Associations of impaired glucose metabolism and dyslipidemia with cardiovascular diseases: what have we learned from Japanese cohort studies for individualized prevention and treatment?

Abstract

Metabolic disorder is a modifiable risk factor for cardiovascular diseases (CVD), and lifestyle modification is the key to improving metabolic disorder. Diabetes mellitus has been shown to be a risk factor for coronary heart disease (CHD) and ischemic stroke in both Western and Japanese populations. An association between impaired fasting glucose and pre-hypertension found in an urban Japanese population emphasized the combined risk of CVD. Mean total cholesterol levels in Japan have been increasing in the last three decades. The Japanese evidence for the positive association of total cholesterol with CHD is similar to that in the West. Higher low-density lipoprotein cholesterol (LDL-C) levels pose an increased risk of CHD and atherothrombotic infarction, whereas lower LDL-C levels may pose an increased risk of intracerebral hemorrhage in Japan. Overall, the studies reviewed here show that impaired glucose metabolism and dyslipidemia are emerging risk factors for CVD in the Japanese population.
