残余SYNTAX评分在中国冠心病介入患者中的应用价值研究

目的:经皮冠状动脉介入治疗(PCI)术后残余SYNTAX评分(rSS)可作为临床预后的独立预测因子,也可作为不完全血运重建的量化工具。本研究旨在评估在大样本中国冠心病介入患者中rSS对预后的评估价值。方法:纳入我院2013年度共10 724例PCI患者,排除既往行冠状动脉旁路移植术(CABG)以及本次支架置入术为杂交手术的患者381例,最终纳入10 343例冠心病患者。PCI术前分别计算基线SYNTAX评分(b SS)和rSS。rSS=0定义为完全血运重建,rSS≥1定义为不完全血运重建。临床随访30个月,临床终点事件包括主要不良心血管事件(MACE,全因死亡、心肌梗死和再次血运重建的复合终点)、全因死亡、心原性死亡、心肌梗死、全因死亡/心肌梗死和再次血运重建。结果:PCI术后共有5 050例(48.8%)患者达到完全血运重建(rSS=0)。5 293例不完全血运重建(rSS≥1)的患者中,1≤rSS≤4的患者有1 908例(18.4%),4rSS≤9的患者有1 777例(17.2%),rSS9的患者有1 608例(15.5%)。rSS评分越高的患者合并的临床情况越多,冠状动脉病变越复杂。与完全血运重建相比,不完全血运重建患者的30个月临床终点事件发生率更高,并且随着rSS评分增高,临床终点事件发生率亦增高。通过多因素回归分析,rSS是所有不良终点事件的独立预测因素。结论:不完全血运重建的患者,尤其是rSS9的患者,30个月的临床终点事件率更高,预后更差。rSS是临床预后的独立预测因素。对于中国的PCI患者,rSS是一个很好的量化血运重建程度以及评估预后的工具。

Comparison of multiple risk scores in assessing medium-to long-term clinical outcomes in unstable angina / non-ST-elevation myocardial infarction patients undergoing multi vessel percutaneous coronary intervention: An observational,registry-based study in India

ObjectivePost-revascularization mortality in multivessel coronary artery disease (MVCAD) has been explored via several risk scores. Here, we assessed and compared various risk scores in predicting medium to long-term clinical outcomes in unstable angina/non-ST-elevation myocardial infarction (UA/NSTEMI) patients with MVCAD undergoing percutaneous coronary intervention (PCI).MethodsWe analyzed a cohort of a tertiary care center registry enrolling patients in South India, Kerala, with MVCAD (N = 200) who had undergone PCI between 2010 and 2018. The outcomes evaluated were all-cause mortality and major adverse cardiac events (MACE). The risk scores assessed included SYNTAX score (SS), residual SYNTAX score (rSS), SYNTAX revascularization index (SRI), age, creatinine, and ejection fraction (ACEF) score, clinical SYNTAX score (cSS), and SYNTAX score II (SSII).ResultsOf the analyzed risk scores, SSII had the best predictive capability with the area under the curve (AUC) of 0.79 in c-statistics, followed by ACEF score and cSS with AUCs of 0.74 and 0.65, respectively for all-cause mortality (p < 0.01). Kaplan–Meier survival curves and multivariate analysis by Cox regression showed SSII with cut-offs of >35.15 and > 29.55 to be the only score associated with higher mortality and MACE, respectively.ConclusionsIn UA/NSTEMI patients with relatively less complex MVCAD treated by PCI, the SSII, ACEF and cSS risk scores could predict the outcomes better. The SSII showed the best predictive performance for all-cause mortality and MACE. Scores based on baseline and residual atherosclerotic burden (SS, rSS, and SRI) performed poorly in predicting the mortality and MACE.     

Comparison of the predictive value of EuroSCORE,SYNTAX score,and clinical SYNTAX score for outcomes of patients undergoing percutaneous coronary intervention for unprotected left main coronary artery disease

Objectives : We aimed to assess the prognostic values of the EuroSCORE, SYNTAX score, and the novel Clinical SYNTAX score (CSS) for 30‐day and 1‐year outcomes in patients undergoing left main (LM) percutaneous coronary intervention (PCI). Background : PCI has become an alternative treatment for LM coronary artery disease, and risk scoring system might be beneficial for pre‐PCI risk stratification. Methods and Results : We enrolled 198 consecutive patients with unprotected LM disease undergoing PCI (mean age 71.5 ± 10.7 years). The CSS was calculated by multiplying the SYNTAX Score to (age/left ventricular ejection fraction +1 for each 10 mL the estimated glomerular filtration rate <60 mL/min per 1.73 m²). The endpoints were 30‐day, and 1‐year all‐cause death and major adverse cardiovascular events (MACE), which were defined as all‐cause death, nonfatal MI, and clinical‐driven target vessel revascularization. Comparing with the SYNTAX score, the predictive accuracy of CSS for 30‐day and 1‐year all‐cause death and MACE were significantly higher (c‐statistics, CSS versus SYNTAX score: P < 0.01 for 30‐day and 1‐year all‐cause death; P < 0.05 for 30‐day and 1‐year MACE, respectively). Furthermore, in the multivariate Cox regression analysis, both EuroSCORE and CSS were identified as the independent predictors of 30‐day and 1‐year all‐cause death and MACE, but the SYNTAX score was not. Conclusions : In the general practice among a high‐risk population undergoing LM PCI, EuroSCORE and CSS might be independent predictors for 30‐day and 1‐year all‐cause death and MACE. Furthermore, the CSS had a superior discriminatory ability in predicting the 30‐day and 1‐year clinical outcomes comparing with the SYNTAX score. © 2012 Wiley Periodicals, Inc.     

