Targeting long-chain acylcarnitine accumulation to protect cardiac mitochondrial homeostasis after complete revascularization.

ABSTRACT: Approximately 20% of acute myocardial infarction (AMI) patients with multivessel disease experience adverse outcomes after complete revascularization. We aim to investigate the underlying metabolic mechanism of ischemia-reperfusion injury responsible for abnormal hemodynamic stresses in high-risk patients undergoing complete revascularization. Elevated preoperative serum levels of long-chain acylcarnitine (LCAC) 16:1 are associated with an increased risk of poor prognosis following complete revascularization. Multi-omics analyses reveal that reperfusion injury activates fatty acid degradation, and carnitine palmitoyltransferase 1A (CPT1A) is identified as a key regulator of LCACs in the interaction network in porcine models. In the early stages of reperfusion injury in non-culprit lesions,
