Background
Elderly patients with acute coronary syndromes (ACS) are a high-risk group with clinical and anatomical complexities that result in a poor prognosis. The Global Registry of Acute Coronary Event (GRACE) risk score was developed in a large multinational registry to predict in-hospital and 6-month mortality across the broad spectrum of ACS.
Methods
(i) To assess the in-hospital and 6-month clinical outcomes of conservative (CONS) vs. invasive (INV) strategy in elderly patients with ACS. (ii) The diagnostic performance of GRACE risk score to predict mortality is evaluated using receiver operating characteristic (ROC) curve analysis. The study was conducted on 158 elderly patients stratified into prespecified subgroups according to type of ACS, and whether the patient underwent revascularization during index hospitalization: Group A consisted of 118 patients presenting with STEMI (81 patients CONS and 37 patients INV); Group B included 40 patients presenting with high-risk unstable angina or NSTEMI (25 patients CONS and 15 patients INV).
