Why do patients go to cardiac rehab after having a coronary artery stint placed?
by

1 Answer

Answer :

Most patients go to rehab after a cardiac incident. Heart surgery (and heart attack) takes a lot out of a patient and it takes time to recover and achieve a satisfactory level of activity as well as confidence. Rehab gives the patient an opportunity to recover in the care of professionals. Most patients, left to rehab on their own, would not follow the program, which would lead to more difficulties.
