This document provides a summary of various studies related to cardiovascular diseases. The first study explores the potential of targeting lipolysis in white adipose tissue (WAT) to improve diastolic dysfunction in heart failure with preserved ejection fraction (HFpEF). The second study investigates a new mouse model for arrhythmogenic cardiomyopathy caused by filamin C haploinsufficiency. The third study examines the role of miR-721 in autoimmune myocarditis and its potential as a therapeutic target. These studies contribute to our understanding of the mechanisms and potential treatments for these cardiovascular conditions. [Extracted from the article]
