The Association Between No-Reflow and Serum Uric Acid/Albumin Ratio in Patients With Acute Myocardial Infarction Without ST Elevation

Abstract

This study evaluated the association between no-reflow (NR) and serum uric acid/albumin ratio (UAR) in 360 consecutive patients with non-ST-elevation myocardial infarction (NSTEMI) undergoing primary percutaneous coronary intervention. The study population was divided into two groups as follows: reflow (n = 310) and NR (n = 50) group. The thrombolysis in myocardial infarction (TIMI) flow score was used to describe NR. High UAR (Odds Ratio: 3.495, 95% CI; 1.216–10.048; P < .001) was found to be an independent predictor of NR. Additionally, UAR was positively correlated with the SYNTAX score and neutrophil/lymphocyte ratio; UAR was negatively correlated with left ventricular ejection fraction. The highest cut-off ratio of UAR predicting NR was found to be 1.35 with 68% sensitivity and 66.8% specificity. The area under the curve (AUC) for UAR was .768 (95% CI: .690-.847) after receiver operating characteristic (ROC) curve assessment. The AUC for UAR was found to be higher than for its components: serum uric acid (AUC: .655) and albumin (AUC: .663) ( P < .001 for each evaluation).
