Significant reduction of angina threshold (145 Imp./min to 134 Imp./min) and increase of ST-segment depression (0.13 to 0.17 mV) indicating progression of coronary artery disease was seen in 34 subjects studied by atrial pacing at intervals betion (0.22 mV to 0.12 mV) during exercise, which correlated significantly with decrease of heart rate (121 to 110 beats/min), is interpreted as consequence of diminished sympathetic activity and myocardial O(2)-demand. The change of hemodynamic parameters during controlled exercise does not allow evaluation concerning the progress of coronary artery disease, whereas cardiac stress test with atrial pacing is reproducible. There was no difference in relation to reduction of angina threshold between the group after combined longterm medication with nitrate and ss-blocking agent and the control group. Plasma lipid abnormalities were predictive of subsequent reduction of angina threshold. Severe 2 and 3 vessel obstruction was seen more frequently in patients exhibiting reduction of angina threshold. Level of uric acid, obesity, hypertension, age, combination of risk factors, the initially studied myocardial lactate production and angina threshold during exercise and atrial pacing had no predictive value concerning reduction of angina threshold.

1. Excessive amounts of food (two-fold more than the ad libitum intake) introduced into the gastro-intestinal tract of three adult male fowls, for 5 weeks, caused a marked increase in body weight resulting mainly from fat deposition. 2. The induced obesity was accompanied by an increase of the rectal temperature (0-2 to 0-3 degrees C) and a decrease of the skin and comb temperatures, a cessation in the growth of the comb, a reduction in the blood packed cell volume, an eight-fold reduction in the number of spermatozoa in the vasa deferentia and a concomitant depression in their motility. 3. A decrease of the testosterone and an increase of luteinising hormone concentrations in the blood plasma was obtained in two of the three treated birds.

Most patients with extreme obesity do not exhibit alveolar hypoventilation, but an intriguing minority do. The mechanism(s) of this phenomenon remain unknown. A disorder in ventilatory control has been suggested as a major factor in the pathogenesis of the obesity-hypoventilation syndrome. Accordingly, hypoxic and hypercapnic ventilatory drives were measured in 10 patients with the typical symptoms of the syndrome: obesity, hypersomnolence, hypercapnia, hypoxemia, polycythemia and cor pulmonale. Hypoxic ventilatory drive, measured as the shape parameter A, averaged 21.9 +/- 5.35, approximately one-sixth that in normal controls, A = 126 +/- 8.6 (P less than 0.01). The ventilatory response to hypercapnia also was markedly reduced, the slope of the response averaging 0.51 +/- 0.005, or about one-third the normal value of 1.83 +/- 0.13 (P less than 0.01). This decreased responsiveness in hypoxic and hypercapnic ventilatory drive was consistent throughout the group. The depression in ventilatory drive found in the obesity-hypoventilation syndrome may be causally related to the alveolar hypoventilation manifested by these patients.

Concentrations of immunoreactive insulin activity (IRI) and proinsulin activity (IRP), blood glucose, free fatty acids (FFA), glycerol, cholesterol, triglycerides were analyzed in 140 subjects suspect of protodiabetes and 50 healthy persons before, during and after a glucose infusion test (GIT). The protodiabetic subjects were classified into normweight, overweight, obese, hyperlipemic groups with diet or with Regadrin therapy and each of them subdivided into such with normal and such with pathological carbohydrate tolerance. Norm- and overweight subjects with asymptomatic diabetes were characterized by a significant reduction of insulin secretion during both phases. Obese patients with or without hyperlipoproteinemia demonstrated an increased IRI reaction during the late phase of secretion. Carbohydrate intolerance was associated with an enhancement of basal triglyceride levels and a reduced depression of glycerol and FFA during the GIT. There were no differences in fasting or reactive IRP concentrations between healthy and protodiabetic subjects with normal carbohydrate tolerance. In asymptomatic diabetes the IRP levels were increased during the late secretion phase, but the percentage of IRP in total IRI was normal or--in existing high response--significantly reduced in comparison to norm response. The results do not support an enhanced IRP secretion as the cause of carbohydrate intolerance.

The relation between fatness and aspects of psychological status was investigated in a representative sample (339 men and 400 women) of a middle-aged suburban population. A significant positive relation was found between substantial obesity and low levels of anxiety (in men and women) and depression (in men).

A questionnaire was constructed to examine the relationship between eating habits and emotional attitudes toward food. This was administered to 60 individuals who varied widely in body weight relative to the statistically determined optimum for their age and sex. Correlations between item scores and weight discrepancy values from optimum revealed a number of significant correlations. The more the degree of overweight, the greater the tendency to have problems in three areas: depression, anxiety and impulsivity. In addition, the number of overweight relatives in one's immediate family also is related to an individual's degree of overweight. Some implications for the therapy of obesity were suggested.

