High-Volume Physical Activity and Clinical Coronary Artery Disease Outcomes: Findings From the Cooper Center Longitudinal Study.

Cohort Study
Human
2025 May 6

People who exercised a lot — like marathon runners — didn’t have more heart attacks than those who exercised a little, according to this big, long-term study. So, intense endurance training doesn’t seem to raise the risk of heart attacks.

Effects of Long-Term Endurance Exercise on Cardiac Morphology, Function, and Injury Indicators among Amateur Marathon Runners

Cohort Study
Human
2023 Jan 31

The study looked at runners who trained hard and ran marathons, and found their hearts got tired and showed temporary signs of stress, but none had heart attacks. So, running long distances doesn't seem to cause heart attacks.

The cardiac troponin response following physical exercise in relation to biomarker criteria for acute myocardial infarction; the North Sea Race Endurance Exercise Study (NEEDED) 2013.

Cross-Sectional Study
Human
2018 Apr

After a long bike race, many riders had blood markers that look like a heart attack, but doctors confirmed they didn’t actually have one — so the race didn’t cause heart attacks, even though it made their blood look like it did.

High-volume, high-intensity endurance exercise increases coronary artery plaque burden without increasing all-cause or cardiovascular mortality risk in otherwise healthy individuals.

The presence of increased coronary artery plaque in high-volume endurance athletes is not associated with a higher incidence of clinical cardiovascular events such as myocardial infarction or cardiac death.

High-intensity endurance exercise, when accumulated over long durations, is associated with a significantly increased prevalence of coronary artery plaque, an association not detected using self-reported exercise metrics.

Doing short bursts of intense exercise might boost heart fitness more than steady, moderate workouts for people with heart disease — on average by a small but measurable amount.

Even after accounting for things like cholesterol and blood pressure, the more hours someone spends training over the year, the more likely they are to have plaque in their heart arteries.
