I have been having s.o.b. and chest pain upon slight exertion for a long time. Have had heart cath and no clogged arteries. My lung spirometry test showed diffusing capacity of 64% of predicted. All other tests okay except some Afib. Could the low diffusing capacity be causing my problems and is there anything one can do about it??? The spirometry and plethysmographic lung volumes are within
normalNormal saline flush limits.
Thank you for your response.
