Conversation: The conversation between human and AI assistant.
[|Human|] My husband coughs quite severly when he does any lifting.  He gets short of breath when he does anything sometimes coughing.  He has a PFT test done and said he was normal for not having COPD,  I have it.  They said his heart could make him do this, is it possible?
[|AI|]  Yes, when your heart pumping is on the lower side there be some collection of fluids in lung spaces causing cough with expectoration and breathlessness, particularly the cough increases while he lies down flat in bed or at night / early morning and the breathlessness is more when he exerts himself. The best way to rule that out is getting a 2 d echocardiography which will give us an idea of the heart function. Let me know if any clarification needed in this context Regards Chat Doctor.
