(HealthDay) -- Elevated uric acid levels are predictive of one-year mortality in patients with acute coronary syndrome, according to a study published in the May 1 issue of The American Journal of Cardiology.

Gjin Ndrepepa, M.D., of the Deutsches Herzzentrum in Munich, Germany, and colleagues conducted a study involving 5,124 patients with who underwent percutaneous coronary intervention (PCI) to evaluate whether uric acid levels have any prognostic value in this patient population. Of the participants, 1,629 had acute ST-segment elevation (STEMI), 1,332 had acute non-STEMI, and 2,163 had . Participants were classified into four uric acid quartiles: quartile 1 (1.3 to <5.3 mg/dL), quartile 2 (5.3 to <6.3 mg/dL), quartile 3 (6.3 to <7.5 mg/dL), and quartile 4 (7.5 to 18.4 mg/dL). One-year mortality was the primary end point.

During follow-up, the researchers identified 450 deaths: 80 deaths in quartile 1, 77 in quartile 2, 72 in quartile 3, and 221 in quartile 4 (unadjusted hazard ratio, 3.05 for fourth versus first quartile uric acid). The association between uric acid and mortality persisted after adjustment, with every 1-mg/dL increase in the uric acid level correlating with a 12 percent increase in the adjusted risk for one-year mortality.

"Elevated levels of uric acid are an independent predictor of one-year mortality across the whole spectrum of patients with acute coronary syndromes treated with percutaneous coronary intervention," the authors write.
