RESUMO

OBJECTIVES: To assess the predictive value of the Global Registry of Acute Coronary Events (GRACE) discharge score for patients with stable coronary artery disease (SCAD) after percutaneous coronary intervention (PCI). BACKGROUND: The GRACE score is widely used for predicting the mortality of acute coronary syndrome patients. However, the predictive value of SCAD has not been sufficiently studied. METHODS: We studied 4,293 consecutive patients with SCAD who underwent PCI between January 2013 and December 2013. The primary endpoint was all-cause mortality and the secondary endpoint was major adverse cardiovascular and cerebrovascular events (MACCE). RESULTS: Among 3,915 patients with SCAD following PCI, there were 38 deaths and 394 MACCE during 2 years of follow-up. The GRACE discharge score was significantly higher for patients who died than for those who survived (86.97 ± 23.27 vs. 71.07 ± 19.84; p < .001). Risk stratification of the GRACE score indicated that the mortality risk of the intermediate-risk and high-risk groups were 3.23-fold (hazard ratio [HR], 3.23; range, 1.59-6.55; p = .001) and 15.31-fold higher (HR, 15.31; range, 4.43-51.62; p < .001), respectively, than that of the low-risk group. The MACCE risk for the intermediate-risk and high-risk groups were 1.28-fold (HR, 1.28; range, 1.02-1.62; p = .037) and 2.42-fold higher (HR, 2.42; range, 1.20-4.88; p = .014), respectively. The GRACE discharge score had prognostic value for mortality (area under the receiver operating characteristic curve, 0.692; p < .001). CONCLUSIONS: The GRACE discharge score is valuable for the risk stratification of death and MACCE, as well as for the prognosis to mortality for SCAD patients who have undergone PCI.

RESUMO

BACKGROUND AND AIMS: The association between lipoprotein(a) [Lp(a)] levels and the risk of cardiovascular disease is of great interest but still controversial. This study sought to investigate the impact of Lp(a) on coronary severity and long-term outcomes of patients who undergo percutaneous coronary intervention (PCI). METHODS AND RESULTS: A total of 6714 consecutive patients who received PCI were enrolled to analyze the association between Lp(a) and coronary severity and major adverse cardiovascular and cerebrovascular events (MACCE). Patients were divided into tertiles according to Lp(a) levels on admission. Coronary severity was evaluated by SYNTAX scoring system. The MACCE included recurrent myocardial infarction, unplanned target vessel revascularization, stent thrombosis, ischemic stroke and all-cause mortality. Significantly, Lp(a) levels were positively associated with coronary severity (p < 0.001). Multivariate logistic regression analyses showed Lp(a) was an independent predictor of intermediate to high SYNTAX score. During an average of 874 days follow-up, 755 patients presented with MACCE (11.25%) were reported. The incidence rates of MACCE, all-cause mortality, cardiac death, target vessel revascularization, recurrent myocardial infarction, stent thrombosis, stroke and bleeding were not statistically different among the Lp(a) tertile groups. Furthermore, both Kaplan-Meier and Cox regression analyses found no relationship between Lp(a) and cardiovascular outcomes (p > 0.05). CONCLUSION: Lp(a) is an independent predictor of the prevalence of more complex coronary artery lesions (SYNTAX score ≥ 23) in patients with PCI. In addition, our study has shown that Lp(a) has no relationship with long-term cardiovascular outcomes in Chinese patients with PCI.

