The results presented above indicate that the risk factors associated with the development of coronary heart disease in women are not that different than those identified for men. It is encouraging to note that while the prevalence of hypertension in women has not changed over the past twenty years, the proportion of treated hypertensive women has increased dramatically and the proportion with controlled blood pressure has doubled since 1960. It is also encouraging to note that the number of adult women who smoke cigarettes has decreased since 1960, but the number of young girls who smoke has increased at an alarming rate. It has been noted by researchers that among women who smoke, the number of cigarettes smoked per day has increased from the 1950s to the present. From the Framingham data it can be seen that womens' serum cholesterol level increases substantially with age and women should take steps to eat a healthy low-saturated fat, low cholesterol diet in order to maintain a low blood cholesterol level. It has been shown from the Framingham Study data that although the same risk factors operate in men and women, the standard risk factors do not explain the marked differences in morbidity and mortality from heart disease between the two sexes. We must continue to study the epidemiology and biology of coronary heart disease in women both to better understand the disease process in women and to understand the large sex differential for CHD in most westernized countries.

A study of patients with a stable course of bronchial asthma (BA) has confirmed the absence of a significant bronchodilating effect of nifedipine during an acute drug test (a single sublingual administration of the drug at a dose of 20 mg). Preliminary administration of nifedipine at a dose of 20 mg was noted to result in the prolongation of a bronchodilating effect of salbutamol inhaled at a dose of 200 micrograms, not influencing a degree of its expression. it has been assumed that prolonged use of nifedipine would result in reduced requirements of BA patients in inhalation sympathomimetics. This therapeutic trend especially holds promise for middle aged and aged BA patients with concomitant CHD, arterial hypertension. Reduced requirements in sympathomimetics in them would lead to the reduction of risk of iatrogenic exacerbations of cardiovascular diseases.

Our review focuses on all articles in the English language that provide sufficient data to calculate a relative risk or odds ratio for CHD at different levels of physical activity. The inverse association between physical activity and incidence of CHD is consistently observed, especially in the better designed studies; this association is appropriately sequenced, biologically graded, plausible, and coherent with existing knowledge. Therefore, the observations reported in the literature support the inference that physical activity is inversely and causally related to the incidence of CHD. The two most important observations in this review are, first, better studies have been more likely than poorer studies to report an inverse association between physical activity and the incidence of CHD and, second, the relative risk of inactivity appears to be similar in magnitude to that of hypertension, hypercholesterolemia, and smoking. These observations suggest that in CHD prevention programs, regular physical activity should be promoted as vigorously as blood pressure control, dietary modification to lower serum cholesterol, and smoking cessation. Given the large proportion of sedentary persons in the United States (91), the incidence of CHD attributable to insufficient physical activity is likely to be surprisingly large. Therefore, public policy that encourages regular physical activity should be pursued.

Prophylactic examination of the population in a district of a city out-patients clinic was performed. Altogether 689 persons (298 men and 391 women) aged 16 to 64 were examined. A great prevalence of chronic non-communicable diseases (CND) and common risk factors were revealed: CHD in 16.7% of the examinees, cerebral changes in 0.6%, diabetes mellitus in 3.9%, chronic bronchitis in 9.3%, arterial hypertension (AH) in 29.6%, smoking in 26.1%, disturbed carbohydrate tolerance in 15.7%, hypercholesterolemia in 13.5% and excess body mass in 35.5%. In 40% of the patients with AH it was combined with other chronic diseases necessitating a multidisciplinary approach to CND control in the patients with AH. The study showed that the population was not ready enough for prophylactic examination.

In over 30 years of surveillance of 2873 women, 574 developed initial clinical manifestations of CHD. A number of antecedent metabolic risk factors proved atherogenic, including blood lipids, glucose tolerance, uric acid, and menopause. Serum total cholesterol predicts as strongly in women as in men. The predictive power of cholesterol is strengthened when the total cholesterol is partitioned into its atherogenic LDL and protective HDL fractions. Contrary to the case in men, triglyceride may be a contributor to risk in older women. A total-to-HDL cholesterol ratio exceeding 7.5 equalizes the risk in men and women. Impaired glucose tolerance also eliminates the female CHD risk advantage over men, conferring a three-fold increased risk. Serum uric acid, although lower in women than in men, is equally predictive in the sexes. Central obesity confers an increased CHD risk in women and predisposes to diabetes, hyperuricemia, hypertension, and an unfavorable LDL/HDL cholesterol ratio. A combination of obesity, low HDL cholesterol, and impaired glucose tolerance predisposes especially. Age-adjusted risk of CHD is increased two- to threefold compared to pre menopausal women, even when induced surgically without removing the ovaries. It is not clear whether post menopausal estrogen replacement eliminates this excess risk. Fibrinogen is higher in women than in men, and is increased with hypertension, diabetes, hypercholesterolemia, high hematocrit, and cigarette smoking. At any level of multivariate risk, fibrinogen added to the CHD risk in women.

The results of a prospective 5-year survey of workers and employees at a computer manufacturing enterprise were summed up. The true prevalence of CHD (11.7% of examinees), arterial hypertension (16.5%), and risk factors of these diseases were established. A scheme of controlled therapy of CHD and arterial hypertension was developed and tested. The annual economic effect of the survey was 4038 rub. per 1000 examinees.

The paper presents the results of the study of medical impact of AUCPAHP. The study was performed in an organized population comprising 43197 males aged 40-54 years, including an intervention group of 23378 subjects and a control group of 19819. The active, mainly secondary prevention of arterial hypertension in 12 collaborative centres during 3-5 years has caused a decrease in overall mortality in the intervention group by 17.3% compared with that in the control group, in stroke mortality by 52.4% and non-fatal MI morbidity by 23.9%. CHD mortality has turned out to be practically equal in the two groups.

