A prospective study of the HEART scores' value in diagnosing acute coronary syndrome in the chest pain center / 中华急诊医学杂志

ABSTRACT

Objective To study the value of HEART scores in predicting the risk of getting acute coronary syndrome in patients with chest pain and assessing the prognosis in order to elucidate the validity of the HEART scores.Methods A total of 1 200 patients with chest pain were continuously observed and followed up,and their HEART scores were calculated.The survival rates were calculated with Kaplan-Meier method and AUROC (area under ROC curve) was used to determine the accuracy of this methods.The HEART scores were compared with TIMI and GRACE scores.Results Low HEART scores (0-3) were found in 34.5％ of the patients and MACE (major adverse cardiac event) occurred in 1.4％ of them.The patients with intermediate HEART scores (4-6) accounted for 50.7％ patients,and MACE was diagnosed in 22.2％ of them.High HEART scores (7-10) were found in 14.85％ patients,and MACE occurred in 60.7％ of them.There was significant difference among these three groups (Log rank P ＜ 0.01).The AUROC of HEART score was 0.83 (95％ CI0.80-0.85,P ＜0.01),being significantly higher than the GRACE scores (0.76) and TIMI scores (0.72).Conclusions The HEART score is applicable for predicting the risk of getting acute coronary syndrome of chest pain patients in emergency department and the prognosis.
