Hi and thank you so much for this query. It is possible for prednisolone to cause gastritis that can manifest as chest pain. however, troponins are specific to the heart and often signal a heart problem that I will think her heart need to be investigated further for a possible heart disease like myocardiac infarction. The troponins levels cannot be justified by the individual medications or combinations. I hope you find this useful. I wish you well. Feel free to request for more information and ask ore questions should need be. Thanks.
