients who were admitted with Acute Myocardial Infarction( STEMI and NSTEMI) were included. These patients were closely monitored and any episode of AF was recorded. Those patients who developed AF were closely monitored for common clinical outcomes in the form of stroke, VT, VF, and death for maximum of 7 days during hospital stay. The collected data was stored and analyzed in SPSS version 10.0 for windows. Mean+-SD was calculated for numerical variables like age. Frequencies and percentages were calculated for categorical variables like gender, AF, VT, VF, stroke, type of MI, and death. AF and its common+- clinical outcomes were stratified among age, gender, and type of MI to see the+- effect modifications. Results: Out of 241 patients with acute myocardial infarction, males were 137 (56%) while females were 104 (43.2%). The mean age of the patients was 60.47+-9.79 years. 174 (72.2%) patients had STEMI, while 67 (27.8%) patients had NSTEMI. Atrial fibrillation was found in 22 (9.1%) patients out of which, 22.7% had VF, followed by VT in 18.2% patients, while 18.2% patients died, and 13.6% patients sustained stroke. Conclusion: Atrial Fibrillation complicating acute myocardial infarction is common in our population. Such patients should be identified and closely monitored as they have got higher rate of complications and mortality during hospital course.
