BACKGROUND: Although a lot of studies have shown serum uric acid (SUA) could be a marker of adverse prognosis in patients with acute myocardial infarction, the role of SUA as a risk factor for myocardial infarction is controversial. This study aimed to evaluate the association between hyperuricemia and short-term outcomes of elderly patients with acute ST-segment elevation myocardial infarction (STEMI).
METHODS: Six hundred and seventy-three elderly patients (≥ 60 years) were divided into high-SUA-level group (group H: N = 168) and low-SUA-level group (group L: N = 505) according to the SUA levels on admission. The following primary end points were evaluated within 30 days of AMI. The adverse events included postoperative angina pectoris, heart failure (Killip class ≥ II), and death. The comparisons were made between two groups in clinical and angiographic characteristics.
RESULTS: The incidences of postoperative angina pectoris, heart failure, and the total adverse cardiovascular events were significantly higher in group H than in group L. But the incidence of death was similar between groups. In group H, heart rate (HR), systolic and diastolic blood pressure, SUA, homocysteine (HCY), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and creatine kinase myocardial band (CKMB) peak were clearly higher compared with those in group L. The results of logistic regression showed that the incidence of 30-day adverse events was closely related to TG, HCY and SUA.
CONCLUSIONS: An elevated SUA level may be related to the short-term outcomes and seems to be an independent predictor of 30-day cardiovascular events in elderly patients with STEMI.
