In minorities, as in the general population, hypertension is taken seriously because it is a risk factor for cardiovascular disease. Until recently, our understanding of the role that hypertension plays in the heart disease seen in minorities has been limited by a paucity of prospective data regarding the prevalence, natural history, and pathophysiology of the disease process in minority populations. In the last few years large-scale epidemiologic studies and well-controlled clinical studies alike have confirmed usually high rates of hypertension-related morbidity and mortality in minorities, particularly blacks and Hispanics. The severity of end-organ damage, both cardiac and renal, that is seen in these patients--especially when coupled with the severe cerebrovascular damage that is also more common in black and Hispanic hypertensives--mandate that more effective public health measures be taken to reduce the incidence of hypertension in these patient populations. Because hypertension is usually without significant clinical symptoms, noncompliance with drug therapy and high dropout rates are common in all patient populations. They are strikingly higher in inner-city populations, however, where illiteracy, poverty, homelessness, and high rates of chemical dependency combine to exacerbate an already serious problem in treating hypertensive patients. Inner-city patients are, increasingly, black and Hispanic patients, and these patients are more likely to be underinsured or uninsured, to be functionally illiterate in English, to be disinclined to seek health care, and to be less capable of following a prescribed regimen than the populace as a whole. The nature of the therapeutic regimen itself is probably the most important determinant of compliance, and compliance with drug therapy will be improved if the clinic chooses a simplified drug regimen and avoids drugs that produce intolerable side effects. Once-a-day--or, with transdermal clonidine, one-a-week--single-drug therapy may not be possible in all patients, but multiple drug therapy and multiple daily dosing schedules should be avoided wherever possible.

The aim of this study was to describe the experience of coronary artery bypass surgery (CAB) from the patient's perspective. A grounded theory method was used to explore the postoperative experiences of eight men and one woman following CAB surgery. The major process individuals engaged in following CAB surgery was seeking normalcy which involved three conceptual stages: surviving, restoring, and being fixed. Some individuals sought other explanations for the symptoms accompanying heart disease. An understanding of patient experiences regarding the nature of cardiovascular disease through the experience of surgery regimens may contribute to the assessment and intervention strategies used by health care providers in the postoperative care of these patients.

Central Europe comprises a heterogeneous group of some 120 million persons from 11 countries which differ greatly in food availability and preferences. The region has undergone dramatic changes in food consumption patterns and in the patterns of nutritionally related diseases. The changes in the political situation in central Europe have provided a unique natural experiment which allows the study of the effects of different eating behaviors on health within a genetically homogeneous population and an analysis of the time frame in which effects can be seen at the national level. This is in particular the case for the FRG and the GDR. Epidemics of nutritionally related disease have arisen, including cardiovascular disease, cancers of the colon and breast and obesity. These occur at very different rates in neighboring countries. Furthermore, unknown factors, probably including food-hygienic factors and methods of storage and preparation, have resulted in drastic reductions in the rates of stomach cancers in all countries. These have only recently been detected, as no systematic nutritional surveillance systems are currently in effect in Europe. Due to the chronic nature of the diseases in question, we are noticing too little, too late. Food patterns provide a realistic and sensitive predictor of disease incidence. They are timely enough to detect changes before they are reflected in a diminished health status of the population or specific risk groups. Details on the patterns of intake and secular trends, as far as they are available for individual countries, reveal that eating behavior is quite labile and subject to dramatic changes within decades. The current information status does not allow a closer examination of specific population groups, such as the behavior of children or the elderly, the intakes of pregnant or breast-feeding women, or the eating behavior of men at high risk of heart disease. The foundations of a European nutrition surveillance system need to be laid, to make possible the timely detection of high-risk-related changes in food consumption, unfavorable trends and early signs of nutritionally related epidemics. The regular, standardized assessment of eating patterns will be an important building stone in such a system.

Patients with diabetes mellitus are particularly vulnerable to cardiovascular disease. Although both the macrovascular and microvascular complications are present in patients with diabetes alone, they are particularly severe in patients with both diabetes and hypertension. While there is no doubt that a primary diabetic cardiomyopathy occurs with functional consequences, considerable evidence--both in humans and in experimental animal models--points to hypertension as of critical importance in the pathogenesis of severe pathological and symptomatic diabetic heart disease. In hypertensive-diabetic cardiomyopathy, the histopathologic myocardial damage has been attributed to hypertension, while the myocellular dysfunction has been attributed to diabetes. Together, the consequences to the myocardium are devastating. Strict control of the hypertension and diabetes mellitus, along with prevention of the microvascular consequences of both conditions, may have an ameliorative effect on the subsequent development of diabetic heart disease.

318 records of male workers, 169 Spanish and 149 Arab were retrospectively studied in 1987 at the "Gabinete de Seguridad e Higiene en el Trabajo" (Council for Safety and Hygiene in the Workplace) in Ceuta in order to prove the hypothesis that 2 different ethnic groups living in the same geographic area have a non-equal distribution of cardiovascular risk factors. The Spanish group showed a higher prevalence in blood hypertension, diabetes, glucose intolerance, obesity and alcohol intake, compared to the Arab group. Smoking and high levels of seric cholesterol were similar in both groups, however, medium levels of seric cholesterol were lower in the Arab group. Family histories of cardiovascular disease were very rare in the latter mentioned group. These observations suggested a major predisposition to ischemic cardiopathy in the Spanish group.

