Transient cardiac ventricular dysfunction or sudden cardiac deaths have been reported for male athletes participating in marathon racing. Less is known about the myocardial response in females. We examined natriuretic peptides and cardiac troponins in female athletes after a marathon. ⋯ Parameters representing cardiac stress increased in females after a marathon. Different kinetics of natriuretic peptides BNP and NT-pro-BNP post-marathon could be due to their different half-lives and dependence on renal function. The increase of cTnI and cTnT may result from minor myocardial lesions.
