Percutaneous coronary intervention (PCI) is a common procedure for treating coronary artery disease, but it carries a risk of periprocedural myocardial injury (PMI). This meta-analysis evaluated the efficacy of nicorandil, a hybrid compound with nitrate-like and potassium channel-opening properties, in preventing PMI during PCI. A comprehensive literature search identified 14 studies involving 1,762 patients, with 882 receiving nicorandil and 880 in the control group. The analysis revealed that nicorandil significantly reduced the incidence of PMI (RR: 0.73, 95% CI: 0.61-0.86) and major adverse cardiovascular events (MACE) (RR: 0.76, 95% CI: 0.58-0.99) compared to the control group. Nicorandil's cardioprotective effects are attributed to its ability to improve coronary blood flow, precondition the myocardium, and reduce oxidative stress and inflammation. These findings suggest that nicorandil could be a valuable adjunctive therapy during PCI, potentially improving patient outcomes. However, the study had limitations, including variations in drug administration methods and a lack of individual-level data for subgroup analysis. Future research should focus on optimizing dosing regimens and administration timing and comparing nicorandil's effectiveness with other cardioprotective agents.

Introduction: Contrast-induced nephropathy (CIN) is a potential complication associated with the administration of intravenous contrast agents. The objective of this study was to evaluate the effectiveness of remote ischemic preconditioning (RIPC) and two pharmacological interventions in preventing CIN.
Methods: Randomized controlled trials (RCTs) examining the efficacy of RIPC, nicorandil, and trimetazidine in treating CIN were searched within databases such as PubMed, Cochrane Library, Embase, and Web of Science.

Background: Myocardial ischemia-reperfusion injury (MI/RI) poses a significant challenge during coronary revascularization. This research investigated alterations in oxidative stress and ferroptosis, alongside the impact of nicorandil on these aspects, among patients undergoing acute ST-elevation myocardial infarction (STEMI) and receiving primary percutaneous coronary intervention (pPCI).
Methods: 121 patients with STEMI who were undergoing pPCI were included in the study, and we documented their thrombolysis in myocardial infarction (TIMI) blood flow grades before and after the procedure.

Nicorandil (NIC) is a well-known anti-anginal agent, which has been recommended as one of the second-line treatments for chronic stable angina as justified by the European guidelines. It shows an efficacy equivalent to that of classic anti-anginal agents. NIC has also been used clinically in various cardiovascular diseases such as variant or unstable angina and reperfusion-induced damage following coronary angioplasty or thrombolysis.

Background: Exosomes derived from bone marrow mesenchymal stem cells (MSC-exo) have been considered as a promising cell-free therapeutic strategy for ischemic heart disease. Cardioprotective drug pretreatment could be an effective approach to improve the efficacy of MSC-exo. Nicorandil has long been used in clinical practice for cardioprotection.
