Abstrakt: To assess the prevalence of impaired homocysteine metabolism in young adults with arterial occlusive disease, 80 consecutive patients under 45 years old were screened. Various laboratory blood investigations and a standardized methionine loading test were performed. In the first 52 patients plasma levels of free homocysteine were determined; thereafter the levels of total homocysteine (a more sensitive measure of impaired homocysteine metabolism) were measured. The methionine loading test was abnormal in 15 patients (19 per cent) who did not differ from the other 65 with respect to prevalence of other risk factors, clinical characteristics, and electrocardiographic and angiographic findings. Blood levels of glucose, vitamins B6 and B12, folate, protein C and protein S, fibrinogen and low-density lipoprotein cholesterol did not differ significantly between the two groups. The prevalence of impaired homocysteine metabolism in young patients with arterial occlusive disease is greater than the 1-2 per cent found in the normal population.
