摘要
The etiology of vasoplegic syndrome （VS） is not completely elucidated and the clinical im- portance remains speculative. Methods Twenty-four patients who underwent coronary artery bypass grafting and developed VS were compared with 48 control patients without VS in a 2：1 case control study. Cases and controls were matched by gender, age （ ± 5 years old） and operation date （ ±1 week）. Results The inde- pendent predictors of VS were lower ejection fraction （OR 10.75, 95% CI 2.93-39.44, when LVEF 〈 0.45） and diuretic use （OR 8.98, 95% CI 2.59-31.10） in logistic regression analysis. Conclusion lower ejection fraction （ 〈 0.45） and diuretic use are independent risk factors for VS occurrence.
