Seven hundred and fifty asymptomatic European subjects aged 16 to 69 years from an urban general practice were screened for various coronary risk factors. Required information was completed for 98.9 percent of the total sample. The incidence of individual risk factors in males and females respectively were: smoking, 52.8 percent and 45.6 percent; obesity, 26.9 percent and 30.9 percent; definite hypertension, 5.6 percent and 4.0 percent; borderline hypertension, 5.3 percent and 5.1 percent; hyperlipidaemia, 12.8 percent and 8.0 percent; impaired glucose tolerance, 1.1 percent and 1.3 percent. Respective figures for males and females with regard to numbers of risk factors present were: one or more risks present, 68.5 percent and 66.9 percent; two or more, 26.5 percent and 23.5 percent; three or more, 8.0 percent and 4.5 percent; four risk factors present, 1.6 percent and 0.3 percent.

The influence of smoking, hyperlipidemia, and glucose intolerance on graft patency and rate of progression of obstructive disease in the native circulation was assessed in 99 patients 1 1/2 years after aortocoronary bypass grafting. There were 24 patients in whom none of these risk factors was identified. There were 42 patients with one, 29 with two, and four with three risk factors. Overall graft patency rate was 74%. Graft patency was not significantly influenced by any of these factors either singly or in combination. Progression of obstructive disease in both proximal and distal segments of grafted vessels and in nongrafted vessels was not significantly increased by the presence of one, two, or three risk factors. Over all, there was progression in 56% of segments proximal to grafts, in 8% distal to grafts, and in 14% of nongrafted vessels. Longer term studies will be required to establish any adverse influence of these risk factors on saphenous vein bypass grafts and native circulation.

Dietary Cr deficiency may cause the aging-related Cr depletion observed in humans. Such depletion, when it occurs with excessive consumption of sugar and other carbohydrates, may result in glucose intolerance, glycosuria, hyperinsulinemia, and hyperlipidemia. These metabolic disorders could explain why athero-sclerotic diseases are endemic to most Western industrial societies. This review detailed significant current research and findings on the manifestations of Cr deficiency in humans and animal models.

Fifty relatives of 7 families with high prevalence of obesity were investigated and the possibility was shown that there were three forms of familial obesity--normoinsulinemic obesity, hyperinsulinemic obesity and diabetic obesity. In normoinsulinemic obesity, both glucose tolerance and plasma lipids were normal with a few exceptions whereas in hyperinsulinemic obesity, mild glucose intolerance and manifest hyperlipidemia, and in diabetic obesity, blunted insulinogenic index and more advanced glucose intolerance with slight hyperlipidemia existed.

Fasting plasma concentrations of triglycerides (TG), cholesterol, immunoreactive insulin (IRI), and blood glucose were raised in 16 children with chronic renal failure on regular haemodialysis compared with 18 healthy children. In the patients plasma IRI correlated positively with plasma TG, while blood glucose did not correlate with IRI or lipid concentrations. Dietary intake, expressed as percentage of recommended intake for height-age, did not correlate with plasma lipids, but there was a positive correlation between plasma TG and the proportion of calories derived from carbohydrate. The children were not malnourished as evidenced by normal plasma albumin and transferrin concentrations. The mechanism of the hyperlipidaemia is unclear but it may be related to the glucose intolerance with hyperinsulinaemia which is found in uraemia. In view of the risk of premature atherosclerosis, plasma lipid concentrations should be monitored in children with chronic renal failure and attempts made to ameliorate hyperlipidaemia with appropriate dietary manipulations.

Thirty-one growth-hormone-deficient dwarfs were re-examined after a period of 10 to 12 years. These subjects had initially shown glucose intolerance, insulinopenia and hyperlipidemia comparable to those of diabetic patients matched for age and sex, but vascular complications were not present in dwarfs. After 10 years glucose tolerance became progessively more abnormal in dwarfs than could be accounted for by expected deterioration with age, and hyperglycemia after mixed meals remained greater than in control subjects. Serum lipid and serum lipoprotein concentrations were abnormal in over one third of the dwarfs. Despite the metabolic similarity to the diabetic patients, clinical complications of diabetes were absent in dwarfs: retinopathy did not occur, and the prevalence of hypertension and arteriosclerosis was considerably lower in dwarfs than in the diabetic subjects in both study periods. The follow-up data support the hypothesis that growth hormone has at least a supportive role in the pathogenesis of vascular disease in the diabetic state.

