Do adjunctive medical therapies improve survival in the treatment and secondary prevention of acute myocardial infarction?
Aspirin, beta blockers, ACE inhibitors, and lipid-lowering agents are effective adjunctive therapies that improve survival post-myocardial infarction, while magnesium, antiarrhythmics, and calcium-channel blockers do not.
Postmyocardial infarction (MI) survival has been steadily improving. This improvement has been due, in part, to the actions of the adjunctive medical therapies for the treatment of MI. Aspirin, beta blockers, angiotensin-converting enzyme (ACE) inhibitors, and lipid-lowering agents have been shown to improve survival in the treatment and secondary prevention of MI. Nitrates have beneficial effects as well. These medications complement the reperfusion strategies through different mechanisms. Other adjunctive medical therapies, namely magnesium, antiarrhythmic agents, and calcium-channel blockers, have not been shown to improve mortality with routine post-MI use despite their theoretical benefits.
