RESUMO
Resumo Fundamento A estratificação de risco precoce com biomarcadores simples é essencial em pacientes com infarto do miocárdio sem supradesnivelamento do segmento ST (IAMSSST). Objetivo Este estudo tem o objetivo de avaliar a associação entre nível de big endotelina-1 plasmática (ET-1) e o escore SYNTAX (SS) em pacientes com IAMSSST. Métodos Foram recrutados 766 pacientes com IAMSSST que passaram por angiografia coronária. Os pacientes foram divididos em três grupos SS baixo (≤22), SS intermediário (23-32), e SS alto (>32). A correlação de Spearman, o ajuste de curva suave, a regressão logística, e a análise de curva característica de operação do receptor (ROC) foram realizados para avaliar a associação entre o nível de big ET-1 plasmática e o SS. Um p-valor <0.05 foi considerado estatisticamente significativo. Resultados Foi identificada uma correlação significativa entre a big ET-1 e o SS (r=0,378, p<0,001). A curva suavizada indicou uma correlação positiva entre o nível de big ET-1 plasmática e o SS. A análise de curva ROC demonstrou que a área sob a curva foi de 0,695 (0,661-0,727) e o ponto de corte ideal do nível de big ET-1 plasmática foi de 0,35 pmol/l. A regressão logística demonstrou que a big ET-1 elevada era um preditor independente de SS intermediário a alto em pacientes com IAMSSST, seja como variável contínua [RC (IC 95% 1,110 (1,053-1,170), p<0,001] ou como variável categórica [RC (IC 95% 2,962 (2,073-4,233), p<0,001]. Conclusão Em pacientes com IAMSSST, o nível de big ET-1 plasmática estava significativamente correlacionado ao SS. O nível de big ET-1 plasmática elevado foi um preditor independente para SS intermediário a alto.
ABSTRACT
Abstract Background Early risk stratification with simple biomarkers is essential in patients with non-ST segment-elevation myocardial infarction (NSTEMI). Objective This study aimed to evaluate the association between plasma big endothelin-1 (ET-1) level and the SYNTAX score (SS) in patients with NSTEMI. Methods A total of 766 patients with NSTEMI undergoing coronary angiography were recruited. Patients were divided into three groups low SS (≤22), intermediate SS (23-32), and high SS (>32). Spearman correlation, smooth curve fitting, logistic regression, and receiver operating characteristic (ROC) curve analysis were performed to evaluate the association between plasma big ET-1 level and the SS. A p-value <0.05 was considered statistically significant. Results There was a significant correlation between the big ET-1 and the SS (r=0.378, p<0.001). The smoothing curve indicated a positive correlation between the plasma big ET-1 level and the SS. The ROC curve analysis showed that the area under the curve was 0.695 (0.661-0.727) and the optimal cutoff of plasma big ET-1 level was 0.35pmol/l. Logistic regression showed that elevated big ET-1 was an independent predictor of intermediate-high SS in patients with NSTEMI, whether entered as a continuous variable [OR (95% CI) 1.110 (1.053-1.170), p<0.001] or as a categorical variable [OR (95% CI) 2.962 (2.073-4.233), p<0.001]. Conclusion In patients with NSTEMI, the plasma big ET-1 level was significantly correlated with the SS. Elevated plasma big ET-1 level was an independent predictor for intermediate-high SS.
