[Origin of the left coronary artery from the trunk of the pulmonary artery. Report of a case].

The congenital anomalies of the coronary arteries are varied. The left trunk arising from the pulmonary artery is a rare and serious one. With coronary angiography the diagnosis is possible. The surgical technics offer an effective treatment. We report the first case with these anomalies at the Instituto Nacional de Cardiología Ignacio Chávez. It was diagnosed with coronary angiography and it was treated by suturing the left main coronary artery in its origin, and with implantation of a safenous vein graft between the aorta and the left main coronary artery. The results were satisfactory.

[Clinical impact of the Bezold-Jarisch reflex in coronary arteriography].

To evaluate the role that coronary arteriography has in the induction of the Bezold-Jarisch reflex we study 9 patients (group I) to whom 1 mg. of atropine was administered 45 min. before the coronary arteriography and 9 patients (group II) without pre-medication. The heart rate was measured before, during and after each intracoronary injection. In group I there was no change in heart rate in 6 patients, in 3 cases the heart rate dropped to 15 beats/min. In group II the heart rate decreased in 8 cases. We conclude that the injection of radiologic contrast material in the coronary arteries triggers the Bezold-Jarisch reflex and that this reflex is prevented by the administration of atropine.

[Myocardial reinfarction in male and female].

1). In 1001 patients with acute myocardial infarction 403 cases were found (40.2%) showing possible relapse. A study was made of 125 cases (12.5%) with positive diagnosis of acute myocardial infarction relapse, and among them, 12 were found to be occurring for the third time. Is possible for the real frequency of the iterative infarction to be even higher, because many cases were dismissed (27.7%) for lacking of conclusive electrocardiographic data pointing to myocardial transmural infarction. 2). Investigations were conducted about the evolutive condition of the danger factors in the coronary profile as well in the male as in the female group. Besides, a comparative study was made about symptoms, complications, morbidity and mortality. Clinical, enzimatic and electrocardiographic proofs were found, in every case, of a new myocardial transmural necrosis which was in evolution, with waves of injury and ischemia. Thirty eight deaths were registered in hospitals (30.4%) and in 25 of these, a necropsic study was conducted. 3). This illness is more frequent among men than among women, in a 3.5 to 1 proportion. The recurrent myocardial necrosis tends to be more frequently present during the first year following the first episode. In women, the first myocardial infarction as well as the iterative infarction occur at an older age than in men. 4). The influence of personality and stress is a very important factor of danger in the iterative infarction. Familiar antecedents of ischemic cardiopathy constitute a danger factor in patients presenting a single episode of myocardial infarction; nevertheless they don't seem to have a determining influence in this group of relapsing infarction. Although this study confirms with statistics that smoking has a decisive influence in the first myocardial infarction, neither frequency nor mortality of the relapsing infarction are in any way modified by the diminishing or suppression of the smoking habit.

[Chorea and chloroquine. A new treatment for an ancient malady].

Chloroquine is a drug used mainly as an anti-malaria agent with many other pharmacological properties. It was given to a patient with chorea and disseminated lupus erytematosus seeking the anti-inflammatory effect of the drug. The unexpected result on chorea hastened its use in 7 other patients with the same success. Chloroquine seems to be an effective drug for the relief of chorea. The mechanism of action is unknown.

[Coronary arteriovenous fistula].

We present the case of an 8 year old boy with A-V fistula from the right coronary artery to the right ventricle, successfully treated by surgery. The main clinical features with differential diagnosis are discussed and the advantages of early surgical treatment are commented.

[Cardiac neurosis. Study of 100 cases with a healthy heart].

One-hundred records taken at chance from the archives of the Instituto Nacional de Cardiología de México, with the diagnosis of healthy heart, were studied. The following factors of these patients were analyzed: age, sex, civil status, socio-economic level, occupation, family antecedents, personal antecedents, smoking, alcoholism, presence of cardiac murmurs, arrhythmias, and electrocardiogram. In 80 of these patients there existed a clear neurotic alteration. The main symptoms which they suffered were: dyspnea, pain, palpitations, dizziness, and headaches. We found that the influence of the medical environment and living with cardiac patients in a neurotic individual were predisposing factors of a cardiac neurosis. In many cases the physician is responsable if he hesitates or does not advice properly. It can be concluded that it is necessary to establish a rehabilitation program for these patients since the illness is serious and invalidating and very frecuent, with repercussions at the familiar, social, and economic levels.
