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.
