PurposePatients with cirrhosis and concomitant coronary/valvular heart disease present a clinical dilemma. The therapeutic outcome of major cardiac surgery is significantly poorer in patients with cirrhosis compared with patients without cirrhosis. To address this, we aimed to identify associations between the severity of cirrhosis and post-cardiac surgical outcomes.MethodsA historical cohort analysis of patients undergoing cardiac surgery at the University of Alberta Hospital from January 2004 to December 2014 was used to identify and propensity score-match 60 patients with cirrhosis to 310 patients without cirrhosis. The relationships between cirrhosis and i) mortality, ii) postoperative complications, and iii) requirement of healthcare resources were evaluated.ResultsTen-year mortality was significantly higher in cirrhotic patients compared with propensity score-matched non-cirrhotic patients (40% vs 20%; relative risk [RR], 2.0; 95% confidence interval [CI], 1.3 to 2.9; P = 0.001). Cirrhotic patients had more complications (63% vs 48%; RR, 1.3; 95% CI, 1.05 to 1.7; P = 0.02), longer median [interquartile range (IQR)] intensive care unit stays (5 [3-11] vs 2 [1-4] days; P < 0.001), time on mechanical ventilation (median [IQR] 2 [1-5] vs 1 [0.5-1.2] days; P < 0.001) and more frequently required renal replacement therapy (15% vs 6%; RR, 2.5; 95% CI, 1.2 to 5.2; P = 0.02) postoperatively. After adjusting for other covariates, presence of cirrhosis (adjusted odds ratio, 2.2; 95% CI, 1.1 to 4.1) and intraoperative transfusion (adjusted odds ratio, 3.2; 95% CI, 1.6 to 6.3) were independently associated with increased mortality.ConclusionDespite having low median model for end-stage liver disease scores, this small series of cirrhotic patients undergoing cardiac surgery had significantly higher mortality rates and required more organ support postoperatively than propensity score-matched non-cirrhotic patients.
