Background: The concept of cirrhotic cardiomyopathy includes impaired cardiac contractility, decreased beta-adrenergic receptor function, abnormal beta-adrenergic postreceptor function, defective excitation-contraction coupling, and cardiac conduction abnormalities. This study was aimed to assess the cardiac structure and function in adult Nigerians with chronic liver disease (CLD). Methods: This was a cross-sectional descriptive study of consecutive patients with CLD without any known cardiac disease attending the Liver Clinic of the Medical Out-patient Department of the University College Hospital. Apparently, normal individuals with comparable age and sex distribution were recruited as controls. The subjects and controls underwent two-dimensional, M-mode and Doppler echocardiographic studies to determine the cardiac structure in relation to both systolic and diastolic cardiac functions. Results: A total of 46 subjects and 50 normal controls were recruited. There was no difference in the blood pressure parameters of the two groups. The septal wall thickness was statistically higher in control, but this difference was lost when adjusted for body mass index. On the other hand, the adjusted left atrial diameter and aortic root dimension were statistically larger in the subjects than the controls. There was no difference in the left ventricular (LV) fractional shortening or ejection fraction, relative wall thickness, and deceleration time of the E-wave. Conclusions: We demonstrated an increase in cardiac index at rest in the subjects, but there was no significant difference in the LV diastolic or systolic dysfunction using traditional methods. Studies using newer modalities of the assessment of cardiac structure and function are needed in our environment.
