Prognostic value of C-ACS risk score for no reflow or slow flow in patients with STEMI after PCI
Objective To evaluate the prognostic value of Canada Acute Coronary Syndrome(C-ACS)risk score for no reflow or slow flow in patients with ST-segment elevation myocardial infarction(STEMI)after percutaneous coronary intervention(PCI).Methods One hundred and twenty-one patients diagnosed with STEMI who received PCI in No.215 Hospital of Shaanxi Nuclear Industry from January 2022 to April 2023 were included.There were 87 males and 34 females,with an average age of 67.4 years old.The patients were divided into two groups according to whether combined with no-reflow/slow flow,and the clinical data of the two groups were compared.Logistic regression analysis was used to find the influencing factors of no reflow/slow flow in STEMI patients after PCI.The receiver operating characteristic curve(ROC)was used to evaluate the predictive value of C-ACS risk score for no reflow/slow flow in STEMI patients after PCI.Independent sample t test and x2 test were used.Results Age,male,smoking,serum creatinine level,Global Registry of Acute Coronary Events(GRACE)score,and C-ACS risk score in the no-reflow/slow flow group were significantly higher than those in the normal flow group,with statistically significant differences(all P＜0.05).Logistic regression analysis showed that age,GRACE score,C-ACS risk score,male,and smoking were all risk factors for no-reflow/slow flow in STEMI patients after PCI(all P＜0.05).The sensitivity,specificity,and area under the curve(AUC)of C-ACS risk score for predicting no-reflow/slow flow in STEMI patients after PCI were 72.9％,75.3％,and 0.783;the sensitivity,specificity,and AUC of C-ACS risk score combined with GRACE score in predicting no-reflow/slow flow in STEMI patients after PCI were 70.8％,86.3％,and 0.844.The specificity and AUC of C-ACS risk score combined with GRACE score in predicting no-reflow/slow flow in STEMI patients after PCI were higher than those of single indicator.Conclusions C-ACS risk score has a high predictive value for no-reflow/slow flow in STEMI patients after PCI.The C-ACS risk score combined with GRACE score has a higher specificity in predicting no reflow/slow flow in STEMI patients after PCI.
