What is the primary purpose of beta blockers in cardiovascular therapy?

The primary purpose of beta blockers in cardiovascular therapy is to decrease blood pressure. Beta blockers work by blocking the effects of the hormone epinephrine, also known as adrenaline. When beta blockers are administered, they cause the heart to beat more slowly and with less force, which leads to a reduction in heart rate and blood pressure. This effect is particularly beneficial for patients with hypertension, heart rhythm disorders, and certain types of heart disease, as it helps reduce the workload on the heart and prevents complications.

Decreasing blood pressure with beta blockers can also help reduce the risk of heart attacks and strokes, making these medications an essential component of management strategies for individuals with cardiovascular conditions.
