Abstract:
Multimers of von Willebrand factor (VWF) play a critical role in various processes inducing morbidity and mortality in cardiovascular risk patients. With the ability to reduce VWF multimers, N-acetylcysteine (NAC) could reduce mortality in patients undergoing coronary catheterization or cardiac surgery. However, its impact in perioperative period has never been studied so far in regard of its potential cardiovascular benefits. Then, four databases were searched for randomized controlled trials that compared in-hospital mortality between an experimental group, with NAC, and a control group without NAC, in patients undergoing coronary catheterization or cardiac surgery. The primary efficacy outcome was in-hospital mortality. Secondary outcomes were the occurrence of thrombotic events, major cardiovascular events, myocardial infarction, and contrast induced nephropathy. The safety outcome was occurrence of hemorrhagic events. Nineteen studies totaling 3718 patients were included. Pooled analysis demonstrated a reduction of in-hospital mortality associated with NAC: Odds Ratio (OR), 0.60; 95% CI, 0.39−0.92; P=0.02. The occurrence of secondary outcomes was not significantly reduced with NAC except for contrast-induced nephropathy. No difference was reported for hemorrhagic events. Subgroup analyses revealed a life-saving effect of NAC in a dose-dependent manner with reduction of in-hospital mortality for the NAC high-dose group, but not for the NAC standard-dose ( 〈 3500 mg) group. In conclusion, without being able to conclude on the nature of the mechanism involved, our review suggests a benefit of NAC in cardiovascular risk patients in perioperative period in terms of mortality and supports prospective confirmatory studies.
