Abstract

Elevated C-reactive protein (CRP) levels are associated with an increased risk of cardiovascular disease (CVD) in Caucasians; however, evidence is lacking for East Asians, who have low CRP levels. PubMed and Google Scholar searches were conducted (1966 through September 2014), and eight prospective studies in East Asian countries (China, Hong Kong, Japan, Korea, Macao, Mongolia, and Taiwan) that documented risk ratios of elevated CRP for CVD were included for meta-analysis with random-effects models. The overall association between CRP levels and stroke was significant in six studies (risk ratio = 1.40 [95% confidence interval {CI}, 1.10–1.77], P = 0.008). The association with ischemic stroke was more evident in subgroup analyses. For coronary heart disease (CHD) and CVD, the risk ratio was 1.75 (95% CI, 0.96–3.19, P = 0.07) and 1.76 (95% CI, 1.29–2.40, P, 0.001), respectively. Although East Asians have low CRP levels, this meta-analysis shows that elevated CRP levels were significantly associated with an increased risk of stroke, primarily ischemic stroke.
