Study of amphipathic metabolites in cardiac pathophysiology: Insights gained from long‐chain acylcarnitines and calcium handling.

This article discusses the role of long-chain acylcarnitines (LCACs) in cardiac pathophysiology. Metabolomics studies have identified associations between LCACs and cardiovascular diseases such as heart failure and cardiac arrhythmias. The article focuses on the effects of LCACs on the ryanodine receptor (RyR2), a calcium release channel in cardiomyocytes. The study found that LCACs promote spontaneous calcium release and intracellular calcium accumulation, potentially through increased cytosolic calcium levels. The article also highlights the importance of considering methodological limitations and membrane perturbation effects when studying LCACs. The findings have implications for future research on LCACs and their potential as therapeutic targets for cardiovascular diseases. [Extracted from the article]
