How do beta-blockers work in treating heart disease?

ANSWER

Beta blockers prevent the hormone adrenaline from working. When adrenaline is blocked, your heartbeat slows down. Your heart can't pump so hard. This makes blood go through your vessels with less force. The pressure inside your blood vessels drops. Your heart doesn't have to work as hard. This helps prevent future heart attacks if you have already had one, relieves chest pain, and helps your heart beat more steadily.