RESUMO

BACKGROUND: Inflammation plays a pivotal role in coronary artery disease (CAD). Few data from large-size studies are available on the association of high-sensitivity C-reactive protein (hs-CRP) and severity of CAD. Our aim was to investigate their relationship as well as their impact on long-term outcomes in patients undergoing percutaneous coronary intervention. METHODS: In 2013, 10,020 patients were consecutively included. Patients were divided into three groups based on hs-CRP on admission: 0-3mg/L (n=6978, 69.6%), 3.01-10mg/L (n=1997, 19.9%), >10mg/L (n=1045, 10.4%). Disease severity was determined by SYNTAX score (SS). Their differences were assessed in SS and major adverse cardiovascular events (MACEs, including all-cause death, myocardial infarction, revascularization, and in-stent thrombosis) among groups. RESULTS: The mean follow-up period was 874 days. Patients with elevated hs-CRP were older, had more risk factors such as hypertension, cerebrovascular disease, chronic obstructive pulmonary disease, and cigarette smoking. Multivariate regression analysis showed that hs-CRP >10mg/L (OR 1.49, 95% confidence interval 1.21-1.84, p<0.001), age, previous myocardial infarction, serum creatinine, and left ventricular ejection fraction were independent predictors of intermediate-high SS (>22). Subgroup analysis indicated that the relation between hs-CRP and SS was also consistent in acute coronary syndrome and its subtypes. Although elevated hs-CRP was positively associated with increased rates of MACEs (11.0% versus 12.1% versus 14.3%, p=0.006), death (1.0% versus 1.3% versus 3.0%, p<0.001), and revascularization (8.6% versus 10.4% versus 10.0%, p=0.032), it did not show any prognostic effect for adverse outcomes in multivariate regression analyses (all adjusted p> 0.05). While SS>22 remained independently predictive of MACEs and revascularization after adjusting confounders, the risks of which were increased by 56% and 68%, respectively. CONCLUSION: Serum hs-CRP could be a useful biomarker for indicating CAD severity and could aid in risk stratification.

RESUMO

OBJECTIVE: Identification of new risk factors is needed to improve prediction of adverse outcomes in patients with three-vessel disease (TVD). The present study aimed to evaluate the prognostic values of serum chloride and sodium levels in patients with TVD. METHODS: We used data from a prospective cohort of consecutive patients with angiographically confirmed TVD. The primary endpoint was all-cause death. Cox proportional hazard regression was used to analyze the relationship of serum chloride and sodium levels with long-term outcomes of TVD patients. RESULTS: A total of 8,318 participants with available serum chloride and sodium data were included in this analysis. At baseline, patients in the low tertiles group of serum chloride level (⪕ 102.0 mmol/L) or serum sodium level (⪕ 139.0 mmol/L) had more severe disease conditions. During a median follow-up of 7.5-year, both low serum chloride level and low serum sodium level were found to be associated with an increased risk for mortality in univariate analysis. However, when both parameters were incorporated into a multivariate model, only low serum sodium level remained to be an independent predictor of all-cause death (hazard ratio: 1.16, 95% confidence interval: 1.01-1.34, P = 0.041). Modest but significant improvement of discrimination was observed after incorporating serum sodium level into the Synergy between percutaneous coronary intervention (PCI) with Taxus and Cardiac Surgery score. CONCLUSION: Serum sodium level is more strongly associated with long-term outcomes of TVD patients compared with serum chloride level. Low serum sodium level is an independent risk factor for mortality, but only provides modest prognostic information beyond an established risk model.

RESUMO

BACKGROUND: A novel risk model to predict long-term mortality in patients with acute coronary syndrome (ACS), derived from the EPICOR (long-term follow-up of antithrombotic management patterns in acute coronary syndrome patients) registry, has been released recently and its performance remains to be assessed. The objective is to evaluate the EPICOR score for 2-year mortality risk in ACS patients after percutaneous coronary intervention (PCI). METHODS: From January to December in 2013, a total of 6087 consecutive patients presenting with ACS who were scheduled for PCI were enrolled. Use online simplified EPICOR calculator to assess the expected risk of death. RESULTS: Sixty-eight patients (1.1%) died during 2-year follow-up. The areas under the receiver operating characteristics curve for mortality in the overall population, ST-segment elevation myocardial infarction (STEMI), and non-ST-segment elevation ACS were 0.712 (95% CI, 0.650-0.772; p < 0.001), 0.790 (95% CI, 0.676-0.903; p < 0.001), and 0.683 (95% CI, 0.615-0.751; p < 0.001), respectively. Moreover, it was noninferior to the updated Global Registry of Acute Coronary Events (GRACE) risk score. Patients were stratified into three categories: low-risk (n = 3382), medium-risk (n = 2547), and high-risk (n = 158). Kaplan-Meier curve demonstrated significant ongoing divergence in both mortality (0.6% vs 1.3% vs 9.5%; p < 0.001) and major adverse cardiovascular and cerebrovascular events (MACCEs) (11.8% vs 12.3% vs 19.6%; p = 0.014) among them. Multivariate Cox analysis revealed that medium- and high-risk groups predicted 2- and 12-fold hazards of death comparing to the lowest. Yet, it was not a significant predictor for MACCEs after adjusting confounding factors. CONCLUSION: The simplified EPICOR score showed fair discriminatory power of 2-year mortality in patients with ACS and an improved performance in the STEMI subgroup. It could aid in risk stratification of ACS patients as an independent predictor.

