What is the difference between chf and cardiogenic shock?

Degree of severity: CHF means inability of the heart to meet the necessary blood supply to the body and results in fluid congestion due to inadequate forward flow of blood from the heart and build up of back pressure. Cardiogenic shock is an extreme form of CHF where the blood flow from the heart is so poor it results in low blood pressure and damage to multiple organs from lack of blood supply (hence lack of o2.

Cardiogenic shock: Shock is a very severe circulatory impairment where the body isn't getting the cardiac output it needs to function. Cardiogenic shock is when the heart is the cause of the shock. CHF is a less severe heart dysfunction characterized by fluid retention in the lungs and sometimes peripheral tissues. Cardiogenic shock can be the end stage of chf.
