Prospective Athlete's Heart Study

The Pro@Heart (Prospective Athlete's Heart) study is an international multicentre long-term prospective trial. The primary objective of the Pro@Heart study is to investigate the impact of training load (i.e. accurately evaluated in term of type, frequency, duration and intensity) and genotype on the variability of structural, functional and electrical exercise induced cardiac remodeling (EICR) in young competitive endurance athletes. The second objective is to determine how EICR, training load and genotype are associated with physical performance, health benefits and cardiac pathology (e.g. exercise-related cardiomyopathies and arrhythmias) during follow-up over several decades.