RESUMO

BACKGROUND: It is currently unclear if fibrinogen is a risk factor for adverse events in patients receiving percutaneous coronary intervention (PCI) or merely serves as a marker of pre-existing comorbidities and other causal factors. We therefore investigated the association between fibrinogen levels and 2-year all-cause mortality, and compared the additional predictive value of adding fibrinogen to a basic model including traditional risk factors in patients receiving contemporary PCI. METHODS: A total of 6293 patients undergoing PCI with measured baseline fibrinogen levels were enrolled from January to December 2013 in Fuwai Hospital. Patients were divided into three groups according to tertiles of baseline fibrinogen levels: low fibrinogen, <2.98 g/L; medium fibrinogen, 2.98 to 3.58 g/L; and high fibrinogen, ≥3.58 g/L. Independent predictors of 2-year clinical outcomes were determined by multivariate Cox proportional hazards regression modeling. The increased discriminative value of fibrinogen for predicting all-cause mortality was assessed using the C-statistic and integrated discrimination improvement (IDI). RESULTS: The 2-year all-cause mortality rate was 1.2%. It was significantly higher in the high fibrinogen compared with the low and medium fibrinogen groups according to Kaplan-Meier analyses (1.7% vs. 0.9% and 1.7% vs. 1.0%, respectively; log-rank, P = 0.022). Fibrinogen was significantly associated with all-cause mortality according to multivariate Cox regression (hazard ratio 1.339, 95% confidence interval: 1.109-1.763, P = 0.005), together with traditional risk factors including age, sex, diabetes mellitus, left ventricular ejection fraction, creatinine clearance, and low-density lipoprotein cholesterol. The area under the curve for all-cause mortality in the basic model including traditional risk factors was 0.776, and this value increased to 0.787 when fibrinogen was added to the model (IDI = 0.003, Z = 0.140, P = 0.889). CONCLUSIONS: Fibrinogen is associated with 2-year all-cause mortality in patients receiving PCI, but provides no additional information over a model including traditional risk factors.

RESUMO

OBJECTIVES: The aim of this study was to investigate the operability, 6-month efficacy, and safety of the novel sirolimus-eluting iron bioresorbable coronary scaffold (IBS) system compared with a cobalt-chromium everolimus-eluting stent (EES) (XIENCE Prime stent) in porcine coronary arteries. BACKGROUND: Bioresorbable scaffolds have been considered the fourth revolution in percutaneous coronary intervention. However, the first-generation bioresorbable scaffold showed suboptimal results. METHODS: Forty-eight IBS and 48 EES were randomly implanted into nonatherosclerotic swine. The operability, efficacy, and safety of the IBS and EES were evaluated using coronary angiography, optical coherence tomography, micro-computed tomography, scanning electron microscopy, and histopathologic evaluation at 7, 14, 28, 90, and 180 days after implantation. RESULTS: The operability of the ultrathin IBS (∼70 µm) was comparable with that of the EES, except for its visibility. There was no statistically significant difference in area stenosis between the IBS and EES from 28 to 180 days. The IBS maintained its integrity up to 90 days without corrosion, while corrosion was observed in a few struts in 2 of 10 IBS at 180 days. The percentage of endothelialization of IBS was higher than that of XIENCE Prime stents within 14 days after implantation. The fibrin score was higher in the IBS group at 28 days but comparable with the EES group at 90 and 180 days. No scaffold or stent thrombosis was seen in either group. No abnormal histopathologic changes in scaffolded or stented vessel segments and 5 main remote organs were observed in either group. CONCLUSIONS: Preclinical results suggest that the novel IBS has comparable operability, mid-term efficacy, and safety with the EES, and its corrosion profile in porcine coronary arteries is reasonable, which could support initial clinical study of the IBS.

