[|Human|] I enjoy singing in the choir at church and have experienced slight shortness of breathe near endings, then I have tightness in chest. I have had some heart issues but my cardiologist recently did a cath and said no problems. I then had an endoscopy and dr found nothing. I have had this issue for a while now and still trying to determine what the problem is.
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. First no need to worry about heart diseases because your angiography was normal. We should rule out lung diseases (asthma or bronchitis) for your symptoms. So get done clinical examination of respiratory system and PFT (Pulmonary Function Test). If PFT is also normal then no need to worry about lung diseases. Sometimes stress and anxiety can also cause similar symptoms. So avoid stress and tension, be relaxed and calm. Don't worry, you will be alright. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
