The effect of intensive atorvastatin treatment on kidney function in patients after percutaneous coronary intervention / 安徽医科大学学报

ABSTRACT

Objective To investigate whether intensive atorvastatin treatment in patients after percutaneous coro-nary intervention ( PCI) could decrease the effect of contrast medium on kidney function and the incidence of con-trast-induced acute kidney injury( CI-AKI) . Methods A total of 128 patients with PCI were randomly divided into two groupsthe enhanced treatment group (n=64) and the control group(n=64). The enhanced treatment group received 80 mg atorvastatin at 12~24 h before PCI and 24,48 h after PCI. The control group was given 20 mg ator-vastatin respectively before and after PCI. The primary end point was the incidence of CI-AKI. Serum creatinine (Scr), cystatin C, glomerular filtration rate(eGFR), urinary albumin and urinary β-2 microglobulin levels were observed at 24 h before PCI and 24, 48, 72 h after PCI. Results In the enhanced treatment group 3. 1 % (n=2) of patients developed CI-AKI versus 4. 7 % (n=3) in the control group, without statistical difference (P=1.00). There was no significant difference between two groups in postoperative Scr, cystatin C, eGFR, urinary al-bumin, urinary β-2 microglobulin and creatine kinase(CK). Three days after the operation, alanine aminotrans-ferase ( ALT) elevated in two groups, and aspartate aminotransferase ( AST) increased in the enhanced treatment group (P<0. 05), but they were all in the normal range. Conclusion There has been no significant difference in decreasing the incidence of CI-AKI and the damage of contrast medium on renal function between the enhanced treatment group and the control group before PCI.
