Percutaneous coronary intervention is a revolutionary treatment for ischemic heart disease, but in-stent restenosis (ISR) remains a clinical challenge. Inflammation, smooth muscle proliferation, endothelial function impairment, and local thrombosis have been identified as the main mechanisms for ISR. Considering the multifactorial mechanisms of ISR, a novel therapeutic agent with multiple bioactivities is required. Ghrelin is a novel gut-brain peptide predominantly produced by the stomach, and has been shown to play a role in various cardiovascular activities, such as increasing myocardial contractility, improving cardiac output, and inhibiting ventricular remodeling, as well as attenuating cardiac ischemia-reperfusion injury. Recent studies have demonstrated that ghrelin effectively inhibits vascular inflammation and vascular smooth muscle cell proliferation, repairs endothelial cells, promotes vascular endothelial function, inhibits platelet aggregation, and exerts antithrombotic effects. These findings suggest that ghrelin may be an innovative therapeutic candidate for the prevention and treatment of ISR.
