Abnormal catecholamines/high total metanephrines

Just recently found this sub. Some background: I am 31, lift weights 3-4 times a week and swim/bike/run. Compete in Olympic distance and half Ironman distance triathlons. Don’t smoke and eat healthy 80-90% of the time. I have had hypertension as well as some other symptoms and my primary care doctor referred me to a cardiologist.

She noted that in some previous testing that my primary care doctor ordered, that my 24 hour urine test came back as “abnormal” for catecholamines and high total metanephrines at 714mcg. She has ordered further testing.

Also to note, I had an abnormal echo with prominent LV trabeculation.

I guess I am looking for further insight on some of these "abnormalities."
