How important is cardiac rehabilitation in the prevention of a 2nd heart attack?

Prevention: This is very important as it has been shown that proper rehab and establishing a healthy life style e.g. No smoking, weight control, exercise, stress control can help prevent a second heart attack or complications.

Heart attack: It is helpful specifically if you have moderate heart disease, heart failure and or haven't excercised in the past and need education on those aspects. The prevention of a subsequent heart attack is based not only on rehab but also controlling risk factors eg diabetes, hypertension, high cholesterol, diet and smoking cessation.
