Associations between coronary heart disease and individual components of the metabolic syndrome according to glucose tolerance status.
OBJECTIVE
To assess whether the contributions of individual metabolic syndrome components to coronary heart disease (CHD) risk vary in patients with different glucose tolerance.


METHODS
A total of 1619 patients were included in this cross-sectional study. CHD, metabolic syndrome and  glucose tolerance were assessed using coronary angiography, anthropometric and biochemical parameters, and an oral glucose tolerance test, respectively. Associations between CHD and components of metabolic syndrome were determined using logistic regression analysis.


RESULTS
Low high-density  lipoprotein-cholesterol (HDL-C) was the only CHD risk factor in patients with both CHD and metabolic syndrome who had normal glucose tolerance, after adjustments for age, smoking and low-density lipoprotein-cholesterol (LDL-C) concentration. In patients with CHD plus metabolic syndrome and  prediabetes, the most important risk factor was hypertension; additional risk factors were high postprandial blood glucose (PBG) and low HDL-C. In patients with CHD plus metabolic syndrome and diabetes, high PBG was the strongest risk factor, followed by hypertension, high FBG and high waist  circumference.


CONCLUSIONS
Individual components of metabolic syndrome contributed variously to CHD across different glucose tolerance statuses.
