HEART-score can be simplified without loss of discriminatory power in patients with chest pain - Introducing the HET-score
The American journal of emergency medicine(2023)
摘要
Background: The History, Electrocardiogram (ECG), Age, Risk factors and Troponin, (HEART) score is useful for early risk stratification in chest pain patients. The aim was to validate previous findings that a simplified score using history, ECG and troponin (HET-score) has similar ability to stratify risk.Methods: Patients presenting with chest pain with duration of >= 10 min and an onset of last episode <= 12 h but without ST-segment elevation on ECG at 6 emergency departments were eligible for inclusion. The HEART-score and the simplified HET-score were calculated. The endpoint was a composite of myocardial infarction (MI) as index diagnosis, readmission due to new MI or death within 30 days.Results: HEART-score identified 32% as low risk (0-2p), 47% as intermediate risk (3-5p), and 20% as high risk (6-10p) patients. The endpoint occurred in 0.5%, 7.3% and 35.7%, respectively. HET-score identified 39%, 42% and 19% as low-(0p), intermediate-(1-2p) and high-risk (3-6p) patients, with the endpoint occurring in 0.6%, 6.2% and 43.2%, respectively. When all variables included in the HEART-score were included in a multivariable logistic regression analysis, only History (OR, CI [95%]): 2.97(2.16-4.09), ECG (1.61[1.14-2.28]) and troponin level (5.21[3.91-6.95]) were significantly associated with cardiovascular events. When HEART-and HET-score were compared in a ROC-analysis, HET-score had a significantly larger AUC (0.887 vs 0.853, p < 0.001).Conclusions: Compared with HEART-score, HET-score is simpler and appears to have similar ability to discriminate between chest pain patients with and without cardiovascular event.(c) 2023 Published by Elsevier Inc.
