Cardiac Rehabilitation

Condition Basics

What is cardiac rehabilitation (rehab)?

Cardiac rehabilitation (rehab) is a program for people who have a heart problem. It teaches you how to be more active and have a heart-healthy lifestyle. This can lead to a stronger heart and better health. Cardiac rehab can help you feel better and reduce your risk of future heart problems.

The program includes exercise, education, and emotional support. You work with a team of health professionals. The team designs a program just for you, based on your health and goals. Then they give you support to help you succeed.

You will learn how to reduce your risk for heart problems, how to manage stress, and how to eat a heart-healthy diet. By the end of the program, you will be ready to maintain a healthy lifestyle on your own. Cardiac rehab can also help you return to work safely and in a timely manner.

Why is it done?

Your doctor may suggest cardiac rehab if you have a certain heart problem, such as a heart attack, stable angina, heart failure, or heart valve disease. Rehab is also done after certain heart procedures or surgeries. Examples include a coronary angioplasty, coronary bypass, heart transplant, or a heart valve repair or replacement.

What are the benefits of cardiac rehab?

Cardiac rehab can help you have better overall health and a better quality of life. It can help reduce your risk of future heart problems, stay out of the hospital, and manage your symptoms. Rehab can also help you recover from a procedure or surgery.

What Happens

In cardiac rehab, you can learn how to:

  • Manage your heart problem and other conditions you may have, such as diabetes, high blood pressure, and high cholesterol.
  • Exercise safely.
  • Take medicine correctly and safely.
  • Eat a heart-healthy diet.
  • Stay at a healthy weight or lose weight, if you need to.
  • Quit smoking.
  • Manage stress.

Cardiac rehab programs are designed specifically for you and your medical needs.

Exercise in cardiac rehab

Exercise is a big part of cardiac rehab. So before you get started, you may have a full checkup. This will help your team design an exercise program that is safe for you.

Your doctor will give you an exercise prescription. It will give you and your cardiac rehab team guidelines for the frequency, duration, and intensity of your exercise. The prescription will be based on your medical condition and your fitness level.

Your rehab team will keep a close watch on how exercise affects your heart. You will learn how to check your own heart rate when you exercise. By the end of rehab, you will be ready to continue an exercise program on your own.


Phases of Cardiac Rehab

Cardiac rehab may include hospital (inpatient) programs and outpatient programs. Outpatient programs include those in rehab facilities and those that take place in your home.

Cardiac rehab programs usually include:

  • Close monitoring and supervision during the early part of your exercise program.
  • Education and counseling for you and your family. This can help you have a lifestyle of healthy habits. These habits can help lower your risk of having further heart problems.
  • Preparing you to return to work and the activities you enjoyed before your heart problems. You may need to modify work or leisure activities.
  • Taking care of your emotional health. Getting back your emotional well-being and getting help for depression are important parts of cardiac rehab.
  • Making a plan to help you start a safe home exercise program.

Hospital program

A hospital (inpatient) program takes place in the hospital after you have had a heart attack, heart surgery, or other heart problem. This program may include:

  • Seeing how well you can bathe, dress, and groom yourself.
  • Checking your ability to exercise. Your doctor may want you to have an exercise test before you begin your exercise program. This test will show what types of exercise are safe for you and how soon you can begin to exercise.
  • Checking to see which daily activities, such as lifting, you can safely do.
  • Giving you education about managing your heart problem and other health conditions you may have. This may include taking medicines and having a heart-healthy lifestyle.
  • Doing light exercise. This includes walking short distances several times a day.

Outpatient program

The outpatient program is supervised and done in a rehab clinic or facility. You will likely take part in a exercise program. You will receive information and tools to have a heart-healthy lifestyle. You may also get counseling to help you take care of your emotional health.

Home program

Your cardiac rehab might include an exercise program that you do at home.

Maintenance program

This program helps you keep the healthy behaviors and habits that you learned in your outpatient rehab program. It can be done at a facility or in your home.

Why It Is Done

Your doctor may suggest cardiac rehab if you:

Not everyone is a good candidate for the exercise part of cardiac rehab. You may have other medical concerns that prevent your doctor from recommending cardiac rehab. But almost everyone with heart disease or risk factors for heart disease would benefit from the counseling and health education that cardiac rehab provides.

Exams and Tests

Before you start a cardiac rehabilitation (rehab) program, your doctor will check your heart health to see what types of exercises you can safely do. Tests may include the following:

Resting electrocardiogram (EKG or ECG).

This test measures the electrical signals that control the rhythm of your heartbeat. A resting ECG will sometimes show if more testing is needed before you start your exercise program.

Exercise electrocardiogram (ECG).

This test records the electrical activity of the heart. It is done during exercise to evaluate how your heart responds to exercise. Your doctor can use the test results to find a safe amount of exercise for you. This test may also be called a stress or treadmill test.

Echocardiogram (echo).

An echo is a type of ultrasound. It uses high-pitched sound waves to make an image of your heart. The sound waves are sent through a device called a transducer. The sound waves are reflected off the various structures of the heart. This test shows how well your heart is pumping blood and how well your heart valves are working. Sometimes it is combined with an exercise stress test.

Cardiac perfusion scan.

This test estimates the amount of blood reaching the heart muscle during rest and exercise. It is typically done to find out the cause of unexplained chest pain or to find out the location and amount of injured heart muscle after a heart attack.

Ambulatory electrocardiogram (Holter monitoring test).

This test monitors the electrical activity of your heart while you go about your daily activities. Many heart problems occur only during certain activities, such as exercise, eating, sex, emotional stress, bowel movements, or even sleeping. A continuous recording is much more likely to find any abnormal heartbeats that occur during these activities.

You may also have other tests during cardiac rehab. These tests help your doctor see how you are doing. The tests may include checking your blood pressure and weight. You may also have your blood sugar and cholesterol checked.

Cardiac rehabilitation exercise programs are a safe way for people with heart problems to exercise.

Your rehab team will monitor your activity closely. Health professionals will be on hand to deal with any problems you may have. Your rehab team will tailor all of your exercises specifically for you, based on your medical condition and overall health. Cardiac rehab begins slowly at a comfortable pace and may be as gentle as walking on a treadmill.

If you are worried or afraid to be active again, talk to your doctor. Exercise and activity can greatly improve the quality of your life.


Cardiac rehab carries a small risk of complications.

If you have a health problem that makes exercise unsafe, your rehab will not include an exercise program. These health problems include:

Even if you can't exercise or be active, you will benefit from other parts of a cardiac rehab program. For example, you can get help with quitting smoking and reducing stress. And you can get advice on how to eat a heart-healthy diet. This type of education can lower the risk of heart-related death.

Tell your doctor and others on your rehab team about all of the medicines you are taking, especially if they cause any side effects during exercise. Medicines may also affect your ability to participate in cardiac rehab. Some prescribed medicines can change your heart rate, blood pressure, and overall ability to exercise.

Watch for symptoms

When you exercise, be sure that you are aware of signs and symptoms that mean you should stop exercising and contact your doctor.

Knowing how your body is responding to exercise and what physical conditions are normal for your rehab is important. Your rehab team will show you how to keep track of how you feel, what your heart rate is, and what your blood pressure is. This can help you be aware of problems while you exercise. It can also tell you how your heart is improving.

If you have any other physical or medical concerns such as the flu, a backache, or knee pain, it is best that you put off exercising until the problem passes. You should seek medical advice if you have any questions or concerns.

Your rehab team will tell you which symptoms mean you should call for help.
