The increase in cardiac enzymes can occur after fitness, mainly due to the elevation of creatine kinase, which is mainly due to the activity of the muscles during fitness and local muscle damage, generally with a clear history of fitness, creatine kinase will appear very high, while other markers of myocardial injury are mildly increased or normal range. In this case, there is no need to be overly nervous, and do not overdo the strenuous activity in the future when working out, as cardiac enzymes are mildly elevated when working out, and patients do not need to be overly nervous. In the case of severe rhabdomyolysis, the condition requires prompt treatment, but most of them are caused by mild muscle damage, so there is no need to be overly nervous, and it is sufficient not to be too strenuous when working out thereafter.
