[Impairment of cognitive functions in patients with chronic thromboembolic pulmonary hypertension before and after surgical treatment].

Objective: To study cognitive functions in patients with chronic thromboembolic pulmonary hypertension (CTEPH) before and in the long-term after pulmonary thromboendarterectomy and to study factors that negatively affect cognitive status.

Material And Methods: One hundred and twenty-four patients with CTEPH were examined before and 6 months after surgery with an assessment of cognitive impairment using the Mini-Mental State Examination (MMSE). Multivariate regression analysis was used to identify factors affecting the MMSE indicators before and in the long-term postoperative periods.

[The role of integrated assessment of the indicators of external respiration function in cardiac surgical patients].

This literature review dedicated to the importance of an integrated assessment of external respiratory function in cardiovascular diseases (CVDs), including an analysis of up-to-date techniques, such as spirometry, body plethysmography, examination of the diffusing capacity of the lung, determination of O2 consumption with evaluation of the effectiveness of pulmonary ventilation. It considers the pathogenetic components of impairments in pulmonary ventilation and gas exchange, which develop in different CVDs, as well as during and after cardiac surgery. The authors analyze the results of international investigations and their own experience, which emphasize the prognostic value of lung function tests and suggest that there is a need for a comprehensive functional assessment of the respiratory system in cardiac surgical patients for their effective preoperative preparation, assessment and reduction of operational risks, and improvement of the prognosis of surgical treatment.

[Risk of Cerebral Complications of Surgical Treatment of Patients With Chronic Pulmonary Embolism].

Aim of the study was to assess risk of cerebral complications at the background of various methods of brain protection during surgery in patients with chronic pulmonary embolism (PE). We examined 61 patients aged 39-54 years operated because of chronic PE. Monitoring of cerebral oxygenation (rSO2, %) was performed at various stages of surgery.
