Types Of Heart Failure
Systolic dysfunction
When the heart muscle doesn't contract with enough force, there is less oxygen-rich blood that is pumped throughout the body
Diastolic dysfunction
The heart contracts normally, but the ventricle -- the main pumping chamber -- does not relax properly, reducing the amount of blood that can enter the heart and raising blood pressure in the lungs.
