Not from the heart attack itself. In a heart attack, the heart is deprived of oxygen from the blockage of a coronary artery. This does not usually cause bleeding, but it does cause the death of the muscle cells if they don't get oxygen.
It isn't more critical, the heart muscle itself is simply one of the most important and necessary muscles which we need to survive. Any muscle when deprived of oxygen will begin to die off, in the case of a thigh muscle however it's more likely to just necessitate amputation (to prevent gangrene from rotting tissue) or it would just result in the muscle not working anymore. The only real distinction that if the heart muscle just "doesn't work anymore" you're dead, you can survive without a bicep or tricep, not without a heart.Oxygen is vital to all muscles. Without oxygen cells die. When oxygen is not received to a skeletal muscle, the muscle wil begin to die out and you will feel tightness, cramps and a lot of pain in the effected region. When heart muscle is deprived of oxygen that is what is known as a heart atack. Blood (oxygen) is blocked from the heart and the muscle of the heart (myocardium) begins to die off. If too much of the myocardium dies the heart will not work properly. The heart will begin to go into Ventricalarfibrulation (V-Fib).
The heart is like any muscle in your body, it needs oxygen and nutrients to function, and it gets them through blood. The heart is a very metabolically active muscle as it is working all the time, always in motion, therefore it requires a lot of arteries and veins to make sure enough oxygenated blood gets through to the cells. If the heart cells are deprived of oxygen, they cease to function and die, which is what happens in a "heart attack"; something blocks an artery and blood doesn't reach the cells that depend on it.

Ischamia is the lack of oxygen to a certain part of the body. For example in a heart attack, the heart muscle undergoes ischaemia because blood can't reach the heart muscle cells.
