Hi, welcome to HCM.
Fibronodular changes in right upper zone are due to old tuberculous infection. Tuberculous bacilli has predilections for upper zone. It will causes damage to that area which shows fibrosis
on long duration.
Rest of all structure in lung like heart, bone and vessels are completely normal. No need to worry about that.
Also changes are due to remote infection. It will not harm you at present.
Hope I have answered your query.
