Primary efficacy endpoint is change in renal function, evaluated by 51Cr-EDTA clearance between 24 hours pre open-heart surgery and 48 hours post open-heart surgery. Sample size is 20, ten in each group.

Prophylactic Effect of Nifedipine on Further Decline in Renal Function in Patients Undergoing Open-Heart Surgery
Postoperative Renal Function After Open-Heart Surgery in Patients With Impaired Renal Function Preoperatively. A Study of the Calcium Channel Blocker Nifedipine's Prophylactic Effect on Further Decline in Renal Function.

To compare renal function (51Cr-EDTA clearance) 48 hours post open-heart surgery (coronary bypass or valve surgery) in patients with impaired renal function after randomization to either nifedipine infusion at start of surgery and the following 24 hours or placebo (0.9% saline infusion). Study hypothesis is that nifedipine has a prophylactic effect on decline in renal function.
