Carminomycin chemotherapy of the patients with malignant tumors is often complicated with cardiopathy which is sometimes assymptomic and registered only electrocardiographycally. Chemotherapy on the background of reparative regeneration stimulators from the series of synthetic pyrrimidine derivatives, such as methyluracyl for oral use and a soluble salt of methyluracyl for parenteral administration significantly decreased the rate of the cardiotoxic complications and promoted a decrease in their level. The use of methyluracyl and its soluble salt did not decrease the therapeutic effect of carminomycin. Methyluracyl and its soluble salt may be recommended for prophylaxis of cardiotoxic complications in chemotherapy of malignant tumors with carminomycin.

In 1972 the Stanford Heart Disease Prevention Program launched a three-community field study. A multimedia campaign was conducted for two years in two California communities (Watsonville and Gilroy), in one of which (Watsonville) it was supplemented by an intensive-instruction program with high-risk subjects. A third community (Tracy) was used as a control. The campaigns were designed to increase participants' knowledge of the risk factors for cardiovascular disease, to change such risk-producing behavior as cigarette smoking, and to decrease the participants' dietary intake of calories, salt, sugar, saturated fat, and cholesterol. Results of a sample survey indicate that substantial gains in knowledge, in behavioral modification, and in the estimated risk of cardiovascular disease can be produced by both methods of intervention. The intensive-instruction program, when combined with the mass-medica campaign, emerged as the most effective for those participants who were initially evaluated to be at high risk. The results after two years of intervention are reported for effects on knowledge and behavioral change for the total participant samples and for the high-risk subsamples in each of the three communities.

To assess the effect of long-term lithium therapy on cardiac arrhythmias and cardiovascular performance, extended ambulatory electrocardiographic monitoring was performed in 12 patients, and rest and exercise electrocardiograms in 10 of 12, before and during lithium therapy. Lithium increased the frequency of premature ventricular contractions in three patients, decreased it in one, and produced no change in eight. Three of four patients with atrial arrhythmias showed improvement during lithium therapy. Exercise performance was unchanged. Although 7 of the 12 patients manifested T wave flattening in the resting electrocardiogram, none had S-T segment displacement at rest or on treadmill exercise. Before lithium therapy, arrhythmias on exercise included premature atrial contractions in four patients, ventricular arrhythmias in four (premature ventricular contractions in four, with couplets in two and with ventricular tachycardia in one). During lithium therapy, exercise did not provoke premature atrial contractions or ventricular tachycardia in any of the patients, but three patients had premature ventricular contractions (with couplets in one case). We conclude that lithium at therapeutic levels may precipitate or aggravate ventricular arrhythmias. When administered to patients with heart disease, factors that interfere with renal clearance of lithium (heart failure, salt restriction, long-term diuretic therapy) must be recognized and doses must be adjusted accordingly. Careful follow-up and electrocardiographic monitoring are advisable if lithium is to be used in the presence of ventricular arrhythmias. Cardiovascular performance as assessed by treadmill exercise testing was not affected by long-term lithium therapy.

185 cases of pregnancy in cardiac patients followed since 1965 included 48 therapeutic abortions, 20% premature deliveries, 36 Caesarean sections, and 101 vaginal deliveries. Abortions, done by dilatation and curettage or hysterotomy, usually with tubal ligation, were performed in class III or IV cardiopathies (inoperable or relapses) and in those with decompensation in first trimester or in previous pregnancies. 10 women were operated by closed heart technique during pregnancy, usually mitral valvotomy procedures. Treatments during pregnancy included bed rest, hospitalization 2 weeks before term, low salt diet, diuretics, digitalis, calcium heparin, sedatives, and antibiotics. Prognosis depends on severity and nature of the cardiopathy, age, parity, obstetric history, and the patient's ability to follow instructions. Deliveries were originally done by Caesarean section if sterilization was planned, but recently tubal ligation is done within 2 months postpartum. 55% of the vaginal deliveries were by forceps under local anesthesia; 40% by natural chiildbirth. 4 neonates died, and 36 were premature or dysmature. Lactation was suppressed by ethinyl estradiol in almost all patients.

Round heart disease in turkey poults has been associated with high levels of dietary salt and when it occurs in the field recommendations often include a reduction in the level of dietary salt. Poults fed diets containing up to 1.5% salt and 1.5% sodium did not exhibit signs of round heart disease. A high mortality rate occurred with poults fed a salt-free diet. Post-mortem analysis generally revealed enlargement of the kidneys with urates; exudate was present in both abdominal and thoracic air sacs. Growth trials indicated that in order to maintain an optimum feed:body weight gain ratio, corn-soybean diets should contain at least 0.1--0.2% supplemental salt, and at least 0.2--0.3% salt when growth rate is considered. Minimum salt levels could not be reduced further by adjustment of the total dietary sodium:chloride ratio to unity.

