  Purpose

Remote ischemic preconditioning reduces the incidence of contrast-induced acute kidney injury in patients undergoing elective coronary angiography. This study was designed to acquire long-term data of initially randomized patients in the RenPro Trial.


Condition Intervention
Impaired Renal Function
Other: Ischemic preconditioning

Study Type: Observational
Study Design: Observational Model: Case Control
Time Perspective: Prospective
Official Title: Remote Preconditioning for Contrast-Induced Acute Kidney Injury: Long-Term Follow up (RenPro Longterm)

Further study details as provided by University of Cologne:

Primary Outcome Measures:
  • MACCE [ Time Frame: 1 Year ] [ Designated as safety issue: Yes ]

    Major Adverse Cardiac and Cerebrovascular Events (Combined primary endpoint):

    All-cause mortality, cardiovascular mortality, rehospitalization, stroke, myocardial infarction, hemodialysis



Secondary Outcome Measures:
  • Renal function [ Time Frame: 1 year ] [ Designated as safety issue: Yes ]
    changes of serum creatinine, eGFR, NGAL and cystatin C compared to baseline in both groups.


Estimated Enrollment: 81
Study Start Date: July 2012
Estimated Study Completion Date: January 2013
Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Subjects with impaired renal function
