Heart disease continues to be a major cause of disablement and death in Canada. Elevated serum cholesterol concentrations, hypertension and cigarette smoking are among the standard risk factors associated with ischemic heart disease. Research attention has also been directed at the role of behavioural factors in the development of atherosclerosis and myocardial infarction. Experimental findings support a conceptual approach to the interplay of psychologic stress, the type A "coronary"-prone behaviour pattern and pathophysiologic mechanisms that have been implicated in the development of coronary artery disease. It is concluded that type A behaviour and stress contribute substantially to the pathogenesis of cardiovascular disease. However, assessment of the manner in which these two variables influence the pathophysiology of ischemic heart disease requires further research, with systematic examination of physiologic and biochemical processes. Potential strategies for modifying type A behaviour are reviewed. However, unequivocal support for the preventive efficacy of behavioural approaches must await future research.

A pronounced decline in blood pressure levels of hypertensive patients occurred in each of three rural Minnesota communities 1 to 2 years after the inception of community programs to control high blood pressure in these populations. An experimental hypertension clinic was established in one community to integrate a nurse practitioner into a physician-supervised program of long-term patient management. In the community with this innovative, partially subsidized practice arrangement, we observed declines in diastolic pressures of hypertensives. However, comparable degrees of blood pressure reduction occurred in the two other communities, with traditional solo or small group practice arrangements, where intervention was limited to detection and referral alone or was supplemented with continuing education of physicians in the management of hypertension. The evaluation of these three community programs suggests, among other conclusions, that this innovative community model for hypertension control, based on the recommendations of the Inter-Society Commission for Heart Disease Resources, contributed to favorable short-term blood pressure outcomes for the community. The observation of similar overall outcomes as measured by blood pressure reduction in all three communities was unexpected; the clinic's impact appears to have been matched by the effectiveness of screening and referral, alone or with continuing education, in the two other communities.

A study about gout associated with hypertension, diabetes, ischemic cardiopathy and different alterations in the sanguineous levels of lipids was conducted on 80 patients of the Rheumatology Service at the National Institute of Cardiology in Mexico City. We found abnormal levels of tryglicerids in the blood of 55% of the patients and a high level of cholesterol in only 5%. In 27% of the patients, some alteration showed in the carbo-hydrates methabolism, and in 22,5% of them we found systemic arterial hipertension. Slight ischemic cardiopathy was showing in a 37% of the patients, but uric acid level in blood seemed to be of little importance for the frequency, type or severity of the coronary heart disease. We made a comparison between the results we obtained through these studies and those found among the Mexican population and with information found in international medical publications.

Cardiovascular conditions of 27 patients with primary hyperparathyroidism have been examinated. Hypertension has been found to be the only alteration significantly present (33,33% of patients), while heart disease are uncommon. Hypertension is often present without concomitant disease of the kidney. Blood pressure became normal in only one case over nine (11,11%) after parathyroidectomy.

During a review of all cases of heart disease, including hypertensive cardiac failure, seen in Botswana during a period of sixteen months by one Specialist Physician observer, the importance of Idiopathic Cardiomyopathy as the commonest cause of cardiac failure clearly emerged. The aetiology of this condition and its relationship to hypertension and other factors causing an increased load on the myocardium are discussed. Viral myocarditis is presented as a separate entity, possibly playing a part in causation.

Four Black South African patients, representative of a larger group, are described in detail. The common features were long periods of observation, multiple hospital admissions in both normotensive and hypertensive cardiac failure, hypertensive retinopathy and good renal function. All had been diagnosed as having cardiomyopathy. Two of the patients in a normotensive phase became hypertensive after responding to therapy for heart failure. One patient with malignant hypertension showed the features of idiopathic cardiomyopathy at necropsy. These cases are regarded as evidence in favour of the hypothesis that many cases of cryptogenic heart disease (cardiomyopathy, congestive cardiomyopathy, idiopathic cardiomegaly) are in fact cases of hypertension presenting with normotensive cardiac failure.

The authors placed Swan-Ganz catheters in 11 preterm and 2 term infants with severe cardiopulmonary distress. The infants ranged in weight from 1100-4000 g. The procedure was performed in the neonatal ICU by jugular venous cutdown. Intracardiac pressures and oxygen saturations were measured in each chamber entered. The authors also evaluated the presence of right to left shunting through the patent ductus arteriosus and assessed the degree of pulmonary arterial hypertension. In 5 hypoxemic infants, the authors found a patent ductus arteriosus with pulmonary hypertension. Intermittent measurement of PAP served as a guide to further therapy. In 2 infants, the unexpected diagnosis of cyanotic congenital heart disease was made. The placement of flow directed pulmonary arterial catheters in critically ill infants can be performed safely at the bedside and can provide useful diagnostic and therapeutic information.

The most important advancement in perinatology during the past few years has been the possibility to selectively establish a criterion to judge high risk pregnancies, which still represent the great majority of cases of materno-infant morbimortality. Social, economic, and cultural factors, age, biological antecedents of the mother, previous pregnancies, and medical history, have all a great influence in the evaluation of gestation. Through the years several models have been constructed to evaluate high perinatal risks; excluding complications due to danger of congenital abnormalities only 19% of women are exposed to high risk pregnancy. Among prenatal risk factors the most common are toxemia, chronic hypertension, severe cardiopathy, and diabetes; risk factors that may become more evident during delivery or shortly before it are toxemia again, premature rupture of membranes, meconial amniotic fluid, and abnormal presentation.

A comparison of health status between 779 Seventh-day Adventists, who have a strong commitment to heal-related life styles, and two other groups of people--8363 persons referred by general practitioners and 9825 volunteers--was made. The Seventh-day Adventists showed less impairment of systolic and diastolic blood pressures, of plasma cholesterol and plasma urate concentrations, and of lung ventilatory capacity; and less obesity at most specific ages. With increasing age, the level of breathlessness, reported heart disease, hypertension, and hypertensive and diuretic therapy in this sample approached that of the comparative groups, possibly because of natural attrition of high-risk persons in the latter. Depression, sleeplessness, use of sedatives and tranquillizers were lower in the Seventh-day Adventists; although, once again, a drawing together of the three groups in older age categories was evident. It is concluded that the life style of Seventh-day Adventists is conducive to lessened morbidity, delayed mortality, and decreased call on health services in comparison with the general population.

Eighteen patients with idiopathic optic neuropathy lacked symptoms and signs of cardiovascular and cerebrovascular disease, especially when compared to three groups of patients with sudden visual loss caused by retinal infarction, transient ischemia, and cerebral infarction. Many patients in the latter groups had hypertension, carotid bruits, heart disease, transient ischemic attack, and stroke. But among the patients with ischemic optic neuropathy, hypertension was the only evidence of cardiovascular disease, affecting 44% of the patients. We argue that, in many cases, ischemic optic neuropathy represents a direct and early complication of hypertension arterial disease affecting small arterioles supplying the anterior part of the optic nerve. The pathologic process may thus be similar or identical to lacunar infarction of the brain.
