Hi!
36 years old male. Former smoker. Former CrossFit enthusiast.
Is a BNP level of 29 something to worry about or watch?
Recent tests:
Had a Doppler echo (all normal except mildly dilated left atrium 42mm)
I did notice that left ventricle seemed to be upper end of normal range.
2 clear chest X-rays at separate facilities.
Treadmill stress test normal with “good” exercise tolerance
17 day patch monitor nothing other than less than 1% pvc and pac
