[The effect of coronary intervention on renal function in patients with chronic renal failure].
To investigate the effect of coronary intervention on renal function in patients with chronic renal failure (CRF) we investigated 19 patients with CRF [serum creatinine (Scr) > 1.5 mg/dl] who underwent coronary intervention for the treatment of acute myocardial infarction or unstable angina recruited from 516 consecutive patients admitted to the coronary care unit of Nara Medical University Hospital from January, 1992 to July, 1995. Serum creatinine levels were measured at 3 points: on admission, at peak level, and at discharge. Nineteen patients were divided into two groups on the basis of increases in Scr (delta Scr): a worsened group (group A) (delta Scr > or = 1mg/dl after coronary intervention; 6 patients) and an unchanged group (group B) (delta Scr < 1 mg/dl ; 13 patients). In group A, except for one patient, the renal function recovered to the level before coronary intervention after adequate hydration or hemodialysis. The volume of contrast medium in group A (420 +/- 134 ml) was significantly higher than group B (253 +/- 97 ml) (p < 0.01). There was significant positive correlation (r = 0.42, p < 0.05) between delta Scr and the volume of contrast medium. In conclusion, coronary intervention for patients with CRF can be performed safely under treatment with adequate hydration and hemodialysis, even at higher serum creatinine levels of up to 4.0 mg/ml.
