Distinctive Features of Systolic Function of the Left Ventricle in Patients with Chronic Obstructive Lung Disease in Extremely Cold Climate Conditions

摘要

The purpose of this study was to identify the characteristics of systolic dysfunction and the formation of chronicpulmonary heart disease in patients with COPD living in the central zone of the Republic of Sakha (Yakutia). This articledescribes the echocardiographic indices of systolic dysfunction of the heart in 229 patients with chronic obstructivepulmonary disease of the Republic of Sakha (Yakutia). According to our data, severe decompensation of chronic pulmonaryheart disease with symptoms of heart failure of right ventricular type in most cases combined with severe leftventricle systolic dysfunction, not related to the primary pathology of the left heart and leading to a further decline in thequality of life of patients and increase in the risk of fatal diseases.
