A group of 514 males between the ages of 35 and 44, whose occupation involved strained mental work, were examined. Ischemic heart disease was diagnosed in 56 of them (10.7%); 191 formed a group with doubtful signs of ischemic heart disease, and 267 composed a group of practically healthy persons. Hypertensive disease was revealed in 18.4% and hyperlipoproteinemia in 20% of persons examined. There was a statistically significant difference between the group of healthy individuals and that of patients with ischemic heart disease in the frequency of hypertensive disease and hyperlipoproteinemia. Smoking, adiposity, low physical activity, and aggravated heredity were encountered at a practically equal rate in both groups. In half of the patients with ischemic heart disease hypertensive disease and hyperlipoproteinemia were not found, while other risk factors of ischemic heart disease were encountered no more frequently than in the group of healthy persons. Thus, just like most other epidemiologic studies, our investigation showed hypertensive disease and hyperlipoproteinemia to be of highest significance as ischemic heart disease risk factor.

It is reported of 726 patients incidentally elected and mainly with life-shortening risk factors. 341 (47.1p.c.) showed an increased concentration of neutral fats and/or total cholesterol in the serum. Type IV (49.8 p.c.) according to Fredrickson was observed most frequently, followed by type IIb (31.1 p.c.) and by type IIa (19.1 p.c.). Most of the patients with hyperlipoproteinemia were overweight (53.1 p.c.), 33.6 p.c. suffered from arterial hypertension, 25.3 p.c. from diseases of the liver, 10.9 p.c. from coronary heart diseases, and 8.7 p.c. from manifest diabetes mellitus. The distribution of different types of hyperlipoproteinemia among the various diseases deviates from that of the total number of patients observed in this study. Cases of hyperlipoproteinemia were observed most frequently in diseases of the kidney with arterial hypertension (62.7 p.c.), coronary heart diseases (60.8 p.c.), manifest gout (60.0 p.c.), manifest diabetes mellitus (58.7 p.c.), and hyperuricemia without symptoms (55.8 p.c.). Type-IV-hyperlipoproteinemia was observed most frequently within the different groups of patients with life-shortening risk factors. An exception was the group of patients suffering from malignancies. Type IIb was found most frequently within the group of patients suffering from malignancies.

Clinical and coronary arteriographic findings were evaluated in patients with angina pectoris who were considered not to have diabetes mellitus or to have chemical or clinical diabetes. Each of the three groups consisted of 100 consecutive referred patients. Neither the age of the patients nor duration of symptoms differed significantly among the groups. Hypertension, gout, and peripheral vascular disease were more frequent in the patients with clinical diabetes. There was no difference in serum cholesterol concentration among the groups, but plasma triglyceride levels and the frequency of type 4 hyperlipoproteinemia were significantly higher (p less than 0.01) in the chemical and clinical diabetic groups than in the nondiabetic patients. Coronary arteriographic observations indicated that the severity of the coronary arterial disease was greater in both diabetic groups than in nondiabetic patients. The difference in the coronary scores among the three groups of patients interacts to some extent with the triglyceride level, since a high score in the diabetic groups was noted only in the presence of an elevated tryglyceride concentration. The results indicate that the increased severity of coronary arterial disease in diabetic patients is not attributable to age, duration of symptoms, hypertension, type -4 hyperlipoproteinemia, or apparent severity of the glucose intolerance.

The families of 13 children who had presented hyperlipoproteinemia at birth were studied. Total cholesterol, LDL cholesterol, triglycerides and electrophoresis of LP were performed. The parameters studied were divided in three groups: a) Inespecific indicators (alpha-LP, betas/alphas relation). b) Indicators of the beta-LP group (total and LDL cholesterol and beta-LP). c) Indicators of the prebeta-LP group (TG, prebeta-LP and prebeta-1). In all cases at least one of the parents had hyperlipoproteinemia. All the parents, but one, showed alterations in the same group of indicators as their children. Obesity, diabetes mellitus, arterial hypertension, coronary insufficiency, myocardial infarction and cerebrovascular accident where observed in the families of the hiperlipidemic parents, but not on those of the normolipemic parents.

Cardiovascular diseases are the leading cause of death in Western countries, with an enormous increase in death rate and involvement of younger age groups during the last decades. This applies especially to coronary heart disease and is mainly caused by first-degree risk factors: hypertension, hyperlipoproteinemia, cigarette smoking, gout, obesity, polycythemia, lack of physical activity, and stress. These risk factors are discussed with special reference to overnutrition and increased cholesterol levels. Recent resuults of research concerning lipids and their relation to atherosclerosis are reviewed.

