ПРОГНОСТИЧЕСКАЯ ЗНАЧИМОСТЬ ЭХОКАРДИОГРАФИИ ПОСЛЕ ОСТРОГО ИНФАРКТА МИОКАРДА. ЧАСТЬ 2

Эхокардиография является полезной методикой для стратификации риска и оценки прогноза после острого инфаркта миокарда. Показано, что для получения прогностической информации можно использовать множество традиционных эхокардиографических параметров, таких как объёмы и фракция выброса левого желудочка, индекс движения стенки, объём левого предсердия и наличие митральной регургитации. Разработка методов тканевой допплерографии и “speckle-tracking” привела к появлению новых прогностических параметров, таких как деформация, скорость деформации и диссинхрония левого желудочка. Методика контрастной эхокардиографии позволяет оценивать перфузию миокарда и целостность микрососудистого кровоснабжения, предоставляет ценную информацию о жизнеспособности миокарда, тесно связанной с прогнозом. Стресс-эхокардиография позволяет выявить ишемию и жизнеспособный миокард, допплерография коронарных артерий — оценить резерв коронарного кровотока, и, наконец, трёхмерная эхокардиография даёт оптимальную информацию об объёмах, функции и сферичности левого желудочка, которые также являются важными параметрами долгосрочного прогноза.
