Heart Failure

What's is it?

Heart failure is a condition in which your heart can no longer provide enough blood to keep up with your body's needs.

Heart failure can be caused by several different problems, including coronary artery disease, cardiomyopathy, heart attack or congenital heart problems.

In many cases, heart failure can be treated effectively with medications. When medications do not help and symptoms become severe, a heart transplant may need to be considered.

What are the symptoms?

There are many symptoms of heart failure, and they may be mild or severe.

One of the primary ways your cardiologist will assess your heart is by a cardiac ultrasound to measure your ejection fraction. This is the percentage of the blood in your heart's left ventricle that is ejected with each heart beat. A normal ejection fraction is between 55 and 65%. Many people with heart failure have an ejection fraction below 40%.

Most common symptoms of heart failure are:

  • Shortness of breath, particularly when exercising
  • Inability to exercise or perform physical tasks
  • Swelling in the legs, ankles or feet
  • Sudden weight gain from retaining fluid
  • Frequent urination late at night

How is it treated?

Medication. Most cases of heart failure are treated with medication. There are many drugs available for the treatment of heart failure, and your cardiologist may prescribe one or more of them.

Implantable defibrillator. Heart failure patients have a higher risk of sudden cardiac death, so an implantable defibrillator may be needed. This device is implanted surgically. If your heart should ever stop suddenly, the defibrillator will shock your heart back to its regular rhythm.

Cardiac resynchronization therapy (CRT). A relatively new treatment, cardiac resynchronization therapy can help your heart to pump more efficiently. A CRT device uses electrical signals to help the heart beat in a more coordinated fashion.
