Is myocardial nutrition related to the treatment of cardiovascular diseases?

This is indeed relevant. In cases of myocardial infarction, medications that nourish the myocardium are primarily used to improve the function of cardiomyocytes outside the infarcted area, thereby enhancing overall cardiac function. The mainstay of myocardial infarction treatment involves aggressive administration of antiplatelet agents, lipid-lowering drugs to stabilize atherosclerotic plaques, and blood-activating and stasis-resolving medications. Strict bed rest is required; patients should avoid unnecessary physical activity, emotional stress, or anxiety, and must maintain regular, unstrained bowel movements.
