Many people diagnosed with “heart disease” often worry that exercising will make them too tired, cause heart failure, or lead to complications during activities, so they choose to stop exercising. In fact, most heart disease patients can exercise safely if under proper guidance, which is very beneficial for long-term heart function.
Regular exercise helps strengthen the heart muscle, improves circulation efficiency, reduces the chance of recurrent heart attacks, and improves quality of life both physically and mentally.
Why heart disease patients should exercise
- Helps strengthen the heart Appropriate level exercise improves heart pumping efficiency, enhances heart function, and reduces the heart’s workload in daily life.
- Better control of risk factors Physical activity helps reduce blood lipid levels, blood pressure, blood sugar, and helps control weight, which are important factors in heart disease.
- Prevents symptom flare-ups As the body becomes stronger, the chances of fatigue, chest pain, or arrhythmia decrease, and it helps reduce the risk of acute heart attacks.
- Reduces stress and improves sleep Exercise stimulates happiness hormones, reduces anxiety, improves mental health, and helps heart patients sleep better.
Which heart disease patients should exercise
Most heart disease patients can exercise, such as patients with controlled coronary artery disease, post-balloon angioplasty/bypass patients (should exercise according to cardiac rehabilitation programs), some types of arrhythmia patients, and stable heart failure patients except in some cases where exercise should be avoided until evaluated by a doctor, such as recurrent chest pain, acute shortness of breath, severe arrhythmia, or recent acute heart attack.
Exercise principles for heart disease patients
1. Start slow – gradually increase Do not exercise intensely immediately. Start with light levels such as walking 10-15 minutes, then gradually increase time and intensity.
2. Choose appropriate types of exercise For heart disease patients, choosing the type of exercise is very important because safety, continuity, and benefits to the circulatory system must be considered. Safe types of exercise for heart patients include:
- Brisk walking is the safest exercise for heart patients, suitable for beginners, easy to control intensity, and appropriate for all ages.
- Cycling is suitable for those with knee problems because it has low impact and improves circulatory system function well.
- Swimming is an aerobic exercise that uses many muscle groups, has low joint impact, helps practice steady breathing, and increases fitness without excessive fatigue.
- Slow treadmill walking is suitable for patients who want to control speed and incline, easily control intensity, and is safer than outdoor walking (reduces risk of tripping and falling).
- Light yoga/Pilates is suitable for heart patients who want to improve flexibility and muscle strength, help control breathing, and reduce stress.
- Light aerobic (Low impact) is suitable for those who want slow rhythmic exercise without much impact, using movements without jumping to continuously increase blood flow and reduce injury risk compared to high-impact aerobics.
Exercise that requires heavy muscle exertion, such as heavy weightlifting or activities requiring prolonged breath-holding, should be avoided as they cause sudden high blood pressure.
3. Use the “Talk Test” principle If exercising at an appropriate level, you should be able to speak briefly without excessive breathlessness. If you cannot talk or catch your breath, it means you have exceeded the limit and should reduce intensity immediately.
4. Exercise at least 150 minutes per week divided into 20–30 minutes per day, 5 days a week, without abnormal symptoms.
5. Warm up – cool down every time Warm up 5–10 minutes and cool down 5–10 minutes help reduce the chance of arrhythmia.
Activities to avoid
For safety, heart disease patients should avoid activities that cause sudden high blood pressure or make the heart beat too fast and strong, such as
- Heavy weightlifting
- Weight training requiring straining or breath-holding (Valsalva maneuver)
- CrossFit or high-intensity interval training (HIIT)
- Competitive sports
- Activities requiring sudden muscle exertion
Warning signs to stop exercising immediately If any of the following symptoms occur, stop immediately and see a doctor promptly.
- Chest tightness or pain
- Shortness of breath or unusual fatigue
- Dizziness, lightheadedness, palpitations
- Excessive sweating or pale face
- Cramping pain in the neck, shoulder, left arm, or jaw
Cardiac Rehabilitation – Safe exercise under medical supervision
Heart patients who have recently experienced emergencies such as acute heart attacks or heart surgery should start exercising under a cardiac rehabilitation program (Cardiac Rehab), which includes
- Assessment of heart function (e.g., Exercise stress test, CPET, VO₂ Max)
- Personalized exercise planning
- Care by a team of cardiologists, specialized nurses, and physiotherapists
- Close monitoring of symptoms to improve heart function, reduce recurrence risk, and increase confidence in daily life
Even with heart disease, you can exercise safely
Exercise is not prohibited for heart disease patients if done appropriately. It helps strengthen the heart, reduce the chance of recurrent heart disease, and greatly improve quality of life. Patients should start gradually, choose suitable activities, and always watch for warning signs.
