Short answer is "being in shape" (even for a marathon) doesn't guarantee you'll be free from heart disease.

Biology is complicated. Nothing GUARANTEES anything.

Being in shape makes you far less likely to die or be injured by a heart attack than being a fat unhealthy pig. Anyone that refuses to accept this is living in denial.

Health matters, exercise matters, and life has random elements but is not random. Choices do have consequences.
