[Myocardial biomechanics in patients with coronary circulatory insufficiency].
The paper analyzes a new approach to evaluating myocardial systolic and diastolic function, which is based on recording of the rate of myocardial displacement in different phases of a cardiac cycle. Changes in the rate of vector movements in a period of isovolumic contraction and relaxation are shown on ample clinical materials in both healthy individuals and patients with coronary heart disease. There is evidence for a significant difference in the performance of a stress test by healthy individuals and patients with a low coronary circulatory reserve.
