Question

How are preload, afterload, and contractility managed therapeutically in the patient with heart failure?

Expert Solution

Step 1

Heart failure is characterized by the heart’s inability to pump an adequate supply of blood to the body.
Without sufficient blood flow, all major metabolic body functions are disrupted.
Heart failure is a collection of symptoms that weaken your heart.
In some people with heart failure, the heart has difficulty in pumping enough blood to support other organs in the body.
Heart failure can affect the right or left side of your heart or both at the same time.
It can be either an acute or chronic condition.
