ABSTRACT
Objective:To evaluate the effect of coronary artery anatomical score(SYNTAX score) on in-hospital mortality of CABG patients.Methods:The clinical data of patients who were performed with a CABG surgery alone in the Department of Cardiovascular Surgery, Tianjin Chest Hospital from July 2017 to December 2018 were collected. The clinical end point was all-cause in-hospital death or against-advice discharge after surgery. Univariate analysis and multivariate logistic regression analysis were performed on the clinical data of the patients to obtain the risk factors affecting the in-hospital death of CABG in our center, to evaluate the influence of SYNTAX score on the in-hospital death of CABG. Results:Univariate logistic analysis showed that age, critical condition, creatinine level, serum albumin level, NT-proBNP level, NYHA grade, internal mammary artery use, SYNTAX score were correlated with in-hospital mortality. Multivariate analysis showed that age(≥75 years old), history of diabetes mellitus, critical state, creatinine clearance rate < 85 ml/min, albumin <35 g/L, NYHA Ⅲ-Ⅳ, SYNTAX score(≥29) were independent risk factors for in-hospital mortality after CABG. Conclusion:Coronary artery anatomy score - SYNTAX score(≥29) was an independent risk factor for in-hospital mortality in CABG patients in our hospital.