RESUMO

This study aimed to evaluate the platelet reactivity in real-world patients with different chronic kidney disease (CKD) stages after percutaneous coronary intervention (PCI), and to examine whether high residual platelet reactivity (HRPR) is associated with higher incidence of adverse cardiovascular events in a 2-year follow up. A total of 10 724 consecutive patients receiving DAPT with aspirin and clopidogrel after PCI throughout 2013 were enrolled. We applied modified thromboelastography (mTEG) in 6745 patients. Kaplan-Meier analysis and Cox proportional regression analysis were applied to illustrate end points for patients. The prevalence of HRPR for adenosine diphosphate (ADP) was higher in patients with CKD3-5 than patients with CKD1-2 (47.0% vs. 37.3%, p = 0.002), but not for arachidonic acid (AA). No significant difference was observed for MACCE between patients with or without HRPR for ADP (HR 1.004, 95%CI: 0.864-1.167, p = 0.954). Patients with HRPR for ADP was associated with less bleeding events than patients without HRPR for ADP (HR 0.795, 95%CI: 0.643-0.982, p = 0.034). In this large cohort of real-world patients after PCI, the deterioration of renal function was linked to HRPR for ADP. HRPR was not associated with MACCE in patients with CKD in a 2-year follow up. Bleeding risks were significantly lower in PCI patients with versus without HRPR for ADP.

RESUMO

OBJECTIVES: To evaluate the effect of prior stroke on long-term outcomes in patients undergoing percutaneous coronary interventions (PCI). BACKGROUND: Patients with coronary heart disease (CHD) and prior stroke history have more serious clinical and angiographic conditions, which make the choice of treatment strategy complex. METHODS: A total of 10,724 consecutive patients who underwent PCI from January 2013 to December 2013 were enrolled. 2-Year clinical outcomes between patients with prior stroke (n = 1150) and those with no prior stroke (n =9574) were compared. RESULTS: The proportion of patients with prior stroke was 10.72%. These patients had higher clinical risks (age, sex, and cardiovascular risk factors) and more extensive coronary disease (higher pre-PCI and residual SYNTAX scores). During the 2-year follow-up, patients with prior stroke had a higher incidence of major adverse cardiac and cerebrovascular events (MACCE), all-cause death, stent thrombosis and stroke than those without prior stroke (14.3% vs. 11.8%, p = 0.02; 2.3% vs. 1.1%, p < 0.01; 1.6% vs. 0.8%, p < 0.01; 3.3% vs. 1.1%, p < 0.01, respectively). Multivariable regression analyses identified a positive association between prior stroke and risk of stroke (HR = 2.07, 95%CI: 1.35-3.19, p < 0.01). Propensity score matched analyses (962 pairs) indicated that the only primary end point that differed in incidence between the groups was stroke and prior stroke was the only independent predictor of stroke (HR = 2.31, 95%CI: 1.20-4.45, p = 0.01). CONCLUSIONS: Prior stroke history was the only predictor of risk of post-PCI stroke. The noncerebrovascular adverse events were not increased after adjusted analyses of baseline characteristics and propensity analyses.

RESUMO

BACKGROUND: Mean platelet volume (MPV) is a marker of platelet size and activity, and is associated with a poor prognosis of cardiovascular disease. Studies have shown a relationship between diabetes mellitus (DM) and MPV. This study examined the relationship between admission MPV and 2-year cardiac mortality in patients with DM and stable coronary artery disease (SCAD) undergoing elective percutaneous coronary intervention (PCI). METHODS: A total of 1389 patients were enrolled and divided into two groups according to MPV as fol- lows: lower MPV (n = 908, MPV ≤ 10.9 fL) and higher MPV (n = 481, MPV > 10.9 fL). RESULTS: Body mass index, platelet distribution width, MPV/platelet and glycated hemoglobin (HbA1c) levels were significantly higher in the higher MPV group compared with the lower MPV group (all p < 0.05). The platelet count was significantly lower in the higher MPV group compared with the lower MPV group (p < 0.05). MPV was positively associated with HbA1c and fasting plasma glucose levels (r = 0.073 and 0.061, p = 0.007 and 0.023, respectively) in bivariate correlation analysis. The 2-year cardiac mortality rate was 0.7%, and was significantly lower in the lower MPV group than in the higher MPV group in Kaplan-Meier analysis (p = 0.019). Receiver operating characteristic analysis showed a good diagnostic value for MPV at predicting long-term cardiac mortality (area under the curve: 0.735, 95% confidence interval [CI]: 0.590-0.880, p = 0.01). Elevated MPV was a significant risk factor for 2-year cardiac mortality (hazard ratio: 2.091, 95% CI: 1.075-4.070, p = 0.030) in multivariable Cox regression analysis. CONCLUSIONS: Mean platelet volume is a strong, independent prognostic factor in PCI-treated patients with DM and SCAD.

