Silymarin for the Prevention of Atrial Fibrillation After Cardiac Surgery

December 3, 2024 updated by: Mihaela Preveden, University of Novi Sad

The Effect of Silymarin on the Prevention of Atrial Fibrillation After Coronary Artery Bypass Graft Surgery

The study is a prospective, randomized, controlled trial to assess the effects of silymarin on the occurrence of postoperative atrial fibrillation after coronary artery bypass graft surgery.

Detailed Description

Postoperative atrial fibrillation (POAF) is a frequent complication after coronary artery bypass graft (CABG) surgery and is associated with increased mortality. So far, the effects of various drugs and supplements on the occurrence of postoperative atrial fibrillation (POAF) have been studied, but no one has looked into the effect of silymarin on the occurrence of POAF.

The study is designed as a prospective, randomized, controlled trial to assess the effects of silymarin on the occurrence of postoperative atrial fibrillation after CABG surgery. A total of 160 patients of both sexes scheduled for elective CABG surgery using cardiopulmonary bypass (CPB) will be included. They will be randomized into two groups (experimental and control) with 80 patients each. Subjects in the experimental group will receive 400 mg of silymarin three days preoperatively, while subjects in the control group will receive standard therapy.

The occurrence of POAF after CABG surgery will be the primary outcome, which will be defined as any dysrhythmia that represents the ECG characteristics of atrial fibrillation lasting at least 30 s on a rhythm strip or 12-lead ECG. Secondary outcomes will include postoperative values of inflammation markers, length of stay in the ICU, length of hospitalization, and occurrence of postoperative complications (pericardial effusion, stroke, in-hospital death).

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Experimental group
Silymarin 400 mg daily, orally, divided into two doses, for three days preoperatively
Subjects of the experimental group will receive silymarin (capsules containing 100 mg silymarin, expressed as silibinin) three days preoperatively. The dose they receive will be the recommended dose for the registered indications (400 mg daily, orally, divided into two doses).
No Intervention: Control group
Optimal standard therapy
