What causes chronic cough while suffering from laryngitis?
Patient: My husband has had CHF since 2000.  His heart is working at 25% and he also has COPD.He recently learned that his heart is larger than past scans have shown.  He also has a damaged nerve that has caused laryngitis. He has a horrible cough that gets worse when he lays down.  Could this be caused by his enlarged heart?  He has had a pulmonary function test and found that it has not gotten worse since the last test over a year ago. Doctor: Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.  Yeah, surely that symptom you describe is called orthopnea it occurs due to in lying down pre-load is increased and heart can't pump it out and that lead to pulmonary plethora which irritate bronchi and cause cough. Cardiologist opinion should be taken.  Hope I have answered your query. Let me know if I can assist you further.
