Background: Serum uric acid (SUA) has been correlated with cardiac morbidity\nand mortality. However, its prognostic value in acute ST-segment\nelevation myocardial infarction (STEMI) is still uncertain. The aim of this\nstudy was to evaluate the prognostic value of SUA on admission in patients\nwith STEMI undergoing primary percutaneous coronary intervention (PPCI).\nMethods: We prospectively enrolled 150 STEMI patients underwent PPCI.\nThe mean age of the studied population was 56.1 years, 78% were males while\n22% were females. Patients were divided into tertiles based on the basal serum\nuric acid level. Patients with high SUA (n = 72) was defined as a value in\nthe third tertile (>6.4 mg/dl), and a low SUA group (n = 78) was set as a value\nin the lower two tertiles (<6.4 mg/dl). Clinical characteristics, angiographic\nfindings, echocardiographic data, in-hospital and three-month outcomes of\nPPCI were analyzed. Results: SUA level on admission carried prognostic value\nin patients with STEMI undergoing PPCI where the low uric acid group\nhad better KILLIP class (P = 0.001), better TIMI flow (P = 0.001), higher ejection\nfraction����
