Even if someone is a super-athlete, having calcium buildup in their heart arteries still means they’re at higher risk for a heart attack—exercise doesn’t cancel out this danger.

Similar Assertions

Even if you’re super fit and exercise a lot, having calcium buildup in your heart arteries still means you’re at higher risk for a heart attack or needing a stent.

92%

If you have calcium in your heart arteries, you’re at higher risk for a heart attack—even if you’re a marathon runner. Exercise doesn’t make that calcium harmless.

86%

If an athlete has a high calcium score on a heart scan (over 100), doctors should treat them like someone with early heart disease — lower their bad cholesterol and test how their heart handles exercise.

85%

Even though endurance athletes and healthy non-athletes have about the same amount of calcium in their heart arteries, the athletes’ calcium levels are higher than 90% of people their age, suggesting their arteries are aging faster from exercise.

80%

Even though endurance athletes have less dangerous soft plaque, their amount of hard, calcified plaque in the heart arteries is about the same as in people who don’t exercise.
