Prognostic value of in-hospital and 6-month mortality after acute coronary syndrome using GRACE, TIMI, and HEART scores

Abstract

BackgroundPrognostic assessment of early cardiovascular events in patients with acute coronary syndrome (ACS) can be aided by the HEART, TIMI, and GRACE scores. However, their combined use has not been extensively researched. ObjectivesDetermining the prognostic value of in-hospital and 6-month mortality using the GRACE, TIMI, and HEART scores in patients with acute coronary syndrome. MethodsWe conducted a cross-sectional descriptive study on 68 patients with acute coronary syndrome, following them longitudinally for 6 months at Can Tho Central General Hospital, Vietnam. ResultsThe GRACE score demonstrated good prognostic value for in-hospital mortality, with an area under the curve (AUC) of 0.805. Sensitivity and specificity were 90% and 65.51%. Conversely, the TIMI risk score had a poor prognostic value for in-hospital mortality (AUC = 0.682; sensitivity = 60%, specificity = 63.79%) and 6-month mortality (AUC = 0.692; sensitivity = 60%, specificity = 66.03%). On the other hand, the HEART score had quite good prognostic value for in-hospital mortality (AUC = 0.726; sensitivity = 50%, specificity = 89.74%) and good prognostic value for 6-month mortality (AUC = 0.805; sensitivity = 57.1%, specificity = 97.14%). ConclusionThe GRACE scores demonstrate greater prognostic value for in-hospital mortality in patients with acute coronary syndrome compared to the TIMI and HEART scores.
