Abstract: Background and purpose: It has not been fully determined whether non-high-density lipoprotein cholesterol (non-HDLC) levels are involved in vascular events, especially stroke, in general Asian populations. We evaluated the association between non-HDLC levels and the risk of type-specific cardiovascular disease in a prospective cohort study in Japan. Methods: A total of 2452 community-dwelling Japanese subjects aged ≥40 years were followed prospectively for 24 years. Results: The age- and sex-adjusted incidence of coronary heart diseases (CHD) significantly increased with elevating non-HDLC levels (P for trend < 0.001), but no such association was observed for ischemic and hemorrhagic strokes. With regard to ischemic stroke subtypes, the age- and sex-adjusted incidence of lacunar infarction significantly increased with elevating non-HDLC levels (P for trend < 0.01), and such tendency was seen for atherothrombotic infarction (P for trend = 0.098), while a significant inverse association was observed for cardioembolic infarction (P for trend = 0.007). After adjustment for confounders, namely, age, sex, diabetes, body mass index, systolic blood pressure, electrocardiogram abnormalities, current drinking, current smoking, and regular exercise, the associations remained significant for CHD [adjusted hazard ratio (HR) for a 1 standard deviation of non-HDLC concentrations = 1.17, 95% confidence interval (CI) = 1.02 to 1.35], atherothrombotic infarction (adjusted HR = 1.39, 95% CI = 1.09 to 1.79), and cardioembolic infarction (adjusted HR = 0.64, 95% CI = 0.47 to 0.85). Conclusions: Our findings suggest that elevated non-HDLC levels are a significant risk factor for the development of atherothrombotic infarction as well as CHD but reduce the risk of cardioembolic infarction in the general Japanese population.
