[|Human|] my neighbor has been coughing up blood after intercourse and has a hard time breathing afterwards.  He has had 3 stents placed in his heart about 1 and 1/2 years ago. He is on plavix and 2 other hearmeds plus baby aspirin.  He has had a chest xray recently that was negative.  Any thoughts of what would cause this??
[|AI|]  Hello, Is it a Frank blood or pinkish sputum. If it's a Frank blood then it has nothing to do with intercourse and it just a coincidence. If its pinkish sputum, then it's possible that he had heart failure and pulmonary edema producing pink frothy sputum. In this case, he'll echo, fluid restriction and other treatment.  There are many reasons for blood in sputum like infection, malignancy or may trauma or some throat lesion. So he'll need one ENT examination, and still nothing is found then needs ct scan of chest.
