OBJECTIVE
In recent years, epicardial fat tissue (EFT) has been found to be strongly associated with the development of atrial fibrillation (AF). It was also reported to be a predictor of cardiac arrhythmias in different clinical situations. However, in the current literature, the role of EFT thickness in the development of AF in patients with non-ST-segment elevation myocardial infarction (NSTEMI) has not been studied. In this study, we aimed to investigate the relationship between EFT thickness and the development of new-onset AF in patients with NSTEMI during in-hospital follow-up.

METHODS
We enrolled 493 consecutive patients who were diagnosed NSTEMI in this study. During in-hospital follow-up, 68 patients developed AF, and the remaining 425 patients were determined as the control group. The thrombolysis in myocardial infarction (TIMI) risk score for NSTEMI was calculated. All clinical, echocardiographic, and laboratory parameters were compared between the 2 groups.

RESULTS
EFT thickness was higher in the AF group than in the controls (p<0.001). The TIMI risk scores were higher in the AF group (p<0.001). Logistic regression analysis demonstrated that EFT was an independent determinant for the development of AF (odds ratio 3.521, 95% confidence interval 1.616-6.314, p<0.001).

CONCLUSION
Incident AF was observed more frequently in patients with NSTEMI and higher EFT thickness. EFT was an important determinant of AF in patients with NSTEMI.
