Prevalence of Cardiac Dysfunction in Cirrhosis and Its Relation With Meld Score

Abstract

Background: Cardiac structural and functional abnormalities have been described in patients of liver cirrhosis. The constellation of these abnormalities is termed as cirrhotic cardiomyopathy (CCM) and its prevalence remains unknown, mostly because the disease is latent and shows itself when the patient is subjected to stress. This study was designed to evaluate the prevalence of cardiac dysfunction in patients of liver cirrhosis and to analyze its relation with model for end-stage liver disease (MELD) score. Methods: Hundred patients of liver cirrhosis were enrolled for the study and divided into 3 groups according to MELD score: ≤9, 10-19, and ≥20. All study participants underwent detailed cardiac assessment with Doppler echocardiography. Prevalence of cardiac dysfunction and its relation with MELD score was determined. Results: Prevalence of CCM and diastolic dysfunction (DD) was 48% and 30%, respectively. A total of 82%, 59%, and 50% patients had prolonged corrected QT interval (QTc), isovolumic relaxation time (IVRT), and deceleration time (DT), respectively. Prevalence of CCM, DD and prolonged QTc, IVRT, and DT had significant correlation with MELD score ( P < .05). Conclusion: Patients with cirrhosis had impaired cardiac function, mainly present as CCM and DD, and the extent of dysfunction was correlated with the MELD score. Hence, MELD scoring system can be used to predict risk of occurrence of cardiac dysfunction in cirrhosis.