RESUMO

QUALITY PROBLEM OR ISSUE: Chinese medical institutions need clinical guidelines to improve healthcare quality. Unfamiliarity with clinical methodology and procedures leads to poor quality. INITIAL ASSESSMENT: This study examined 327 clinical guidelines made in China during the period of 2006-10 and found these clinical guidelines have many problems in terms of guideline making procedures-compliant process, conflicts of interest disclosure. CHOICE OF SOLUTION: Chinese Medical Association organized a working group in 2014 to make a national [Guideline for Clinical Guidelines Constitution/Amendment] and invited multidiscipline experts to prove its possibility. IMPLEMENTATION: Experts investigated and reviewed numerous domestic and foreign published literature within the past 2 years, concluded that a clinical guideline should have following seven components: I. Objective; II. General Principle; III. Procedure and Methodology; IV. Confirmation, Publication and Dissemination; V. Update and Amendment; VI. Implementation and Outcome Validation; VII. Reference. EVALUATION: The [Guideline for Clinical Guidelines Constitution/Amendment] will improve the quality of Chinese clinical guidelines and regulate applications, as well as outcome evaluations of clinical guidelines in China. LESSONS LEARNED: Standardized methodology and procedures are important for constituting high-quality clinical guidelines.

RESUMO

OBJECTIVE: The aim of this study is to establish whether cyclin-dependent kinase inhibitor 2B antisense RNA 1 (CDKN2B-AS1) gene polymorphisms are associated with premature triple-vessel disease (PTVD). METHODS: Nine single-nucleotide polymorphisms (rs1063192, rs10757274, rs1333042, rs1333049, rs2285327, rs3217986, rs3217992, rs4977574, and rs9632884) were genotyped in 884 PTVD patients and 907 control subjects (males ⪕ 50 years old and females ⪕ 60 years old) using the improved multiplex ligase detection reaction method. RESULTS: The allele frequencies of rs10757274 G, rs1333049 C, rs4977574 G (all P < 0.001), and rs3217986 G (P = 0.040) were significantly higher in the PTVD group than in the control group, but those of rs1063192 A, rs1333042 G, and rs9632884 C (all P < 0.001) were significantly lower in the former than in the latter. Logistic regression analysis revealed that homozygote AA of rs1333042 is associated with decreased risk for PTVD (OR = 0.42, 95% CI: 0.22-0.82, P = 0.011). In addition, the allele frequencies observed differed between genders. The G allele of rs3217986 was associated with increased risk for PTVD in male patients only (OR = 2.94, 95% CI: 1.27-6.80, P = 0.012) in the dominant model, and no positively mutated allele was found in female patients. CONCLUSION: Polymorphisms of the CDKN2B-AS1 gene are associated with the incidence of PTVD in the Chinese population. Furthermore, the frequencies of mutated alleles differed between genders.

RESUMO

Background: The patterns of nonadherence to antiplatelet regimen in stented patients (PARIS) thrombotic risk score are a novel score for predicting the risk of coronary thrombotic events (CTEs) after percutaneous coronary intervention (PCI) with drug-eluting stents. However, the prognostic value of this score has not been fully evaluated in non-Euro-American PCI populations. Methods: We performed a prospective, observational study of 10,724 patients who underwent PCI in Fuwai hospital, China and evaluated the PARIS thrombotic risk score's predictive value of CTEs in the PCI population. The area under the receiver operating characteristic curve (AUROC) was used to assess the predictive value of the PARIS score for CTE. Results: Among 9782 patients without in-hospital events, a total of 95 CTEs occurred during the 2-year follow-up. The PARIS score was significantly higher in patients with CTEs (3.38 ± 2.04) compared with patients without events (2.53 ± 1.70, P < 0.001). According to the risk stratification of the PARIS thrombotic score, the risk of CTEs in the high-risk group was 3.14 times higher than that in the low-risk group (hazard ratio [HR], 3.14; 95% confidence interval [CI], 1.92-5.13; P < 0.001). However, the risk of CTEs in the intermediate-risk and low-risk groups was not significant (HR, 1.39; 95% CI, [0.86-2.24]; P = 0.184). The PARIS score showed prognostic value in evaluating CTEs in the overall population (AUROC, 0.621; 95% CI, 0.561-0.681), the acute coronary syndrome (ACS) population (AUROC, 0.617; 95% CI, 0.534-0.700; P = 0.003), and the non-ACS population (AUROC, 0.647; 95% CI, 0.558-0.736; P = 0.001). Conclusions: In a real-world Chinese population, the PARIS thrombotic risk score shows a modest prognostic value for CTEs in patients after PCI. This score also has a predictive value for CTEs in the ACS and non-ACS subgroup populations.

