Which beta receptor blockers are cardio-selective?
Beta-1 receptor-selective blockers like atenolol, bisoprolol, metoprolol, and esmolol only bind to the beta-1 receptors; therefore, they are cardio-selective. [2][3][4] Beta-blockers lower the secretion of melatonin and hence may cause insomnia and sleep changes in some patients. [5]

Beta-2 receptors, with their diverse location in many organ ...

What does alpha 1 do to the heart?
Alpha-1 receptors induce vasoconstriction and increased cardiac chronotropy; this means agonism at the alpha-1 receptors leads to higher blood pressure and an increased heart rate. In contrast, antagonism at the alpha-1 receptor leads to vasodilation and negative chronotropic, which leads to lower blood pressure and decreases heart rate. Some beta-blockers, such as carvedilol, labetalol, and bucindolol, have additional alpha-1 receptor blockage activity in addition to their non-selective beta receptor blockage. This property is clinically useful because beta-blockers that block the alpha-1 receptor have a more pronounced clinical effect on treating hypertension. [6]
