Abstract
Cardiac dysfunction in cirrhosis of liver remains dormant due to hyperdynamic
circulatory state even with the severe stage of cirrhosis. This in actuality is
worsening of the cardiac functions. The decline in diastolic functions, inotropic
and chronotropic functions and cardiac hypertrophy all occur simultaneously in
the setting of an absent organic cardiac disease. The Cirrhotic cardiomyopathy
has pertinent indings in its loop comprising of impaired contractile reaction to
stress stimuli and electrophysiological abnormalities along with prolonged QT
interval. The disruption in β-adrenergic receptor signalling, altered composition
of cardiomyocyte membrane lipids plus biophysical properties, ion channel
defects and enhanced cardiodepressant factors attributed to hormones are
the pathogenic assailants. The hindrance to diagnose cirrhotic cardiomyopathy
mainly lies in unavailability of a stark speciic diagnostic test nevertheless; an
echocardiogram is favourably used to follow deteriorating diastolic functions
and the E/e′ ratio thus giving insight to the progression of disease. The severity
of cirrhosis is linked in parallel with ensuing cirrhotic cardiomyopathy which
substantially impairs arterial blood volume. So, in case of any hemodynamic
stress, a heart bearing cirrhotic cardiomyopathy retorts with diminished cardiac
response which may cause renal hypoperfusion leading to renal failure. The
management is mainly symptomatic where only the liver transplantation could
play an imperative role in correction of the cardiac functions.

cardiac involvement in the form of Cirrhotic Cardiomyopathy
(CCM) has recently gained attention as the commonest cause of post
liver transplant mortality [3].
Cardiac dysfunction was established in cirrhosis of liver half
a century ago when cardiovascular changes like hyperdynamic
circulation, high cardiac output, reduced peripheral vascular
resistance and reduced blood pressure were described [4,5].
Consequent pathological evidence of cardiac dysfunction in cirrhosis
of liver was cardiac hypertrophy, edema of cardiomyocyte without
valvular heart disease, coronary artery disease and hypertension
[6]. Initially, it was believed that the cardiac dysfunction is directly
consequent to alcohol toxicity and was termed as latent alcoholic
cardiomyopathy [7]. he decreased hemodynamic retort to either
of the physiologic (exercise) or pharmacologic strain even with an
elevated basal cardiac output which was witnessed in a few trials
on human and animal models of non-alcoholic cirrhosis [8,9]. his
review spotlights on deinition, pathophysiology, clinical signiicance,
diagnosis and management of CCM.
Deinition of CCM
CCM is deined as impaired cardiac functions without any organic
cardiac disorder pertaining to diminished cardiac contractility when
stimulated (physiological / pharmacological) and adapted relaxation

Introduction
Cirrhosis is a chronic state of liver caused by various aetiologies
characterized by altered parenchyma and distorted hepatic vascular
architecture consequent to chronic tissue ibrosis and regenerative
nodules [1,2]. Globally, cirrhosis has become an emergent cause
of mortality. Apart from the known complications of cirrhosis like
