The aim of this study was to evaluate the usefulness of M-mode echocardiography as a non-invasive diagnostic tool when facilities for cardiac catheterization were not available. We used this technique to study 275 patients whose clinical diagnosis included hypertension, rheumatic heart disease, cardiomyopathy, peripartum cardiac failure, pericardial disease and some forms of congenital heart disease. Characteristic echocardiographic patterns made specific cardiac diagnoses possible and allowed a distinction to be made between clinically similar conditions. It is concluded that echocardiography is very useful in the African setting because it is safe and repeatable.

By means of a device system consisting of constituents of the SW-production and own developmental works in the factory Kombinat VEB Umformtechnik (combinate nationally owned enterprise transformation technology) for the first time ECG serial examinations were performed with the help of the mechanical ECG-analysis. The corrected orthogonal system of Frank with 3 leads served as deviation system. The ECG-registration was independently performed by function nurses. 1,720 male and female workers of this factory at the age of 21 to 59 years served as test persons. The ECG-registration lasted 20 sec., the whole time of examination including the changing of clothes and the way from the working place to the examination room did not last more than 4 to 8 min. As diagnosis programme served that one developed by Pipberger. The mechanical analysis resulted in 74.4% in a normal course of the electrocardiographic current curve. Among the pathological or abnormal ECGs (25.6%) prevailed the vegetative-functional heart diseases with 92%. Then followed the chronic ischaemic heart diseases with 7.9% and the hypertension with 5.1%. Diseases of the heart and the blood circulation established for the first time referred to 8.9%. Of them 5% needed control and 3.9% needed therapy.

All autopsies on Black patients who died of heart disease at Baragwanath Hospital were examined for the years 1959, 1960 and 1976. The commonest form of heart disease encountered in South African Blacks is undoubtedly hypertensive heart disease and by far the majority of these cases are of essential hypertension. There appears to have been a slight rise in the incidence of hypertension. Rheumatic heart disease is extremely common, and affects young people, who often have advanced valvular lesions by puberty. The incidence of idiopathic cardiomyopathy does not seem to have altered materially, although there has perhaps been a slight drop, which may be accounted for by the tendency of clinicians to place cases of congestive cardiac failure with mild hypertension in the hypertensive group rather than in the idiopathic cardiomyopathy group. There was a significant alteration in the incidence of myocardial infarction; in 1959 and 1960 these cases comprised less than 1% of all cardiac deaths but in 1976 they comprised nearly 12%. There has also been a dramatic fall in the incidence of cardiovascular syphilis.

A thorough search for the natural history of arteriosclerosis involving the cerebrum, aorta, and peripheral vessels has been made. The disease's rate of progress has been studied anatomically, clinically, radiologically, and plethysmographically. We conclude that arteriosclerosis is usually associated with other diseases such as diabetes, high blood cholesterol, and hypertension. Heart disease in particular is often the cause of the patient's death, rather than the peripheral arteriosclerotic disease itself. The usually slow development and course of arteriosclerosis indicate that its treatment is largely a medical problem. It seems important to control the various risk factors and to utilize surgical therapy to attack specific lesions which threaten the tissues. A thorough cardiovascular profile of the patient should be compiled and should include a glucose tolerance test and lipoprotein phenotyping.

In an attempt to assess cardiac risk in non-cardiac surgery, 1001 patients over 40 years of age who underwent major operative procedures were examined preoperatively, observed through surgery, studied with at least one postoperative electrocardiogram, and followed until hospital discharge or death. Documented postoperative myocardial infarction occurred in only 18 patients; though most of these patients had some pre-existing heart disease, there were few preoperative factors which were statistically correlated with postoperative infarction. Postoperative pulmonary edema was strongly correlated with preoperative heart failure, but 21 of the 36 patients who developed pulmonary edema did not have any prior history of heart failure. Nearly all of these 21 patients were elderly, had abnormal preoperative electrocardiograms, and had intraabdominal or intrathoracic surgery. In the absence of an acute infarction, bifascicular conduction defects, with or without PR interval prolongation, never progressed to complete heart block. Spinal anesthesia protected against postoperative heart failure but not against other cardiac complication. By multivariate regression analysis, postoperative cardiac death was significantly correlated with (a) myocardial infarction in the previous 6 months; (b) third heart sound or jugular venous distention immediately preoperatively; (c) more than five premature ventricular contractions per minute documented at any time preoperatively; (d) rhythm other than sinus, or premature atrial contractions on preoperative electrocardiogram; (e) age over 70 years; (f) significant valvular aortic stenosis; (g) emergency operation; (h) a 33% or greater fall in systolic blood pressure for more than 10 minutes intraoperatively. Notably unimportant factors included smoking, glucose intolerance, hyperlipidemia, hypertension, peripheral atherosclerotic vascular disease, angina, and distant myocardial infarction.

