Answer

For question 9, the standard medical guideline for patients presenting with symptoms suggestive of an acute myocardial infarction (heart attack) is to acquire a 12-lead ECG within 10 minutes of arrival at the emergency department. For question 10, cardiac troponin (specifically Troponin I and Troponin T) is the most sensitive and specific biomarker for myocardial injury and is the gold standard for diagnosing a myocardial infarction.
