[The cardiovascular manifestations of mixed hyperlipidaemia. Revision of a series of 950 cases (author's transl)].

The cardiovascular consequences of mixed hyperlipideamia have been determined using a very large series of 950 cases. The early development and the prevalence of complications renders the disease severe, even in its minor forms of the grave forms of essential hypercholesterolaemia. Certain special features are worthy of mention:--the total loss of any parallelism between the biological severity and the development of vascular complications;--the probable role of slow pre-beta-lipoprotein in the determination of complications above all forms resistant to therapeutic reduction where its persistence is remarkable, which justifies the addition to known electrophoretic types III and II b a type, in the opinion of the authors just as common, with pre-beta-lipoprotein without any increase in L.D.L.
