[Disordered diastolic function of the left ventricle in patients with coronary heart disease depending on ejection fraction].

The authors present data on the occurrence of different types of left ventricular diastolic function in patients with coronary heart disease collected in the course of population-based epidemiological study. The diastolic function was evaluated from parameters of transmitral blood flow depending on ejection fraction.

[Changes in myocardial hemodynamics and contractile function in patients under surgical treatment for prostatic adenoma]. / Izmeneniia gemodinamiki i sokratitel'noi funktsii miokarda u bol'nykh pri operativnom lechenii adenomy predstatitel'noi zhelezy.

Hemodynamics and left ventricular myocardial contractility in 170 patients who underwent surgery of prostatic adenoma were examined in preoperative period and 16 days after single-stage transvesical adenomectomy. The age of the patients varied from 52 to 85 years. Echocardiography and the dilution method were used for the evaluation. The increase of end-diastolic and end-systolic volumes, stroke volume, cardiac index, was registered. The combined pharmacological treatment made it possible to decrease the number of operative and postoperative cardiovascular complications.

[Disorders of pulmonary hemodynamics in patients with diabetic nephroangiopathy and its correction with antioxidants]. / Narusheniia legochnoi gemodinamiki u bol'nykh s diabeticheskoi nefroangiopatiei i ikh antioksidantnaia korrektsiia.

Hemodynamic changes of lesser circulation were investigated in 108 patients with diabetic nephroangiopathy. They were also given vitamin E therapy (8 micrograms/kg of body mass) for 2 weeks to correct metabolic derangements and indices of pulmonary hemodynamics. Partial renal function was determined with 131I-hippuran and 99mTc-DTPA renoscintigraphy. Pulmonary hemodynamics was assessed with pulmonary scintigraphy (MAA 99mTc). The results have shown that vascular renal lesions in diabetes mellitus cause hypertension of lesser circulation and disorders in pulmonary microcirculation, and disorders of lipid metabolism and activation of lipid peroxidation (LPO) progress with augmentation of severity of disease. Vitamin E therapy improves pulmonary hemodynamics, lipid metabolism and LPO. Antioxidant correction was most effective at the initial stages of diabetic nephroangiopathy.

[Standard indicators of pneumotachometry and the Votchal-Tiffeneau index in the evaluation of external respiratory function in adolescents]. / Normativnye pokazateli pnevmotakhometrii i indeksa Votchala-Tiffo v otsenke funktsii vneshnego dykhaniia u podrostkov.

A study was made of the indices of pneumotachometry (PT): PT of exhalation, PT of inhalation and their ratio--in 263 adolescents (125 boys and 138 girls) with normal physical and sexual development. Direct correlation of sex, age and height with PT indices was established. Linear regression equations were made up for the calculation of standard parameters. It was shown that the ratio of PT of exhalation/PT of inhalation less than I in clinically healthy adolescents could not be a sign of disorder of bronchial permeability. The spirographic Votchal Tiffeneau index was-studied in 260 of them (125 boys and 135 girls). The lower permissible normal limit for the Metatest-1 spirograph was 76.5 +/- 0.4%.
