<s>[INST] Hello I have a question regarding a health issue my fiancee just ran into. She was having pain in her chest several times last year and we kind of ignored it because I told her it was probably cramps or a pinched nerve. About a month ago the pain came back and worse then usual. The pain was in her left side of her breast, left arm and left side of her back. It got real bad 2 weeks ago and she had to go to the hospital. The doc told her it seemed like a minor heart attack and then said it might even be a pinched nerve in her some where where her ribs are, A blood test came back and we found out her main viens going from and to the heart are built up with calcium and she would have to do an "infusion" therapy once and we just wanted to know about this procedure. And this is being done over here in germany. [/INST] Hello! Welcome no Chat Doctor! I passé through your fiancées medical history and would like to explain that it is necessary a careful differential diagnosis to precisely clarify the issue of her recurrent chest pain. After checking her resting ECG, cardiac enzymes (CK-MB, Troponin), cardiac ultrasound, and chest X-ray, it is necessary to perform a cardiac stress test which could come on different modalities (exercise cardiac stress test, stress echo, nuclear perfusion cardiac stress test [CAROLINE]. Another option would be to undergo through a coronary Anglo CT. If sufficient data are Chat Doctor. You need to discuss with her attending doctor on the above-mentioned issues. Hope to have clarified your uncertainties! Kind regards, </s>
