The relation of premorbid cardiovascular risk attributes routinely measures at regular biennial examinations to cardiac necropsy findings using a special autopsy protocol was examined among 127 decedents of the Framingham cohort. Necropsy findings analyzed were: heart weight, left ventricular (LV) muscle thickness, percent luminal insufficiency of the coronary arteries, and percent intimal involvement with atherosclerosis. Clinical data analyzed included weight, height, blood pressure and serum cholesterol measured 1, 5, and 9 years prior to death. Systolic blood pressure, but not diastolic, correlated strongly with heart weight and LV muscle thickness in both sexes, and with atherosclerotic involvement in women, but not men. Serum cholesterol 1, 5, and 9 years antemortem all correlated positively with the degree of luminal insufficiency in men, while in women only cholesterol 9 years before death correlated significantly. In multivariate analysis only systolic pressure in women correlated independently with left ventricular muscle thickness and relative weight was the only independent correlate of heart weight. Only age was an independent significant correlate of the extent of coronary atherosclerosis in women. For men, coronary atherosclerotic involvement was independently correlated with only the serum cholesterol and measures of obesity were the major predictors of heart size. The degree of coronary pathology also correlated positively with heart weight in men and LV muscle thickness in women. In general clinical data measured just prior to death did not correlate as well with pathological findings as did earlier measurements.

Lecithin:cholesterol acyltransferase (LCAT) activity, lipid concentration, lipoprotein lipid concentrations and cholesteryl ester linoleic acid proportion were determined in the plasma of 85 subjects randomly selected from a population during a health screen survey. Mean fractional LCAT rate was significantly higher in men than in women. Molar LCAT rate correlated with low density lipoprotein (LDL) cholesterol concentration in men and with nearly all lipoprotein lipid concentrations in women. Most of these relationships were dependent on plasma unesterified cholesterol (UC) concentration. Fractional LCAT rate was correlated only with HDL cholesterol concentration in women and this relation was dependent on the influence of obesity. An inverse relationship between plasma cholesteryl ester (PCE) linoleic acid proportion and molar LCAT rate in women was also explained by influences of obesity on the data. Both fractional and molar LCAT rates were positively correlated with obesity (Quetelet's Index and subscapular skinfold thickness) in women but not in men. This study showed the influence of sex on nearly all correlations involving LCAT activity in combined groups of men and women.

Atherosclerosis is one of the most common causes of peripheral vascular disease. Complications result from arteries compromised because of focal accumulations of lipids and other materials within and between cells in the vessel walls. Factors including hyperlipidemia, hypertension, diabetes mellitus, obesity, physical inactivity, smoking, social stress, and genetic background have been implicated as promoting a higher risk of atherosclerosis and its consequences.

Excretion of catecholamines and DOPA was impaired in patients with metabolic-alimentary obesity, with ischemic disease of heart, with atherosclerosis and excessive weight. Distinct decrease in content of adrenaline, noradrenaline and DOPA was observed in patients with obesity; the phenomenon was less pronounced in ischemic disease of heart, mainly in aged patients. Correlation was found between the rate of excretion of catecholamines and DOPA and the extent of hyperlipidemia. Dietetics did not normalize completely the impairments studied. Additional administration of pyridoxine caused a favorable effect.

The weight of some organs [brain, heart, lungs, kidneys, liver] was ascertained in a group of 1,598 persons who died a violent death, and a comparison was made with values obtained in a group of persons who died of cardiac insufficiency. The figures found were correlated according to sex with age, obesity, lipomatosis, physical size, the presence and stage of atherosclerosis. --Within the violent death group, a correlation was also made between a subgroup with minimal or no presence of atherosclerosis and one with ascertained atherosclerosis. The average weight of the brain was found to be 1419.6 g in men, 1266 g in women; the heart--394.7 or 343 g; kidney--149.0 g or 124.1 g; lungs 1280.0 or 973.4 g; liver--1770.9 g or 1522.0 g.

Epidemiological aspects of obesity have been the object of few studies in Italy, and the results of these are reviewed and compared with those obtained in other developed countries. The prevalence of obesity has been investigated in pre-school and school-age children, in young conscripts and in workers at the Riuniti Hospital in Parma, and the results show that the problem of obesity in Italy is a serious one. More than 2000 obese subjects, attending the First Medical Clinic of Parma University, have been studied to establish how far overweight is responsible for pathological and disabling complications. Obesity was implicated as a major contributing factor in diabeties, atherosclerosis, hypertension, arthritis and many other disabling diseases. The social aspects of the problems of obesity are discussed, together with possible preventive and curative measures.

