Some studies pointed out that it was effective in the prevention of CI-AKI, while some concluded that it was one risk for CI-AKI, especially for patients with pre-existing renal impairment. The purpose of this study was to assess the influence of benazepril administration on the development of CI-AKI in patients with mild to moderate renal insufficiency undergoing coronary intervention.Methods One hundred and fourteen patients with mild to moderate impairment of renal function were enrolled before coronary angioplasty, who were randomly assigned to benazepril group （n=52） and control group （n=62）. In the benazepril group, the patients received benazepril tablets 10 mg per day at least for 3 days before procedure. CI-AKI was defined as an increase of≥25％ in creatinine over the baseline value or increase of 0.5 mg/L within 72 hours of angioplasty.Results Patients were well matched with no significant differences at baseline in all measured parameters between two groups. The incidence of CI-AKI was lower by 64％ in the benazepril group compared with control group but without statistical significance （3.45％ vs. 9.68％, P=0.506）. Compared with benazepril group, estimated glomerular filtration rate （eGFR） level significantly decreased from （70.64＋16.38） ml·min-1·1.73 m-2 to （67.30＋11.99） ml·min-1·1.73 m-2 in control group （P=0.038）. There was no significant difference for the post-procedure decreased eGFR from baseline （△eGFR）between two groups （benazepril group （0.67＋12.67） ml·min-1·1.73 m-2 vs. control group （-3.33±12.39） ml·min-1·1.73 m-2,P=0.092）. In diabetic subgroup analysis, △eGFR in benazepril group was slightly lower than that in the control group, but the difference was not statistically significant.Conclusions Benazepril has a protective effect on mild to moderate impairment of renal function du展开更多

The aim of this study was to explore the risk factors of CI-AKi in a Chinese population undergoing emergency PCI. Methods： A total of 1061 consecutive patients undergoing emergency PCI during January 2013 and June 2015 were enrolled and divided into CI-AK1 and non-CI-AKl group. Univariable and multivariable analyses were used to identity the risk factors of CI-AKI in emergency PCI patients. CI-AKI was defined as an increase in serum creatinine ≥25% or ≥0.5 mg/dl （44.2 μmol/L） above baseline within 3 days alter exposure to contrast medium. Results： The incidence of C1-AKI in patients undergoing emergency PCI was 22.7% （241/1061）. Logistic multivariable analysis showed that body surface area （BSA） （odds ratio [OR] 0.213, 95% confidence interval [CI]： 0.075-0.607, P = 0.004）, history, of myocardial infarction （MI） （OR 1.642, 95% CI. 1.079-2.499, P- 0.021 ）, left ventricular ejection fraction （LVEF） （OR 0.969, 95% CI： 0.944-0.994, P = 0.015）, hemoglobin （Hb） （OR 0.988, 95% CI. 0.976-1.000, P 1.018 1.037, P 〈 0.001 ）, left anterior descending （LAD） stented （OR 1 0.009 0.987, P- 0.049）, and diuretics use （OR 1.850, 95% CI： 1.233-2 0.045）, estimated glomerular filtration rate （OR 1.027, 95% CI： 464, 95% CI： 1.000 2.145, P 0.050）, aspirin （OR 0.097, 95%CI： .777, P - 0.003） were independent predictors of CI-AKI in patients undergoing emergency PCI. Conclusion： History of MI, low BSA, LVEF and Hb level, LAD stented, and diuretics use are associated with increased risk of CI-AK1 in patients undergoing emergency PCI.展开更多

However, high level of eGFR was less reported. In the study, we aimed to explore the relationship between the baseline eGFR, especially the high level, and contrast-induced acute kidney injury （CI-AKI） in a Chinese population who underwent an emergency percutaneous coronary intervention （PCI）. Methods： Patients who underwent an emergency PCI from 2013 to 2015 were enrolled and divided into five groups as eGFR decreasing. Baseline characteristics were collected and analyzed. The rates of CI-AKI and the composite endpoint （including nonfatal myocardial infarction, revascularization, stroke, and all-cause death） at 6- and 12-month follow-up were compared. Logistic analysis for CI-AKI was performed.Results： A total of 1061 patients were included and the overall CI-AKI rate was 22.7% （241 / 1061）. The separate rates were 77.8% （7/9） in Group 1 （eGFR 〉 120 ml·min^-1 -1.73 m^-2）, 26.0% （118/454） in Group 2 （120 ml·min^-1·min^-11.73 m^-2〉 eGFR≥90 ml·min^-1 1.73^-2）, 18.3% （86/469） in Group 3 （90 ml·min^-1 1.73 m^-2〉 eGFR 〉60 ml·min^-1·min^-11.73 m^-2）, 21.8% （26/119） in Group 4 （60 ml·min^-1·1.73 m^-2〉 eGFR≥30 ml·min^-1·min^-11.73 m^-2）, and 40.0% （4/10） in Group 5 （eGFR 〈30 ml·min^-1·min^-1·min^-11.73 m^-2）, with statistical significance （χ^2 = 25.19, P 〈 0.001）. The rates of CI-AKI in five groups were 77.8%, 26.0%, 18.3%, 21.8%, and 40.0%, respectively, showing a U-typed curve as eGFR decreasing （the higher the level of eGFR, the higher the CI-AKI occurrence in case ofeGFR_〉60 ml·min^-1·1.73 m^-2）. The composite endpoint rates in five groups were 0, 0.9%, 2.1%, 6.7%, and 0 at 6-month follow-up, respectively, and 0, 3.3%, 3.4%, 16.0%, and 30.0% at 12-month follow-up, respectively, both with significant differences （χ^2 = 展开更多
