Measuring Athlete's Risk of Cardiovascular Events 3 (MARC-3) (MARC-3)
Regular endurance exercise is widely known to improve cardiovascular health and reduce the risk of heart disease. Yet several imaging studies have shown that male endurance athletes have a higher prevalence of coronary artery calcification (CAC) and calcified plaque than less active individuals. It remains unclear whether this represents harmful progression of coronary artery disease or a more benign, stable form of atherosclerosis. Understanding this distinction is essential, because coronary atherosclerosis is the leading cause of exercise-related cardiac events in athletes >35 years.
The MARC-3 study is the second long-term follow-up of the original Measuring Athlete's Risk of Cardiovascular Events (MARC) cohort and aims to clarify how lifelong exercise training influences coronary artery health.
The study will:
- examine how long-term exercise patterns relate to the progression of coronary atherosclerosis;
- assess plaque characteristics using artificial-intelligence based quantitative coronary CT angiography (AI-QCT);
- identify biological markers that may link exercise to plaque development; and
- evaluate long-term clinical outcomes, including all-cause mortality and major adverse cardiovascular events (MACE).
Our working hypothesis is that endurance exercise predominantly leads to more stable, calcified plaque, and that mechanisms such as exercise-induced hypertension, inflammation, lipid regulation, and genetic background may provide an explanation for the unexpected results observed in previous studies.

MARC-3 cohort
Participants in this cohort are the surviving and traceable members of the original MARC study, which enrolled 318 middle-aged male amateur endurance athletes between 2012 and 2014.
In the first follow-up (MARC-2), 291 participants were successfully re-examined.
All participants have a lifelong history of regular endurance exercise.
In MARC-3, they undergo repeat evaluation of coronary atherosclerosis, cardiopulmonary fitness, exercise exposure, biomarkers, and genetic factors approximately 12.5 years after baseline.
