Groups of patients such as the elderly, the diabetic and women have been studied to evaluate the effectiveness of coronary revascularization. In this report 77 patients under age 40 years undergoing coronary revascularization were studied. There was a high prevalence rate of predisposing factors. Sixty-eight percent reported a family history of heart disease and 27 percent a history of diabetes; 57 percent were hypertensive, 43 percent were overweight, 91 percent smoked, 5 percent were diabetic and 16 percent had abnormal glucose tolerance curves. Sixty-four percent had hypercholesterolemia (cholesterol 250 mg/100 ml) and 56 percent hyperlipidemia. Forty-four percent had had a previous myocardial infarction; 95 percent had angina pectoris, 12 percent preinfarction angina and 9 percent congestive cardiac failure. There were no operative deaths. The incidence rate of perioperative myocardial infarction (new Q waves in the electrocardiogram) was 4 percent. The mean length of of follow-up was 26 months (range 6 months to 5 years). The late mortality rate was 4 percent. Eight percent had a late myocardial infarction. Overall graft patency was 85 percent. Sixty-seven percent of patients were free of angina, and 17 percent were in improved condition. Seventy-one percent returned to work, while 29 percent remained unemployed. This study shows that in young patients, coronary revascularization is associated with low mortality and morbidity rates and that, despite the wide prevalence of predisposing factors, the prognosis and graft patency rate of these patients are similar to those of other groups.

A study of the clinical profile of gout-diagnosed patients was undertaken within general practice in Great Britain. At the time of the first attack of acute gouty arthritis, the mean age was 52.3 years and 15.6% of the total 1077 patients were female. Males had an earlier clinical onset than females and the average frequency of attacks of acute gouty arthritis was 0.91 per patient year. Ten per cent of the cases were believed to be secondary gout, with diuretic therapy the most frequent cause. The sample showed a highly significant association between gout and the higher social classes, a family history among blood relatives in 23% of cases, tophi were noted in 4.6% of cases where sought and 38.2% of cases were 10% or more overweight and significantly heavier than a non-gouty population. The great toe joint was most frequently involved, both in the first episode and in all acute episodes combined. The most frequently occurring associated chronic condition was hypertension which was present in 27.8% of cases. Renal stones occurred in 6.1% and renal impairment in 2.2%. Only 20.4% of the patients were referred to hospital, with the younger being referred more frequently than the older. Those with joint involvement other than the great toe had a greater chance of being referred, as did those who also had angina pectoris, myocardial infarction and hypertension. Allopurinol appeared to be the drug of choice for long-term control therapy and phenylbutazone for the acute attack.

We examined the prevalence of different categories of body weight in a random sample of men and women aged 35 to 64 years studied in 1985 in County Kilkenny, Ireland. The largest group was those classified as overweight-51.1% of men and 44.7% of women. There were 13.7% of men and 19.2% of women in the obese category. The obese were older but the distribution by social class did not differ significantly from the non-obese. Obese women had significantly more children born alive and a higher prevalence of positive angina questionnaire than those who were not obese. Serum total cholesterol was higher in obese men and HDL cholesterol was lower in obese men and obese women. Systolic and diastolic blood pressures were significantly higher in obese men and women but smoking status was similar. In a multiple logistic regression analysis, systolic blood pressure in men and diastolic in women remained significantly associated with obesity; there was an inverse association between obesity and HDL cholesterol in women and between obesity and HDL-cholesterol as a proportion of total cholesterol in men. A cardiovascular disease prevention programme should seek to prevent the increase in the prevalence of obesity with age which occurs in this population. It would also be important to assess other risk factors for coronary heart disease among those who are obese, with a view to reducing their overall level of risk.

