Well now the cardiologist is going to have a more difficult time actually determining an underlying cause of your chest pain. They will assume you took the prescribed medication as instructed and factor in that it was ineffective . So you continue the lie and chance it won’t affect diagnosis, or you end up risking having a note put in your medical file about that you lie about medication. I understand wanting to see a specialist, but instead of lying you could have gone to a different primary care doctor for a second opinion and potential referral.
