Concerning the adaptation to cardiac valvular dysfunction, the following is/are true:
A.	Severe heart failure is more likely from acute than chronic valvular dysfunction
B.	Valvular dysfunction produces both volume and pressure afterload stress on the heart
C.	Early cardiac dilation from valve dysfunction shifts the Frank-Starling curve to depress cardiac output
D.	The LaPlace law predicts that wall stress decreases with increasing ventricular radius
