Men who have exercised very intensely and for many years are more likely to have calcium deposits and plaque in their heart arteries than those who exercised less, even though they tend to live longer.

Even though elite athletes have more plaque in their hearts, the type of plaque they have is harder and less likely to rupture — which might be why they live longer than you’d expect.

Even though super-active athletes have more plaque in their heart arteries, the plaque they have is harder and less dangerous-looking than the softer, riskier kind seen in less active people.

For older male athletes, how much they exercise overall doesn’t seem to affect whether their heart arteries get more clogged over time—it’s more about how hard they push during workouts.

Men who have trained for decades in marathons and endurance sports are more likely to have calcium deposits in their heart arteries than men who don't exercise much—even if they're otherwise healthy and have no heart disease risk factors.