In an attempt to assess cardiac risk in non-cardiac surgery, 1001 patients over 40 years of age who underwent major operative procedures were examined preoperatively, observed through surgery, studied with at least one postoperative electrocardiogram, and followed until hospital discharge or death. Documented postoperative myocardial infarction occurred in only 18 patients; though most of these patients had some pre-existing heart disease, there were few preoperative factors which were statistically correlated with postoperative infarction. Postoperative pulmonary edema was strongly correlated with preoperative heart failure, but 21 of the 36 patients who developed pulmonary edema did not have any prior history of heart failure. Nearly all of these 21 patients were elderly, had abnormal preoperative electrocardiograms, and had intraabdominal or intrathoracic surgery. In the absence of an acute infarction, bifascicular conduction defects, with or without PR interval prolongation, never progressed to complete heart block. Spinal anesthesia protected against postoperative heart failure but not against other cardiac complication. By multivariate regression analysis, postoperative cardiac death was significantly correlated with (a) myocardial infarction in the previous 6 months; (b) third heart sound or jugular venous distention immediately preoperatively; (c) more than five premature ventricular contractions per minute documented at any time preoperatively; (d) rhythm other than sinus, or premature atrial contractions on preoperative electrocardiogram; (e) age over 70 years; (f) significant valvular aortic stenosis; (g) emergency operation; (h) a 33% or greater fall in systolic blood pressure for more than 10 minutes intraoperatively. Notably unimportant factors included smoking, glucose intolerance, hyperlipidemia, hypertension, peripheral atherosclerotic vascular disease, angina, and distant myocardial infarction.

Many alterations in metabolic and endocrine function occur in end-stage renal disease. Glucose intolerance is almost always present with uremia; it improves shortly after institution of regular hemodialysis. Hyperlipidemia (type IV) is prevalent, and atherosclerotic cardiovascular disease causes death in about 50% of patients receiving long-term hemodialysis. Although plasma levels of growth hormone usually are elevated, children with chronic renal failure show growth retardation. The occurrence of thyroid disorders is difficult to determine, since many clinical features of uremia are similar to those of hyperthyroidism and hypothyroidism. The incidence of duodenal ulcer is high, possibly due to high gastrin levels. Sex hormone disturbances are common. Anemia is a constant feature of chronic renal failure; patients usually tolerate it well.

The effect of medroxyprogesterone acetate (MPA) on basal circulating lipids, arginine-stimulated glucagon and insulin secretion, and glucose tolerance was studied in normal women. After 5 days of oral MPA treatment (10 mg/day), there was a small but significant decline in basal circulating triglycerides. No changes were observed in fasting plasma concentrations of cholesterol, free fatty acids, glucagon, insulin, or glucose; in the plasma glucagon, insulin, or glucose responses during L-arginine infusion; or in the plasma insulin or glucose responses during oral glucose tolerance tests. There was no correlation of any of these parameters with the observed decline in fasting plasma triglyceride concentrations. These results confirm previous reports of no consistent changes in lipid or glucose homeostasis in women using derivatives of 17alpha-acetoxyprogesterone derivatives for contraceptive purposes, and suggest that MPA may be a suitable alternative for those women who develop hyperlipemia or glucose intolerance when they use contraceptive agents which contain derivatives of ethinyl estradiol and nortestosterone.

A preliminary survey has been completed using manual densitometric technics to determine the mean retinal circulation times in groups of normal controls, offspring to two diabetic parents with normal glucose tolerance (prediabetics), and offspring of two diabetic parents with abnormal glucose tolerance (chemical diabetics). Comparisons of the mean retinal circulation time showed differences between the left eye and right eye in prediabetic and chemical diabetic groups and a sex difference in both normals and prediabetics. In addition, both age and per cent ideal body weight were inversely related to the mean retinal circulation time. The levels of fasting serum cholesterol, triglyceride, and growth hormone, in many instances, also appeared to be inversely related to the mean retinal circulation time. Similarly, the degree of glucose tolerance (determined by the area under the glucose curve above baseline) was significantly inversely related to the mean retinal circulation time. The mean retinal circulation time adjusted for per cent ideal weight was analyzed separately for both right eye and left eye, and a significantly shorter mean retinal circulation time was noted, particularly in males, for prediabetics than for normal controls and for chemical diabetics than for both prediabetics and normals. Analysis of the mean retinal circulation time adjusted for age showed similar differences. It is postulated that the genetic prediabetic state with or without glucose intolerance might be associated with significant alterations of mean retinal circulation time independent of age and per cent ideal weight. It is also suggested that a number of potentially meaningful interrelationships between the degree of glucose intolerance and/or hyperlipidemia might exist and should be further quantified.
