I'm 62 years old and was diagnosed August 2024 with a "4.1 cm mild ascending thoracic aortic aneurysm".

Have had sonogram, CT scan, PET scan, and Echocardiogram.

The Echocardiogram was only a few days ago and produced what I thought was an amazing 79 measurements.

All I've heard back from the primary doctor is an email stating to be sure and schedule another echocardiogram in 2-3 years

I've put in request to hear from a cardiologist, their perspective on the 79 echocardiogram findings.

This request seems to be meeting with some resistance?

Have a phone call appointment with the primary doctor on Monday 2/3/24 about getting approved to speak with a cardiologist.

Your situation with coughing is a thought that hadn't occurred to me. Glad you mentioned it. I'll add that to my Monday 2/3 phone call appointment questions.

Among my questions is what is an acceptable level of cardio exercise, if any limits?

Is hiking above the 14,000 foot elevation a concern?
