Abstract 【Objective】 To explore the correlation between Coronary Artery Calcium Score (CCS) and the short-term prognosis of patients with Coronary Artery Disease (CAD) after interventional surgery. 【Methods】 A total of 120 patients who underwent coronary artery interventional treatment and coronary artery CT angiography (CTA) were included in the study. CCS was calculated for each patient. Patients were followed up for 6 months outside the hospital to record the occurrence of major adverse cardiac events (MACE) and the survival time without events. Based on those information, patients were divided into two groups: the poor prognosis group (n=27) and the good prognosis group (n=93). The relationship and predictive value of CCS in patients with their prognosis were analyzed. 【Results】 The age, CCS, serum creatinine (Scr), and N-terminal pro-brain natriuretic peptide (NT-proBNP) levels in the poor prognosis group were significantly higher than those in the good prognosis group (P<0.05). The time without MACE and Left Ventricular Ejection Fraction (LVEF) were significantly lower in the poor prognosis group compared to the good prognosis group (P<0.05).CCS showed a positive correlation with age (r=0.518, P<0.05) and Scr (r=0.407, P<0.05), and a negative correlation with LVEF (r=-0.215, P<0.05).The area under the curve (AUC) of the receiver operating characteristic (ROC) curve for predicting MACE using CCS was 0.84(95%CI: 0.76-0.92).CCS, LVEF, and NT-proBNP were correlated with poor prognosis in patients, with odds ratios (OR) (95%CI) of 1.46 (0.61-3.49), 1.01 (0.98-1.05), and 1.24 (1.03-1.82), respectively. 【Conclusion】 CCS is an independent risk factor for poor short-term prognosis in patients undergoing interventional treatment for CAD and is a potential clinical indicator for assessing MACE.
