CORRECT.
SECTION 1: CORONARY ARTERY DISEASE &
MYOCARDIAL INFARCTION PREVENTION
Q1. A patient who is post-myocardial infarction is being discharged.
Which combination of medications has been shown to reduce
mortality and is considered standard secondary prevention?
A. ACE inhibitor, beta-blocker, statin, aspirin
B. Calcium channel blocker, loop diuretic, nitroglycerin, warfarin
C. ARB, digoxin, spironolactone, hydralazine
D. Nitrates, ranolazine, colchicine, vitamin E
Correct Answer: A. ACE inhibitor, beta-blocker, statin, aspirin
Rationale: Secondary prevention after MI includes medications that have
demonstrated mortality benefit: ACE inhibitors (or ARBs) reduce ventricular
remodeling and mortality; beta-blockers reduce reinfarction and sudden
death; statins reduce LDL and plaque progression; aspirin (antiplatelet)
reduces thrombotic events. This combination is guideline-directed medical
therapy (GDMT) for post-MI patients.
Q2. A patient with a history of MI is prescribed a beta-blocker. What
is the primary mechanism by which beta-blockers reduce mortality
post-MI?
A. Vasodilation of coronary arteries
B. Reduction of myocardial oxygen demand and prevention of arrhythmias
C. Thrombolysis of existing clots
D. Increase in cardiac output