The aim of the present study was to determine whether skin fibroblasts derived from patients with ischemic heart disease (IHD), which could not be related to accepted risk factors, would show a metabolic abnormality with respect to lipid or lipoprotein metabolism. Male patients 30-52 years old suffering from IHD were subdivided into two groups: those in whom IHD was not associated with risk factors such as hypertension, hyperlipoproteinemia, diabetes or smoking (group I); and those in whom heavy smoking was the only major risk factor recognized (group II). The controls were patients with angiographically normal coronary arteries (group III). Skin fibroblasts obtained from these patients were cultured and investigated with respect to metabolism of low density lipoprotein (LDL), synthesis of cellular lipids and induction of cholesterol ester accumulation in the presence of chloroquine, an inhibitor of lysosomal hydrolases. After 24 h incubation, the uptake and degradation of LDL protein in cells from patients of group II was significantly higher than in the controls, group III, but not different from those of group I. Hydrolysis of [3H] cholesterol linoleate, and incorporation of [3H] oleic acid into total lipids and into cholesterol esters was similar in cell cultures of the 3 groups studied. After exposure to chloroquine and LDL, the cells from the different donors accumulated cholesterol ester to a similar extent. Thus, whereas no significant difference was encountered in the lipid and lipoprotein metabolism in cells of patients with IHD without risk factors and controls, some increase in LDL metabolism was seen in cells from patients with IHD and with a history of smoking. It remains to be determined whether this increase was causally related to smoking.

In an attempt to retrain family doctors in hypertension and hyperlipoproteinemia, computer assisted instruction (CAI) was assessed in fourteen doctors (Group 1) and its efficiency was compared to that of traditional lectures given to twenty-one doctors (Group 2). The same objectives, contents and illustrations were used in both teaching approaches. There was no significant difference for age, year of graduation and type of practice in the two groups. Comparison between pre-test and immediate post-test revealed a significant gain of knowledge for hyperlipoproteinemia (group 1, 33% and group 2, 22%) and hypertension (group 1, 16% and Group 2, 19%). A year later a similar post-test was done in both groups, and no significant difference was found between this late post-test and the pre-test. CAI applied to family doctors is as efficient for learning as traditional lectures, and both approaches failed to show retention of knowledge after one year. This is perhaps the result of having selected instructional objectives of theoretical more than practical value.

The high incidence of cardio- or cerebro-vascular diseases is positively correlated with hyperlipoproteinemia. A large-scale screening of blood donor's populations could be used for the prevention of the atherogenic disease. Therefore lipoproteins electrophoresis on cellogel was compared with serum levels of triglycerides, cholesterol and lipids in 1184 blood donors (792 men, 392 women). The electrophoretic pattern was found abnormal in 32 cases (25 men, 7 women). It was a type IIb hyperlipoproteinemia, according to the classification of the World Health Organization. In these 32 subjects, serum triglycerides, cholesterol and lipids concentrations were significantly higher (p less than 0,001) than in 41 other donors with a normal electrophoretic pattern. A good positive correlation was found between high blood pressure or obesity or blood group O and abnormal electrophoretic pattern. Lipoproteins electrophoresis on cellogel appears to be a suitable test (easy, fast and economical) in large-scale screening for dyslipidemia in subjects over 40, or at least in cases of mild hypertension or obesity.

Ischemic optic neuropathy and retinal arterial occlusion are 2 forms of arterial occlusive disease affecting the eye. Reports in the literature suggest platelet hyperactivity in acute arterial occlusive diseases affecting other organ systems. Therefore, 14 patients with ischemic optic neuropathy and 17 patients with central or branch retinal artery occlusion were studied to determine whether platelets have a role in the pathogenesis of these vascular occlusive disorders. The results of the following investigations were no different in these patients compared with those in 18 control patients with non-vascular eye diseases: prothrombin times, partial thromboplastin times, plasma fibrinogen, factor V, factor VIII, platelet counts and threshold concentrations of ADP, epinephrine and collagen resulting in secondary platelet aggregation and serotonin release. In contrast, platelet coagulant activities concerned with the early stages of intrinsic coagulation were significantly increased in patients with retinal artery occlusion without hypertension or type IV hyperlipoproteinemia, but generally normal in patients with ischemic optic neuropathy and in patients with retinal artery occlusion associated with hypertension, type IV hyperlipoproteinemia, diabetes mellitus and generalized atherosclerosis. These results are consistent with a platelet contribution to retinal arterial occlusive disease in patients without other known contributing factors such as hypertension, serum lipid abnormalities, diabetes mellitus and generalized atherosclerosis and may have implications regarding prophylaxis.

For substantiation of definite methodological approaches in the biochemical investigations an analysis of published data was carried out. Correlation was considered between one of the early alterations in vessel wall, preceding atherosclerosis, namely proliferation of smooth muscle cells and factors of risk of ishemic heart impairment -- hyperlipoproteinemia, hypertension, smoking. The analysis showed that each of these factors of risk as well as thrombosis increased the proliferation of smooth muscle cells and thereby promoted the development of atherosclerosis. Thus, biochemical research must be directed not only towards revealing of developed impairments in lipoprotein metabolism but the biochemical approach has to be used for diagnosis of the primary impairments in metabolic processes, preceding hyperlipoproteinemia, stable increase in arterial pressure, thrombosis. This approach enables to reveal the early alterations and to begin the rational primary prophylaxis of atherosclerosis.
