White 50 yo male. 6’2″ tall 174 lbs. Currently experiencing ongoing shortness of breath and dizziness during exercise. No previous history of heart disease, diabetes, cardiovascular disease. Summary from Echo:

Normal diastolic function4.Mild upper normal RV size with preserved systolic function5. Trivial panvalvular regurgitation.6. No indication of endocarditis prophylaxis.
Need to exclude amyloidosis. Performed a lung function test and it was normal. I am currently performing a 24 hour urine test to rule out amyloidosis. No other underlying causes have been discovered, such as sleep apnenia. What are other underlying factors would lead to this condition?
You are in the middle of a diagnostic evaluation, thus I can only comment on amyloidosis, an abnormal protein usually produced by cells in your bone marrow that can be deposited in any tissue or organ.
