Write answer in between .Q:A 62-year-old woman presents to the emergency department with a 2-hour history of sharp chest pain. She says that the pain is worse when she inhales and is relieved by sitting up and leaning forward. Her past medical history is significant for rheumatoid arthritis, myocardial infarction status post coronary artery bypass graft, and radiation for breast cancer 20 years ago. Physical exam reveals a rubbing sound upon cardiac auscultation as well as increased jugular venous distention on inspiration. Pericardiocentesis is performed revealing grossly bloody fluid. Which of the following is most specifically associated with this patients presentation?? A: Malignancy, B: Myocardial infarction, C: Rheumatoid arthritis, D: Uremia, E: Viral illness,  <response>: This is a clinical vignette describing a 62-year-old woman with acute chest pain that worsens on inspiration and is relieved by leaning forward. She has a history of rheumatoid arthritis, coronary artery disease status post CABG, and breast cancer treated with radiation 20 years ago. On exam she has a pericardial friction rub and increased JVD on inspiration. Pericardiocentesis revealed bloody fluid. The acute presentation along with physical exam and pericardiocentesis findings are most consistent with cardiac tamponade physiology due to pericardial effusion. The effusion is likely hemorrhagic given the grossly bloody fluid. Of the answer choices, malignancy is most likely given her history of breast cancer treated with radiation, which can cause delayed cardiac toxicity and pericardial effusions. The other choices are less likely based on the clinical vignette.A: Malignancy
