Factors Predicting Cardiac Dysfunction in Patients with Liver Cirrhosis.

BACKGROUND Left ventricular diastolic dysfunction (LVDD) is the earliest cardiac dysfunction noted in patients with liver cirrhosis, which increases the morbidity and mortality in such patients. There are sparse studies from India evaluating the predictive factors of LVDD in patients with cirrhosis. Hence we undertook this prospective study with an aim to evaluate the factors predicting the development of LVDD in liver cirrhosis. METHODS 104 patients with cirrhosis were enrolled in this prospective study. A detailed cardiac evaluation was done by 2 D echocardiography with tissue Doppler imaging by an experienced senior cardiologist. The severity of liver disease was defined by Model For End-Stage Liver Disease (MELD) and Child-Pugh score. RESULTS The prevalence of LVDD was 46% in our study. Multivariate logistic regression analysis revealed that serum albumin, MELD score, and presence of ascites (OR = 0.1, 95%CI 0.03-0.3, p < 0.001; Or = 1.12, 95%CI 1.03-1.22, p < 0.001; OR = 4.19, 95%CI 1.38-12.65, p < 0.01, respectively) were independent predictors of LVDD in patients with cirrhosis. Diastolic dysfunction was unrelated to age, sex, and etiology of cirrhosis. The patients with cirrhosis and LVDD had significantly higher child Pugh score, MELD score, and lower serum albumin than patients without LVDD. The echocardiographic parameters like E/e' ratio, Deceleration time (DT), and Left atrial volume index (LAVI) were significantly different in cirrhotic patients with higher MELD and child Pugh score than lower. CONCLUSION The present study showed a significant correlation of diastolic dysfunction with the severity of the liver disease. Low serum albumin, high MELD score, and presence of ascites significantly predict the development of LVDD in patients with cirrhosis.