The side effects of using estrogen treatments to relieve menopausal symptoms in women are presented. Estrogens are effective in relieving headaches, vertigo, palpitations, and nervous symptoms such as depression, as well as degeneration and atrophy of the genital organs. In Norway, 2.5% of women over 45 as compared with 50% in the U.S. use estrogens to relieve menopausal symptoms. The incidence of endometrial cancer has risen from 9.2/100,000 in 1955 to 15.4 in 1974. Increased susceptibility to endometrial cancer has been linked to long-term use of estrogens, obesity, hypertension, diabetes, and nulliparity. In American studies, Premarin has been associated with increased risk of cancer related to the chemical equilinine, which has a long half-life. After menopause, the need for estrogen is met by the conversion of androstenedione, which is produced by the adrenal gland. When estrogens are taken, it may result in an overstimulation of the endometrium, which could cause cancer. Estrogens have bene found useful and safe for short-term relief of menopausal symptoms, and any patient using estrogens should be under routine observation to prevent development of cancer.

The past decade has seen a shift in the strategy for hypertension treatment from stepped therapy--a highly structured monolithic series of steps--to recommendations for a more individualized selection of treatment. Severe hypertension is a clear indicator to bypass traditional steps. Demographic factors, such as age, gender, and race, are often cited, but have proved to be less helpful. Concomitant medical conditions and problems are very common and are more often the crucial determinants in the selection of antihypertensive therapy. Coronary artery disease, diabetes mellitus, heart failure, azotemia, asthma, and chronic obstructive pulmonary artery disease, anxiety, and depression are all common, and each has implications for the selection of antihypertensive therapy. Blood pressure reduction is a surrogate for reduction of cardiovascular risk, and therefore, consideration of concomitant medical problems has extended to left ventricular hypertrophy, obesity, mild hyperlipidemia, and insulin resistance, as additional risk factors in hypertension. Consideration of all these factors makes it possible to individualize antihypertensive therapy in most patients today.

Centrally acting appetite suppressant drugs used in the treatment of obesity fall into 2 broad pharmacological categories; those which act via brain catecholamine pathways and those which act via serotonin pathways. Of the former group, amphetamine and phenmetrazine are no longer recommended because of their stimulant properties and addictive potential. The remaining drugs in this class include amfepramone (diethylpropion), phentermine, mazindol and phenylpropanolamine. All have been shown to reduce appetite and lower food intake, thereby helping obese patients more easily keep to a low-calorie diet and lose weight. They all have some sympathomimetic and stimulant properties. Anorectic drugs which promote serotonin neurotransmission have no such stimulant or sympathomimetic properties. They are fenfluramine, together with its recently introduced dextrorotatory stereoisomer dexfenfluramine, and fluoxetine. They reduce appetite and food intake and are effective in the treatment of obesity. Anorectic drugs should be reserved for those who are clinically at risk from being overweight, and then only as part of a comprehensive weight-reducing programme including regular dietary counselling. Although current licensing regulations only allow their use over a relatively short period (12 to 16 weeks), clinical trials have shown them to be effective over longer periods, particularly in preventing weight regain. Of the compounds currently indicated for use in obesity, dexfenfluramine appears to have the most suitable pharmacological profile, although it should not be given to patients with a history of depression. When used appropriately, appetite suppressants can be of real therapeutic benefit, and pose little risk.

The goal of cardiac rehabilitation is to optimize function through attention to the patient's medical needs, risk factors for recurrent events, physical reconditioning, and psycho-social needs. Medical needs include beta-adrenergic blocking agents and aspirin unless contraindicated, angiotensin converting inhibitors for left ventricular dysfunction, and relief of residual ischemia. Smoking, lipid abnormalities, physical inactivity, and hypertension remain important predictors of reinfarction and death and must be controlled. Obesity must be addressed because it exacerbates these problems. Therefore, the principles of behavior change should be applied to help patients control their risk factors and adopt healthy lifestyles. Smoking cessation and appropriate dietary behaviors can be adopted by the patient while in the hospital. Physical reconditioning can also begin with twice-daily exercises. After discharge from hospital and after an initial submaximal exercise evaluation, the patient will benefit from three sessions per week of outpatient cardiac rehabilitation for six to eight weeks. These sessions should last about an hour and raise the patient's heart rate as much as 30 beats per minute. Along with physical reconditioning, the cardiac rehabilitation program provides an opportunity to address risk factor modification, return to work, return to sexual activity, management of depression and anxiety, and the presence of risk factors in the patient's family. The patient should attend reinforcing sessions every three months for the first year and as necessary after that to control risk factors and reinforce the necessity for physical fitness.
