Effects Of Direct Mechanical Ventricular Actuation On The Apoptotic Signaling Of A Failing Heart, Scott Kerns

Cardiovascular disease accounts for more than 40% of all deaths in the United States (AHA-2004 report). A non blood contacting ventricular assist device (VAD) can be used to treat heart failure without the complications that arise from blood contacting VADs. This study used cellular markers of heart failure as indicators of heart function in an attempt to assess if direct mechanical ventricular actuation (DMVA) support lessened the impact of heart failure in rabbits. Cell signaling proteins were monitored using enzyme activity measurements and quantitative immunoblotting with antibodies against intrinsic and extrinsic apoptotic pathways during heart failure with and without DMVA …
