The nephroprotective effects of prostaglandin E1 in the elderly undergoing coronary angiography or intervention treatment / 中华老年医学杂志

ABSTRACT

Objective To investigate the nephroprotective effects of prostaglandin E1 (PGE1) in the elderly undergoing coronary angiography or intervention. Methods161 patients undergoing coronary angiography (CAG) or percutaneous coronary intervention (PCI) were randomly assigned to PGE1 group (n=87 cases) and control group (n=74 cases).10 μg lipo-PGE1 added to 100 ml normal saline were administered intravenously once daily for 5 days before and 2 days after the operation.The serum levels of creatinine (Scr) and cystatin C (Cys C) were measured on admission and 48 h after the procedure.Results After the procedure,the levels of Scr and Cys C were increased (P＜0.01) and creatinine clearance (Ccr) was decreased (P＜0.05) in control group than in PGE1 group.The incidence of contrast-induced acute kidney injury (CI-AKI) in control group 〔12.2％ (9/74)〕 was higher than in PGE1 group 〔3.4％(3/87)〕 (P＜0.05).The application of P(GE1 decreased CI-AKI,but high basic level of Scr and diabetes mellitus enhanced the incidence of CI-AKI by logistic regression.The serum levels of Cys C had negative correlation with Ccr (r=-0.615,P＜0.01).Conclusions Perioperative application of PGE1 has nephroprotective effects in the elderly undergoing CAG or PCI,and decreases the incidence of CI-AKI.The serum levels of Cys C is one of ideal indexes for auxiliary diagnosis of CI-AKI.
