Abstract
This study is aimed at evaluating the effect of empagliflozin in preventing atrial fibrillation after coronary artery bypass grafting (CABG). Eighty-two patients who fulfilled the inclusion criteria were allocated to the empagliflozin group (n = 43) or placebo group (n = 39). In two groups, patients received empagliflozin or placebo tablets 3 days before surgery and on the first three postoperative days (for 6 days) in addition to the standard regimen during hospitalization. During the first 3 days after surgery, types of arrhythmias after cardiac surgery, including supraventricular arrhythmias, especially postoperative atrial fibrillation (POAF), ventricular arrhythmias, and heart blocks, were assessed by electrocardiogram monitoring. C-reactive protein (CRP) levels were evaluated pre-operatively and postoperative on the third day. The incidence of POAF in the treatment group was lower compared to the control group; however, this reduction was statistically non-significant (p = 0.09). The frequency of ventricular tachycardia was reduced significantly in the treatment group versus patients in the control (p = 0.02). Also, a significant reduction in the frequency of premature ventricular contractions (PVCs) was seen in the treatment group in comparison with the control group (p = 0.001). After the intervention, CRP levels were significantly less in the empagliflozin group compared to the control group in the third postoperative day (p = 0.04). The prophylactic use of empagliflozin effectively reduced the incidence of ventricular arrhythmia in patients undergoing CABG surgery.
