1. There were significant correlation between hyperlipidemia and obesity, hypertension, abnormal ECG and abnormal eyeground. 2. The incidence of cerebral hemorrhage was closely associated with hypertension but not with hyperlipidemia. 3. It was proved that hypertension with both hyper-Ch and hyper-TG was highly related to the development of cerebral infarction. 4. It seemed that the incidence of myocardial infarction and angina pectoris was related to hypertension with hyper-Ch. 5. Therefore, the present study suggested that the control of hypercholesterolemia and hypertriglyceridemia was useful for the prevention of cerebro-cardiovascular disease.

In a population of 744 diabetics composed mainly of elderly female patients, 172 developed hypertension after the onset of diabetes. Compared to normotensive diabetics, they had an increased prevalence of diabetic retinopathy (p less than 0.001), cerebral accidents, ischemic disorders of the lower limbs and a decreased glomerular filtration rate (p less than 0.05); they are frequently insulin-dependent and difficult to manage. In 173 other indivuals the diabetes emerged several years after the hypertension. This group was characterized by relatively easily controlled blood sugar and increased prevalence of angina and myocardial infarction (p less than 0.001). The association of hypercholesteremia with hypertension increases the risk of coronary disease (p less than 0.02) and, to a lesser degree, of glomerular insufficiency. The prevalence of coronary symptoms increases with obesity (p less than 0.05) while retinopathy increases with insulin dependence (p less than 0.001). From this information it may be concluded that the importance of various risk factors in the diabetic chiefly varies according to the vascular territory involved: cerebral vascular accidents occur mainly in hypertensives, while the presence of retinopathies, proteinuria and peripheral ischemia is directly related to the diabetes and particularly to insulin dependence. The risk of coronary lesions increases considerably when hypertension is added to the diabetes, with an even greater risk in the case of a diabetic, hypertensive, hypercholesterolemic nexus.

The prevalence of coronary risk factors was assessed in 1,817 asymptomatic adults in Long Beach, California, at the beginning and end of a 10-11 month interval. The risk factors evaluated were hypercholesterolemia, hypertriglyceridemia, hypertension, smoking, hyperglycemia, and marked obesity. The results of the tests were sent to the participants and to their physicians. An educational program aimed at reducing coronary risk factors was offered to the first 1,250 persons screened. Eight hundred and seventy-two of those 1,250 allocated to the education group returned for a second screening. The prevalence of 0, 1, 2, 3, 4, 5, or 6 coronary risk factors did not change significantly between the two screens in either the total group of 1,817 adults or in the 872 adults in the educational program. The Long Beach Heart Association mass screening program for coronary risk factors was ineffective in reducing the number of coronary risk factors.

The known risk factors for atherosclerosis do not possess the same significance in young people as in the elderly. Hypercholesterolemia, diabetes and cigarette smoking appear to have a greater bearing below the age of 50 than later, particularly in myocardial infarction but also in apoplexy. On the other hand, hypertension is an important factor in the young and, especially in the case of apoplexy, even more so in advanced age. There is marked difference with regard to preexisting heart disease, which scarcely plays a role in myocardial infarction of the younger patient but is a factor in some 50% of hemiplegia cases. Only one fifth of elderly patients with this disease have no preexisting carcdiopathy. The similarity of the risk factors in elderly patients either with or without apoplexy is due to the fact that arteriosclerosis is already established in both groups and the risk factors which give rise to ischemia, thrombosis or embolism assume prominence. The therapeutic implications are briefly discussed.

Although unusual, coronary artery disease does occur in young women. It may be present to a severe degree between ages 20 and 30, but a typical history of angina pectoris by no means assures the presence of significant coronary artery disease. Proof that oral contraceptives predispose to coronary artery disease is lacking. It seems wise not to recommend them to young women with other known risk factors. Significant risk factors in a group of 1000 women under age 50 studied by cinecoronary arteriography for the evaluation of chest pain included cigarette smoking, hypertension, hypercholesteremia, and glucose intolerance. Combinations of factors increased the risk. Electrocardiographic abnormalities in themselves did not seem to increase the risk of coronary artery disease, but did seem to enhance it in combination with other factors. Electrocardiographic evidence of transmural myocardial infarction without significant coronary artery disease was more common in young women than in young men. Cinecoronary arteriography may possibly be performed after resolution of more severe lesions related to lysis of emboli or thrombi. Special conditions may temporarily increase myocardial oxygen requirements. Angia-like chest pain has been described in patients without significant coronary artery disease. Many have normal electrocardiograms and no known risk factors. Spasm has been mentioned among many possible causes, but is very difficult to tell whether or not underlying atherosclerotic lesions may be present. Whatever the cause, the prognosis for patients with angina-like chest pain and normal coronary arteriography seems excellent; early death is a rarity and improvement is common.

