Myocardial ischemia typically results when the heart's demand for oxygen exceeds its supply from the coronary circulation.

Answer: A
 Acute coronary syndromes include conditions such as unstable angina, non-ST-segment elevation myocardial infarction (NSTEMI), and ST-segment elevation myocardial infarction (STEMI), which all result from disrupted blood flow to the heart.

Answer: E
 The mediastinum is the region in the thorax between the lungs that contains the heart, thymus gland, trachea, and esophagus.
