Final answer:
Beta-blockers and calcium channel blockers have shown to have a benefit for facilitating myocyte growth in areas of previous myocardial infarction.
Step-by-step explanation:
The drugs that have shown to have a benefit for facilitating myocyte growth in areas of previous myocardial infarction are beta-blockers and calcium channel blockers.
Beta-blockers are sympatholytic drugs that block the B-receptors associated with vasoconstriction and cardioacceleration. By allowing blood vessels to dilate and keeping heart rate from increasing, they can improve cardiac function in a compromised system. Examples of beta-blockers include metoprolol and propranolol.
Calcium channel blockers are negative inotropic agents that may be administered to decrease the strength of contraction and stroke volume. There are different classes of calcium channel blockers, such as dihydropyridine, phenylalkylamine, and benzothiazepine. These drugs can also improve cardiac function after myocardial infarction.
