Cardiac markers (BNP, NT-pro-BNP, Troponin I, Troponin T, in female amateur runners before and up until three days after a marathon.

Abstract

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.
