Nghiên cứu giá trị thang điểm CHIP trong phân tầng nguy cơ ở bệnh nhân tổn thương động mạch vành phức tạp nguy cơ cao được can thiệp động mạch vành

Abstract

Objective: To evaluate the predictive value of the CHIP score for major cardiovascular events and mortality in patients having coronary intervention who have high-risk complicated coronary artery lesions, one year after the intervention. Subject and method: Cross-sectional descriptive study on 56 patients with chronic coronary syndrome and complex and high-risk non-ST-segment elevation acute coronary syndrome undergoing percutaneous coronary intervention from March 2021-August 2021. Evaluate the CHIP score with 4 criteria: Age > 80 (3 points), dialysis (6 points), left ventricular ejection fraction < 30% (2 points), and number of treated lesions >2 (2 points). There are three categories of scoring: low risk (0 points), medium risk (2–3), and high risk (≥4). The overall score is 13 points. Evaluate the prognosis of major cardiovascular events and mortality in the hospital and 1 year after discharge. Result: CHIP score had good predictive value for death and in-hospital major cardiovascular events (AUC = 0.98 and CI: 0.95-1.0), equivalent to Syntax and Syntax 2 scores; moderate prognosis of death 1 year after intervention (AUC = 0.74 and CI: 0.49-1.0), equivalent to Syntax score and Syntax 2 score; moderate predictive value for major cardiovascular events 1 year after intervention (AUC = 0.74 and CI: 0.61–0.89), better than the Syntax score and equivalent to the Syntax 2 score. Conclusion: In patients with complex and high-risk chronic coronary syndrome and non-ST-segment elevation acute coronary syndrome undergoing percutaneous coronary intervention, the CHIP score exhibited predictive value for in-hospital mortality and major cardiovascular events one year after discharge.
