I would strongly urge you not to have this stress test. You don't need to stress that aneurysm wall. What possible good is a stress test going to do? Does she have reasons for doing this? What are those reasons? Is this going to change something about your care?
Sometimes I wonder where our physicians come up with these ideas? (In my own life time I have avoided a lot of procedures and medical care simply by asking questions and saying no when it made no sense to me.)
Your resting blood pressure seems just a little high. You need to talk to a sub specialist cardiologist that has lots of experience with aneurysms.
