True or false:
Wall stress is inversely related to EF
Definition
True
Wall stress is a marker of afterload and ejection fraction is inversely related to afterload
Term

What is the effect of concentric hypertrophy on wall stress?
Definition
Concentric hypertrophy lowers wall stress. stress=Pressureā€¢Radius/wall thickness
Term
AS
What is stress?
Definition
Force per unit area at a given dimension
