Abstract

Purpose: Chest pain in a common symptom in patients attending Emergency Department worldwide and can be related to an extensive variety of disorders, so it represents a diagnostic and logistic challenge for Emergency physicians. The aim of this study is to identify a subgroup of patients with a low pre-test probability of major adverse cardiac events, for which there is no need of troponin testing, to avoid potential harm from false-positive testing and long length stay in ED.

Patients and methods: We retrospectively analyzed data of patients that attended ED of Siena complaining chest pain from January 2019 to August 2021. We used a modified HEART score, only evaluating history, EKG, age and risk factors. A 0-1 HEAR score was considered at very low risk for adverse cardiac events. Sensitivity, specificity, PPV, NPV and incidence of adverse cardiac events were calculated. The accuracy of HEAR score was evaluated with ROC curve. The correlation of adverse cardiac events with HEAR score 0-1 was evaluated with Fisher test.

Results: In this study, we included 2046 patients, of which 279 were classified at very low risk. The incidence of adverse cardiac events in this population was 0.36%. Sensibility was 97.5%, sensitivity 61%, PPV 36.8%, NPV 99.1%. The AUC for global accuracy of HEAR score was 0.945. Chi-square's P value for the association between adverse cardiac events and HEAR score 0-1 was <0.001.

Conclusion: The draft presented in this study answers to the necessity to make a personalized path for patients attending ED with chest pain. The choice to avoid troponin testing may appear risky, but data from this study and from other similar show that a careful evaluation of clinical data and EKG allows to correctly discriminate which patients will not have adverse cardiac events, reducing the length of stay in ED.

Keywords: HEAR score; chest pain; electrocardiogram; emergency medicine; troponin.
