Question: I am a 76 byear old male with a Hiatal Hernia. As a child had diptheria, scarlet fever,mumps, chicken pox, measels etc.Currently get short of breath easily when working involving bending, or extensive use of arms for sawing etc. Can walk 2 miles before getting breathless.I have been taking atenolol for high BP.In the last 2 years I have undergone treadmill tests (top10percentile for my age), Thallium treadmill tests, A test where was injected with a XXXXXXX that made me feel I couldn't breathe instead of using the tread mill and pictures taken, 2 64Bit digital CT (tumography?) scans, echocardiagram, carotid ultrasound and nothing was found except a small amount of plaque(45%) in the left ventricular artery. Nitro doesn't make much difference when I get breathless, and I don't get chest of left arm pain. My Cardio now wants me to undergo an angiogram. I don't feel this is probably necessary, also I suffer from panic disorder so the thought of being in the hospital for several hours terrifies me. At 76 should I just keep taking my meds and forget more tests?I hope that this website does not mean you have to give a CYA answer.I do plan to have some pulmonary testing done at a medical friend's fathers suggestion, but the angiogram is scheduled before I can do that.
