Good morning from Las Vegas..Does anyone know if COPD would enlarge our heart? Went and has a C T scan for lungs and it showed my heart is enlarged..My lungs are doing not so bad but now I have appointment to see a heart doctor..Pulmonary doctor was as concerned for my lungs as for my heart..Seems like you have a test for one thing and another shows up..I'm 68 now and have been dealing with COPD for many years...When I moved from Colorado to here I can breath better..But now something else to deal with..Everyone continue to put your health first..
