559 CHOLESTEROL AND TRIGLYCERIDE STUDIES IN VASCULAR DISEASE: ALL PATIENTS AGED

50-59

Statistical significance as compared with controls (Student’s t test).

between normal and low H.D.L.-cholesterol in the range 20-25%. The findings of Bradby et al. differ from our experience. We measured enzymatically triglyceride and total and H.D.L.-cholesterol (heparin/manganous chloride method) in 96 patients with P.V.D., 80 patients with C.H.D., and 72 controls. P.V.D. was confirmed by angiography and C.H.D. by coronary angiography and/or exercise tests. Controls were free of signs of coronary, cerebral or peripheral vascular disease. The data are shown for the largest age-group in the table. For all the other age-groups (not shown) there were significantly higher total cholesterol levels in the C.H.D. group than in controls and, save for those aged 40-49, in the P.V.D. group also (r
