Preparations of rabbit low density lipoproteins (LDL) labelled with 3H in the esterified and free cholesterol moieties and with 125I in the apoprotein moiety were injected intravenously into other rabbits. A substantial proportion of the esterified [3H]cholesterol removed from LDL during the first 30 min was recovered in the high density lipoprotein (HDL) fraction, while no such transfer of labelled apoprotein was observed. There was a clear cut differential in the decay of the different LDL components, slowest for the apoprotein, intermediate for esterified cholesterol and fastest for free cholesterol.

The present report concerns the biochemical and anatomo-pathological study of the skin and the plasma lipoprotein fractions in a young population (average age : 22 +/- 1.5 years). The levels of cutaneous cholesterol and the ratio HDL cholesterol/total cholesterol are closely linked even through the histological structure of the skin is still normal; the level of cutaneous cholesterol giving a good indication of the degree of vascular ageing. The observations confirm the usefulness of measuring these two parameters in the detection of early atherosclerosis.

Phthalazinol (EG 626), a thromboxane A2 antagonist and cyclic AMP phosphodiesterase inhibitor, has been shown to prevent the atherosclerosis induced in cholesterol fed rabbits. In an attempt to clarify the antiatherosclerotic mechanism, the effects of this compound on the lipolytic enzyme activities (cholesterol esterase and lipoprotein lipase) of rat aorta were examined in vivo. Administration of EG 626 (100-200 mg/kg, per os, daily, 1-2 weeks) affected neither the aortic lysosomal cholesterol esterase nor the acid phosphatase activity, whereas the lipoprotein lipase activity was signficantly decreased by the treatment. These results suggest that with an elevation in HDL-cholesterol, a decrease in lipoprotein lipase activity after ingestion of EG 626 might contribute, at least to some extent, to the prevention of arterial lipid accumulation.

Factors underlying spontaneous cardiac rupture were studied in a consecutive series of 30 hearts with ruptured infarcts removed at medicolegal autopsy. Normal and diseased heart muscle and narrowed coronary arteries were examined microscopically. The average age of the 15 women at death was 80 years, and of the 15 men, 73 years. All of the ruptures occurred through a recent transmural left ventricular myocardial infarction which was associated with coronary arteries severely narrowed by atherosclerosis. Nine (33 percent) of the cases showed an occlusive coronary thrombosis. Many of the subjects had no symptoms of recent myocardial ischaemia.

A high autopsy incidence, 7 of 50 cases (14%), of aortic dissection as the major cause of death in patients who died following aortocoronary saphenous vein bypass is reported. The patients ranged in age from 45 to 61 years, and all had moderately severe aortic atherosclerosis. None was hypertensive, and no significant predisposing aortic medial disease was recognized. Trauma during surgical cannulation with retrograde perfusion through atherosclerotic femoral or iliac arteries was considered the initiating event leading to ileo-aortic dissection in five of the seven patients. Damage secondary to aortic cross-clamping is suggested as the pathogenetic mechanism leading to dissection in the other two patients. In six patients, the dissection was Type I of DeBakey, and in one patient, Type II. Dissection was recognized intra-operatively in five of the seven patients. In older patients, particularly those likely to have atherosclerosis of the aorta and its main branches, vigilance regarding the possibility of aortic dissection developing during the course of cardiopulmonary bypass must be constant.

The condition of the distal bed of the cardiac coronary arteries was studied in 150 patients with ischemic heart disease. It proved to be affected with stenotic atherosclerosis in 20,6% of cases. The distal bed in patients with the chronic stage of ischemic heart disease hardly differed from that in patients with acute myocardial infarction. Total revascularization may be accomplished in 33% of cases with affection of three vessels of the cardiac coronary bed with stenotic atherosclerosis and in 96,5% of cases with affection of one vessel.

There were under observation 440 patients with ischemic heart disease due to atherosclerosis of the coronary arteries in the phase of exacerbation of the disease and 52 patients suffering from hypertensive disease with a clinical picture of ischemic heart disease; 192 practically healthy individuals were examined as controls. Significant increase in the levels of cholesterol, triglycerides, and glucose in blood of the patients with ischemic heart disease and of those with hypertensive disease was revealed. In patients with ischemic heart disease marked by pain and disorders of the rhythm as well as in individuals with hypertensive disease hormonal-metabolic shifts, monotypical in character, were noted. It is suggested that hormonal-regulatory disorders are of primary character in atherogenesis.

A brief resume of advances in atherosclerosis research over the past 30 years is presented, emphasizing the multidisciplinary origins of those advances. A somewhat more detailed review of progress in the lipoprotein field is presented as an example to illustrate the pace of research related to atherosclerosis. Finally, an attempt is made to identify some of the research areas that promise to yield valuable new insights in the next 30 years.

The history of vascular surgery and the developments that made it possible are briefly traced. Approaches to the treatment of arterial lesions are considered in terms of the characteristic anatomic, pathologic and clinical patterns of arteriosclerosis or atherosclerosis, the basic underlying lesion in most aneurysmal and occlusive diseases of the aorta and major arteries. The importance of appreciating the various patterns and rates of progression of atherosclerosis is emphasized.
