Question: I am 75 and confused about what to do. About 15 years ago I was put on
atenolol because I was getting high pulse rates and blood pressure with high exertion. This solved the problem which had not shown up on a treadmill test or a thallium test, it was only found by having me run on the spot for ten minutes.When I retired in 2000 I mountain biked, played tennis in the Florida sun etc with no issues.About three years ago I started getting out of breath more easily, and had some discomfort in the collar bone area, but I have never had any
chest pain or pressure. To shorten the story, I have passed three treadmill tests (top 10% percentile for my age), perfect angiogram,
CT scan on pulmonary arteries, two 64 bit digital CT scans, two thallium treadmill tests, another treadmill test where I was laid down and injected with a chemical that made me breathless,and no blockages more than 50% have been found anywhere.For some reason my breathlessness cannot be duplicated on a treadmill, yet I am done if I start digging up the lawn, sawing wood, doing anything involving bending over or working at arms length. I have see two cardiologists due to insurance changes.When I get really breathless I have to bend over to walk indoors.
Nitroglycerin doesn't have much effect, and I take
Imitrex for
migraine. My BP when I arise varies from 98 to 185 on different days, but usually is normal. My pulse on arising has vbeen as low as 36 and high as 110. I would have expected to be fitted with a pacemaker, but it was only briefly mentioned. My cardiologist now wants me to have an angiogram and I am reluctant as I don't like invasive tests and the chance od MRSA. If all these other tests indicate no problems, are they missing something else?What would you do?
