Abstract

Objectives: To identify elements of the HEART score in patients with chest pain. To examine association between the HEART score and coronary events within 6 weeks. Methods: The study included 60 patients with chest pain treated in the emergency department of 199 Hospital, from 8/2018 to 8/2019 based on the descriptive, prospective follow-up study. Results: Prognostic value of the HEART score for the events: The HEART score was proportionally associated with the events. Average points of the HEART score in the group without an event was 3.61 ± 1.88 and in the group with at least 1 event was 6.00 ± 1.45 (p <0.01). Prognostic value of the HEART score for the events in the study group was very high. With the cut-off of ≥ 4 points, the HEART score had prognostic value for the events in the study group with a sensitivity of 84.2% (95% CI: 60.4 to 96.4), a specificity of 68,3 % (95 % CI: 61.9 to 81.9), the area under the ROC curve was 831. Values of the HEART score on risk stratification for the events: In the low-risk group of patients with a HEART score of 0-3 points, incidence of events was 0%. With a HEART score of 4-6 points, 37.5% of the patients had events. With a HEART score of 7-10 points belonging the high risk group, there were up to 77.8% of the patients having events. Probability of not having events among patients with 4-6 points or 1-3 points of the HEART score was higher than that among those with 7-10 point of the score (p<0.001). The HEART score was valuable in risk stratification, prognosis of coronary artery disease events.
