About
Advanced heart failure (when the heart pump fails) is associated with symptoms such as shortness of breath and extreme fatigue. Some of these symptoms are simply due to failure of the pump, however abnormal regulation of blood flow to the muscles of the body is also a potential mechanism. Left ventricular assist devices are mechanical pumps used to compensate for patients with failing hearts either as a bridge to heart transplant or as long term therapy. Whether or not these pumps improve muscle flow and whether this is a determinant in the improvement of symptoms is unknown. Understanding how skeletal muscle and heart perfusion is altered in heart failure patients before and after implantation of an LVAD could provide further insight into the beneficial effects of this therapy.

Full description
Methods:
Thirty patients deemed to be candidates for LVAD from either outpatient heart failure clinic or inpatient cardiology service will be studies. Skeletal muscle perfusion imaging using standard of care ultrasound technology will be performed prior to LVAD implant and then 3 months post implant. Functional status by six minute walk test and specialized stress test will be assessed at 3 months post implant.
