Which of these treatments is NOT typically used for myocardial infarction?

Insulin is not typically used as a treatment for myocardial infarction (MI). Instead, insulin is primarily utilized for managing blood glucose levels in patients with diabetes. While patients with diabetes who experience a myocardial infarction may receive insulin to control their blood sugar, it is not one of the direct therapies aimed at treating the heart attack itself.

In contrast, thrombolytics are agents used to dissolve blood clots that can block blood flow to the heart, a key factor in the occurrence of myocardial infarction. ACE inhibitors are commonly prescribed after an MI to reduce the workload on the heart, improve cardiac function, and lower blood pressure. Beta-blockers also play a critical role by decreasing heart rate and blood pressure, which helps to reduce myocardial oxygen demand and improve outcomes following an MI. Each of these treatments has a clear and immediate purpose in addressing the pathophysiology and consequences of a heart attack, whereas insulin's role is not focused on the immediate cardiac intervention.
