Cardiac troponin T elevations, using highly sensitive assay, in recreational running depend on running distance

Abstract: We found, using a novel hs-cTnT assay, the distance of recreational competitive running to be positively related to asymptomatic increases in cTnT post-run concentrations. In contrast, NT-proBNP showed no increase. In addition, the data indicated that a relatively short running distance of 5 km resulted in cTnT release of untrained participants, in contrast to trained participants, which underlines the necessity of sufficient training. Further effort is needed to clarify the significance of exercise-induced ca… Show more

“…These include a multitude of acute cardiac and non-cardiac conditions that may all present with both an elevation of cTn over the 99th percentile as well as dynamic changes in cTn concentration. No algorithm alone can distinguish with certainty AMI from other acute cardiac conditions such as myocarditis, arrhythmias, acutely decompensated HF and non-cardiac conditions such as pulmonary embolism or even strenuous exercise [72] in perfectly healthy individuals. A combination of clinical judgment, additional biomarkers, and diagnostic procedures may have to be employed to arrive at the correct diagnosis.…”

“…Thus, elevated cTn may be detected in conditions other than ACS (the Table), including heart failure, cardiomyopathies, myocarditis, renal failure, tachyarrhythmias, and pulmonary embolism, and even after strenuous exercise in healthy individuals. 8 …”

“…Uma metanálise de 26 estudos demonstrou que ocorre elevação da troponina em aproximadamente 50% dos participantes de provas de endurance 20 . Desta forma, a maioria dos estudos mostra aumentos significativos de troponina cardíaca em grupos heterogêneos de atletas após completar uma maratona ou ultramaratona, positivamente relacionados a distância da competição realizada 8,21 . Outros estudos analisaram as características dos sujeitos, do exercí- cio e o status de hidratação na liberação de troponinas cardíacas após exercícios de longa duração 22,23 .…”

“…Durante a realização de exercícios com menor duração (5 km), indivíduos não treinados têm aumentos significantes na concentração de troponina cardíaca T, em contraste aos indivíduos treinados. Entretanto, quando comparados com indivíduos que realizam exercícios extenuantes, essa liberação tem menor magnitude, concordante com o verificado na presente pesquisa, quando verificou-se que o tempo de prova tem relação com a liberação de troponinas após exercícios, demonstrando que houve uma maior demanda daquele miocárdio menos adaptado que foi exigido por um maior período de tempo 21,24 . A liberação de troponina decorrente de dano patológico pode ser dividida em três categorias: lesão isquêmica cardíaca primária, descrevendo a liberação de troponina devido à injúria causada pela ruptura de placa arterial coronariana e oclusão coronária; lesão isquêmica cardíaca secundária, que descreve isquemia miocárdica com injúria dos cardiomiócitos e ausência de ruptura de placa aterosclerótica derivadas do aumento de demanda miocárdica de oxigênio que supera o suprimento de oxigênio miocárdico e, lesão cardíaca não isquêmica, diagnosticada através da liberação de troponina causada por dano direto ao miocárdio.…”
