Summary

This is a prospective randomised trial investigating the effect of a preemptive administration of levosimendan on postoperative cardiac NT-proBNP concentrations.

Description

Major cardiovascular complications occur in about 3 % of all patients undergoing noncardiac surgery and are even higher in patients with increased preoperative risk factors. N-terminal pro brain natriuretic peptide (NT-proBNP) increases in over two third of patients undergoing surgery and is a strong predictor for perioperative myocardial complications. Levosimendan is a positive inotropic Ca2+ sensitizer and significantly reduces postoperative BNP concentration in cardiac surgery. The evidence in the non-cardiac surgery setting, however, is weak. Therefore, we will test our primary hypothesis that the perioperative administration of levosimendan significantly will reduce postoperative NT-proBNP concentrations in patients undergoing moderate- to high-risk non-cardiac surgery. We will also test the secondary hypotheses that levosimendan will reduce postoperative maximum troponin T (maxTnT) concentration, the incidence of myocardial injury after noncardiac surgery (MINS), myocardial infarction and death within 30 days and one year after surgery.
