My husband had quadruple bypass 2 years ago. After the surgery, but not because of the surgery, he had blood clots that caused him to return to the emergency room. Since then he has been fine except for a tiny little wet cough that is chronic. Sometimes he has this tiny cough even when he s mid sentence. Could this have anything to do with a clogged artery or blood clot.
Hello, I would explain that chronic cough I not usually related to pulmonary embolism.  It could be related to chronic airway inflammation (bronchitis), an adverse effect of his actual therapy (if he is taking any ACE (April, enalapril, etc.) or pulmonary congestion due to heart failure.  For this reason, if he is not taking any ACE, I would recommend performing further tests
