    Heart Disease Medicine: How Can It Help You?

    Angiotensin II Receptor Blockers (ARBs)

    This type of heart disease medicine can have these effects:

    • Lower your blood pressure
    • Ease the work of your heart

    ARBs block the action of angiotensin II, a hormone that makes blood vessels tighten. As a result, blood vessels remain relaxed. Blood flows more easily through the vessels. Your blood pressure becomes lower and your heart has to work less to pump blood through them. You may also use an ARB if you can not tolerate ACE inhibitors due to a cough, a common side effect.

    Examples of ARBs include: 



    This type of heart disease medicine can help in these ways:

    • Makes your heart beat more slowly
    • Makes the heart beat with less force
    • Lowers your blood pressure
    • Helps prevent future heart attacks if you have already had one
    • Relieves chest pain
    • Helps your heart beat more steadily

    How do beta-blockers accomplish all this? They 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 works less.

    Examples of beta-blockers include: 


    Calcium Channel Blockers (CCBs)

    This type of heart disease drug is also called a calcium antagonist. CCBs can have these effects:

    • Lower your blood pressure
    • Reduce chest pain (angina)
    • Help lower heart rate

    How do calcium channel blockers accomplish this? CCBs prevent calcium from entering the muscle cells in your heart and blood vessels. This keeps blood vessels from tightening so much and causes the heart to pump with less strength. Your heart rate slows and blood can flow more easily through the vessels. This lowers blood pressure.

    Examples of CCBs are:
