Abstract: Background: Acute coronary syndrome (ACS) is a combination of clinical symptoms that indicate acute myocardial ischemia, consisting of unstable angina pectoris (unstable angina pectoris = UAP), ST-Segment Elevation Myocardial Infarction (STEMI), and Non-ST-Segment Elevation Myocardial Infarction (NSTEMI). Various factors are considered to be related to the incidence of ACS, one of the predisposing factors which is still being debated about its effect on ACS, namely uric acid levels. A previous study showed that adding serum uric acid values to the GRACE score may be better at identifying patients in the low-risk group.
