Abstract

Objective

We aimed to investigate the relationship between baselıne SYNTAX score (bSS) and residual SS (rSS) and in-hospital adverse major cardiovascular events (death, cerebrovascular events, etc.) in patients with diabetes mellitus (DM) who underwent percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS).

Material and Methods

Between 1 June 2018 and 30 June 2019, 352 patients with DM who were hospitalised for ACS (ST elevation myocardial infarction, non-ST elevation myocardial infarction and unstable angina pectoris) and underwent PCI were included in our study. Demographic information, clinical history, epicrisis, laboratory-imaging results and recorded angiographic images of the selected patient group were obtained from the hospital electronic database system and patient files. bSS and rSS were calculated from the coronary angiography images of the patients recorded via the hospital electronic environment. In-hospital adverse events of the patients were recorded. Statistics were performed for the relationship between these recorded data and the calculated bSS and rSS and the data were transferred to the study.

Results

Insulin use and cardiac mortality were significantly associated with higher SS in diabetic patients. In univariate logistic regression analysis, bSS and rSS were statistically significant in predicting in-hospital mortality. In multivariate logistic regression analysis, bSS was significant in predicting in-hospital mortality, while rSS was not significant.

Conclusion

bSS and rSS can predict some of the in-hospital outcomes. High SS (bSS, p<0.001) was found to be significantly associated with the prediction of in-patient mortality.
