"Will I ever be able to exercise again?" It's one of the most common questions I hear from patients recovering from a heart attack, bypass surgery, or other cardiac event. The fear is completely understandable — but the answer, for the vast majority of patients, is a resounding yes.
In fact, structured exercise is one of the most powerful treatments available for heart disease. Here's what the evidence says and what cardiac rehabilitation at Healing Hands involves.
What is Cardiac Rehabilitation?
Cardiac rehabilitation is a supervised programme of exercise, education, and lifestyle support designed to help people recover from heart disease and reduce the risk of future events. It is recommended by cardiology guidelines worldwide following heart attack, coronary bypass surgery, valve repair or replacement, heart failure, and certain arrhythmias. Despite strong evidence, it remains underutilised — often because patients and families fear that exercise after a heart event is dangerous.
The Evidence: Exercise Saves Lives
Multiple large clinical trials have demonstrated that cardiac rehabilitation reduces mortality from cardiovascular causes by 20–25%, decreases hospital readmissions, improves exercise capacity and quality of life, reduces symptoms of depression and anxiety, and helps patients return to work and daily activities faster. Exercise achieves these benefits by strengthening the heart muscle, lowering blood pressure, improving cholesterol levels, reducing inflammation, and training the heart to work more efficiently.
Phase 1: Inpatient Rehabilitation
Phase 1 begins while the patient is still in hospital. Our physiotherapists work with patients to safely get them sitting up, walking to the bathroom, and managing stairs — activities that feel daunting after a cardiac event but are essential for safe discharge home. Breathing exercises, gentle limb movements, and early mobilisation are the focus.
Phase 2: Supervised Outpatient Programme
Once medically stable at home, patients begin Phase 2 — typically within 2–4 weeks of discharge. Supervised sessions include a structured aerobic exercise component (usually walking or cycling), resistance exercises for the limbs and trunk, and monitoring of heart rate, blood pressure, and symptoms throughout. Our physiotherapists are trained to recognise warning signs and adjust exercise intensity to keep you safe.
Phase 3: Long-term Maintenance
The goal of cardiac rehabilitation is not short-term recovery but permanent lifestyle change. Phase 3 supports patients in maintaining a physically active lifestyle independently. You will leave with a personalised home exercise programme, an understanding of your target heart rate zones, and the confidence to exercise safely for life.
Warning Signs to Watch For During Exercise
Always stop exercising and seek medical attention if you experience chest pain or tightness, severe shortness of breath, dizziness or lightheadedness, heart palpitations or irregular heartbeat, or unusual fatigue. These symptoms are uncommon during properly supervised rehabilitation — but knowing what to watch for gives patients and families the confidence to exercise safely.
Fear of exercise after a cardiac event is natural — but it should not prevent you from accessing one of the most effective treatments in modern medicine. Our cardiothoracic physiotherapy team will guide you through every step, from your first supervised session to living an active, fulfilling life.
