If you have just experienced cardiac or thoracic surgery, or you have a surgery scheduled in the near future, then you probably would like to know all you can about cardiac surgery rehabilitation. Depending on the nature of the surgery and what needed to be done, the recovery time for the patient will vary. One thing that typically remains constant in an open heart surgery is the importance placed on the recovery of the wound or sternal closure. Sternal wound dehiscence is something that needs to be avoided at all costs for those recovering from cardiac surgery.
