Serum uric acid levels on admission and prognosis of acute coronary syndrome: a bi-institutional report

Abstract

Objective: This study aimed to determine the association between the baseline serum uric acid (SUA) level and the short-term outcomes of patients with acute coronary syndrome (ACS). Methods: In this retrospective, bi-institutional study, patients with a diagnosis of ACS were recruited and followed-up for 30 days regarding the development of major adverse cardiovascular and cerebrovascular events (MACCEs). The associations between the SUA level upon admission and cardiovascular morbidities and patient prognosis were examined using univariate and multivariate analyses. Results: A total of 145 patients with ACS, with a mean age of 67.5±12.2 years, were recruited in this study. The rates of cardiovascular risk factors were higher in patients with elevated SUA levels. A cumulative MACCE was reported in 42 (29%) patients (19.5% in normal individuals and 39.7% in patients with elevated SUA levels, respectively; P=0.007). Based on the receiver operating characteristic (ROC) curve analysis, an on-admission SUA level above 6.9 mg/dL could discriminate patients with MACCE from those without MACCE during 30 days of follow-up (AUC=0.637; 95% CI: 0.553–0.715), with 64.3% sensitivity and 66% specificity. Based on multivariate logistic regression analysis, an elevated SUA level was associated with an increased risk of MACCE (odds ratio, 15.353; 95% CI: 2.026–116.328). Conclusion: In patients with ACS, an elevated baseline SUA level was associated with a higher prevalence of cardiovascular risk factors and morbidities, as well as an increased risk of MACCE in a short-term follow-up.
