Assessing risk of major adverse cardiac event among COVID-19 patients using HEART score.

Abstract

Coronavirus disease 2019 (COVID-19) is known to be associated with cardiovascular complications, but whether the current validated HEART score for chest pain is still applicable for these patients is unknown. This study aims to identify the impact and association of COVID-19 co-infection in patients presenting with chest pain and a calculated HEART score to the emergency departments (ED) with 30-day of major adverse cardiac event (MACE). This is a multicenter, retrospective observational study that included adult (age ≥ 18years) patients visiting 13 different EDs with chest pain and evaluated using a HEART score. The primary outcome was the percentage of 30-day MACE, which included acute myocardial infarction, emergency percutaneous coronary intervention (PCI), coronary artery bypass graft (CABG), or death among patients who presented with chest pain and had COVID-19 co-infection. The sensitivity and specificity of the HEART score among COVID-19 co-infection for MACE were assessed by the receiver operating curve (ROC). We analyzed records of 46,210 eligible patients, in which 327 (0.7%) patients were identified as infected with COVID-19. Patients with COVID-19 had higher mean total HEART score of 3.3 (1.7), compared to patients who did not have COVID-19 (3.1, SD 1.8, P = 0.048). The rate of MACE was similar between both groups. There were only 2 (0.6%) COVID-19 patients who had MACE, compared to 504 (1.1%) patients in control group. Total HEART score was associated with an area under the ROC (AUROC) of 0.99, while the control group's was 0.78. History was associated with high AUROC in both COVID-19 (0.74) and control groups (0.76). Older age in COVID-19 had higher AUROC (0.89) than control patients (0.63). Among patients presenting to the ED with chest pain and having COVID-19 infection, HEART score had predictive capability for MACE, similar to patients without COVID-19 infection. Further studies with more COVID-19 patients are still necessary to confirm our observation.
