y husbamd is scheduled next week for a stress test becUse of shoetnes of breath its worst should he wait hes on BP meds also for high vlood pressure?

Why? Why would he want to wait? If he's having these symptoms, best to do it straight away.
Don't wait . He should go for his scheduled stress test. It is ok to take most of his BP medications except perhaps a beta blocker on the morning of the test. You must talk to the cardiologist about his medications.
