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.
