Abstract
This study aimed to determine the efficacy of alprostadil in preventing contrast-induced nephropathy (CIN). Eligible studies were searched using the keywords through the databases of PubMed, Cochrane, Embase, China Biological Medicine Database, China National Knowledge Infrastructure, and Vanfun. Quality evaluation of the included studies was conducted according to international evidence evaluation and recommended Grades of Recommendations Assessment, Development, and Evaluation standards. We included 29 studies with 5623 patients. Compared with hydration, 10 µg/d alprostadil or 20 µg/d alprostadil plus hydration significantly decreased the incidence of CIN. Compared with hydration, alprostadil plus hydration significantly reduced serum creatinine and blood urea nitrogen at 24, 48, and 72 hours and 7 days after coronary angiography (CAG). Alprostadil (20 µg/d) plus hydration significantly decreased serum cystatin versus hydration at 24, 48, and 72 hours after CAG. Compared with hydration, alprostadil plus hydration significantly increased glomerular filtration rate at 24 and 72 hours after CAG. Alprostadil plus hydration significantly decreased neutrophil gelatinase-associated lipocalin levels compared to hydration at 24, 48, and 72 hours after CAG. Alprostadil plus hydration significantly decreased urine macroglobulin versus hydration at 24 and 48 hours after CAG.

Abstract
OBJECTIVE The aim of this meta-analysis was to synthesize the latest evidence on the effect of probucol on the incidence of contrast-induced nephropathy (CIN) in patients undergoing coronary angiography (CAG)/percutaneous coronary intervention (PCI). METHODS A systematic literature search of PubMed, ScienceDirect, EuropePMC, ProQuest, and Clinicaltrials. gov was performed to retrieve studies that assessed probucol and CIN in CAG/PCI. RESULTS Four studies that compared probucol with hydration alone, comprising 1270 subjects, were identified and analyzed. There was no significant difference between probucol and control groups in the baseline level of creatinine and at 48 hours; however, a significant difference was observed at 72 hours (mean difference: -3.87 μmol/L; 95% confidence interval [CI]: -6.58, -1.15; p=0.005). The meta-analysis indicated that probucol did not reduce the CIN incidence (odds ratio [OR]: 0.46; 95% CI: 0.20, 1.08; p=0.08). After performing a leave-one-out sensitivity analysis, removal of a study resulted in a lower risk of CIN (OR: 0.33; 95% CI: 0.19, 0.56; p<0.001). Probucol did not reduce the CIN incidence in a pooled adjusted effect estimate (OR: 0.75; 95% CI: 0.15, 3.87; p=0.73). There was no significant difference in the rate of major adverse events between the 2 groups (OR: 0.39; 95% CI: 0.05, 3.05; p=0.37). Funnel plot results were asymmetrical, indicating possible publication bias. Grading of Recommendations, Assessment, Development and Evaluations qualification demonstrated a low and very low certainty of evidence in unadjusted and adjusted effect estimates, respectively. CONCLUSION Probucol did not reduce the incidence of CIN; however, due to the low certainty of evidence, further study is required for a definite conclusion. Although the p value was not significant, the confidence interval showed a nonsignificant trend toward benefit. However, this trend might have been due to publication bias.

Abstract
BACKGROUND Renal insufficiency is an important predictor of contrast-induced acute kidney injury (CI-AKI). We performed a meta-analysis to examine the effects of short-term statin therapy on the incidence of CI-AKI, particularly in patients with renal insufficiency. METHODS A systematic search was conducted to retrieve randomized controlled trials (RCTs) that investigated the impact of statin pretreatment before administration of contrast media on the development of CI-AKI in patients with mild to moderate renal insufficiency. The primary outcome was development of CI-AKI. The secondary outcome was the incidence ofacute kidney injury requiring hemodialysis. RESULTS Data analysis from 8 RCTs, which included a total of 2313 subjects in the statin-treated group and 2322 in the control group, showed that statin pretreatment was associated with significant reduction of the risk of CI-AKI (relative risk [RR] = 0.59; 95% confidential interval [CI] 0.44-0.79; P = .0003, I = 0%). A beneficial effect of statin on preventing CI-AKI was consistent, regardless of the dose of statin and use of N-acetylcysteine. In subgroup analysis based on baseline estimated glomerular filtration rate (eGFR), patients with baseline eGFR <60 mL/min/1.73 m (RR = 0.63; 95% CI 0.41-0.98; P = .04, I = 0%) and 30 < eGFR < 90 mL/min/1.73 m (RR = 0.56; 95% CI 0.39-0.82; P = .003, I = 0%) showed significant reduction of risk of CI-AKI. CONCLUSION Statin pretreatment is effective at preventing CI-AKI and should be considered in patients with preexisting renal insufficiency.

