Abstract: Objective To observe the effects of long-term use of angiotensin-converting enzyme inhibitor (ACEI) or angiontensin receptor blocker(ARB) on the renal function in the elderly patients receiving percutaneous coronary intervention (PCI). Methods A total of 112 elderly patients with normal or mild abnormal renal function who underwent PCI were divided into observation group (using ACEI or ARB, n=58) and control group (not using ACEI or ARB, n=54). The serum level of creatinine(CRE) and glomerular filtration rate(eGFR) before or 24, 48 hours after PCI were detected and compared between the two groups. Results The level of CRE was significantly higher and the level of eGFR was significantly lower in both groups 24, 48 hours after PCI than that before PCI, especially in observation group (P<0.05). One patient(1.85%) presented with contrast-induced nephropathy (CIN) in control group. There was no statistical difference in the incidence rate of CIN between two goups (P=0.482). Conclusions In the elderly patients undergoing coronary intervention,long-term use of ACEI or ARB would reduce the effect of contrast medium on the renal function,but does not show a significant adverse effect on the incidence of CIN.
