If a person has chf and is not well enough to endure a heart transplant how long cana person live even if they have a defibrillator.

Severe CHF: You should discussed with your cardiology. It's a very complex question. There is no definite life span documented. Depend on the severity and the stage and treatments already attempted. In the us CHF is known to cause 55, 000 deaths each year. Prognosis poor if patients don't follow treatment recommendations. In my humble opinion prognostic studies not very reliable. Do not get disheartened.

Highly variable : & answer is best delivered by the treating cardiologist.
