Right Ventricle Functional State in Patients with Coronary Artery Disease
Abstract
Aim of the study was to assess right ventricle function in patients with coronary artery disease in cases with normal and abnormal left ventricle myocardium contractility. 95 patients with verified coronary artery disease aged from 28 up to 79 years old were included into the study. First group consisted of patients without left ventricle myocardium local contractility dysfunction (n = 35), second group - patients with dysfunction of left ventricle myocardium local contractility of the anterior, septal, posterior, and lateral localization (n = 60). Value of tissue Doppler imaging and speckle tracking in patients with right ventricle dysfunction in cases of left ventricle local contractility dysfunction was assessed. Study results showed that longitudinal strain of right ventricle significantly changes only in patients with left ventricle local contractility dysfunction. Decrease of the right ventricle longitudinal strain, acceleration time before the peak of longitudinal strain, and peak of post-systolic shortening occurrence indicate at right ventricle dysfunction. The value of right ventricle lateral wall longitudinal strain assessed by speckle tracking is the most optimal parameter for diagnosis of right ventricle dysfunction in patients with left ventricle local contractility dysfunction.
