Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a prospective, double-blind, sham-controlled, multicenter, randomized clinical trial is to study the effects of remote ischemic preconditioning on contrast-associated acute kidney injury, functional capacity, and major adverse kidney events in in patients with congestive heart failure undergoing cardiac catheterization and/or percutaneous coronary intervention.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The RICH Trial is a prospective, multicenter, randomized clinical trial to determine the effect of remote ischemic preconditioning on contrast associated acute kidney injury, and to characterize the effect of remote ischemic preconditioning on brain natriuretic peptide, functional capacity at one month, and major adverse kidney events (persistent renal dysfunction, renal replacement therapy, and death) at three months in patients with congestive heart failure with reduced left ventricular ejection fraction undergoing coronary angiography and/or percutaneous coronary intervention.
