[|Human|] Hi, my dad is not feeling good. He has chest pains  and the pain is coming from left side of his chest. He feels that his left hand is warming up alot and alot of pressure and even his left side of his chest he feels like it is swelling. What do you think he has? Does he need to go to the hospital?
[|AI|]  Hello. Thank you for your question and welcome to Chat Doctor. I understand your concern. I think that if this is a pain that started while resting, he should go to the hospital. There an EKG should be performed, and blood tests should be run, such as troponin and creatine phospholipase (CK) - MB fraction. If they result all normal, then a cardiac stress test, 48 hours after he has been without pain, should be performed, to check if there is an indication of a coronary artery narrowing or blockage. If there is a positive finding, then a coronary angiography would be the reasonable approach. I hope I was helpful with my answer. Take care.
