Abstract

Advanced liver disease is a risk factor for cardiac surgery. However, liver dysfunction is not included in cardiac risk assessment models. We sought to identify trends in utilization, complications, and outcomes of patients with cirrhosis who underwent coronary artery bypass graft surgery (CABG). Using the National Inpatient Sample database, we identified patients with cirrhosis who underwent CABG from 2002 to 2014. Propensity-score matching was used to identify differences in in-hospital mortality and postoperative complications in cirrhosis and noncirrhosis patients. We identified a total of 698,799 CABG admissions of which 2,231 (0.3%) had cirrhosis (mean age 63.6 ± 9.6 years, 74% men, 63% white, mean Charlson co-morbidity index 3.3 ± 1.8). Cardiopulmonary bypass was used in 71% of patients. Mean length of stay was 13.7 ± 11.4 days and hospitalization cost $67,744.6 ± 58,320.4. One or more complications occurred in 44% of cases. After propensity-score matching, patients with cirrhosis had a higher rate of complications (43.9% vs 38.93%; p < 0.001) and in-hospital mortality (7.2% vs 4.07%; p < 0.001) than noncirrhosis patients. On multivariate analysis, cirrhosis and ascites were associated with increased in-hospital mortality (odds ratio 2.87; 95% confidence intervals 2.37 to 3.48) and postoperative complications (odds ratio 5.11; 95% confidence intervals 3.88 to 6.72). In conclusion, patients with cirrhosis constitute a small portion of patients who underwent CABG in the United States but have a higher rate of complications and in-hospital mortality compared with noncirrhosis patients. In-hospital mortality remains high for this subset of patients but has decreased in recent years.
