摘要:
We provide herein a method of preventing or limiting the effects of heart failure in a human patient that has sustained myocardial infarction by reducing maladaptive cardiac remodeling in the patient. The method comprises percutaneously inserting a transvalvular blood pump, comprising a rotor and a cannula, into the patient's vasculature and positioning the cannula across the aortic valve of the patient's heart, with a distal end of the cannula located in the left ventricle of the heart and a proximal end of the pump located in the aorta. The method then comprises, prior to reperfusing the heart, operating the positioned pump to unload the left ventricle at a pumping rate of at least 2.5 L/min of blood flow for a support period between at least 30 minutes and less than 60 minutes. Then, after the support period, the method comprises applying coronary reperfusion therapy to the heart.