The Value of the GRACE Score for Predicting the SYNTAX Score in Patients with Unstable Angina/Non-ST Elevation Myocardial Infarction

BackgroundIn patients with unstable angina/non-ST-elevation myocardial infarction (UA/NSTEMI), Global Registry for Acute Coronary Events (GRACE) score is a valid tool for risk stratification. The Synergy between PCI with Taxus and Cardiac Surgery (SYNTAX) score is an angiographic scoring system to guide the decision-making between coronary artery bypass grafting (CABG) surgery and percutaneous coronary intervention (PCI). The aim of the present study was to assess the accuracy of the GRACE score in predicting the severity and extent of coronary artery stenosis by SYNTAX score.MethodsA total of 330 patients with acute coronary syndrome (ACS) were enrolled in the study. For every patient, the GRACE score was calculated. All patients underwent coronary angiography within 2 days and the SYNTAX scoring system was used to evaluate the severity and extent of coronary stenotic lesions. Based on ROC curve analysis, the cut-off value of GRACE score that could predict SYNTAX score ≥ 23 was calculated.ResultsGRACE score was 107.12 ± 34.4 in patients with SYNTAX SCORE < 23 and 134.80 ± 48.3 in patients with SYNTAX score ≥ 23 (p value = 0.001). A positive correlation was observed between the GRACE score and angiographic SYNTAX score (r = 0.34 p < 0.001). We found that a GRACE score of 109 is the optimal cut-off to predict SYNTAX score ≥ 23 with a sensitivity of 73.5% and specificity of 60% (p < 0.001). Its negative predictive value was 94.0%.ConclusionGRACE score had significant but modest value to predict the severity and extent of coronary artery stenosis in patients with ACS.     

Associação entre Escores de Risco Clínico (HEART,GRACE e TIMI) e Complexidade Angiográfica na Síndrome Coronária Aguda sem Elevação do Segmento ST

Background:GRACE, TIMI and HEART scores have been previously validated to predict serious untoward events among patients with non-ST elevation acute coronary syndrome (Non-ST ACS). However, the ability of these scores to discriminate the angiographic complexity of coronary artery disease has not been clearly established.Objectives:We sought to evaluate the correlation between clinical scores (TIMI, GRACE and HEART) and the anatomical complexity assessed by SYNTAX score, among non-ST ACS patients undergoing cinecoronariography.Methods:Transversal cohort encompassing patients with diagnosis of Non-ST ACS referred to invasive stratification in our single center, between July 2018 and February 2019. Association between the scores was established by the Pearson''s linear correlation test while the accuracy of the clinical scores versus SYNTAX score was determined with the ROC curve.Results:A total of 138 patients were enrolled. Median GRACE, TIMI and HEART scores were 97, 3 and 5, respectively, whereas the median SYNTAX was 8. There was a positive correlation between the SYNTAX and the HEART (ρ =0.29; p<0.01) and GRACE (ρ =0.18; p<0.01) scores, but the correlation with TIMI reached no statistical significance (ρ =0.15; p=0.08). The HEART score was also the one with the highest area under the curve to predict a SYNTAX ≥32 [HEART = 0.81 (IC95% 0.7-0.91). HEART> 4 presented 100% sensitivity, with 50% specificity; and GRACE> 139 showed 55% sensitivity and 97% specificity for high SYNTAX.Conclusion:The clinical scores presented a positive, although modest, association with the SYNTAX score. The combined use of HEART and GRACE offers good accuracy for detecting angiographic complexity.

Accuracy of the TIMI and GRACE scores in predicting coronary disease in patients with non-ST-elevation acute coronary syndrome

Introduction

The GRACE and TIMI scores have been well validated for assessment of prognosis in non-ST-elevation acute coronary syndrome (NSTE-ACS). However, their value in predicting coronary artery disease (CAD) has been little studied. We aimed to assess the relationship between these scores and the extent of coronary disease.

Association of Residual Ischemic Disease With Clinical Outcomes After Percutaneous Coronary Intervention

BackgroundAnatomical scoring systems have been used to assess completeness of revascularization but are challenging to apply to large real-world datasets.ObjectivesThe aim of this study was to assess the prevalence of complete revascularization and its association with longitudinal clinical outcomes in the U.S. Department of Veterans Affairs (VA) health care system using an automatically computed anatomic complexity score.MethodsPatients undergoing percutaneous coronary intervention (PCI) between October 1, 2007, and September 30, 2020, were identified, and the burden of prerevascularization and postrevascularization ischemic disease was quantified using the VA SYNTAX (Synergy Between PCI With Taxus and Cardiac Surgery) score. The association between residual VA SYNTAX score and long-term major adverse cardiovascular events (MACE; death, myocardial infarction, repeat revascularization, and stroke) was assessed.ResultsA total of 57,476 veterans underwent PCI during the study period. After adjustment, the highest tertile of residual VA SYNTAX score was associated with increased hazard of MACE (HR: 2.06; 95% CI: 1.98-2.15) and death (HR: 1.50; 95% CI: 1.41-1.59) at 3 years compared to complete revascularization (residual VA SYNTAX score = 0). Hazard of 1- and 3-year MACE increased as a function of residual disease, regardless of baseline disease severity or initial presentation with acute or chronic coronary syndrome.ConclusionsResidual ischemic disease was strongly associated with long-term clinical outcomes in a contemporary national cohort of PCI patients. Automatically computed anatomic complexity scores can be used to assess the longitudinal risk for residual ischemic disease after PCI and may be implemented to improve interventional quality.
