[The analysis of factors effecting professional self-assessment of physicians].

To explore the factors potentially related to professional self-assessment of physicians, sociological survey on the basis of sampling of 223 respondents who underwent professional training in 2017 was organized. The physicians with the first qualification category more often assessed themselves as "good" than other respondents (p=0.049). On the contrary, physicians with no qualification category rated their work as "good" less often and as "satisfactory" more often than other respondents (p=0.041 and p=0.010, respectively). The rate of professional self-assessment as "excellent" significantly increased among physicians identifying themselves with highest stratum of society (p=0.00034). Statistically significant differences in age, total duration of service in profession between physicians assessing their work for "excellent", "good" and "satisfactory" were not detected (p>0.05). The most frequent problems complicating life of physicians and their families were "Fatigue, overwork" (69.06%), "lack of free time" (60.09%), "low income" (44.39%). The reliable relationship between these factors and professional self-assessment was not detected (p>0.05). The relationship between professional self-assessment and availability of qualification category, as well as stratum of society to which they relate themselves, was established.

[Effect of ivabradine on pulmonary hypertension in chronic obstructive pulmonary disease].

In order to assess effect of If-channel blocker ivabradine on severity of pulmonary hypertension in chronic obstructive pulmonary disease (COPD) we studied 60 patients with III-IV stage COPD. We divided these patients into 2 groups with similar clinical characteristics and therapy. Patients of one of these groups received ivabradine (10 mg/day) for 2 weeks, patients of another served as controls. The use of ivabradine was associated with statistically significant lowering of pulmonary hypertension, heart rate, and increase of exercise tolerance without negative effects on myocardial contractility, electrophysiological parameters, or data of spirometry.
