Dear Mr Balaji
Thanks for your query. Cardiomegaly
on chest x-ray should be investigated further. Next step in such cases is ECHOcardiography
. this may be because of heart enlargement, fluid around heart or may be an artifact (expiratory film). But needs to be evaluated. Unfolding of aorta
is common in old age. Blunting of both angles need clinical correlation.
Hope this helps.
