title: Triglyceride levels and the risk of coronary artery disease: a view from Australia.
abstract: A prospective study of cardiovascular disease in elderly Australians commenced in 1988 in Dubbo, New South Wales. The study population comprised 1,237 men and 1,568 women aged > or = 60 years. The prevalence rates of coronary artery disease (CAD) and putative risk factors were examined cross-sectionally in the baseline data. The age-standardized rate of CAD was 23.8/100 men and 18.1/100 women. In a univariate analysis, the major risk factors for CAD were hypertension, diabetes, family history, reduced high-density lipoprotein (HDL) cholesterol levels, and increased triglyceride levels. The prevalence rate of CAD was examined in those with low-density lipoprotein (LDL):HDL ratios < 5.0 or > 5.0. Most notably in women, the CAD rate was 16/100 with an LDL.HDL ratio < or = 5.0 and 28/100 with an LDL.HDL ratio > 5.0. In the latter group, the rate was 21/100 in those with triglycerides < or = 2.3 mmol/liter and 36/100 in those with triglycerides > 2.3 mmol/liter. In a multiple logistic model that controlled for many potential risk factors or confounding variables, CAD in men was significantly predicted by age, hypertension (odds ratio = 1.40), family history (odds ratio = 2.05), and low HDL cholesterol (odds ratio = 0.78). Significant predictors in women were age, years of education (odds ratio = 0.82), hypertension (odds ratio = 1.45), family history (odds ratio = 1.77), serum triglycerides (odds ratio = 1.30), and low HDL cholesterol (odds ratio = 0.73). An independent gradient of CAD risk with increasing triglyceride levels and a similar gradient with decreasing HDL cholesterol levels were found in women.(ABSTRACT TRUNCATED AT 250 WORDS)
