ABSTRACT
UNLABELLED: The aim of the study---a comprehensive assessment of haemodynamic alterations during pneumonectomy using pulmonary arterial volumeter (PAV) opportunities. MATERIALS AND METHODS: 72 patients were included in the study, (the average age - 51 +/- 3,8 years, body weight - 68 +/- 7 kg), who underwent pneumonectomy about lung tumors under general anesthesia with separate ventilation (on indications - jet high-frequency ventilaton).

Latent dysfunction of the heart right ventricle and hypovolemia were assessed in 50 patients divided into 4 groups, operated on the heart, abdominal aorta and lungs. It was found that after revascularization of the myocardium the diastolic disorders prevailed. In patients operated for the heart valve (mitral and aortal) diseases prevailing were the systolic and pump dysfunction of the right ventricle. Insufficiency of the right ventricle in these groups was 13% and 22% respectively. After operations on the abdominal aorta a combination of the systolic and diastolic impairments of the right ventricle were observed. After extended resections of the lungs there was a characteristic combination of systolic, diastolic and pump dysfunctions. When the operation was followed by a decreased minute volume of circulation, its cause was hypovolemia in 29% of cases in the examined surgical patients. The investigation of the right ventricle functions with the help of pulmonary arterial volumetry can reveal their latent dysfunctions as well as hypovolemia in a considerable part of surgical patients.

One of the main difficulties in cardiology is how to correctly choose the volume and method of treatment in elderly patients with ischemic heart disease. 165 elderly patients with IHD were included into the study. 83 patients received partial myocardial revascularization by PTCA and stenting and 82 patients were on the conservative medical treatment. The state of coronary flow was estimated by means of the Holter-monitoring and treadmill-test results. Contraction ability of the heart was evaluated by echocardiography. The Quality of life level in patients was measured by SF-36 questionnaire. The results prove that elderly patients with IHD can benefit from the early partial myocardial revascularization which increases coronary circulation, quality of life level and preserves left ventricular function.
