Abstract
Objective Myocardial injury after non-cardiac surgery (MINS) is strongly associated with mortality, but few studies assessed treatment strategies. This study aimed to identify whether evaluation by cardiologists could reduce mortality in MINS patients.
Methods From a single-centre retrospective cohort, we enrolled a total of 5633 adult patients diagnosed with MINS between January 2010 and June 2019. The patients were divided into two groups based on evaluation by cardiologist, which was defined as a cardiology consultation or transfer to the cardiology department. For the outcome, 30-day mortality was compared in crude and propensity-score matched populations.
Results Of a total of 5633 patients, 2120 (37.6%) were evaluated by cardiologists and 3513 (62.4%) were not. Mortality during the first 30 days after surgery was significantly lower in MINS patients who were evaluated by cardiologists compared with those who were not (5.8% vs 8.3%; HR, 0.64; 95% CI 0.51 to 0.80; p<0.001 for all-cause mortality and 1.6% vs 2.0; HR 0.62; 95% CI 0.40 to 0.96; p=0.03 for cardiovascular mortality). The propensity score matched analysis showed similar results (5.6% vs 8.6%; HR 0.64; 95% CI 0.50 to 0.81; p<0.001 for all-cause mortality and 1.3% vs 2.2%; HR 0.58; 95% CI 0.35 to 0.95; p=0.03 for cardiovascular mortality).
Conclusions Cardiologist evaluation was associated with lower mortality in patients diagnosed with MINS. Further studies are needed to identify effective treatment strategies for MINS.
