Abstract
Late allocation of organs for transplant impairs post-liver transplantation (LT) survival. Cardiac dysfunction, especially diastolic and autonomic dysfunction, is frequent and plays an important role in the prognosis of patients with cirrhosis. However, the role of myocardial contractility is unexplored, and its prognostic value is controversially discussed. This study analyses the role of myocardial contractility assessed by speckle tracking echocardiography in LT allocation. In total, 168 patients with cirrhosis (training cohort, 111; validation cohort [VC], 57) awaiting LT in 2 centers were included in this retrospective study. Also, 51 patients from the training and all patients from the VC were transplanted, 36 patients of the training and 38 of the VC were alive at the end of follow-up, and 21 nontransplanted patients died. Contractility of the left ventricle (LV) increased with severity of the Child-Pugh score. Interestingly, higher LV contractility in the training cohort patients, especially in those with Child-Pugh C, was an independent predictor of reduced transplant-free survival. In male patients, the effects on survival of increased left and right ventricular myocardial contractility were more pronounced. Notably, competing risk analysis demonstrated that increased contractility is associated with earlier LT, which could be confirmed in the VC. Importantly, LV myocardial contractility had no impact on survival of patients not receiving LT or on post-LT survival. In conclusion, this study demonstrates for the first time that increased myocardial contractility in decompensated patients identifies patients who require LT earlier, but without increased post-LT mortality.
