Body has a natural reparative process for healing wounds. Generally wounds take about 6-8 weeks to heal completely. Bones may take a little longer. The new tissues will need some time to get used to the stress and strain of activities of daily life. This process is called the remodeling. It is natural to experience some discomfort during healing and remodeling stages.
The surgical wounds are stitched using special needles and suturing threads. Some materials are bio-degradable or self absorbing. They need not be removed. Some need to be removed after the necessary period (like silk and nylon).
Generally all the wounds of heart operation are repaired using self absorbing stitch materials. These can not be seen outside and need not be removed. Small wounds are sometimes repaired using silk or nylon sutures. These are usually removed just before discharge.
Immediate post-operative period is not the time for heavy exercise schedules. The aim is to get back to routine life style and be active. Let your body decide how much you can exercise! In the first two weeks, walking indoors for 10 minutes each 2-3 times a day along with mild stretching and deep breathing exercises as prescribed by your doctor would suffice. By this time intensity of pain and other discomforts would have settled significantly. After first follow up visit, most patients are advised to walk outdoors and increase the time and speed of walking. By about 4 weeks one should aim to do 1km gentle walk (in about 30 mts) daily. Gradually the speed can be increased. By 8 weeks most patients are able to walk 2km in 30 minutes. Remember, these guidelines differ depending on the pre-operative condition of the heart and the capacity of the heart to exercise. So ask your doctor what is suited for you. Generally, one can get back to normal activities and do full weight bearing on hands by 10-12 weeks. Continue the stretching and breathing exercises. Shoulder joints should be given special attention, as inactivity can make this joint very stiff. This can lead to painful Shoulder Periarthritis or Frozen Shoulder.
One of the biggest concerns in patients’ minds while considering heart surgery is whether he would be able to do the same work as before. On a positive note let me assure you that most of the patients undergoing heart surgery would return to normal physical activity and work pattern in about 3 months. However this depends on certain factors. Most important of these is the pre-operative condition of the heart and the time required for heart to return to normalcy. For example, if the patient has suffered multiple major attacks in the past and the pumping capacity (LV function and Ejection Fraction) has suffered badly, there would be a limit to the level of physical activity possible after heart surgery. Also, recovery is an individual feature and varies from person to person. Mental strength and preparedness plays an important role in smooth recovery. Some people are back to normal in 4 weeks while some take up to 6 months to recover. It does not matter! As a rule most office work can be resumed after 4-6 weeks. Work involving moderate to severe physical activity (driving, lifting weights, prolonged hours of standing etc.) can be resumed only after 3 months. When you get back to work, start with simple and less strenuous tasks and gradually increase the level of activity.