Abstract
OBJECTIVES The objective of this meta-analysis on randomized controlled trials is to evaluate whether the administration of allopurinol with or without hydration will reduce contrast-induced acute kidney injury (CI-AKI) in patients undergoing contrast exposure. BACKGROUND The efficacy of allopurinol in the prevention of CI-AKI after cardiac catheterization and percutaneous coronary intervention (PCI) is significantly related to the heterogeneous results. METHODS Two investigators independently searched MEDLINE, EMBASE, the Cochrane Controlled Trials Registry, the China Wanfang Data, the China Biological Medicine Database and the China National Knowledge Infrastructure (CNKI) databases for randomized controlled trials (RCTs) comparing allopurinol with placebo or no allopurinol for the prevention of CI-AKI in patients from their inception to July 31, 2018. The primary outcome was the incidence of CI-AKI, and the secondary outcomes were the differences of serum creatinine (Scr), blood urea nitrogen (BUN), uric acid (UA), and estimated glomerular filtration rate (eGFR) levels between groups after contrast media exposure. We used fixed-effects or random-effects models according to I statistics. The meta-analytic procedures were completed by Review Manager, version 5.3. ACHIEVEMENTS Eight random controlled trials with 1141 patients were included for this analysis. Compared with the control, allopurinol was associated with a reduced risk of CI-AKI (Relatives Risk (RR) 0.39, 95% confidence interval [CI] 0.20,0.74, P = .004) and only a intend for decrease a post-procedure uric acid levels compared with the controlled ones at 48 hours (standardized mean difference (SMD) -0.72, 95% CI -1.44, 0.01, P = .05). But the difference of post-procedure uric acid levels was not statistically significant in allopurinol groups compared with controlled groups. There were lower post-procedure Scr and BUN levels in allopurinol groups than those in controlled groups (SMD -0.50, 95% CI -0.79,-0.21, P = .0009; SMD -0.40, 95% CI -0.60,-0.20, P < .0001;respectively). There were higher post-procedure eGFR levels in allopurinol groups than those in controlled groups (SMD 0.65, 95% CI 0.48, 0.83, P < .0001). CONCLUSION The main findings of this meta-analysis are focus on allopurinol may cause reduces in the incidence of CI-AKI in patients undergoing interventional coronary procedures. Further researches are still required for confirmation.

Angiology. 2019;(7):594-612
Abstract
Contrast-induced nephropathy (CIN) is the third leading cause of acquired acute renal injury in hospitalized patients. Alprostadil plays a role in the maintenance and redistribution of intrarenal blood flow and the excretion of electrolytes and water. However, the effectiveness of alprostadil in preventing CIN remains controversial. Thirty-six articles with a total of 5495 patients were included in this study. Both groups (experimental group and control group) received standard hydration therapy. In the experimental group, patients received different doses of alprostadil. Serum creatinine (SCr), blood urea nitrogen (BUN), estimated glomerular filtration rate (eGFR), cystatin C, creatinine clearance rate (CCr), and β2-microglobulin (β2-MG) were measured at 24, 48, and 72 hours after contrast media injection. The incidence of CIN in the experimental group was significantly lower than that in the control group (6.56% vs 16.74%). The level of SCr, cystatin C, BUN, and β2-MG in the experimental group was lower than those in the control group; CCr and eGFR in the experimental group were higher than those in the control group. This study demonstrated that alprostadil may reduce the incidence of CIN in patients undergoing coronary angiogram and/or percutaneous coronary intervention.

