Abstract:

Objective To investigate the correlation between systemic immune inflammation (SII) index and severity of coronary artery disease in patients with acute coronary syndrome (ACS). Methods A total of 206 ACS patients with typical symptoms of chest pain and chest tightness underwent coronary angiography in the Department of Cardiology of Anshan Central Hospital from September 2021 to March 2023 were enrolled. The clinical data and the immune inflammation indexes were assessed. According to the coronary angiography results or the modified Gensini score, the patients were divided into single-vessel disease group (n=51) and multi-vessel disease group (n=155), or mild lesion group (n=89) and advanced lesion group (n=117). The inter-group differences in clinical data were compared, and the independent risk factors for severity of coronary artery disease were screened for evaluating their predictive value. Results The area under the curve of SII in predicting severity of coronary artery disease in ACS patients was 0.93. When SII was 631.31, the predictive ability for severity of coronary artery disease in ACS patients was the highest, with 81.9% of the sensitivity and 96.1% of specificity. Conclusion SII is an independent risk factor for severity of coronary artery disease in ACS patients, and it has a high predictive value.
