Abstract: Myocardial infarction (MI) caused by ischemia-reperfusion injury (IRI) is the leading risk factor for heart failure. The sodium-hydrogen exchange (NHE) inhibitor, cariporide, is the only cardioprotective drug to reach Phase 3 clinical trials, but it caused cerebrovascular side effects. There remain no clinically approved drugs that block cardiomyocyte cell death during acute IRI.
