Why is adrenaline not the medication for heart failure?

Too heavy on heart: Adrenalin increases heart pumping strength, but also increases the frequency i.e. Runs too fast. Both of these issues increase demand for oxygen by a heart that is usually deprived of adequate oxygen due to coronary heart disease. This leads to arrhythmias and possible heart attack. In short, like beating a tired horse.

Not useful: Adrenaline is only used during cardiac arrest to "restart" the heart. It has a very short half-life and is metabolized very fast. One of the long-term complications of heart failure is caused by too much adrenaline production to try to stimulate the heart. Beta-blocker medications block the long-term effects of adrenaline and reduce mortality from heart failure.

CHF: Adrenaline stimulates the heart and vascular vigorously and can trigger arrhtymias and muscle fatigue worsening the heart failure. We do use adrenaline sometimes during cardiac arrest in the hope it will get things going.
