High Triglycerides and Low HDL Cholesterol and Blood Pressure and Risk of Ischemic Heart Disease

Treatment of high blood pressure (BP) has not produced the expected reduction in risk of ischemic heart disease (IHD). Subjects with high BP often have the metabolic syndrome X, an aggregation of abnormalities in glucose and lipid metabolism. We tested the hypothesis that the BP level would be less predictive of risk of IHD in those with high triglycerides (TG) and low HDL cholesterol (HDL-C), the characteristic dyslipidemia in the metabolic syndrome than in those without. Baseline measurements of fasting lipids, systolic BP (SBP), diastolic BP (DBP), and other risk factors were obtained in 2906 men, age 53 to 74 years, free of overt cardiovascular disease. High TG/low HDL-C was defined as TG >1.59 mmol/L and HDL-C
