Abstract Background Cirrhosis is associated with chronic cardiovascular dysfunction termed cirrhotic cardiomyopathy (CCM), characterized by myocardial hypertrophy and diastolic dysfunction. Detecting early cardiac changes is crucial, especially in patients undergoing liver transplantation. Objective: This study aims to evaluate left ventricular systolic function in cirrhotic patients undergoing liver transplantation using speckle-tracking echocardiography. Methods A prospective observational study was conducted involving 54 cirrhotic patients who underwent liver transplantation, along with 28 age- and sex-matched healthy controls. Echocardiography, including conventional and two-dimensional speckle tracking echocardiography (2D-STE), was performed at baseline and one-month post-transplantation. Results The mean age in the cirrhotic group was 52.2 ± 12.7 years, with no significant difference compared to the control group. Viral hepatitis was the predominant etiology of cirrhosis (68.6%). Conventional echocardiography did not reveal significant differences between groups in LV ejection fraction [62% (56–69) vs. 59% (56–62); p = 0.830]. However, in cirrhotic patients, 2D-STE demonstrated significantly lower LV global longitudinal strain (LV-GLS) [17.5 (15.5–19.1) vs 19.0 (18.0–19.7), p = 0.006]. Post-transplantation, conventional echocardiography indices remained unchanged, while 2D-STE showed remarkable improvement in LV function, with increased LV-GLS compared to pre-transplantation value. Conclusions 2D-STE is a valuable tool for detecting and monitoring left ventricular systolic dysfunction in liver cirrhosis patients, particularly following transplantation. While conventional echocardiography may not detect subtle changes, 2D-STE reveals improvements in LV function post-transplantation, emphasizing its role in assessing cirrhotic cardiomyopathy.
