Why does left heart failure produce decreased contractility and increased preload and afterload? |
[Edit] |
[Edit] 
When a person has hypertension, the ventricles will hypertrophy, which makes the chambers larger. Afterload is directly related to the chamber size, and contraction velocity is inversely related to afterload. Contraction velocity is a measure of contractility. So, as chambers hypertrophy, contactility decreases.

What is preload? Meaning of preload? What is the preload? What do you mean by preload in heart? Is cardiac output affected by preload or afterload? If Preload is increased how does it effect contractility?
