Cardiogenic shock is a disease state where the heart is damaged enough that it is unable to supply sufficient blood to the body.

Heart failure, also called congestive heart failure, is a disorder in which the heart loses its ability to pump blood efficiently. The term "heart failure" should not be confused with cardiac arrest, a situation in which the heart actually stops beating.
|

|
Heart failure can happen in two ways. The heart muscle may become weak and enlarged (systolic dysfunction). The weakened muscle doesn’t pump enough blood forward when the ventricles contract. Or, the heart muscle may become stiff (diastolic dysfunction). The stiff muscle can’t relax between contractions, which keeps the ventricles from filling with enough blood.

Pulmonary edema involves fluid accumulation and swelling in the lungs.

Pulmonary edema is a condition in which fluid accumulates in the lungs, usually because the heart ' s left ventricle does not pump adequately. The build-up of fluid in the spaces outside the blood vessels of the lungs is called pulmonary edema.
