instruction: hi doctor my roommate is in hospital with chest tightness and shortness of breath last week they ended up doing an angioplasty they had not given him the results of any of the tests they had done mostly just an ray and a sonogram they found blockage in the of the circumflex artery and the left anterior descending artery and put in a stent he went home the next day yesterday he started to have shortness of breath again and checked himself into the er at am he has been there ever since they did more rays and found nothing in his lungs and another sonogram for some reason they are refusing to do a it scan saying they would rather just do another angioplasty they said a it scan would not detect any clots I find this utterly absurd I think it is weird that they want to go in and put in another stent without further testing his troponin levels are also normal why do not they think a it is warranted before they do another angioplasty
output: hi revert back with the asked details to a cardiologist online
