Designwise how much more powerful is a cheetahs heart than a human heart?

I’ve heard that a Cheetahs heart is like a nuclear power reactor compared to other mammals including humans. Can someone explain why or how?

Sprinting is anaerobic (needs little to no oxygen), so the cheetah’s heart actually plays very little into their bursts of speed. Evidence of this is that they get really tired really fast as anaerobic use builds up lactic acid which causes soreness and fatigue, and cheetahs cannot sprint for very long before they are so exhausted they have to stop.

People who say their heart is the reason for their speed are grossly misinformed. The human heart is capable of supporting much higher levels of aerobic activity than a cheetah (or most other animals for that matter) which actually makes the human heart more like the nuclear reactor of the animal world.
