LIPIDS AND LIPOPROTEINS AS RISK-FACTORS FOR CORONARY HEART-DISEASE INMEN WITH ABNORMAL GLUCOSE-TOLERANCE - THE HONOLULU-HEART-PROGRAM

Objectives. To evaluate lipids and lipoproteins as risk factors for co ronary heart disease (CHD) in older men with non-insulin-dependent dia betes (NIDDM) or abnormal glucose tolerance compared with normoglycaem ic men. Design. A prospective, population-based cohort study based on the lipoprotein examination (1970-72) of the Honolulu Heart Program. F ollow-up was through to December 1988. Setting. Honolulu, Hawaii. Subj ects. Japanese-American men, ages 51-72 at baseline: 2042 with lh gluc ose < 12.5 mmol l(-1) (normal group); 376 on oral hypoglycaemic agents or with lh glucose greater than or equal to 12.5 mmol l(-1) after 50 g oral glucose challenge (abnormal glucose tolerance group). None had prevalent coronary heart disease (CHD) or stroke at baseline. Main out come measures. Incident CHD: definite nonfatal myocardial infarction ( MI) or fatal CHD. Results. There were 221 incident cases in the normal group, and 65 in the abnormal glucose tolerance group. Total and high -density lipoprotein (HDL) cholesterol were significant predictors of incident CHD in men with NIDDM or abnormal glucose tolerance after con trolling for age, body-mass index, systolic blood pressure, pack-years of cigarettes and alcohol consumption (P < 0.05). Total, low-density lipoprotein (LDL) and very-low-density lipoprotein (VLDL) cholesterol were significant predictors in normal men, and HDL cholesterol was of borderline significance. Conclusions. Abnormal lipids and lipoproteins are significant, independent predictors of CHD in subjects with NIDDM or abnormal glucose tolerance. Attention to lipid and lipoproteins as CHD risk factors should be part of clinical management of these patie nts.
