After a heart attack, when can you resume walking and exercise: Cardiologist explains

Doctors recommend restarting physical activity gradually after a heart attack, rather than staying in bed for long periods. Walking is usually the first step, while climbing stairs and exercising should be increased only after medical clearance.When is it safe to walk and exercise after a heart attack?A heart attack can make people cautious about physical activity. Many patients and their families worry that walking, climbing stairs or exercising too soon could put extra pressure on the heart. However, complete rest for a long time is generally not the goal after a heart attack. Once the heart attack has been treated successfully and the patient is medically stable, doctors usually encourage a gradual return to movement.The timing of physical activity depends on several factors, including the severity of the heart attack, the treatment received, heart function and whether there are any complications. Some patients may be able to start simple movements while still in hospital, while others may need more time and closer monitoring. Speaking to a cardiologist before increasing activity is important, particularly during the first few weeks of recovery.Dr Sanjeev Gera, Sr Director and HOD, Cardiology, Fortis Hospital, Noida, explains how patients can safely return to physical activity after a heart attack.WHEN CAN YOU START WALKING AFTER A HEART ATTACK?If the patient is stable and the heart attack has been successfully treated, gentle movement can often begin within 24 to 48 hours in the hospital. This may include sitting up, standing and taking short walks with medical supervision. Early mobilisation can help prevent weakness and loss of physical fitness. However, the amount of activity should be decided according to the patient's condition and recovery.After returning home, walking is generally considered one of the safest ways to restart exercise. Patients can begin with around 15 to 20 minutes of comfortable walking once or twice a day, preferably as advised by their cardiologist. Dr Gera recommends walking on an empty stomach and gradually increasing the duration based on medical advice.WHEN CAN YOU CLIMB STAIRS?Climbing stairs can usually be introduced once a patient is comfortable walking on a flat surface without symptoms. However, patients should take the stairs slowly and avoid rushing.It is also important to avoid carrying heavy bags or other loads while climbing. If climbing stairs causes chest discomfort, unusual breathlessness, dizziness or extreme tiredness, the activity should be stopped, and medical advice should be sought.The ability to climb stairs comfortably can vary significantly between patients. Therefore, there is no single number of days after a heart attack when everyone can safely start using stairs.WHEN CAN YOU START EXERCISING?Exercise should return gradually rather than immediately after discharge. Vigorous workouts, intense cardio and heavy weight lifting should generally be avoided until the cardiologist gives clearance.Light weights may be considered after around a month in some patients, depending on their recovery and the results of tests such as a 2D echocardiogram. The exact timing, however, should be decided by the treating doctor.Patients should not use another person's exercise routine as a guide because heart function and recovery can differ considerably from one person to another.WHY IS CARDIAC REHABILITATION IMPORTANT?Cardiac rehabilitation is an important part of recovery after a heart attack. It combines medically supervised exercise with guidance on lifestyle and cardiovascular risk factors.A cardiac rehabilitation programme can help patients gradually improve their exercise capacity and confidence while reducing the risks associated with returning to physical activity too quickly. It may also include advice on diet, weight management, smoking cessation and controlling conditions such as high blood pressure, diabetes and high cholesterol.Studies have found that cardiac rehabilitation can improve exercise capacity, quality of life and cardiovascular outcomes.WHEN SHOULD YOU STOP EXERCISING?Patients should pay attention to warning signs while becoming active again. Exercise should be stopped immediately if there is chest pain, unusual or severe breathlessness, dizziness, fainting or a racing or irregular heartbeat.Blood pressure that becomes very high or very low during or after exercise also requires medical attention. Patients should discuss such symptoms with their doctor rather than trying to continue exercising.The aim after a heart attack is not complete rest, but a safe and gradual return to normal activity. Walking can often be the first step, followed by other activities as recovery progresses. The pace should always be guided by the cardiologist, particularly during the early stages of recovery.- EndsPublished By: Smarica PantPublished On: Sep 18, 2026 16:00 IST
