Advanced stages of MASLD (fibrosis/MASH) causally contribute to heart failure with preserved ejection fraction (HFpEF) through mechanical impediments to hepatic blood flow, reducing right ventricular preload.

If you have advanced liver fibrosis, monitor for signs of heart failure (fatigue, shortness of breath) even if your heart structure looks normal. The stiffness of your liver can mechanically impede blood flow back to the heart, contributing to HFpEF. Managing liver inflammation may help cardiac preload.

ModerateSupportsMEDIUM confidence
In the more advanced fibrotic stages, MASLD may contribute to heart failure with preserved ejection fraction by reduced filling of the right ventricle, which may induce fatigue upon exertion... A putative mechanism in which MASLD per se might cause heart failure with preserved ejection fraction is through reducing the preload reserve.

Why this rating

Based on mechanistic models and observational studies; causality is suggested but not definitively proven in large RCTs.
