Exercise is an important part of cardiac rehab. Combining exercise
with other lifestyle changes, such as eating a balanced diet and stopping
smoking, reduces the risk of future heart problems.1
An exercise test is usually done before you begin your cardiac rehab exercise
program. This test will show what types of exercise you can safely do and how
soon you can begin to exercise.
Studies show that you can benefit from exercise whether you exercise
at a high intensity for just a short time or at a low intensity for a longer
period of time. If, for example, you are a person who finds exercising
difficult, you still can obtain the benefits of regular exercise simply by
taking a long walk.2
Cardiac rehab exercises can:
- Lower your risk of dying of heart disease.
- Lower your blood pressure.
- Help you control your
diabetes.
- Make your chest pain less severe and happen less often.
- Reduce your symptoms of heart failure.
- Lower your
cholesterol levels. Exercise alone may neither change
cholesterol
plaque buildup that is already in the coronary arteries nor
improve blood flow to the heart. But exercise combined with lifestyle changes,
such as eating a more nutritious diet, stopping smoking, and reducing stress,
can lower cholesterol levels and lower the risk of rupture of cholesterol-laden plaques, which can lead to a heart attack.
- Help you lose weight or maintain your weight. Exercise combined with other lifestyle changes, such as eating a more
nutritious diet, can reduce your body weight (a risk factor for
coronary artery disease). Most important, exercise
helps prevent regaining weight.
Exercise can also improve your quality of life, endurance, and muscle
strength. After 3 months of exercise in a cardiac rehab program, you may
increase your ability to exercise by 30% to 50%.3 Your
daily activities (such as carrying groceries) will be easier to complete. You
may also experience an improved sense of wellness: Exercise can help alleviate
depression, stress, and anxiety.
You will be taught to monitor your heart rate when you exercise. It
is important to keep your heart rate from getting too high. Your doctor will
tell you how fast your heart rate should be with exercise. Self-monitoring is
often used during the last stage of a rehab program, when you continue your
cardiac rehab on your own without close supervision.
Riding a stationary bike, walking on a treadmill, and resistance
training (working with weights) are types of exercise you may do during the
early phases of cardiac rehab.
