The present study was conducted to investigate the relationship between hyperuricemia (HUA) and CIN in patients after emergent PCI. Methods A total of 558 consecutive patients with ACS undergoing emergent PCI in Fujian Provincial Hospital were enrolled in this study. Patients were divided into hyperuricemic group (n=136) and normouricemic group (n=422). Hyperuricemia was defined as SUA 〉420 μmol/L for male, 〉 360 txmol/L for female. CIN was defined as an absolute ≥44.2 μmol/L(0.5 mg/dL) increase inthe serum creati- nine (SCr) level within 72 hours after contrast medium exposure. In hospital incidences of CIN and the major adverse cardiac events were compared between the two groups. The relationship between the incidence of CIN and HUA was evaluated by multivariate logistic regression analysis. Results Among the 558 patients, CIN was observed in 34(6.1%) patients, and incidence of CIN was significantly higher in the HUA group than in the normou- ricemic group [13.2% (18/136) vs. 3.8%(16/422), P 〈 0.001]. SUA concentration was significantly higher in CIN group compared with that in non - CIN group [ (490.21±76.48 μmol/L) vs. (307.00±65.37μmol/L), P 〈 0.001]. Need for renal replacement therapy (RRT), congestive heart failure (CHF), in hospital mortality after PCI were significantly higher in the HUA group compared with Normouricemic group (all P〈0.05). Patients who devel- oped CIN had higher in hospital mortality [44.1% (15/34) vs. 2.9 % (15/524), P 〈 0.001 ]. Multivariate analysis in- dicates that HUA(OR=3.020, 95% CI: 1.3340- 6.805, P 〈 0.001), Intra- aortic balloon pump (IABP) use (OR= 15.724,95% CI: 3.913-63.179, P 〈 0.001) and Perioperative hypotension(OR=3.342, 95% CI: 1.373-8.138, P 〈 0.01) were predictors of CIN in patients after emergent percutaneous coronary intervention. Conclusion Hyper- uricemia is the independent risk predictor of CIN in patients with ACS undergoing emergent PCI.展开更多

The present study was conducted to evaluate the effects of different composite hydration rate (intravenous plus oral) on CIN prevention in patients undergoing emergent percutaneous coronary intervention (PCI). Methods This was a retrospective observational study that included 307 eligible patients, who were stratified into quartiles of rate of the composite hydration volumn to body weight and time (HV/ W/T). CIN was defined as an absolute≥0.5 mg/dL or a relative ≥25% increase in the serum creatinine level within 72 hours after the procedure. Results In terms of risks of CIN, there were no statistical differences among individuals in four groups with different composite HV/W/T (27.6%, 19.0%, 23.0%, and 26.9% respectively in quartiles Q1, Q2, Q3, and Q4, P=0.565). Additionally, higher composite hydration ratio seemed not to decrease the risk of in-hospital death, worsening heart failure and stroke (all P〉0.05). After adjusting for other risk factors, multivariate analysis showed no statistical difference between Q2, Q3 or Q4, compared with Q1 (Q2 vs. QI: adjusted odds ratio [OR], 0.67, P=0.383; Q3 vs QI: adjusted OR, 0.77, P=0.550; Q4 vs. QI: adjusted OR, 0.75, P= 0.489). Conclusion Excessive composite hydration may not provide supplemental benefit of CIN prevention and in-hospital outcomes in patients following emergent PCI, and moderate and prophylactic hydration is warranted.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 = 16.26, P = 0.009 at 6-month follow-up, and χ^2 = 49.05, P 〈 0.001 at 12-month follow-up). The logistic analysis confirmed that eGFR was one of independent risk factors of CI-AKI in emergency PCI patients. Conclusions: High level ofeGFR might be associated with increased risk of CI-AKI in patients with emergency PCI, implying for future studies and risk stratification in clinical practice.展开更多
