APOA1 and myocardial infarction: Kalakech et al. suggested that ApoA1 may be involved in the protection conferred by RIC, based on data showing i.v. administration of ApoA1 prior to prolonged myocardial ischemia (MI, 40-min occlusion of coronary artery in rats) could mimic cardioprotection achieved by RIPreC (81).
