Final answer:
Aldosterone antagonists like spironolactone and eplerenone are indicated for patients after a STEMI to reduce mortality and improve outcomes by improving symptoms of heart failure and reducing the risk of cardiovascular events.
Step-by-step explanation:
Aldosterone antagonists, such as spironolactone and eplerenone, are used as part of the treatment for patients after a STEMI (ST-elevation myocardial infarction) to reduce mortality and improve outcomes. They are indicated when the patient has heart failure or reduced ejection fraction. These medications block the effects of aldosterone, which can improve the symptoms of heart failure and reduce the risk of cardiovascular events.
