Causes And Potential Treatment For Altered Muscle Metaboreflex Control Of Ventricular Vascular Interactions In Heart Failure, Joseph Thomas Mannozzi
Wayne State University Dissertations
Muscle Metaboreflex Activation occurs as a result of metabolic accumulation within active skeletal muscle that stimulates type III and IV afferents. This reflex in healthy subjects causes increased ventricular contraction, tachycardia, enhanced central blood volume mobilization, and 2 mediated vasodilation as a means to increase mean arterial pressure and thereby improve perfusion pressure of active skeletal muscle. However, to date no study has evaluated the interaction between the observed changes in ventricular and vascular dynamics or how the reflex impacts contraction relaxation dynamics before and after induction of heart failure Furthermore, no study has evaluated the impact of chronic selective …