RESUMO

We aimed to determine the association of plasma lipoprotein(a) (Lp[a]) with long-term clinical outcomes in patients with chronic kidney disease (CKD) after percutaneous coronary intervention (PCI) in an observational cohort study. Four hundred and twenty-seven consecutive patients with CKD who underwent PCI from January 2013 to December 2013 were included in this study. Patients were divided into 2 groups according to median levels of Lp(a). Outcomes included 2-year risk of major adverse cardiovascular and cerebrovascular events (MACCEs) and bleeding according to Bleeding Academic Research Consortium definitions. Overall, median of Lp(a) in all the patients was 217.8 mg/L. The 2-year MACCE rate across the high Lp(a) and low Lp(a) group was 23.0% versus 15.4% (p = 0.047) and bleeding event rate of the two groups 8.9% versus 4.2% (p = 0.049). The Lp(a) was significantly and positively correlated with high-sensitivity C-reactive protein levels (r2 = 0.03, p < 0.001). Kaplan-Meier curves revealed that high Lp(a) had higher incidence of bleeding than low Lp(a) (p = 0.043) and had higher risk of MACCE (p = 0.049). Multivariable Cox regression analysis indicated that high Lp(a) was an independent predictor of Bleeding Academic Research Consortium bleeding compared with low Lp(a) (hazard ratios 2.29, 95% confidence intervals 1.01 to 5.15, p = 0.046). In conclusion, a high Lp(a) value may be associated with a poor prognosis after PCI for patients with CKD.

RESUMO

Objective: Small coronary vessel disease (disease affecting coronary vessels with main branch diameters of ≤ 2.75 mm) is a common and intractable problem in percutaneous coronary intervention (PCI). This study was designed to test the theory that the effectiveness and safety of drug-eluting balloons for the treatment of de novo lesions in small coronary vessels are non-inferior to those of drug-eluting stents. Methods: We designed a prospective, multicenter, randomized, controlled clinical trial aiming to assess the effectiveness and safety of the RESTORE® (Cardionovum, Bonn, Germany) drug-eluting balloon (DEB) versus the RESOLUTE® (Medtronic, USA) drug-eluting stent (DES) in the treatment of small coronary vessel disease. This trial started in August 2016. A total of 230 patients with a reference vessel diameter (RVD) ≥ 2.25 mm and ≤ 2.75 mm were randomly assigned to treatment with a DEB or a DES at a 1:1 ratio. The study was also designed to enroll 30 patients with an RVD ≥ 2.00 mm and ≤ 2.25 mm in the tiny vessel cohort. Results: The key baseline data include demographic characteristics, relative medical history, baseline angiographic values and baseline procedural characteristics. The primary endpoint is in-segment diameter stenosis at nine months after the index procedure. Secondary endpoints include acute success, all-cause death, myocardial infarction, target vessel revascularization, target lesion revascularization and stent thrombosis. Conclusions: The study will evaluate the clinical efficacy, angiographic outcomes, and safety of DEBs compared to DESs in the treatment of de novo coronary artery lesions in small vessels.

RESUMO

BACKGROUND: To improve outcomes in patients with diabetes mellitus (DM) undergoing percutaneous coronary intervention remain an unmet clinical need. The study aimed to evaluate the efficacy and safety of G2-DESs and BP-DESs in patients with and without DM in a single center in China. METHODS: A total of 7666 consecutive patients who exclusively had G2-DES or BP-DES implantation throughout 2013 in our center were studied. The primary efficacy endpoint was any target lesion revascularization (TLR), whereas the primary safety endpoint was a composite of death or myocardial infarction (MI) at 2-year follow-up. RESULTS: G2-DESs had a similar occurrence of death, non-fatal MI, TLR, stroke, and stent thrombosis compared with BP-DESs in patients with DM (all P > 0.05). The incidence of TVR and TLR was lower for G2-DESs than for BP-DESs in patients without DM (3.2% vs. 5.1%, P = 0.002; 2.2% vs. 4.5%, P < 0.001, respectively). Kaplan-Meier analysis also showed better TVR- and TLR-free survival rates for G2-DESs than for BP-DESs in patients without DM. Multivariate analysis showed that a BP-DES was an independent risk factor for TLR (hazard ratio 1.963, 95% confidence interval 1.390-2.772, P < 0.001) in patients without DM, which was not predictive of other components of major adverse cardiac events (P > 0.05). CONCLUSIONS: G2-DESs have better efficacy, represented by a reduced risk of TLR, and similar safety compared with BP-DESs in patients without DM. G2-DESs have similar efficacy and safety compared with BP-DESs in patients with DM at 2-year follow-up.

