Цель: разработать новый модифицированный индекс для оценки биоэнергетики сокращения сердца в условиях сердечной недостаточности при механической поддержке кровообращения. Провести оценку биоэнергетики сердца при использовании систем обхода левого желудочка сердца с использованием насосов непульсирующего потока. Рассмотреть принципиальное преимущество насосов непульсирующего потока с генерацией пульсирующего потока в режиме кардиосинхронизированной сопульсации перед режимом контрпульсации.

Aim: to develop a new modified index for the assessment of bioenergy heart in conditions of heart failure. To assess the energy of the heart when using systems to bypass the left ventricle of the heart using non-pulsed flow pumps. To consider the fundamental advantage of non-pulsating flow pumps with the generation of a pulsating flow in the cardio-synchronized copulsation mode over the counterpulsation mode.
