[Myocardial contraction in ischemic heart disease].

The indices of contractility of the left ventricular myocardium were studied by means of ventriculography and catheterization in 84 patients with ischemic heart disease according to the extent of damage to the coronary arteries and the course of the disease. Changes in the coronary arteries were encountered twice as frequently among patients with postinfarction cardiosclerosis as among patients with angina pectoris and no history of infarction. The main cause of disorders of myocardial contractility in patients with ischemic heart disease is post-infarction cardiosclerosis (56% of cases). Signs of impaired functional capacity of the left ventricle appeared in segmental asynergy involving 20 to 25% of its circumference. Changes in the indices of contractility were revealed in 13% of patients with angina pectoris.

[Evaluation of the hypotensive effect and indications for the operation of nephropexy in patients with arterial hypertension combined with nephroptosis].

The results of the examination and nephropexy operation in 11 patients with arterial hypertension and nephroptosis are presented; a hypotensive effect was achieved in 5 of the operated patients; the follow-up period was up to 3 years. The recordings included the elevation of the arterial pressure in orthostasis, the changes in the urine sediment, the activity of plasma renin at rest and after 1-hour's orthostasis; excretory urography and the Seldinger abdominal aortography in a lying and upright position of the patient were conducted, as well as intraoperative biopsy of the renal tissue. Patients with a hypotensive effect exhibited a regular elevation of the arterial pressure in orthostasis, an increased plasma renin activity, congestive features in the descended kidney. The above symptoms permit to distinguish groups of patients with a hypotensive effect achieved after nephropexy, and those without effect. On the basis of the obtained results it was concluded that in some cases nephroptosis may be the cause of symptomatic arterial hypertension. In such cases it seems rational to recommend the nephropexy operation taking into account, when determining the indications for surgery, the degree of the orthostatic elevation of the arterial pressure and of the renin activity, and the symptoms of disorders in the renal evacuation function.

Problems of the pathogenesis, clinics, and therapy of panarteritis of the aorta and its branches.

138 patients with panarteritis of the aorta and its branches were examined, and the clinical and morphological findings were compared. The disease is more widespread than has been assumed so far, and is more frequent in young women. Localization of the process in the abdominal aorta with involvement (stenosis) of renal arteries causes renovascular hypertension, which often has a malignant course, especially with an ambilateral affection of renal arteries. In the treatment, repetitive therapeutic courses with corticosteroids and heparin are of fundamental importance. With an isolated affection, especially in renovascular hypertension and disturbances of cerebral circulation, surgical treatment is also indicated.

[Cordaron and nonachlasine in treatment of chronic coronary insufficiency].

In a double blind study of the clinical effect of Cordaron conducted in 55 patients with chronic ischaemic heart disease a positive effect was obtained in 80.4% of the cases, an effect of placebo-in 24.3%. Cordaron was especially effective in patients with localized stenoses of the coronary arteries. Nonachlasine (an activator of the cardiac beta-adrenergic receptors) proved effective in 10 of 13 patients with chronic ischaemic heart disease.