Abstract
BACKGROUND The efficacy of high-dose atorvastatin pretreatment in reducing the incidence of contrast-induced nephropathy in patients undergoing coronary angiography (CAG) or percutaneous coronary intervention (PCI) has been examined in some randomized studies. However, the results across the trials remain controversial. OBJECTIVE This study sought to perform a meta-analysis to evaluate the effect of high-dose atorvastatin in the prevention of contrast-induced nephropathy (CIN) while undergoing CAG or PCI. MATERIALS AND METHODS Comprehensive literature searches for randomized controlled trials (RCTs) comparing high-dose atorvastatin vs. low-dose statin or placebo pretreatment for prevention of contrast-induced acute kidney injury in patients undergoing CAG were performed using PubMed, Embase, and the Cochrane library updated to June 2017. The primary outcome was the incidence of CIN. RESULTS A total of 11 RCTs were included in this analysis. The high-dose atorvastatin treatment can significantly reduce the incidence of CIN (OR 0.46, 95% CI 0.35 - 0.62, p < 0.00001). The benefit was consistent in comparison with the low-dose group (OR 0.41, 95% CI 0.25 - 0.66, p = 0.0003) and the placebo group (OR 0.50, 95% CI 0.26 - 0.98, p = 0.04). CONCLUSION Our study demonstrates that high-dose statin pretreatment shows a benefit specifically in reducing the incidence of contrast-induced acute kidney injury in patients undergoing CAG, especially compared with low-dose statin pretreatment.

Abstract
BACKGROUND The effectiveness of oral hydration in preventing contrast-induced acute kidney injury (CI-AKI) in patients undergoing coronary angiography or intervention has not been well established. This study aims to evaluate the efficacy of oral hydration compared with intravenous hydration and other frequently used hydration strategies. METHODS PubMed, Embase, Web of Science, and the Cochrane central register of controlled trials were searched from inception to 8 October 2017. To be eligible for analysis, studies had to evaluate the relative efficacy of different prophylactic hydration strategies. We selected and assessed the studies that fulfilled the inclusion criteria and carried out a pairwise and network meta-analysis using RevMan5.2 and Aggregate Data Drug Information System 1.16.8 software. RESULTS A total of four studies (538 participants) were included in our pairwise meta-analysis and 1754 participants from eight studies with four frequently used hydration strategies were included in a network meta-analysis. Pairwise meta-analysis indicated that oral hydration was as effective as intravenous hydration for the prevention of CI-AKI (5.88 vs. 8.43%; odds ratio: 0.73; 95% confidence interval: 0.36-1.47; P>0.05), with no significant heterogeneity between studies. Network meta-analysis showed that there was no significant difference in the prevention of CI-AKI. However, the rank probability plot suggested that oral plus intravenous hydration had a higher probability (51%) of being the best strategy, followed by diuretic plus intravenous hydration (39%) and oral hydration alone (10%). Intravenous hydration alone was the strategy with the highest probability (70%) of being the worst hydration strategy. CONCLUSION Our study shows that oral hydration is not inferior to intravenous hydration for the prevention of CI-AKI in patients with normal or mild-to-moderate renal dysfunction undergoing coronary angiography or intervention.

Abstract
BACKGROUND Invasive coronary procedures involve the administration of iodinated contrast and the exposure to ionising radiations, increasing morbidity and mortality. The rotational coronary angiography (RCA) allows acquiring multiple projections with a unique injection of iodinated contrast. To date, there are no meta-analyses specifically comparing RCA and conventional coronary angiography (CCA) in patients undergoing invasive coronary procedures, whether diagnostic or diagnostic and therapeutic. The aim of this meta-analysis is to assess the impact of RCA on the amount of iodinated contrast and the exposure to ionising radiations during invasive coronary procedures. METHODS A search in PubMed and Ovid databases was conducted to identify studies, including diagnostic and diagnostic and therapeutic studies, comparing RCA and CCA. The manuscripts were evaluated on quality and biases, and were included if they analysed any of the following endpoints: volume of contrast and exposure to ionising radiations measured as dose-area product, and Kerma-air or fluoroscopy time. RESULTS Sixteen studies, with a total of 2,327 patients, were included in the final analysis (1,146 patients underwent RCA and 1,181 patients underwent CCA), with significant differences being detected in volume of contrast (standard difference in means [95% confidence interval] -1.887 [-2.472 to -1.302]; P<.001), dose-area product (-0.726 [-1.034 to -0.418]; P<.001), Kerma-air (-0.842 [-1.104 to -0.581]; P<.001), and fluoroscopy time (0.263 [-0.496 to -0.030]; P=.027). CONCLUSIONS RCA reduces the volume of contrast and the exposure to radiation, evaluated as dose-area product, Kerma-air, and fluoroscopy time, in patients undergoing invasive coronary procedures.

