Physical therapists are key members of the cardiac rehabilitation treatment team. Patients who have had cardiac surgery or who have suffered a heart attack will be seen by a physical therapist for a comprehensive evaluation and cardiac rehabilitation. They will assess their patient's vital signs during activity and set parameters for exercise and walking while recuperating in the hospital. Prior to being discharged from the hospital, the physical therapist will develop a personalized exercise program outlining the recommended level of activity for when patients return home. Patients who have had cardiac surgery also have the opportunity to attend a patient education group several times a week, which gives patients an opportunity to ask questions about their activity levels and recovery.
