What does fitness actually do to a heart attack — and its outcome? Most people assume fitness protects the heart. That's partially true. But the bigger story is what a fit heart does during and after a cardiac event.

In this video, we look at how fitness changes the way the heart functions — stroke volume, heart rate range, recovery — and then put two hearts, a fit one and an unfit one, to the test of a myocardial infarction. The results are striking.

We cover the two distinct mechanisms behind most heart attacks, why they feel very different, and then walk through 10 specific factors that give a fit heart a measurable survival advantage. One of them — the antithrombotic effect — is rarely talked about outside clinical settings.

The data is clear: people with good fitness recovering from a cardiac event have a 68% lower long-term mortality risk than those with low fitness. Not exceptional fitness. The kind that lets someone sustain a brisk jog or climb several flights of stairs.