This investigation evaluated the effect of a peer-education program on preventing cardiovascular disease in older persons. Peer leaders at two urban senior housing residences were provided with training on cardiovascular disease and its risk factors, strategies to reduce the risk factors, and communication skills. Baseline and follow-up data were collected on residents at the two intervention and two control sites. The dependent variables were knowledge of cardiovascular disease risk factors; perceived self-efficacy to reduce calories, dietary fat and salt intake, to lose weight, to stop smoking, and to exercise regularly; and self-reported cardiovascular risk behaviors. Analysis of individual change scores between baseline and follow-up surveys showed a statistically significant increase in overall knowledge of heart disease, dietary self-efficacy, and exercise self-efficacy for the intervention group compared with the control group. This program appeared to benefit the individuals who lived in housing residences where the peer educators also resided.

Elevated blood pressure (BP) is of special clinical significance because of its association with pathophysiologies such as heart disease, renal failure, and stroke. We described the development of a protocol for use with hypertensive rats in which prepubertal exposure to a high salt (8% NaCl) diet results in a pathophysiological syndrome including rapid increase in BP, failure to maintain normal weight gain, renal damage, cerebrovascular lesions, and early mortality. These phenomena are described for the inbred spontaneously hypertensive rat (SHR), and for reciprocal F1 hybrids of a cross between SHR and the Dahl salt-sensitive (SS/Jr) inbred strain. The study with reciprocal F1s revealed striking effects of maternal environment on pathophysiological response to a high salt diet. F1s nurtured by SHR mothers weighed less at 35 days of age, and after exposure to the high salt diet suffered more rapid BP increases, greater incidence of stroke, body weight loss, and mortality, than F1s nurtured by SS/Jr dams. These results suggest that maternal mediation of the nutritional status of the animal may play an important role in determining susceptibility to elevated BP and subsequent pathophysiology associated with exposure to a high salt diet. The implication of these findings for human hypertension is briefly discussed.

In affluent nations, there has been an increasing awareness of the links between diet and the incidence of chronic diseases such as heart disease, hypertension and cancer. In some of these countries, this has led to improvements in the dietary profiles of the community and its health-related status. Studies of random samples of the Australian population carried out in the last decade or so have shown a downward trend in the consumption of total and saturated fats and salt and an increase in polyunsaturated fat and fibre. However, detailed assessment of food consumption patterns reveal that the changes in dietary patterns relate predominantly to improvement in choice within food categories rather than a fundamental change in the relative amounts of foods consumed across categories such as meats, dairy foods, cereal grains and fruits and vegetables. The surveys show that knowledge about the links between diet and disease is encouragingly high in most sectors of the Australian community as is concern about the healthiness of the food supply but time constraints, the perception that "healthy" foods are boring foods, lack of information on packaging and family pressures were seen as major barriers to dietary change. A further barrier is lack of knowledge about the balance of foods required and in particular, the value of cereal foods. Analysis of the dietary data show that further significant improvements in the dietary profile are only likely to accrue from a fundamental change in the relative use of the major food categories.

New Zealand food shoppers' nutrition and food concerns and attitudes to cholesterol screening were assessed during four consecutive surveys. Over 1000 shoppers were interviewed during each survey, as part of the evaluation of the Heart Food Festival in 1988-89. Over two thirds of the respondents reported that they usually read the ingredients label on food products. Over a third were concerned about the presence of additives in foods (36 per cent), along with fat (27 per cent), salt (18 per cent), sugar (14 per cent) and fibre (5 per cent). Over half indicated that reductions in fat intake would make their diets healthier. One in five reported they were aware of the New Zealand nutrition guidelines. Only one third of respondents could correctly identify the bottom row of the healthy food pyramid. Almost one in eight respondents knew their cholesterol levels and a further two thirds wished to know them. Few differences were observed between the responses of early and late school leavers. In contrast, pronounced differences were associated with gender and the respondents' age groups. The results suggest that awareness of links between nutrition and heart disease is widespread. Educational and empowerment strategies are required to translate such awareness into dietary change.

In the light of the proposal that dietary salt intake should be reduced as a community health care measure designed to lower blood pressure and consequently mortality and morbidity from stroke and heart disease, the evidence that there is a link between salt intake and blood pressure is reviewed. In addition the effects of salt restriction on mild hypertension are surveyed as is the feasibility of sustaining a community-based campaign to reduce salt intake. It is concluded that whilst it would be possible to mount a concerted health care programme directed towards lowering the salt intake of the general population the benefits in terms of blood pressure would be extremely small. The impact on stroke and heart disease is unknown and possible adverse effects have not been examined.
