These are excellent, for the most part, high normal pulmonary function test results, indicative of neither significant obstructive lung disease, such as emphysema; nor restrictive lung disease, as can be seen with mixed connective tissue disease. Only the borderline DLCO and DL/VA might be indicators of very slight, clinically insignificant emphysema due to smoking and/or lung involvement with the connective tissue disease. These results, including your high normal oxygen saturation, strongly suggest that your shortness of breath is not on the basis of lung disease.
Thankyou for your response. Should I investigate heart related problems when having serious shortness of breath? I really was short of breath. Even at sitting or resting I was short of breath. Makes me feel like I couldn't eat, was really dizzy, edema in ankles with exercise. Since the echo showed borderline pulmonary hypertension , could this be causing my symptoms?
If you want a response, you have to post a new question on a new thread. It does sound like other causes for your shortness of breath should be explored. Heart problems can cause breathlessness. Gastric reflux can be another cause of breathlessness. Your physicians can provide you with other possible causes and help you figure out which one(s) are relevant to YOU.
