About

Cirrhotic cardiomyopathy is seen as a blunted contractile responsiveness to stress, and/or altered diastolic relaxation with electrophysiological abnormalities, in absence of known cardiac disease. Left ventricular diastolic dysfunction (LVDD) is associated with risk of hepatorenal syndrome (HRS) , septic shock. , heart failure in the perioperative period following liver transplantation, and after trans-jugular intrahepatic portosystemic shunt (TIPS) insertion . The echocardiographic E/e' ratio is a predictor of survival in LVDD, with multiple studies, including prospective data from our Centre. The inability of the heart to cope with stress or sepsis induced circulatory failure is a key concept of the increased mortality risk due to LVDD. In view of the metabolic syndrome and diabetes epidemic and an increasing number of patients being diagnosed with non-alcoholic fatty liver disease, there is increased risk of developing cardiac dysfunction due to multiple comorbidities including coronary artery disease, hypertensive heart disease, cirrhotic cardiomyopathy, which are contributors to overall cardiovascular risk of mortality.

Full description

Nonalcoholic fatty liver disease (NAFLD) and heart failure (HF) are obesity-related conditions with high cardiovascular mortality. Many new studies have linked NAFLD to changes in myocardial energy metabolism, and to echocardiographic measurements of cardiac dysfunction especially heart failure with preserved ejection fraction. Cardiac dysfunction in NAFLD is related to the release of inflammatory cytokines among those with steatohepatitis (NASH). However composite models looking at coronary artery disease, systolic and diastolic heart failure and outcomes in patients with NAFLD are limited, and the few preliminary analyses of this relationship using histologically-defined NASH or lean NAFLD remain unclear.

In this project the investigators will screen patients with a diagnosis of 'non-alcoholic fatty liver disease' for presence of coronary artery disease, arrhythmias, cirrhotic cardiomyopathy and develop a model for cardiac dysfunction in such patients.

Trial design

150 participants in 1 patient group

MASLD

Description:

Non invasive tests like APRI, FIB-4, , FAST scan and VCTE in the form of Fibroscan will be done and recorded. Liver biopsy would be done as per the clinical indication. Diagnosis of NAFLD will be based on history, physical examination, laboratory investigations, upper gastrointestinal endoscopy, imaging studies (ultrasonography and Doppler of spleno portal venous axis, VCTE) and liver biopsy where available.

Treatment:

Diagnostic Test: Echocardiographic assessment
