Эхокардиография в оценке постсистолического укорочения миокарда левого желудочка сердца
Эхокардиография позволяет оценивать сократимость миокарда левого желудочка (ЛЖ), однако визуальная оценка сократимости является субъективной и требует большого опыта. Современные технологии оценки сократимости миокарда ЛЖ, такие как тканевая допплерография и спекл-трекинг эхокардиография, позволяют количественно оценивать различные параметры деформации миокарда, в том числе постсистолическое укорочение миокарда ЛЖ. В нескольких исследованиях продемонстрированы возможности постсистолического укорочения в оценке ишемии миокарда и «ишемической памяти» миокарда у пациентов с сердечно-сосудистыми заболеваниями. В данном обзоре представлен анализ экспериментальных и клинических исследований, изучавших постсистолическое укорочение миокарда ЛЖ.
