Speckle tracking echocardiography enables the detection of subclinical left ventricular dysfunction at rest in many heart diseases and potentially in severe liver diseases. It could also possibly serve as a predictor for survival. In this study, 117 patients evaluated for liver transplantation in a single center between May 2010 and April 2016 with normal left ventricular ejection fraction were included according to clinical characteristics of their liver disease: (1) compensated (n= 29), (2) clinically significant portal hypertension (n= 49), and (3) decompensated (n= 39). Standard echocardiography and speckle tracking echocardiography were performed at rest and during dobutamine stress. Follow-up amounted to three years to evaluate survival and major cardiac events. Altogether 67% (78/117) of the patients were transplanted and 32% (31/96 patients) died during the three-year follow-up period. Global longitudinal strain (GLS) at rest was significantly increased (became more negative) with the severity of liver disease (p< 0.001), but reached comparable values in all groups during peak stress. Low (less negative) GLS values at rest (male: >-17/female: >-18%) could predict patient survival in a multivariate Cox regression analysis (p= 0.002). GLS proved valuable in identifying transplant candidates with latent systolic dysfunction.
