Данная статья посвящена оценке показателей миокардиальной работы левого желудочка (ЛЖ) с помощью методики построения кривых давление–деформация – новому инструменту в эхокардиографии, способному учесть влияние постнагрузки сердца на сократительную способность ЛЖ. Подробно изложены алгоритм действий по оценке миокардиальной работы, возможные трудности и особенности расчета ее основных показателей, обсуждены ограничения и недостатки методики. В статье приведены нормальные значения показателей миокардиальной работы ЛЖ, представлены их характерные изменения и преимущества использования при различных заболеваниях и патологических состояниях сердца.

This article is dedicated to the assessment of left ventricular (LV) myocardial work indicators using the method of constructing pressure-strain loops, a new tool in echocardiography that can take into account the influence of cardiac afterload on LV contractility. The algorithm of actions for estimating myocardial work, possible difficulties and features of calculating its main indicators are described in detail, the limitations and disadvantages of the method are discussed. The normal ranges of LV myocardial work indicators are given in the article, and it presents their typical changes and the advantages of using in various diseases and pathological conditions of the heart.
