Diastolic versus systolic dysfunction in patients with chronic liver disease ­ a single center study in South-South, Nigeria

ABSTRACT

Objectives: The term cirrhotic cardiomyopathy (CCM) has been used to describe the constellation of cardiovascular abnormalities including diastolic and systolic dysfunctions in patients with chronic liver disease (CLD). CCM contributes to morbidity and mortality associated with CLD. The aim of the study was to evaluate the left atrial and ventricular geometry, systolic and diastolic functions in patients with CLD. Material and Methods: This was a cross-sectional analytical study that involved 80 patients with CLD seen at University of Calabar Teaching Hospital, Calabar, Nigeria, and 80 apparently healthy controls matched for age/ gender. The participants were interviewed, examined and had resting transthoracic echocardiography. The data were analyzed using IBM SPSS version 20.0. Results: A total of 160 subjects were recruited into the study with a male to female ratio of 2.81. There was no difference in the mean age of cases and controls (P = 0.115). Systolic function of the left ventricle was similar in the two arms. However, left ventricular diastolic dysfunction, left atrial enlargement, and increased left ventricular mass index (LVMI) were more prevalent among the patients with CLD compared to controls (P < 0.05). Conclusion: The study demonstrated increased left atrial diameter, increased LVMI associated with diastolic dysfunction, and preserved systolic function at rest among CLD patients.
