Hyperuricemia and long-term mortality in patients with acute myocardial infarction undergoing percutaneous coronary intervention
Abstract
Background: Although serum uric acid (UA) was regarded to be involved in cardiovascular disease, the role of serum UA (SUA) as a risk factor in acute myocardial infarction (AMI) is controversial. We investigated whether hyperuricemia was linked with long-term mortality in patients with AMI who underwent percutaneous coronary intervention (PCI).
Methods: Patients with AMI who received PCI were consecutively included. The definition of preprocedural hyperuricemia was a SUA level >7 mg/dL (417 mmol/L) in males and >6 mg/dL (357 mmol/L) in females. All-cause mortality was assessed during 2.3-year median follow up period.
Results: One thousand and five patients with AMI undergoing PCI were enrolled in a single center study, 307 (30.5%) patients had hyperuricemia. After adjusting for potential confounding factors, the multivariable analysis indicated that preprocedural hyperuricemia was related to an increased risk of all-cause mortality during the 2.3-year follow-up (HR: 1.97; 95% CI: 1.11–3.49; P=0.019).
Conclusions: Preprocedural hyperuricemia, independently from chronic kidney disease (CKD), is a significant and independent predictor of long-term mortality for patients with AMI who underwent PCI.
