The predictors of post-transplant coronary events among liver transplant recipients

The predictors of post-transplant coronary events among liver transplant recipients

Hepatology International 10(6): 974-982

Cardiac morbidities can occur during the peri- and post-liver transplant (LT) period, affecting the long-term survival. The purpose of this study was to identify the potential factors that predict a coronary event post-transplantation. Medical records of patients who underwent liver transplantation at Johns Hopkins Hospital between 2009 and 2013 were retrospectively reviewed. We looked at pre-liver transplant cardiac risk factors and the diagnostic tests utilized for coronary artery disease screening. Patients with and without post-liver transplant coronary events were compared. There were a total of 146 patients with a mean age at LT of 55.3 years. The prevalence of hypertension, tobacco use and diabetes within the patient population was 61.6 % (n = 90), 39 % (n = 57) and 37.6 % (n = 55), respectively. There were 29 deaths and 30 coronary events over a median follow-up period of 1.75 years. Age at the time of liver transplant was predictive of coronary event (OR 1.11, CI 1.01-1.20). The 1-year survival in patients with a coronary event was 47 versus 94 % in patients without a coronary event. The combined use of a dobutamine stress echocardiogram and coronary artery calcium score predicted a coronary event with a sensitivity of 62.5 % and specificity of 66.7 %. In conclusion, LT recipients with cardiac events had limited survival as compared to the cohort without coronary events. Identification of such patients with noninvasive screening may provide a practical alternative to an invasive cardiac workup. Further improvement in screening strategies may minimize the liver transplant cardiac morbidity.
