Q

What is congestive heart failure?

A

Occurs when the heart muscle does not pump blood as well as it should

Conditions such as coronary artery disease or high blood pressure leave the heart too weak or stiff to fill and pump efficiently

Q

What are the effects exercise training has on chronic heart failure?

A

Improved skeletal muscle metabolism,
improved endothelial function,
increased vasodilatory capacity and redistribution of cardiac output
Physical functioning, quality of life and morbidity/mortality

Q

What is atherosclerosis?

A

Chronic inflammatory process
Plaque build-up and hardening inside arteries
Limits flow of oxygen-rich blood to organs and other parts of the body

17
Q

What is peripheral artery disease?

A

Common circulatory problems in which narrowed arteries reduce blood flow to limbs

Causes leg pain while walking
