The clinical, electrocardiographic, angiographic, and hemodynamic features of seven patients with isolated, severe (greater than 75% of diameter) narrowing of a diagonal branch of the left anterior descending artery are presented. The incidence of this entity was 0.5% among patients with arteriosclerotic heart disease undergoing coronary angiography. Angina was severe in two patients, moderate in four, and mild in one. One patient had unstable angina. Stress tests were abnormal in two of three patients. Six patients had normal left ventricular angiograms, and one had a mildly decreased ejection fraction. All patients survived a mean follow-up of 18 months (range 6 to 32). No patient suffered a myocardial infarction. Five became asymptomatic on medical therapy; one patient with mild and another with moderate angina were unimproved. This rare anatomic subset of patients with coronary artery disease has a favorable short-term prognosis.

Intending to find out which is the prevalence of mitral valvular prolapse in cases of ischemic cardiopathy with "normal" coronariography, a review was made of the coronary-ventriculographic studies at the I.N.C. archives, which showed as clinical diagnosis that of ischemic cardiopathy with "normal" coronaries. In the present studies we record 47 cases showing chest angina and/or electrocardiographic changes in rest or effort tests, compatible with myocardic ischemia and coronariography undoubtedly normal. We found 30 cases (63.8%) showing strong evidence of mitral prolapse in the left cineventriculography taken in right-front oblique position.

Training with resistant exercises has been proved to be beneficial for patients of ischemic cardiopathy. This kind of training increases working capacity, provided the exercise is maintained in the necessary threshold to avoid starting a chest angina. Nevertheless, there is no clear evidence of an increase in the blood flooding of the myocardio, the left ventricle function or the heart electric stability as a consequence of the said training. It's our opinion that the principal reasons for this lack of evidence are: a) insufficient research, b) the existence of technical difficulties for developing certain phases of the necessary research, and maybe that, c) some exercise programs are not sufficiently long and intense and to induce myocardial adaptation. The purpose of this study is to determine if a long program of physical exercise training could produce a better blood irrigation and ventricular function as well as restore the electric stability. This approach to the problem is justified by the recent finding of adequate methods which really and definitely answer these questions with the results obtained through properly controlled physical exercise.

Of 18,000 children with organic heart disease evaluated at The Hospital for Sick Children, Toronto between 1940 and 1971, 33 died suddenly and unexpectedly between 1 and 21 years of age. Nine had discrete obstruction of the left ventricular outflow tract and five had muscular narrowing of the left ventricular outflow tract and five had muscular narrowing of the left ventricular outflow tract. Pulmonary vascular disease caused seven sudden deaths, and arrhythmias (usually due to atrioventricular block) caused seven more. Of the five other children who died suddenly three had transposition of the great arteries, one had a complex cyanotic heart defect and one had an anomalous course of the left coronary artery, which originated from the right sinus of Valsalva. With earlier investigation of aortic stenosis, earlier closure of ventricular septal defect to avoid pulmonary vascular disease, better design of artificial pacemakers and better investigation of patients with angina, many of these deaths will be avoided in the future.

Action taken by the Food and Drug Administration (FDA) toward the th erapeutic use of estrogens is reported. The FDA has 1st ordered revision of physician-labeling for estrogens, and 2nd has prepared a brochure explaining the advantages and disadvantages of estrogen therapy to patients. Some of the points made in the new labeling and brochure are: 1) the risk of cancer of the uterus increases with duration of use and dosage; 2) users of estrogens should be examined by their physicians at least every 6 months; 3) estrogens should never be given to pregnant women; 4) estrogens should not be given in cases of breast or uterine cancer, undiagnosed abnormal vaginal bleeding, clotting in the legs and lungs, or previous heart disease, angina, or stroke; and 5) estrogens should not be used to treat menopausal nervousness, as they have proved ineffective, or for improving the complexion. There is also no evidence that estrogens are effective in preventing threatened or habitual abortion. It is recommended that estrogens be administered cyclically (3 of 4 weeks), and that the dosage be reduced or discontinued every 3-6 months to assess the need for their continued use.

