Giá trị dự báo biến cố tim mạch chính của thang điểm CHA2DS2-VASc ở bệnh nhân hội chứng vành cấp có can thiệp động mạch vành qua da tại Bệnh viện Đa khoa Trung ương Cần Thơ

The CHA2DS2-VASc score has mainly been used to predict the risk of embolic stroke in patients with nonvalvular atrial fibrillation. There has been a lot of research in the world which proved that the CHA2DS2-VASc scoring system could be used for risk stratification in patients with acute coronary syndrome. Objective: To investigate the rate of major adverse cardiovascular events and the value of the CHA2DS2-VASc score in predicting cardiovascular events in patients with acute coronary syndrome undergoing percutaneous coronary intervention. Materials and methods: Patients were diagnosed with acute coronary syndrome undergoing coronary angiography and percutaneous coronary intervention at Can Tho Central General Hospital. The method was a crosssectional study with analysis. Results: During 6 months of follow-up after percutaneous coronary intervention, major adverse cardiovascular events occurred in 8.3% of patients. The area under the ROC curve for the CHA2DS2-VASc score in predicting major adverse cardiovascular events was 0.825 (p=0.001). A cut-off value of ≥4 had a sensitivity of 70% and a specificity of 80.9%. A Kaplan-Meier analysis of CHA2DS2-VASc scores of ≥4 showed a higher rate of adverse events as compared with scores of <4 (log-rank test, p<0.001). Conclusion: The CHA2DS2-VASc score is useful for the prediction of cardiovascular events in acute coronary syndrome patients undergoing percutaneous coronary intervention.