Twenty-two cases of sub-tentorium cerebral abscesses were observed in children. The first clinical symptoms were those of intracranial hypertension, disorders of consciousness, specially somnolence, fever and low general condition. Focal neurological signs were frequent but appeared later. A cerebral abscess should be suspected when such symptoms occur in children with heart disease or with respiratory infection. Simple investigations like examination of the fundi, X-ray of the skull and EEG give valuable clues. In case of such a clinical picture, lumbar puncture is useless and often dangerous. The best diagnostic test is a cerebral scintigram.

Examination of the cardiovascular apparatus (cv) of 25 acromegalic patients revealed an increased incidence of cardiovascular pathology as against normal individuals. Acromegalic patients with arterial hypertension (AH) show a twice higher incidence of ischemic cardiopathy, cardiomegaly with obvious or latent cardiac failure, arrhythmias, which frequently lead to death. The uncertain pathogeny of cardiomyopathy implied: hypoxia due to heart hypertrophy (over 500 g and increased cross-section of the fibre to over 26/mu), adrenergic deficiency resulting from increased protein synthesis and decrease in thyrosine, a precursor of myocardic cathecolamines. The increased incidence of coronary pathology is favoured in acromegalic patients by diabetes, hyperlipoproteinemia, low endogenous heparin, increased ureic acid and platelet adhesivity. Hypophysectomy by hypophysolysis (20 cases) brings relief and cures cardiovascular pathology, reduces AH, corrects the coronary risk factors, cures hypophyseal diabetes. The existence of AH and cardiovascular pathology is an indication for surgical treatment in evolutive acromegaly.

The diagnosis of primary dilated cardiomyopathy depends on the recognition of a dilated poorly contracting left ventricle with increased end-diastolic and end-systolic volumes in the absence of a detectable cause. The diagnosis is made only after exclusion both of structural heart disease and of known causes of secondary heart muscle disorder. The natural history is still largely unknown and is probably as variable as the likely causes. The left ventricular disorder does not cause symptoms until heart failure supervenes except for occasional patients who develop an early atrial or ventricular dysrhythmia, conduction defect, chest pain or murmur of mitral regurgitation. This period of latency may be short, prolonged or even permanent since it is unlikely that all cases progess to the point of failure. A few patients recover normal or near-normal cardiac function. The interplay between high blood pressure, hypertensive heart failure and dilated cardiomyopathy is illustrated by patients who recover from heart failure to become hypertensive and vice versa and in current treatment with vasodilators and diuretics for patients at either end of the spectrum.

Alongside reversible secondary pulmonary arterial hypertension accompanying neonatal respiratory distress, there are primary PAH leading to the persistence of the foetal circulation. This is a true functional neonatal heart disease which may occur alone or be seen in association with another form of neonatal distress such as respiratory distress secondary to the inhalation of amniotic fluid. Any neonatal hypoxaemia irreductible by classical methods should suggest the possibility of persistent pulmonary arteriolar vasoconstriction and lead, in the absence of systemic hypotension, to the administration of vasodilators. These data remain in the preliminary stage and further studies, in particular pharmacological, of these drugs are necessary.

A study of 200 pregnant women at the State Zenana Hospital, Jaipur, was conducted to analyse the effects of various maternal diseases on neonates. The maternal diseases were anemia, hypertension, urinary tract infection, heart disease, and tuberculosis. 200 healthy pregnant women were studied as controls. A high incidence (64.3%) of low birth weight babies were born to the unhealthy mothers. 80% of the tubercular mothered babies weighed less than 2.5 kg; 70% of the heart disease; 65% urinary tract infections; 60% hypertensive; and 64.3% anemia. The abnormal newborns showed a smaller average length and smaller head circumference (less than 33 cm.) than the normal group. There was also higher incidence of prematurity and poor neurological status among the abnormal group. Congenital malformations accounted for 2.15% in the abnormal cases, compared to .5% in the control group. The morbidity rate was 85%, compared to 46% in the controls. The causes were conjunctivitis, diarrhea, and cord sepsis.