Overweight and obesity may develop in individuals with genetically determined low resting energy expenditure. Drugs are among the recognised precipitating factors. The obesity promoting impact of beta-blockers is, however, less well known. Resting energy expenditure, and thermogenesis induced by stimuli such as meals, cold and heat exposure, stress and anxiety, have a facultative component mediated by the sympathoadrenal system through catecholamines working on beta-adrenoceptors. Treatment with beta-blockers reduces the facultative thermogenesis by 50-100 kcal/d, which corresponds to the weight gain of 2-5 kg/year reported in clinical trials. Treatment with beta-blockers also results in insulin resistance, which may aggravate existing diabetes and elicit diabetes in predisposed patients. Overweight and obesity are frequently complicated with hypertension and angina pectoris, which are often treated with beta-blockers. Obesity is associated with a defective sympathetic activity, and treatment with beta-blockers may further reduce facultative thermogenesis and promote weight gain. The consequence may be aggravation of hypertension, insulin resistance and other atherogenic factors. The causal therapy of android overweight and obesity complicated with diabetes or hypertension is a sufficient weight loss. If pharmacological treatment is inevitable, combined treatment with diuretics and ACE-inhibitors are most appropriate.

The prevalence of reported chronic diseases was studied in quintiles of waist/hip ratio and Quetelet index in 11,825 women aged 40-73 presenting for mammographic screening in the DOM-project. After adjustment for age and Quetelet index, increased waist/hip ratio was found to be associated with an increased prevalence of diabetes mellitus, hypertension, cholecystectomy and a lower prevalence of varicose veins. No associations were observed between waist/hip ratio and the prevalence of angina pectoris, gout and rheumatism. The odds ratios, adjusted for age and Quetelet index, of the highest versus the lowest quintile of waist/hip ratio were 3.4 (95% CI 1.4-8.3) for diabetes mellitus; 2.2 (95% CI 1.7-2.8) for hypertension; 2.0 (95% CI 1.2-3.4) for cholecystectomy, and 0.81 (95% CI 0.68-0.95) for varicose veins. After adjustment for waist/hip ratio and age, Quetelet index was found to be associated with an increased prevalence of hypertension, cholecystectomy and varicose veins. Quetelet index, however, was not found to be related to diabetes, gout or rheumatism. We conclude that in a representative sample of Dutch women older than 40 years, fat distribution in addition to overweight is related to important chronic diseases.

We examined the incidence of nonfatal and fatal coronary heart disease in relation to obesity in a prospective cohort study of 115,886 U.S. women who were 30 to 55 years of age in 1976 and free of diagnosed coronary disease, stroke, and cancer. During eight years of follow-up (775,430 person-years), we identified 605 first coronary events, including 306 nonfatal myocardial infarctions, 83 deaths due to coronary heart disease, and 216 cases of confirmed angina pectoris. A higher Quetelet index (weight in kilograms divided by the square of the height in meters) was positively associated with the occurrence of each category of coronary heart disease. For increasing levels of current Quetelet index (less than 21, 21 to less than 23, 23 to less than 25, 25 to less than 29, and greater than or equal to 29), the relative risks of nonfatal myocardial infarction and fatal coronary heart disease combined, as adjusted for age and cigarette smoking, were 1.0, 1.3, 1.3, 1.8, and 3.3 (Mantel-extension chi for trend = 7.29; P less than 0.00001). As expected, control for a history of hypertension, diabetes mellitus, and hypercholesterolemia--conditions known to be biologic effects of obesity--attenuated the strength of the association. The current Quetelet index was a more important determinant of coronary risk than that at the age of 18; an intervening weight gain increased risk substantially. These prospective data emphasize the importance of obesity as a determinant of coronary heart disease in women. After control for cigarette smoking, which is essential to assess the true effects of obesity, even mild-to-moderate overweight increased the risk of coronary disease in middle-aged women.

