Диастолическая трансторакальная стресс-эхокардиография с дозированной физической нагрузкой в диагностике сердечной недостаточности с сохраненной фракцией выброса: показания, методология, интерпретация результатов

Диагностика сердечной недостаточности с сохраненной фракцией выброса сопряжена с определенными трудностями, поскольку многие пациенты с сердечной недостаточностью с сохраненной фракцией выброса имеют незначительную диастолическую дисфункцию левого желудочка и нормальное давление его наполнения в покое. Для улучшения диагностики сердечной недостаточности с сохраненной фракцией выброса используется диастолическая трансторакальная стресс-эхокардио графия с дозированной физической нагрузкой (диастолический стресс-тест), позволяющая выявить признаки повышения давления наполнения во время нагрузки. В настоящем согласованном мнении экспертов разъясняется необходимость проведения диастолического стресстеста для диагностики сердечной недостаточности с сохраненной фракцией выбро са с клинической и патофизиологической точек зрения, определяются показания к тесту с описанием его методологических аспектов, рассматриваются вопросы применения теста у особых категорий пациентов.
