A review regarding the article 'Electrocardiographic abnormalities in patients with metabolic dysfunction-associated...

Metabolic-dysfunction-associated Steatotic liver disease (MASLD) is a high-risk condition for both liver fibrosis and cardiovascular disease (CVD). Therefore, therapeutic strategies to prevent both liver fibrosis and atherosclerotic CVD are required for the treatment of MASLD. Metabolic dysfunction-associated steatohepatitis (MASH) is the more severe form of MASLD, is defined histologically by the presence of lobular inflammation and hepatocyte ballooning and is associated with a greater risk of fibrosis progression. While CVD is the leading cause of mortality in patients with MASLD, those with more severe liver fibrosis are at increased risk of liver-related mortality, with the risk increasing exponentially with fibrosis stage. MASH has been found in 63% of patients with MASLD undergoing liver biopsy in an Asian multi-center cohort. Multiple complex pathways are involved in the association between MASLD and CVD. The visceral accumulation of fat around the liver and other organs, including the pericardium, leads to the release of fat-derived metabolites with the activation of several inflammatory pathways Cardiac rhythm abnormalities are prevalent in MASLD, such as prolongation of the QT interval, ventricular arrhythmias, and atrial fibrillation. Therapeutic interventions that improve cardiometabolic risk factors may be beneficial for an improvement in MASLD. The effects of such therapeutic interventions on lipid, lipoprotein and apoprotein accumulation in the liver and on hepatic steatosis and fibrosis still remain unelucidated. Which lipid factor is crucial for developing MASLD also remains largely unknown.