173 patients, aged 46.8 years on the average, were examined in the first 3 months after onset of angina pectoris. 97% of them presented at least one of risk factors (smoking, arterial hypertension, overweight, dyslipoproteinaemia), in 79% two or more risk factors were present simultaneously. A greater than 70% stenosis of one coronary artery was present in 51%, in 10% the stenosis was smaller than 70%, in 4% the coronary arteries were intact. In 131 patients without a history of myocardial infarction, vasospastic angina, overweight, and simultaneous presence of 3 or 4 risk factors occurred more frequently than in 42 patients with a history of myocardial infarction. In the first month, complications were registered only in patients with unstable angina pectoris (5 out of 41, i.e., 12%). During the later period of follow-up in 102 patients, complications occurred in 5% and complete clinical remission was registered in 35%. In patients with remission, positive exercise tests and haemodynamically significant stenoses of 2 or 3 coronary arteries were less frequently found on initial examination than in patients with sustained angina pectoris.

The relationship of socio-economic status (SES) indicators and coronary risk factors (RFs) with coronary heart disease (CHD) prevalence was examined in 5 620 subjects aged 20-60 years who participated in the Coronary Risk Factor (CORIS) baseline study. Education and income (with some exceptions in males) were strongly and inversely related to hypercholesterolaemia, low high-density lipoprotein cholesterol, hypertension, smoking, overweight and prevalence of angina pectoris. In contrast, type A behaviour was positively associated with higher income and education. Females showed stronger SES-RF relationships than males. Town-dwelling females were more likely to be smokers, and had a higher prevalence of angina pectoris and myocardial infarction. The lowest overall prevalence of RFs, angina pectoris and myocardial infarction was found in the professional and managerial categories for both males and females. The SES indicators had little or no independent effect on CHD prevalence in multivariate logistic analyses after inclusion of the standard RFs. We conclude that these indicators relate to RFs, and through them to CHD.

The aim of the present study was to relate the clinical course in patients after a first acute myocardial infarction with the site and size of infarct, estimated from standard enzyme measurements. One hundred and eight consecutive patients who suffered an acute myocardial infarction for the first time were followed-up after 30 months in general practice. Twenty-six patients had died and 8 had had another infarction. Sixty-two of the surviving patients had received treatment for ischaemic heart disease, usually for angina pectoris and less often for heart failure and arrhythmias. No correlation was found between ischaemic heart disease requiring treatment and the enzyme-estimated size or the site of the infarct. With anterior infarcts there was, however, an overweight of arrhythmias requiring treatment. Of the patients at work, 31% had changed job or job status because of ischaemic heart disease. At the end of the 30 month period, 50 patients were in functional class 1 and 2, and 32 in functional class 3 and 4 (New York Heart Association's classification).

We studied 17 severely obese subjects (age range 26 to 42 years), without hypertension, diabetes mellitus, angina, or clinical signs of heart failure or respiratory disease, and 16 age-matched control subjects. X-teleroentgenographic findings (transverse cardiac diameter and cardiothoracic ratio), blood pressure, and mechanocardiographic parameters were analyzed in both groups. By means of conventional simultaneous recordings of ECG, phonocardiogram, and carotid pulse (100 mm/sec), systolic time intervals were calculated as mean values from 10 beats in the morning. The following comparisons were made by means of analysis of variance: heart rate, preejection period (PEP), rate-corrected PEPI (PEPI), left ventricular ejection time (LVET), and QS2 interval (QS2); the latter two were both corrected for heart rate, respectively, as LVETI and QS2I and the PEP/LVET ratio. Abnormal x-ray data were shown in the obese group along with higher values for heart rate, PEP, PEPI, and PEP/LVET and a shorter LVETI; there were no differences in QS2I or blood pressure. There was a correlation between the amount of overweight and, respectively, transverse cardiac diameter (r = 0.84), heart rate (r = 0.69), PEP (r = 0.49), PEPI (r = 0.59), LVETI (r = -0.61), and PEP/LVET ratio (r = 0.72). A correlation was also found between transverse cardiac diameter and PEP/LVET (r = 0.67). We conclude, therefore, that abnormalities in the mechanocardiographic parameters are related to cardiac enlargement, suggesting a preclinical cardiac dysfunction secondary to chronic cardiocirculatory overload in severe obesity. Thus systolic time intervals appear to be affected by preclinical abnormalities of cardiac performance in these subjects.
