An elderly man presents to the emergency department with chest pain. He has a history of stable angina and recent onset diabetes mellitus, but now the chest pain comes on with less exertion and takes longer to g0 away. An ECG and cardiac enzymes are ordered. If this man has unstable angina, what are the expected findings on ECG and cardiac enzyme testing? (A) Delta waves on the ECG and elevated cardiac enzyme levels (8) Low voltage ECG and elevated cardiac enzyme levels (©) No changes on ECG and elevated cardiac enzyme levels (D) ST-segment depressions on ECG and normal cardiac enzyme levels (B) ST-segment elevations with Q waves and Normal cardiac enzyme levels