The evidence that ETS increases risk of death from heart disease is similar to that which existed in 1986 when the US Surgeon General concluded that ETS caused lung cancer in healthy nonsmokers. There are 10 epidemiological studies, conducted in a variety of locations, that reflect about a 30% increase in risk of death from ischemic heart disease or myocardial infarction among nonsmokers living with smokers. The larger studies also demonstrate a significant dose-response effect, with greater exposure to ETS associated with greater risk of death from heart disease. These epidemiological studies are complemented by a variety of physiological and biochemical data that show that ETS adversely affects platelet function and damages arterial endothelium in a way that increases the risk of heart disease. Moreover, ETS, in realistic exposures, also exerts significant adverse effects on exercise capability of both healthy people and those with heart disease by reducing the body's ability to deliver and utilize oxygen. In animal experiments, ETS also depresses cellular respiration at the level of mitochondria. The polycyclic aromatic hydrocarbons in ETS also accelerate, and may initiate, the development of atherosclerotic plaque. Of note, the cardiovascular effects of ETS appear to be different in nonsmokers and smokers. Nonsmokers appear to be more sensitive to ETS than do smokers, perhaps because some of the affected physiological systems are sensitive to low doses of the compounds in ETS, then saturate, and also perhaps because of physiological adaptions smokers undergo as a result of long-term exposure to the toxins in cigarette smoke. In any event, these findings indicate that, for cardiovascular disease, it is incorrect to compute "cigarette equivalents" for passive exposure to ETS and then to extrapolate the effects of this exposure on nonsmokers from the effects of direct smoking on smokers. These results suggest that heart disease is an important consequence of exposure to ETS. The combination of epidemiological studies with demonstration of physiological changes with exposure to ETS, together with biochemical evidence that elements of ETS have significant adverse effects on the cardiovascular system, leads to the conclusion that ETS causes heart disease. This increase in risk translates into about 10 times as many deaths from ETS-induced heart disease as lung cancer; these deaths contribute greatly to the estimated 53,000 deaths annually from passive smoking. This toll makes passive smoking the third leading preventable cause of death in the United States today, behind active smoking and alcohol.

Pulmonary function is known to be related inversely to incidence of coronary heart disease, congestive heart failure, chronic obstructive lung disease, lung cancer, and death from all causes. Reasons for some of these associations are poorly understood. Relationships between cardiovascular disease risk factors and pulmonary function were examined in 5,115 18- to 30-year-old black and white male and female participants in the study of Coronary Artery Risk Development in Young Adults (CARDIA). Forced expiratory volume in 1 s adjusted for height (FEV1/Ht2) was significantly lower in smokers than nonsmokers and in persons who reported shortness of breath; FEV1/Ht2 was correlated positively with a history of strenuous physical activity, duration of exercise on the treadmill, and high-density lipoprotein cholesterol. It was associated negatively with skinfold thicknesses, serum triglycerides, fasting serum insulin, and the Cook Medley scale of hostility. The association between pulmonary function and heart disease risk may reflect associations with physical fitness, vigor, fatness, and lipid profiles, as well as with cigarette smoking.

Family histories were obtained from 123 patients with rheumatoid arthritis and 152 patients with other musculoskeletal complaints. The subjects were female patients aged 40 years or more seen at the Arthritis Clinic of the State University of New York Health Science Center at Brooklyn between October 1985 and February 1986. It was found that death due to heart disease or stroke was more common (adjusted p less than 0.02) in the mothers of patients with rheumatoid arthritis than in the mothers of control patients, and that heart disease was also reported to be more common in these mothers (adjusted p less than 0.005). Thus, it is possible that cardiovascular disease at least partially accounts for the previously noted (J Rheumatol 1986; 13:903-6) shorter life expectancy of the mothers of patients with rheumatoid arthritis.

The Honolulu Heart Program (HHP) is a prospective study of heart disease and stroke in Japanese-American men in Hawaii. Body weight, height, and subscapular and triceps skinfold thicknesses were measured by using standard methods at the baseline exam held in 1965-1968. The relationship of measures of body fatness to the 20-y follow-up for coronary heart disease (CHD) and stroke of these men was explored. Body mass index (BMI), subscapular skinfold thicknesses, and centrality index (subscapular skinfold thickness/triceps skinfold thickness) were predictors of CHD in this population, even after other risk factors were added to a multivariate model, indicating an independent contribution of body fat to CHD risk. Neither BMI nor centrality index was related to stroke. However, subscapular skinfold thickness was an independent predictor of stroke. The implications of these findings are that lifestyle changes that lead to an increase in obesity of Japanese men in Hawaii may increase risk for cardiovascular disease.

An epidemiological study was undertaken to determine whether the animal carcinogen, epichlorohydrin (ECH), produces cancer in man. A total of 863 workers with probable exposure to ECH at two chemical plants during 1948-65 were followed up for deaths up to 1983. Twenty years or more after first exposure the all cancer SMR was 112.2 (22 deaths) and the SMR for leukaemia was 500.0 (three deaths), which is statistically significant. All cancer, leukaemia, and most other causes of death were related to estimated levels of exposure to ECH, except violence. The most consistent (both plants) relation was between exposure level and heart disease. Overall, the heart disease SMR 20 years or more after first exposure was 39.2 (five deaths) for low exposure and 105.4 (17 deaths) for high exposure. Limited evidence of a cardiovascular disease relation to ECH production in one other epidemiological study is supported by this study. Allyl chloride used in the production of ECH may play a part. The relation of heart disease and exposure does not appear to be an artifact, although the fact that many other causes of death were also related to exposure argues against a causal relation.
