Nocturnal cough when lying down with shortness of breath and fast heartbeat with feeling of high blood pressure are symptoms of which disease in a 55 year old male with history of hypercholestrolemia and medication going on and prostate hypertrophy with medicine going on. He has usual cough when he sits on chair with inclined back and mild cough when lie down from past 1 year but it happen only in winters and used to be okay when he covered his throat with a muffler. There was no chest pain yesterday but today the cough again started in evening and while talking also, he was coughing now. Few days ago also, cough happened at night then I gave him monteleukast and levocetrizine combined medicine and then cough suppressed. What is it?
