Heart failure

Heart failure, also called congestive heart failure, is a condition in which the heart can no longer pump enough blood to the rest of the body.

Learn more about heart failure in our health encyclopedia.

With heart failure, your body makes too many stress hormones. Over time, these hormones can be harmful to your heart.

Tip

Beta blockers are started at low doses and are increased gradually.

Beta blockers, like ACE inhibitors, block the effects of these hormones and reduce the workload of your heart. ACE inhibitors block different hormones than the beta blockers so you get the most benefit from being on both kinds of medicine.

Beta blockers can improve your heart function, decrease the need for hospital stays, and help you live longer. They may also be used for people who have high blood pressure, heart rhythm problems or who have had heart attacks.
