Abstract

Coronary artery disease is the most prevalent form of heart disease. It along with its complications are a leading cause of morbidity and mortality among the world population. Coronary artery bypass grafting is done in significant (>50%) stenosis of all major coronary trunks and their branches. The burden of atrial fibrillation varies from one population to another among patients subjected to CABG.


OBJECTIVE:


To determine the frequency of atrial fibrillation after coronary artery bypass grafting.


MATERIALS AND METHODS:


            This Descriptive cross-sectional study was conducted in the Cardiovascular Surgery unit of a tertiary care hospital in Peshawar over six months. A total of 144 patients were observed. All patients underwent CABG surgery by the same cardiovascular surgeon. All patients were observed till ten days post operation through daily ECG to detect atrial fibrillation.


RESULTS:


A total of 144 patients were observed of which 33% of patients were in age 50-60 years and 67% patients were in age 61-75 years. The mean age was 63 years with SD ± 8.33.  Sixty-nine percent of patients were male and 31% of patients were female.  More than 17% of patients had atrial fibrillation while 83% of patients didn’t have atrial fibrillation.


CONCLUSION:


Our results show that 17% of patients developed atrial fibrillation following CABG surgery, emphasizing the importance of this arrhythmia throughout the recovery phase. A distinct age pattern was seen, with a significant proportion of atrial fibrillation instances found in individuals between 61 and 75 years old.
