Quizplus · Accepted Answer

Beta-blockers reduce the workload of the heart, which helps to improve oxygen supply and demand balance in patients with acute myocardial infarction. This can prevent further damage to the heart and improve outcomes. Beta-blockers do not act primarily as antihypertensives, they may reduce heart rate, which is a secondary effect. Beta-blockers may also relieve chest pain, but this is not the primary reason for their use in acute myocardial infarction.
