Abstract

BACKGROUND

: The importance of coronary anatomy in predicting cardiovascular events is well known. The use of traditional anatomical scores in routine angiography, however, has not been incorporated to clinical practice. SYNTAX score (SXscore) is a scoring system that estimates the anatomical extent of coronary artery disease (CAD). Its ability to predict outcomes based on a baseline diagnostic angiography has not been tested to date.

OBJECTIVE

: To evaluate the performance of the SXscore in predicting major adverse cardiac events (MACE) in patients referred for diagnostic angiography.

METHODS

: Prospective cohort of 895 patients with suspected CAD referred for elective diagnostic coronary angiography from 2008 to 2011, at a university-affiliated hospital in Brazil. They had their SXscores calculated and were stratified in three categories: no significant CAD (n = 495), SXscoreLOW-INTERMEDIATE: < 23 (n = 346), and SXscoreHIGH: ≥ 23 (n = 54). Primary outcome was a composite of cardiac death, myocardial infarction, and late revascularization. Secondary endpoints were the components of MACE and death from any cause.

RESULTS

: On average, patients were followed up for 1.8 ± 1.4 years. The primary outcome occurred in 2.2%, 15.3%, and 20.4% in groups with no significant CAD, SXscoreLOW-INTERMEDIATE, and SXscoreHIGH, respectively (p < 0.001). All-cause death was significantly higher in the SXscoreHIGH compared with the 'no significant CAD' group, 16.7% and 3.8% (p < 0.001), respectively. After adjustment for confounding factors, all outcomes remained associated with the SXscore.

CONCLUSIONS

: SXscore independently predicts MACE in patients submitted to diagnostic coronary angiography. Its routine use in this setting could identify patients with worse prognosis.

FUNDAMENTO

: A importância da anatomia coronariana na predição de eventos cardiovasculares é bem conhecida. O uso de escores anatômicos tradicionais na cineangiocoronariografia de rotina, entretanto, não foi incorporado à prática clínica. O SYNTAX escore (SXescore) é um sistema de escore que estima a extensão anatômica da doença arterial coronariana (DAC). Sua capacidade para predizer desfechos com base na cineangiocoronariografia diagnóstica de base ainda não foi testada.

OBJETIVO

: Avaliar o desempenho do SXescore para predizer eventos cardíacos adversos maiores (MACE) em pacientes encaminhados para cineangiocoronariografia diagnóstica.

MÉTODOS:: Coorte prospectiva de 895 pacientes com suspeita de DAC encaminhados para cineangiocoronariografia diagnóstica eletiva de 2008 a 2011, em hospital universitário no Brasil. Os pacientes tiveram seus SXescores calculados e foram estratificados em três categorias: 'sem DAC significativa' (n = 495); SXescoreBAIXO-INTERMEDIÁRIO: < 23 (n = 346); e SXescoreALTO: ≥ 23 (n = 54). O desfecho primário foi composto de morte cardíaca, infarto do miocárdio e revascularização tardia. Os desfechos secundários foram MACE e morte por todas as causas.

RESULTADOS

: Em média, os pacientes foram acompanhados por 1,8 ± 1,4 anos. Desfecho primário ocorreu em 2,2%, 15,3% e 20,4% nos grupos 'sem DAC significativa', SXescoreBAIXO-INTERMEDIÁRIO e SXescoreALTO, respectivamente (p < 0,001). Morte por todas as causas foi significativamente mais frequente no grupo de SXescoreALTO comparado ao grupo 'sem DAC significativa', 16,7% e 3,8% (p < 0,001), respectivamente. Após ajuste para fatores de confusão, todos os desfechos permaneceram associados com o SXescore.

CONCLUSÃO:: O SXescore prediz independentemente MACE em pacientes submetidos a cineangiocoronariografia diagnóstica. Seu uso rotineiro nesse contexto poderia identificar pacientes de pior prognóstico.

摘要

背景

冠状动脉解剖结构在预测心血管事件中的重要性已广为人知。然而,传统解剖学评分在常规血管造影中的应用尚未纳入临床实践。SYNTAX评分(SXscore)是一种评估冠状动脉疾病(CAD)解剖范围的评分系统。其基于基线诊断性血管造影预测预后的能力迄今尚未得到验证。

目的

评估SXscore在预测接受诊断性血管造影患者的主要不良心脏事件(MACE)中的性能。

方法

对2008年至2011年在巴西一家大学附属医院因疑似CAD接受择期诊断性冠状动脉造影的895例患者进行前瞻性队列研究。计算他们的SXscore,并将其分为三类:无显著CAD(n = 495)、SXscore低-中度:<23(n = 346)和SXscore高:≥23(n = 54)。主要结局是心脏死亡、心肌梗死和晚期血运重建的复合终点。次要终点是MACE的组成部分和任何原因导致的死亡。

结果

平均随访患者1.8±1.4年。无显著CAD组、SXscore低-中度组和SXscore高组的主要结局发生率分别为2.2%、15.3%和20.4%(p<0.001)。SXscore高组的全因死亡率显著高于“无显著CAD”组,分别为16.7%和3.8%(p<0.001)。在对混杂因素进行调整后,所有结局仍与SXscore相关。

结论

SXscore可独立预测接受诊断性冠状动脉造影患者的MACE。在这种情况下常规使用SXscore可识别预后较差的患者。
