Vitamin B Supplementation for Patients Undergoing Cardiovascular Surgery

This study is a multicenter, randomized controlled, double-blind, placebo-controlled parallel trial designed to evaluate the effect of perioperative supplementation with Compound Vitamin B on patients undergoing cardiovascular surgery. A total of 1,000 patients aged 18-80 years who are scheduled to receive cardiovascular surgeries such as coronary artery bypass grafting (CABG) and valve replacement will be enrolled. They will be randomly assigned at a 1:1 ratio to either the experimental group (perioperative supplementation with Compound Vitamin B tablets, once daily from 3 days before surgery to 6 months after surgery) or the control group (oral placebo), with both groups receiving standardized perioperative treatment.
