PROMISS: Simvastatin Prevents the Contrast Induced Acute Renal Failure in Patients With Renal Insufficiency Undergoing Coronary Angiography

Seoul National University Hospital320 enrolled

Overview

The contrast induced kidney toxicity has been known to affect the mortality and morbidity in the patients undergoing coronary angiography. But the mechanism and therapeutic strategy for it is not well known. Nowadays, it is reported that the N-acetylcysteine may have preventive effects for contrast induced kidney toxicity with its antioxidant effects.The statins have been reported to have many other effects other than the lipid lowering effect-including antioxidant effect, so we hypothesized that the antioxidant effect of simvastatin may prevent the contrast induced kidney toxicity.

The simvastatin may prevent the contrast agent induced acute renal failure in the patients with underlying renal insufficiency who is undergoing the coronary angiography. The effect may derive from the antioxidant function of simvastatin.

Outcomes

Primary Outcomes

The mean peak increase of serum creatinine concentration during day1 and day2.

Secondary Outcomes

Incidence of contrast induced nephropathy, defined as either a relative increase in serum creatinine from baseline of >=25% or an absolute increase of >=0.5mg/dL(44.2µmol/L) during days 1 and 2.

Proportion of patients exhibiting an increase in serum creatinine of >=0.5mg/dL(44.2µmol/L), the proportion with a >=1.0 mg/dL(88.4µmol/L) increase in serum creatinine, and the mean peak increase in serum creatinine.
