FREQUENCY OF ATRIAL FIBRILLATION IN POST OPERATIVE CORONARY ARTERY BYPASS GRAFTING SURGERY

Abstract

Objective: To determine frequency of atrial fibrillation (AF) in post operative
coronary artery bypass grafting (CABG) surgery.

Methodology:This descriptive case series study was performed at Ch. Pervaiz
Elahi Institute of Cardiology Multan. After approval from local ethical committee,
289 patients fulfilling the inclusion criteria selected from the patients who have
undergone CABG surgery and were in intensive care unit of Chaudhary Pervaiz
Elahi Institute of cardiology were included. They were observed during hospital
stay for development of AF. Data was analyzed using SPSS Version 10.
Descriptive statistics was used to calculate mean and standard deviation for age.
Frequencies and percentages were calculated for final out come i.e atrial
fibrillation. Effects modifiers like age and gender controlled by stratification and pvalue of≤0.05 was taken as statistically significant.

Results: In this study there were 289 patients who underwent CABG. The average
age of patients was 52.27±9.078 years. Males were 200 (69%) and 89 (31%)
were female patients. 114 (39.44%) were within 51-60 years of age. During
follow up atrial fibrillation was reported in 44 (15.2%) cases in which 42 were
male and 02 were female patients. Frequency of atrial fibrillation was found 24
(54.54%) in patients of age group 61-65 years.

Conclusion: The frequency of AF following CABG was higher in male patients and
it increases with age
