Prognostic value of serum uric acid levels in patients with non-STEMI undergoing percutaneous coronary intervention

Background Because myocardial infarction in young adults is rare, there has been limited research on the condition in this patient group. Very few data are available regarding the long-term outcomes of patients under 40 years of age with non-ST-segment elevation myocardial infarction (NSTEMI) undergoing invasive treatments. The prognostic value of uric acid (UA) in young patients with NSTEMI who undergo percutaneous coronary intervention (PCI) has also not been studied. The purpose of this study was to evaluate the long-term clinical outcomes of this specific subset of young patients. In addition, we aimed to identify the role of serum UA in predicting the long-term prognosis of young patients with NSTEMI who have undergone PCI. Methods We performed a retrospective analysis of 213 young adult patients (≤40 years old) with NSTEMI who underwent PCI during their hospitalization at our tertiary referral center. Results The mean age of the 213 patients was 36.8 ± 3.3 years (range, 21–40 years). The median follow-up was 930 days. Our patients were predominantly male (88.3%) and the most frequent traditional cardiovascular risk factors were smoking and dyslipidemia. Baseline TIMI flow 0–1, estimated glomerular filtration rate (eGFR), and UA were found to be independently correlated with long-term major adverse cardiovascular events (MACEs) in multivariate Cox regression analysis. Conclusion In the present study, baseline TIMI flow 0–1, admission eGFR, and UA levels were correlated with MACEs during long-term follow-up in young patients with NSTEMI.
