Comparison of HEART and GRACE scores for 30-day predictive value in patients with acute chest pain in emergency department / 中华急诊医学杂志

ABSTRACT

Objective To evaluate the predictive value of HEART and GRACE scores for risk stratification and 30-day major adverse cardiovascular events (MACE) in patients with acute chest pain in emergency department.Methods This is a prospective observational study.Patients with acute chest pain aged 18 years or older who were first diagnosed in our emergency department were enrolled from January 1,2016 to September 1,2017.The clinical data were collected,and HEART and GRACE scores were calculated.All causes of MACE in each patient were followed up for 30 days.Results This study included 1004 patients with acute chest pain for analysis.Finally this study enrolled 600 patients with an age range of 20-98 years (mean 63.28±15.47 years),351 males (58.5％) and 249 females (41.5％).The age,past history (smoking,coronary heart disease and diabetes),GRACE score and HEART score in MACE patients were significantly higher than those in non-MACE patients (P＜0.05).The area under the ROC curve of HEART and GRACE scores were 0.817 (95％ CI 0.771-0.863) and 0.739 (95％ CI:0.687-0.791),respectively.The percent of patients with 30-day MACE with GRACE score and HEART score were 6.2％ vs 4.1％ in low-risk stratification,19.7％ vs 15.1％ in medium-risk stratification,and 35.1％ vs 56.5％ in high-risk stratification,respectively.Conclusions The HEART score is superior to the GRACE score in predicting 30-day MACE in patients with acute chest pain in emergency department.
