Beta-blockers antagonize beta-1 and beta-2 receptors which are the usual targets of the sympathetic nervous system, including epinephrine and norepinephrine. This results in a decreased heart rate ...

Alpha-1 adrenergic receptors (α1-ARs) play a significant role in the regulation of cardiovascular function, particularly in conditions such as heart failure and myocardial infarction (MI).

Traditionally, beta-adrenergic receptors have been associated with ... which is crucial for energy production in heart cells[1]. This suggests that enhancing β3AR signaling could be a promising ...

Atenolol blocks beta-1 receptors, which are present on the heart. This medication is a beta-blocker, prescribed for high blood pressure and to prevent heart pain and recurrence of heart attacks.
