<s>[INST] When I lay down on my back for a while or durring the night my chest feels heavy and full. I cant lay for very long in this position with out it start being very uncomfortable. Sometimes I get some sharp pains in my chest that come and go. Also have a cough that is dry and random. I have had PVC diagnosed by a cardiologist. I also have high blood presure. Lately around 150/85 Just trying to see if the pain and heaviness in my chest is related to my heart. [/INST] The history you suggests fits in what we call orthopnea,  I would strongly  suggest you to get a 2d echo to know for two things the ejection fraction and diastolic dysfunction grading,  it should rule out cardiac part.  If abnormal do consult your cardiologist.  If normal mostly it is pleuritic(related to lungs)  causing dry cough </s>