Cardiac catheterization was used to evaluate 298 asymptomatic, apparently healthy aircrewmen with electrocardiographic abnormalities. These men were identified from annual electrocardiograms and exercise tests used to screen for latent heart disease. Data from 27 additional symptomatic aircrewmen who underwent cardiac catheterization because of mild probable angina pectoris are also included. The men were grouped according to major reason for cardiac catheterization. The order of groups by increasing prevalence of coronary artery disease was as follows: abnormal treadmill test (labile lead only), supraventricular tachycardia, right bundle branch block, left bundle branch block, abnormal treadmill test, ventricular irritability, probable infarct and angina. Approximately 60 percent of the men were completely free of angiographic coronary artery disease. Risk factors and other possible causes for the electrocardiographic abnormalities are discussed. The electrocardiographic abnormalities studied have a poorer predictive value for coronary artery disease in asymptomatic apparently healthy men than in a hospital or clinic population.

The early diagnosis of heart disease during or better before pregnancy is one of the most important problems, as cardiac diseases are the most common cause for maternal deaths throughout the world. The knowledge of hemodynamic alterations in circulatory and respiratory physiology during pregnancy complicated by heart disease is a prerequisite for their management. The following indications for therapeutic abortion of pregnancy complicated by heart disease can be concluded according to our own observations: 1. history of significant heart failure (more than grade IV according to the classification of the New York Heart Association), frequent attacks of angina pectoris and longstanding cyanosis: 2. in spite of the most careful heart treatment with digitalis, diuretics and salftree diet cardiac-thorax-rate of more than 55% in congenital heart disease, cardiac-thorax-rate of more than 60% in acquired heart disease, significant signs of heart failure, namely more severe than grade III, tachycardic atrial fibrillation, pulse deficit of more than 30/min, active inflammatory processes of the heart (rheumatic fever, subacute bacterial endocarditis, Takayasu's disease); 3. especially severe metabolic disorders, i.e. diabetes mellitus, malignant hypertension, kidney diseases; 4. primiparae of an age of more than 35 years with any heart disease. Commissurotomy can be accomplished during pregnancy if it is too late for therapeutic abortion. Pregnancy in case of artificial valves is not recommended in general because of impending hemorrhagic diathesis.

A case of Prinzmetal angina refractory to classic medical treatment, in which the angina attacks were suppressed with the administration qf reserpine is presented. The possible physiopathologic mecanisms of this entity are reviewed. The possibility of coronary spasm due to an alteration in the regulation of the coronary arterial tone from an autonomic.nervous system illness is established, an abnormal coronary vascular reactivity is also reviewed. It is emphasized that the Prinzmetal angina is an original entity, idfferent from the coronary arteriosclerotic heart disease, which may coexist with it but which cannot be treated in the same way, because its physiopathologic mecanisms are different.

Studies were made for evidence of heart disease on 501 people aged 65 and more living at home; 22-4 per cent had clinical and/or electrocardiographic evidence of ischaemic heart disease. The prevalence of ischaemic heart disease increased with age, and was slightly greater in men than women. The frequency of ischaemic heart disease increased with increasing current cigarette consumption and with total cigarette consumption. There was no increase in relation to any of the following possible risk factors: systolic and diastolic blood pressure, blood glucose, serum cholesterol, skinfold thickness, percentage of ideal body weight. The survival over a 5-year period of all subjects with ischaemic heart disease did not differ significantly from that of all subjects together, but the mortality of subjects with ischaemic heart disease and an abnormal electrocardiogram was 1-5 to 2 times that of subjects in whom ischaemic heart disease was diagnosed on the basis of angina pectoris or past cardiac infarction, the electrocardiogram being normal.

In 134 patients with coronary artery disease, long-term oral anticoagulant therapy (mean duration, 56 months) for acute myocardial infarction (98 patients), acute coronary insufficiency (25 patients) or severe chronic angina (11 patients) was terminated abruptly in 50 patients (group 1) and gradually in 84 (group 2). The 134 patients represented a homogeneous population of patients with coronary artery disease since most patients older than 75 years and those with conditions known to increase the risks of thromboembolic complications were excluded. The two groups were comparable in terms of sex, age, presence of risk factors, duration of anticoagulant therapy, and presence of angina and abnormal resting electrocardiograms during therapy. Patients were evaluated 6 months after cessation of anticoagulant therapy and, since abrupt withdrawal of therapy did not carry a higher risk than gradual discontinuation, data for groups 1 and 2 were tabulated together.Of the 84 patients with angina at the end of therapy 15 experienced an increase in its severity and this symptom appeared in another patient (relapse rate, 18%). Angina progressed to fatal acute myocardial infarction in four (mortality, 3%) and nonfatal infarction in two; however, all six had extensive coronary artery disease and poor left ventricular function. The results of this study suggest that neither abrupt nor gradual cessation of anticoagulant therapy is associated with an inordinate exacerbation of heart disease.