Autopsy findings of a 36-year-old male with familiar hypercholesterolemia were reported and discussed. Hyperlipoproteinemia found in this case might belong to the type IIa in the classification of hyperlipoproteinemia while there was no skin lesion such as xanthoma and hypertension. Remarkable strictures due to atherosclerotic plaques in the lumens of the right and left coronary arteries and wide-spread myocardial infarction in the left ventricle were found. In the aorta just above the aortic valve there were atherosclerotic plaques in which foam cells could be seen. From the histological findings of the aortic valve the possibility that the thickening of the valve might have been induced by a similar mechanism as that of aorta and coronary arteries was suggested.

A new strain of rat characterized by genetic obesity, endogenous hyperlipidemia, and hypertension was obtained in this laboratory. The abnormal phenotype is inherited as a homozygous recessive trait. The animals exhibit marked hypertriglyceridemia, moderate hypercholesterolemia, and an electrophoretic pattern resembling that of human Type IV hyperlipoproteinemia. The average life-span is less than 1 year, due largely to the development of premature renal and vascular disease. The kidney lesion has both glomerulonephritic and nephrosclerotic components and is accompanied by marked proteinuria. About 12% of animals develop urinary tract calculi. The vascular disease consists of fibrous and fatty-fibrous intimal plaques, and polyarteritis. The obese animal offers a useful model for investigating abnormal lipid metabolism and the etiology and pathogenesis of atherosclerosis.

The effect of renal hypertension on dry defatted tissue mass and lipid accumulation in different segments of the aortic intima was studied in both normally-fed and cholesterol-fed rabbits. In normally-fed rabbits hypertension caused an increase in intimal dry weight in the aorta. The increase was greatest in the lower thoracic intimal segment but was not significant in the aortic arch. The increase in tissue mass was not influenced by the addition of cholesterol to the diet and no regression of the increased tissue mass occurred when a 4-week period of hypertension was followed by a 4-week period of normotension. Hypertension did not increase the intimal cholesterol or phospholipid concentrations in normally-fed rabbits, suggesting that an observed increase in lipid content represented the cellular component of the intimal hypertrophy. Hypertension in cholesterol-fed animals caused preferential lipid accumulation in the lower thoracic segment, an effect that was independent of the total intimal cholesterol level. Intimal cholesterol, cholesterol ester and phospholipid were all increased. When a 4-week period of normotension and cholesterol feeding was preceded by a 4-week period of hypertension with normal feeding the amount of cholesterol deposited did not exceed that of the normotensive control, suggesting either that hypertension increased intimal permeability to lipid only in the presence of hypercholesterolaemia, or that healing of damaged intima had occurred before hypercholesterolaemia was fully established.

The screening phase of a multifactorial intervention study which is carried out under the direction of the WHO and the aim of which is the influence on mild forms of hypertension, hypercholesterolaemia and slightly disturbed glucose tolerance was supplemented by an electrocardiogram after work under the conditions of screening. The questionnaire contained in the investigation program for the statistical establishment of a typical angina pectoris after work according to Rose and the modified electrocardiographic test after work were tested concerning their evidence in the early recognition of a coronary sclerosis. As reference test served the Watt-step-test recommended by a group of experts of the WHO. An extensive correlation between screening after work and Watt-step-test was found. Questionnaire according to Rose and gradual load, however, had a smaller correspondence. The result of other investigations was that the distribution of the factors of risk does not give any clear reference to the existence of a latent coronary insufficiency.

A new strain of genetically obese rat recently obtained in our laboratory exhibits endogenous hyperlipidemia (marked hypertriglyceridemia and moderate hypercholesterolemia) and spontaneous hypertension. The animals die prematurely from kidney failure or from the complications of atherosclerosis. A low calorie diet proved to be highly beneficial to these rats. Body weight declined, obesity diminished, the hypertriglyceridemia was almost eliminated, and the hypercholesterolemia was reduced. However, the hypertensive state was not alleviated. Since the life span of the rats was greatly prolonged by a low calorie diet, the latter undoubtedly served to prevent or arrest the development of renal and vascular disease in these obese animals.
