Is serum uric acid a predictive factor for stroke in men with hypertriglyceridemia?

Abstract

This study investigated the association between serum uric acid (sUA) and stroke risk in men with hypertriglyceridemia. Between 2002 and 2012, male patients with pure hypertriglyceridemia and a triglyceride (TG) level ≥ 150 mg/dL were enrolled. Eligible patients were categorized into two groups according to their sUA levels (≥ and < 8 mg/dL). Clinical characteristics and comorbidities that are risk factors for stroke were recorded and compared between the groups. A total of 265 male patients (95 with sUA ≥ 8 mg/dL and 170 with sUA < 8 mg/dL) were enrolled. The incidence of ischemic type of stroke was significantly higher in patients with sUA ≥ 8 mg/dL (p = 0.038), particularly in the age range of 45-65 years. Multivariate Cox proportional analyses confirmed that age (p = 0.003) and UA (p = 0.019) were major predictive factors for stroke free (ischemic type of stroke) survival. Among men with hypertriglyceridemia, the incidence rate of ischemic type of stroke significantly increased with sUA levels ≥ 8 mg/dL, particularly in men aged 45 to 65 years. Hyperuricemia is considered a potential predictive factor for ischemic type of stroke and may indicate the need for preventive management in patients with hypertriglyceridemia (Tab. 3, Fig. 1, Ref. 28).
