Overview
Brief Summary
Contrast-induced acute kidney injury (CI-AKI) is a significant iatrogenic complication of contrast media use associated with prolonged hospitalization, cardiovascular events, persistent kidney damage and increased risk of all-cause mortality. When remote ischemic preconditioning is applied before percutaneous coronary intervention (PCI), the kidneys can be protected against ischemia-reperfusion injury and subsequently CI-AKI. In this randomised controlled trial, diabetic nephropathy patients undergoing PCI as part of their assessment and treatment of cardiovascular disease are randomized to receive RIPC or control sham preconditioning.
Detailed Description
Contrast-induced acute kidney injury (CI-AKI) is a significant iatrogenic complication of contrast media use associated with prolonged hospitalization, cardiovascular events, persistent kidney damage and increased risk of all-cause mortality. Diabetes with pre-existing renal disease can increase the risk of CI-AKI. Remote ischemic preconditioning (RIPC) is a non-pharmacological strategy inducing transient episodes of ischemia by the occlusion of blood flow in non-target tissue such as a limb, before a subsequent prolonged ischemia-reperfusion injury occurs in a more distant organ. These brief, repeated ischemic episodes in the limb can confer a protection at more remote sites such as the heart, brain, lung, kidney, intestine or skeletal muscle. In a recent pilot study, using RIPC prior to coronary angiography in high risk patients with moderate chronic kidney disease, the authors found that RIPC significantly reduced the incidence of CI-AKI (Er et al Circulation. 2012;126(3),296). We hypothesized that RIPC would be protective as an adjunctive therapy in reducing the incidence of CI-AKI in diabetics with pre-existing CKD. This prospective study was performed to evaluate the efficacy of RIPC for the prevention of CI-AKI among diabetic nephropathy patients undergoing percutaneous coronary intervention.
