Диастолическая трансторакальная стресс-эхокардиография с дозированной физической нагрузкой в диагностике сердечной недостаточности с сохраненной фракцией выброса: показания, методология, интерпретация результатов Согласованное мнение экспертов, выработанное под эгидой ФГБУ «Национальный медицинский исследовательский центр кардиологии» МЗ РФ, Общества специалистов по сердечной недостаточности (ОССН) и Российской ассоциации специалистов ультразвуковой диагностики в медицине (РАСУДМ)
Диагностика сердечной недостаточности с сохраненной фракцией выброса (СНсФВ) сопряжена с определенными трудностями, поскольку многие пациенты с СНсФВ имеют незначительную диастолическую дисфункцию левого желудочка и нормальное давление его наполнения в покое. Для улучшения диагностики СНсФВ используется диастолическая трансторакальная стресс-эхокардиография с дозированной физической нагрузкой (или диастолический стресс-тест), позволяющая выявить признаки повышения давления наполнения во время нагрузки. В настоящем согласованном мнении экспертов разъясняется необходимость проведения диастолического стресс-теста для диагностики СНсФВ с клинической и патофизиологической точек зрения; определяются показания к тесту с описанием его методологических аспектов; рассматриваются вопросы применения теста у особых категорий пациентов.
