Abstract
The serum beta/alpha lipid ratios were estimated by electrophoresis in 4 groups of people. These comprised 44 male patients with intermittent claudication; 61 men who were matched for age with the previous group and who were clinically free of cardiovascular disease; 30 male patients who had recently had a myocardial infarction; and a further group of 30 male controls whose physical activity was limited by factors other than disease. The highest mean serum beta/alpha lipid ratio was found among the patients with intermittent claudication and was very significantly higher than the ratios found among the other 3 groups. The difference in the ratios between the patients with myocardial infarction and the 2 control groups was not significant. These differences and in particular the difference in the ratios between the patients with myocardial infarction and intermittent claudication are discussed.
