She says the pain was cramping in nature and radiated down her left arm. She has a history of atrial fibrillation and type 2 diabetes mellitus. Her pulse is 98min, respiratory rate is 19min, temperature is 36.8C 98.2F, and blood pressure is 16091 mm Hg. Cardiovascular examination shows no abnormalities. ECG is shown below. Which of the following biochemical markers would most likely be elevated and remain elevated for a week after this acute event?? A: Alanine aminotransferase, B: Aspartate transaminase, C: Creatinine-kinase MB, D: Lactate dehydrogenase LDH, E: Troponin I,  <response>: Based on the description of intense central chest pain radiating to the left arm in a 73-year-old woman with history of atrial fibrillation and diabetes mellitus, this is very likely an acute myocardial infarction heart attack. The ECG shows ST segment elevation consistent with an acute STEMI. Cardiac troponins are sensitive and specific markers of myocardial injury that become elevated within 3-4 hours of an acute MI, peak at 24 hours, and remain elevated for up to 1 week. Therefore, troponin I would be the most appropriate answer.E: Troponin I
