Abstract

Background & Aims: Non-ischaemic cardiomyopathy (NIC) is an early complication of liver transplantation (LT). Our aims were to define the prevalence, associated clinical factors, and prognosis of this condition. Methods: A retrospective study was performed on patients undergoing LT at our institution from January 2005 to December 2012. Patients who developed NIC were identified. Data collected included demographic and clinical data. Results: A total 1460 transplants were performed in this period and seventeen patients developed NIC. Pretransplant median QTc interval was 459 (range, 405-530), and median E/A ratio was 1 (range, 0.71-1.67). Fourteen patients (82%) were severely malnourished and required nutritional support. Thirteen patients (76%) had renal insufficiency. Median time to onset was 2 days post-transplant (range, 0-20). Echocardiograms showed global left ventricular hypokinesis and a decrease in ejection fraction (EF) from a median of 65% (range, 50-81) pretransplant to a median of 21% (range, 15-32). Median raw model for end-stage liver disease (MELD) score was 29 in patients with NIC vs. 18 in patients without cardiomyopathy (P = 0.01). There was no significant difference between recipients with NIC vs. recipients without cardiomyopathy regarding donor age, donor risk index, and cold and warm ischaemia time. Recovery of cardiac function occurred in 16 patients, with a median EF of 44% (range, 25-65%) at the time of discharge. The last echocardiogram available showed a median EF of 59% (range, 49-73%). One-year survival of NIC patients was 94.1%. Conclusion: Non-ischaemic cardiomyopathy is a rare complication after LT. Patients with NIC are critically ill, with high MELD score, and severe malnutrition.
