Chronic remote ischemic conditioning for cardiovascular protection.

New treatments are needed to prevent adverse left ventricular remodelling following acute myocardial infarction (AMI), in order to prevent heart failure and improve clinical outcomes following AMI. Remote ischemic conditioning (RIC) using transient limb ischemia and reperfusion has been reported to reduce myocardial infarct (MI) size in AMI patients treated by primary percutaneous coronary intervention, and whether it can improve clinical outcomes is currently being investigated. Interestingly, repeated daily episode of limb RIC (termed 'chronic remote ischemic conditioning', or CRIC) has been shown in experimental and clinical studies to confer beneficial effects on post-AMI cardiac remodelling and chronic heart failure. In addition, the beneficial effects of CRIC extend to vascular function, peripheral arterial disease and stroke. In this review article, we focus on the therapeutic potential of CRIC as a strategy for cardiovascular protection and for improving clinical outcomes in patients with cardiovascular disease.