Risk factors were compared in 300 patients with brain stroke and 120 patients with neurosis or sciatic pains. It was found that arterial hypertension (p = 0.001) and diabetes (p = 0.01) were significantly more frequent in cases of brain stroke. Disturbances of lipid metabolism, tobacco smoking and obesity showed no significant difference. Extracerebral atherosclerosis (p = 0.001) increased the risk of stroke. Coronary arterial disease was most frequent (48.8%), myocardial infarction (8.3%) and calcifications in the aorta (32%) were second and third in frequency. Presence of at least two risk factors may be an indication to prophylactic treatment.

We studied the prevalence and the risk factor among the patients of gout in Mexico. Research was conducted in the National Institute of Cardiology and in our private practice. Prevalence of hiperuricemia and gout in the Institute of Cardiology was of 1% (970 out of nearly 100,000 patients). We divided those cases of two subgroups: Reumatology patients (333) and Cardiovascular patients (529). In the first group primary gout was (96.3), and (50.32% in the second. Risk factor was quite different too: nephropathy 9.9%, lithiasis 9.3%, pyelonephritis 2.7%, cardioangiosclerosis 12.9%, aortosclerosis 6.6%, coronary insufficiency 6.3%, myocardial infarction 0.9%, arterial hypertension 24.6% obesity 56.1% and diabetes 9.9% in the Reumatology group; in the Cardiovascular one, nephropathy 14.3%, lithiasis 12.2%, pyelonephritis 7.1%, cardioangiosclerosis 62.7%, aortosclerosis 31.7%, coronary insufficiency 24.9%, myocardial infarction 29%, arterial hypertension 51%, obesity 54.8% and diabetes 20.4%. Among the private practice patients prevalence was of 10.1% (961). In an early age (39 years) in men and a later one for women (53 years). Other characteristics of epidemiology and risk factor are: primary gout 89%, atherosclerosis 5%, coronary disease 4.6%, lithiasis 4.7%, nephropathy 2%, pyelonephritis 1%, obesity 43%, and diabetes 4.6%. In an small group of patients of our private practice we made an exhaustive study of risk factor and the metabolic disorder of lipids. We found the following frequency: 9.3 of nephropathy, 31.2% of lithiasis, 18.7% of pyelonephritis, 68.9% of cardioangiosclerosis, 46.8% de coronary insufficiency, 9.3% of myocardial infarction, 68.7% of arterial hypertension, 68.7% of obesity and 18.7% of diabetes. In the lipid profile we found an increase in triglicerids and prebeta lipoprotein. We have amply discussed the relation between hiperuricemia and pathology considered as a risk factor from the genetic point of view as well as the metabolic and circumstancial aspect. From all that we concluded that risk is multifactorial.

Clinical, angiological, and biochemical examinations were performed in 981 men and 30 women with organic afflictions of peripheral arteries, and in 411 men and 50 women without any signs of peripheral arterial lesions. Their family histories were thoroughly recorded with particular reference to the occurrence of myocardial infarction, cerebral accidents before and after the age of 60 years, and death of these causes; further, of hypertension, diabetes mellitus, obliterations and gangraenes, in each patient's siblings, parents, and all four grandparents. Furthermore, the significance of positive family history in combination with other risk factors was investigated. Family history can be considered positive with respect to obliterative atherosclerosis when in anyone of the patient's grandparents, parents, or siblings an obliteration of peripheral arteries is present or when anyone of them died of myocardial infarction or apoplexy, especially when aged under 60 years. Presence of several factors in the specified next of kin accelerates the obliterative process in the patient. A positive family history, however, plays no decisive role either alone or in combination with any other single risk factor, but only in combination with two or more other factors, one of which is always tobacco smoking; it is not significant in any combination with obesity.

Obesity leads to several complications that affect many body systems. This paper focuses mainly on the cardiovascular complications, which include coronary heart disease, cerebrovascular disease and stroke, and congestive heart failure; the last may be secondary not only to advanced coronary atherosclerosis, but also to other pathogenetic factors. The increased frequency of coronary heart disease in the obese is largely attributable to the commonly associated hypertension, diabetes mellitus and lipoprotein abnormalities, rather than the adiposity. The lipoprotein disorders that have a role in atherogenesis are decreased plasma concentrations of high-density lipoproteins and elevated plasma concentrations of low-density lipoproteins. Abnormalities in cholesterol metabolism are responsible for the increased frequency of cholelithiasis in obese persons. The factors that mediate the development of cardiovascular and gallbladder complications are correctable by an appropriate program of meal planning and physical activity.