Abstract
BACKGROUND The effectiveness of currently available effective preventive strategies for contrast-induced acute kidney injury (CIAKI) is a matter of debate. METHODS AND RESULTS We performed a Bayesian random-effects network meta-analysis of 124 trials (28 240 patients) comparing a total of 10 strategies: saline, statin, N-acetylcysteine (NAC), sodium bicarbonate (NaHCO3), NAC+NaHCO3, ascorbic acid, xanthine, dopaminergic agent, peripheral ischemic preconditioning, and natriuretic peptide. Compared with saline, the risk of CIAKI was reduced by using statin (odds ratio [OR], 0.42; 95% credible interval [CrI], 0.26-0.67), xanthine (OR, 0.32; 95% CrI, 0.17-0.57), ischemic preconditioning (OR, 0.48; 95% CrI, 0.26-0.87), NAC+NaHCO3 (OR, 0.50; 95% CrI, 0.33-0.76), NAC (OR, 0.68; 95% CrI, 0.55-0.84), and NaHCO3 (OR, 0.66; 95% CrI, 0.47-0.90). The benefit of statin therapy was consistent across multiple sensitivity analyses, whereas the efficacy of all the other strategies was questioned by restricting the analysis to high-quality trials. Overall, high heterogeneity was observed for comparisons involving xanthine and ischemic preconditioning, although the impact of NAC and xanthine was probably influenced by publication bias/small-study effect. Hydration alone was the least effective preventive strategy for CIAKI. Meta-regressions did not reveal significant associations with baseline creatinine and contrast volume. In patients with diabetes mellitus, no strategy was found to reduce the incidence of CIAKI. CONCLUSIONS In patients undergoing percutaneous coronary procedures, statin administration is associated with a marked and consistent reduction in the risk of CIAKI compared with saline. Although xanthine, NAC, NaHCO3, NAC+NaHCO3, ischemic preconditioning, and natriuretic peptide may have nephroprotective effects, these results were not consistent across multiple sensitivity analyses.

Abstract
OBJECTIVES This study sought to determine prognostic value of nonobstructive coronary artery disease (CAD) for atherosclerotic cardiovascular disease (ASCVD) events and to determine whether incorporation of this information into the pooled cohort equation reclassifies recommendations for statin therapy as defined by the 2013 guidelines for cholesterol management of the American College of Cardiology and American Heart Association (ACC/AHA). BACKGROUND Detection of nonobstructive CAD by coronary computed tomography angiography may improve risk stratification and permit individualized and more appropriate allocation of statin therapy. METHODS This study determined the pooled hazard ratio of nonobstructive CAD for ASCVD events from published studies and incorporated this information into the ACC/AHA pooled cohort equation. The study calculated revised sex- and ethnicity-based 10-year ASCVD risk and determined boundaries corresponding to the original 7.5% risk for ASCVD events. It also assessed reclassification for statin eligibility by incorporating the results from meta-analysis to individual patients from a separate cohort. RESULTS This study included 2 studies (2,295 subjects; 66% male; prevalence of nonobstructive CAD, 47%; median follow-up, 49 months; 67 ASCVD events). The hazard ratio of nonobstructive CAD for ASCVD events was 3.2 (95% confidence interval: 1.5 to 6.7). Incorporation of this information into the pooled cohort equation resulted in reclassification toward statin eligibility in individuals with nonobstructive CAD, with an original ASCVD score of 3.0% and 5.9% or higher in African-American women and men and a score of 4.4% and 4.6% or higher in Caucasian women and men, respectively. The absence of nonobstructive CAD resulted in reclassification toward statin ineligibility if the original ASCVD score was as 10.0% and 17.9% or lower in African-American women and men and 13.7% and 14.3% or lower in Caucasian women and men, respectively. Reclassification is observed in 14% of patients. CONCLUSIONS Detection of nonobstructive CAD by coronary computed tomography angiography improves risk stratification and permits individualized and more appropriate allocation of statin therapy across sex and ethnicity groups.
