Background. Risk factors and especially the combination of multiple risk factors are associated with the development of atherosclerosis. Therefore, patients with an early manifestation of atherosclerotic disease are likely to show an extraordinary risk profile. We analysed the frequencies and severity of risk factors in young patients with manifest peripheral arterial occlusive disease as compared to old patients.
Methods. We analysed the risk profiles in 303 patients who were sent for interventional treatment of a symptomatic peripheral arterial occlusive disease. The risk profiles were described for different age groups (54 patients under 50 years of age, 194 patients from 51 to 74 years, 55 patients over 75 years). Multiple linear regression analysis and analysis of variance were performed to look for age-dependent effects.
Results. Elevated total cholesterol, and triglyceride levels and nicotine abuse were more frequent in patients younger than 50 years. Diabetes mellitus and hypertension were more frequent in patients older than 75 years. The different frequencies for smoking, diabetes mellitus and hypertension were age-related (p<0.05). Concerning laboratory parameters such as HDL- and LDL-cholesterol, fibrinogen, lipoprotein(a) and homocysteine there were no relevant age-related differences in frequency nor in absolute values with the exception of the hematocrit and uric acid. The coincidence with clinically manifest myocardial infarction was 11.15% in the patients under 50 years compared to 20.6% in those aged 51-74 years and 16.4% in those over 75 years, for cerebral stroke it was 5.6%, 17.5% and 14.5%, respectively. Patients under 50 years with peripheral arterial occlusive disease and a history of myocardial infarction were characterised by high levels of total cholesterol, triglyceride and lipoprotein(a). Excluding patients with prior myocardial infarction patients did not show any difference in risk profile between the three age groups.
Conclusions. In a population suffering from manifest peripheral arterial occlusive disease the risk profile in patients under 50 years is not different from that in older patients. In contrast an additional myocardial infarction in such a population is associated with pathological lipid profiles.