Contributors to CHD include atherogenic personal attributes, living habits which promote these, signs of preclinical disease, and host susceptibility to these influences. Atherogenic traits include the blood lipids, blood pressure, and glucose tolerance. High LDL cholesterol is positively and high HDL cholesterol inversely related to CHD incidence. Hypertension, whether systolic or diastolic, labile or fixed, casual or basal, at any age in either sex contributes powerfully to coronary heart disease. The impact of diabetes on CHD is greater for women than for men and varies according to the level of the foregoing risk factors. The faulty life-style is typified by a diet excessive in calories, fat, and salt, a sedentary habit, unrestrained weight gain, and cigarettes. Alcohol used in moderation may be beneficial. Oral contraceptives worsen atherogenic traits and, when used for long periods beyond age 35 in conjunction with cigarettes, predispose to thromboembolism. Type A persons with an overdeveloped sense of time urgency, drive, and competitiveness develop an excess of angina pectoris. Men married to more highly educated women are at increased risk, as are men married to women in white-collar jobs. Preclinical signs of a compromised coronary circulation include silent MI, ECG-LVH, blocked intraventricular conduction, and repolarization abnormalities. Exercise ECG may elicit still earlier evidence. Measures of innate susceptibility include a family history of premature cardiovascular disease, diabetes, hypertension, and gout. Optimal prediction of CHD requires a quantitative combination of risk factors in multiple logistic risk formulations that identify high-risk persons with multiple marginal abnormalities. Preventive management should also be multifactorial.(ABSTRACT TRUNCATED AT 250 WORDS)

The effects of long-term (10 years) management at a special out-patient hypertension clinic with respect to dropout rate, side effects, blood pressure (BP) control, target organ involvement, prognostic factors and cardiovascular morbidity have been studied in 686 middle-aged male hypertensives. The impact of antihypertensive treatment, as one ingredient of multiple risk factor intervention, on mortality and morbidity in an urban, male population have been analysed. The hypertensive patients were derived from a random sample of men, aged 47-54 years at entry, constituting the intervention group (n = 7,455) of a multifactorial primary prevention trail. The whole population sample was studied regarding the effect of treatment on morbidity. The 10-year drop-out rate (declined follow-up/unknown reasons) was low (5%) being highest during the first year. The frequency of severe adverse drug effects was low (3% per year) after the initial period when treatment was started. An acceptable BP reduction was achieved in the majority of patients, but in many cases first after a few years' treatment and requiring combination drug therapy. Two-thirds of the patients achieved the goal BP (i.e. less than 160/95 mm Hg). These results are attributed to the organisation of the clinic and emphasise the need for frequent check-ups during the early phase of treatment and an easy accessibility to nurses and physicians. Except for a significant regression of ST- and T-wave changes on the conventional ECG during the first treatment year signs of heart (conventional ECG, chest X-ray) and kidney (albuminuria, serum creatinine) involvement remained unchanged or increased slightly during follow-up. Angina pectoris (AP), intermittent claudication (IC) and congestive heart failure (CHF) were common complications. The prevalence increased steadily with an average annual incidence of 1.3% (AP), 0.6% (IC) and 0.6% (CHF). ECG signs indicating subclinical heart disease were risk factor for AP and CHF. Smoking was an independent risk factor for any one of these cardiovascular disorders. The 10-year incidence of total mortality was 11.1%, and of CHD and stroke morbidity 12.2% and 4.1%, respectively. Independent risk factors (entry variables) for CHD were diastolic BP, smoking, serum cholesterol, AP and proteinuria. A previous stroke, smoking and proteinuria were independently associated with stroke morbidity. Hence, the risk factor pattern was similar to that known to operate in the general population.(ABSTRACT TRUNCATED AT 400 WORDS)

Coronary heart disease, the primary health problem in western life, is caused by the interaction of multiple factors. Absolute proof of the contributing role of physical inactivity is not possible owing to the complexity of the CHD problem and the infeasibility of a definitive clinical trial because of logistical and economic constraints. Despite limitations, existing epidemiologic studies strongly suggest, but fall short of proving, the concept that habitual physical exercise offers partial protection against primary or secondary events of CHD and associated mortality. However, experimental data support this hypothesis and provide evidence of possible mechanisms responsible for the protection. The available epidemiologic data also suggest that physical inactivity is probably not as potent an individual risk factor as elevated serum cholesterol levels, hypertension, and cigarette smoking, and that the protective effects of exercise may be overwhelmed by high levels of these major risk factors. On the other hand, there is some evidence that exercise may attenuate other risk factors both directly and through associated weight reduction. Epidemiologic studies also suggest a dose response relationship between physical activity and rates of CHD. About 2000 kcal per week of moderate intensity, dynamic, endurance-type of exercise (such as walking or jogging about 20 miles per week) or at least one hour of intermittent hard physical labor are required to obtain the optimal effect of exercise on coronary heart disease rates. Experimental studies suggest that this amount of exercise should provide sufficient stimulus to favorably alter blood HDL cholesterol levels and perhaps other CHD risk factors, especially if there is an accompanying reduction in weight. Possible mechanisms for the protective effects of exercise against CHD are illustrated in Figure 1. Insistence on final experimental proof prior to prudent medical practice or public health policy on physical inactivity or other coronary risk factors indicates a lack of understanding of the nature of scientific proof and evidence required for health actions.(ABSTRACT TRUNCATED AT 400 WORDS)
