Estudo da isoenzima creatina quinase CKMB sérica em equinos de enduro após exercício físico prolongado

Abstract: ResumoCom o objetivo de estudar a influência do exercício físico prolongado na indução de lesão miocárdica e na desqualificação de equinos em provas de enduro, colheram-se 87 amostras de sangue de equinos adultos Árabes e mestiços para determinação da concentração sérica da isoenzima MB (CKMB), da atividade sérica de creatina quinase (CK) e do índice CKMB/CK. Dividiram-se as amostras da seguinte forma: C (controle, n = 34): equinos em repouso, no dia anterior à competição; G1 (n = 24): equinos que finalizaram … Show more

“…The increase in CK-MB concentration observed in this study was similar to that detected in Arabian horses after prolonged physical exercise [27]. One of the hypotheses that could explain this finding is the occurrence of cardiac hypertrophy due to training, similarly to what takes place in skeletal muscles [2].…”

“…The results obtained show that horses generally have low cTnI concentrations at rest, and that moderate exercise such as a cavalcade induces mild increases in cTnI concentrations, consequently increasing the risk of some degree of myocardial injury. Unfortunately, factors that may predispose individual horses to myocardial injury associated higher in resting animals, when the effect of exercise is not present Michima ,et al [27]. It should be warned that CK-MB levels alone do not produce important information on the cardiac integrity of horses submitted to exercise.…”

“…Esses dados sugerem que houve um leve estresse miocárdico, mas sem signifi cância clínica aparente. MICHIMA et al (2010) não verifi caram aumento da CK-MB em equinos de enduro, tanto os que fi nalizaram as provas como os desqualifi cados por causa metabólica ou claudicação. Os autores acreditam que a utilização da CK-MB como único marcador cardíaco não traz informações relevantes a respeito da integridade cardíaca sob infl uência do exercício.…”

“…Kinaza kreatynowa jest enzymem występującym w wysokich stężeniach w energochłonnych tkankach, takich jak: mięsień sercowy i mięśnie szkieletowe. Składa się ona z 3 izoenzymów: mięśniowego (CK-MM), sercowego (CK-MB) i mózgowego (CK-BB) (5,26,27,33,39,40). Przyczyną wysokiego wzrost aktywności kinazy kreatynowej w krwi obwodowej może być uszkodzenie mięśni, w tym mięśnia sercowego (2,12,19).…”
