Abstract
Many studies of atherosclerosis have indicated hyperlipidaemia as a predisposing factor to vascular disease. The relationship holds even for mild degrees of hyperlipidaemia, a fact that underlines the importance of this category of disorders. Both primary and secondary hyperlipidaemias represent such a variety of abnormalities that an internationally acceptable provisional classification is highly desirable in order to facilitate communication between scientists with different backgrounds.
The present memorandum presents such a classification; it briefly describes the criteria for diagnosis of the main types of hyperlipidaemia as well as the methods of their determination. Because lipoproteins offer more information than analysis of plasma lipids (most of the plasma lipids being bound to various proteins), the classification is based on lipoprotein analyses by electrophoresis and ultracentrifugation. Simpler methods, however, such as the observation of plasma and measurements of cholesterol and triglycerides, are used to the fullest possible extent in determining the lipoprotein patterns.
