摘要:	Abstract Little is known about uric acid role for cardiovascular events in the Asian-Pacific countries with relatively low coronary heart disease (CHD) but high stroke events. Also, there is scanty evidence for repeated measures of uric acid levels among population. We examined associations of basic and repeated measures of uric acid level with CHD and stroke events in one Taiwanese adult community prospectively. Cox proportional hazards models, treating uric acid as baseline and time-dependent covariates, were used to assess the 11-year risk of CHD and stroke events. Among 3602 adult subjects older than 35 years, 86 incident CHD and 155 incident stroke cases were identified. The rate ratios of hyperuricemia ranged between 2.00 and 3.96, with higher risk ratios in women than in men. The rate differences and population attributable fractions were also higher in women than in men, implying that women had high risk of uric acid on cardiovascular events. After adjustment for age effect, time-dependent uric acid was associated with significant CHD risk in both genders (hazard risk [HR] 1.43, 95% CI: 1.10–1.87 in men and HR 1.22, 95% CI: 1.03–1.44 in women). But the magnitude of hazard risks decreased after adjusting more atherosclerotic risk factors for CHD. For stroke event, the age-adjusted hazard risk of time-dependent continuous uric acid level was 1.23 (95% CI: 1.00–1.54) in men and 1.36 (95% CI: 1.05–1.75) in women. Multiple adjustment by risk factors demonstrated that uric acid was still a significant predictor for stroke in women (HR 1.32, 95% CI: 1.00–1.73). The similar hazard risk patterns existed for binary categories of hyperuricemia. Subgroup analyses demonstrated uric acid had significant risk only in hypertension and metabolic syndrome subgroups, not in their counterparts. We concluded that uric acid, in the baseline and time-dependent variables, could predict cardiovascular events in the community of relatively low CHD but high stroke risk in Taiwan.
