In a prospective study 192 new manifested type 2 (noninsulin dependent) diabetics were checked in view of prevalence of coronary heart disease (CHD) and hypertension in relation to concentration of lipids in serum. CHD was found in 49%, hypertension in 53% dominating females. Increased triglycerides (1.98 mmol/l) and decreased HDL-cholesterol i.s. (1.28 mmol/l) were characteristically, cholesterol (6.6 mmol/l) were within references, the lipoprotein-screening test was pathologically. Prevalence of CHD was associated with age, sex, hypertension, partly with triglycerides and weight and inverse with HDL-cholesterol i.s. but not with the concentration of blood glucose and insulin i.s. basal as well as stimulated (75 g oGTT). In conformity with other studies the differences in lipids alone would'nt be allowed to explain the high prevalence of CHD in new manifested type 2 diabetics.
