  Purpose

The prevention of contrast-mediated nephropathy (CMN), which accounts for considerable morbidity and mortality, remains a vexing problem. Contrast induced renal vasoconstriction is believed to play a pivotal role in the CMN mechanism. The aim of this study is to examine the efficacy of the prostacyclin analogue iloprost (dose 1ng/kg/min) in preventing CMN in high-risk patients undergoing a coronary procedure.

Primary Outcome Measures:
  • CMN is defined as an absolute increase of serum creatinine concentration of at least 0.5 mg/dl [ Time Frame: 2-5 days after the procedure ]
  • or CMN is defined as a relative rise of at least 25% from baseline on the follow-up [ Time Frame: blood sample drawn at 2-5 days after the procedure ]

Secondary Outcome Measures:
  • Differences in the progression of serum creatinine concentrations and creatinine clearance among the study groups [ Time Frame: 2-5 days after the procedure ]
