Coronary arteriographic findings in type-II and type-IV hyperlipoproteinaemia.

Coronary arteriography was performed in 46 patients with type-II and type-IV hyperlipoproteinaemia. Type-II patients had a high prevalence of main left coronary disease and of distal coronary atherosclerosis, while type-IV patients usually had disease localised to the proximal coronary tree. These differences may be related to the differing plasma-lipoprotein patterns in these two syndromes.
