An echocardiogram, or echo, is a heart ultrasound. It uses sound waves to create an image of the heart. Doctors can use this image to diagnose heart failure, as well as assess whether heart failure has progressed.
Heart failure is when the heart
An echocardiogram uses sound waves to create an image of the heart. This allows a doctor to see how effectively the heart pumps blood.
In heart failure, the heart
This article explains how echocardiograms help detect heart failure. It also details what results can mean, overall signs of heart failure, treatment, and more.
Heart failure means the body is not getting enough blood from the heart. This
- Reduced ejection fraction: This means that the heart pumps out 40% less of the blood inside of it. It happens when the heart muscle cannot effectively contract. This reduces the ability of the heart to pump blood to the body. Doctors also call this systolic heart failure.
- Preserved ejection fraction: This means that the heart muscle contracts strongly enough, but the ventricles cannot fully relax. This slows the release of blood from the heart, reducing the rest of the body’s access to blood. Doctors call this diastolic heart failure.
This image can show the heart’s ejection fraction. It may also show damage to the heart, including the ventricles, that can reduce the ability to relax in a person with a standard ejection fraction.
It can also identify other potential causes of heart disease symptoms. A doctor may recommend an echocardiogram if a person experiences the following:
As an echocardiogram creates an image of the heart, it allows doctors to see:
- how blood travels through the heart
- how quickly blood moves through the heart
- how well the various chambers of the heart work
A doctor may recommend an echocardiogram if a person shows any signs of heart disease. Some signs of heart failure that may warrant testing include:
- Shortness of breath: A person may have breathing issues when exerting themselves. As the disease worsens, they may have difficulty breathing when relaxing or lying down. They may wake up gasping for air.
- Swelling: A person may have swelling, especially in the legs or ankles.
- Fatigue: A person may have low energy. This can affect their ability to participate in daily activities.
- Coughing: A person may have a chronic cough or a cough that worsens when lying down.
- Chest congestion: A person may have feelings of congestion in their chest.
- angiotensin-converting enzyme (ACE) inhibitors
- angiotensin receptor neprilysin inhibitors (ARNIs)
- angiotensin II receptor blockers (ARBs)
A doctor may recommend that a person also makes any necessary lifestyle changes, such as:
Heart failure is a long-term condition that may shorten a person’s life. A
A person’s survival depends on factors such as:
- the severity of and cause of heart failure
- access to treatment
- overall health
A heart-healthy lifestyle can help prevent heart failure and other forms of heart disease.
- managing heart disease risk factors — for example, by treating any other condition such as diabetes
- remaining physically active
- minimizing alcohol consumption
- quitting smoking
- following a balanced diet low in sodium and trans fats
- taking medications to treat chronic medical conditions such as high blood pressure
An echocardiogram can help determine what is causing symptoms of heart failure. It can diagnose how severe a person’s heart failure is, assess whether they have other types of heart disease, and may help with guiding treatment decisions.
The test is painless, safe, and noninvasive. People with any heart disease symptoms should talk with a doctor about scheduling testing.
