ABSTRACT

To examine feasibility of usage of phase IV hemodynamic alterations in the course of Valsalva's test in patients with bronchial asthma for detection of latent insufficiency of the right heart and pulmonary hypertension, 24 patients with mild bronchial asthma and 8 healthy individuals were subjected to Doppler echocardiography. The results indicate that this method is simple, well tolerated, can assess functional reserves of the lesser circulation. It can be used both for primary diagnosis and follow-up.

ABSTRACT

In 43 patients suffering from bronchial asthma, the data on patients with normal and high systemic arterial pressure were correlated on the basis of studying external respiratory function and pulmonary circulation. The differences are demonstrated as regards the intensity of obstruction, the ratio of changes in lung perfusion to bronchial patency, the response to berotec and the calcium antagonist perdipine.

ABSTRACT

A method introduced by the authors for the diagnosis of chronic cor pulmonale based on the evaluation of Sokolov's and Lion's electrocardiographic criteria is described. The results presented were checked by comparing the pathoanatomic data of 124 patients dying of chronic pulmonary lesions, as well as the analysis data of ECG recorded in 92 normal individuals with a vertical or semi-vertical electric position of the heart. The advantages of the suggested method over that of Widimski are indicated.

ABSTRACT

In calculating the cardiac output on the basis of the dye dilution curves it is important to determine the area of the first circulation of the dye. The existing techniques of the determination of this area are different in their complexity and precision of the obtained results. A comparative evaluation of 14 techniques or their modifications for the determination of the cardiac output according to the Evans blue dilution curves was undertaken in 40 subjects (normal individuals and patients with chronic pulmonary pathology). A new method of calculations of the area by two triangles is suggested. The most precise techniques appeared to be the planimetric method of exponential extrapolation, the two and five triangles methods introduced by the authors, as well as the calculations of Hamilton and Simpson. It seems most rational to use the two and five triangles methods that are not only precise, but also simple. The method with five rectangular triangles should be preferred since it does not require any special equipment. In exceptional cases, in which the recirculation wave begins early and/or the direction of the descending portion is not clear, the Dow equation may be recommended, with the results multiplied by the factor of 1.26.
