Hög frekvens Doppler ultraljud är en ny teknik för att bedöma regionala hjärtinfarkt funktion. Detta arbete presenteras först uppgifter som styrker tillämpningen av denna mångsidiga imaging plattform för upprepade mått av hjärtinfarkt stam, dp / dt, och mitralis-insufficiens i ischemi-reperfused (IR) murina hjärtat.
