Do I need to stop my medications for a cardiac scan?
You must not have any caffeine for 24hrs before the scan. If you already know you have a cardiac condition you will need to ask us or your doctor whether you should stop the medications -this will depend why you are having the test. If the test is for diagnosis (chest pain or shortness of breath) you should (in most circumstances) stop medications for more than 24 hours. If the test is checking the effectiveness of treatment you are already on then it may be appropriate to continue with these medications. If in doubt we suggest you check this with your doctor or failing that with us (please refer to the contact details of the location you are having the test).
