title: [Geometric state of the heart left ventricle and its correlation with contraction processes in patients with chronic obstructive bronchitis].
abstract: Geometrical features of contraction of the left ventricle of the heart (LVH) in 41 patients with chronic obstructive bronchitis marked by moderate and severe respiratory disorders without clinical signs of heart insufficiency with the help of a morphobiomechanical have been examined. The patients were selected in subgroups with different ejection fraction of LVH. The patients with diminished ejection fraction were found to have signs which respond to left ventricle dysfunctions of the heart. They are the following: loss of ability of the heart to form normal elliptical configuration during systolic contraction, extension of longitudinal contraction, and decrease in relative wall thickness of the left ventricle of the heart. It may be considered as an early sign of damage of the heart followed by development of chronic heart insufficiency.
