ConclusionsWe believe we have demonstrated that in patientsreferred for elective percutaneous coronary intervention, remote ischemic preconditioning doesnot provide statistically significant benefits indecreasing the incidence of contrast-inducednephropathy. Cystatin C is considered an earlymarker of kidney injury, but measuring it 24h after percutaneous coronary intervention does notdetect all cases of contrast-induced nephropathy.Remote ischemic preconditioning before percutaneous coronary intervention does not influence1-year follow-up outcome