RESUMO

Background: Mounts of studies have shown that low estimated glomerular filtration rate (eGFR) is associated with increased risk of adverse outcomes in patients with coronary artery disease. 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-1·1.73 m-2> eGFR ≥90 ml·min-1·1.73m-2), 18.3% (86/469) in Group 3 (90 ml·min-1·1.73 m-2> eGFR ≥60 ml·min-1·1.73 m-2), 21.8% (26/119) in Group 4 (60 ml·min-1·1.73 m-2> eGFR ≥30 ml·min-1·1.73 m-2), and 40.0% (4/10) in Group 5 (eGFR <30 ml·min-1·1.73 m-2), with statistical significance (χ2 = 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 of eGFR ≥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 (χ2 = 16.26, P = 0.009 at 6-month follow-up, and χ2 = 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 of eGFR might be associated with increased risk of CI-AKI in patients with emergency PCI, implying for future studies and risk stratification in clinical practice.

RESUMO

The time trends regarding the etiology of renal artery stenosis (RAS) are changing, but few investigations have focused on these issues. This study aimed to analyze the time trends regarding the etiology of RAS in a large patient sample from the China Center for Cardiovascular Disease. Consecutive inpatients with RAS from January 1999 to December 2016 were enrolled in this study. The etiologic diagnosis of RAS was based on established criteria. We retrospectively analyzed the time trends regarding the etiology of RAS during an 18-year period. A total of 2905 patients with RAS were enrolled. There were 2393 (82.4%) patients with atherosclerosis (AS), 345 (11.9%) with Takayasu arteritis (TA), 126 (4.3%) with fibromuscular dysplasia (FMD), and 41 (1.4%) with other causes. Among all patients (n = 2905), patients aged ≤ 40 years (n = 450), patients aged >40 years (n = 2455), female patients (n = 1097), male patients (n = 1808), female patients aged >40 years (n = 808), and male patients aged >40 years (n = 1647), there were a gradual increase in the proportion of atherosclerotic RAS (P < 0.05), a gradual decrease in the proportion of RAS caused by TA (P < 0.05), and almost no change in the proportion of RAS caused by FMD during the 18-year period (P > 0.05). The data show that the primary causes of RAS are AS, TA, and FMD. The proportion of RAS caused by AS and TA gradually increased and decreased, respectively, over time, and the proportion of RAS caused by FMD showed no significant change.

RESUMO

PURPOSE: To compare the nephrotoxic effects of iodixanol and iopamidol in patients undergoing peripheral angiography. METHODS: Patients scheduled for peripheral angiography were randomly assigned to the iodixanol group (n = 463) and iopamidol group (n = 458). The primary endpoint was the incidence of contrast associated acute kidney injury (CA-AKI), which was defined as an increase ≥ 25% or ≥ 44.2 µmol/l (0.5 mg/dl) in serum creatinine (SCr) from baseline within 72 h after receiving contrast media (CM). The secondary endpoints were the mean peak SCr increase within 72 h after receiving CM and major adverse renal events (SCr increased by two times after 30 days, the need for dialysis treatment, rehospitalization for acute renal failure, or kidney-related death) during hospitalization and within 30 day postdischarge. RESULTS: The incidence of CA-AKI did not differ significantly between the iodixanol group and iopamidol group (18.1% vs. 16.8%; p = 0.595). There was no significant difference in the mean peak SCr increase between the iodixanol group and iopamidol group (10.4 ± 13.0 vs. 10.6 ± 14.3 µmol/l, p = 0.919). There were four patients [1 (0.2%) patient in the iodixanol group and 1 (0.7%) patients in the iopamidol group, p = 0.609] with doubling of SCr; no other adverse renal events were observed. CONCLUSIONS: Our data showed that the nephrotoxicity of iodixanol was comparable with that of iopamidol in patients undergoing peripheral angiography.
