*7.2.1 Exercise testing*

The American College of Cardiology (ACC)/American Heart Association (AHA) 2002 recommends exercise testing [34] early (2–3 wk) or later (3–6 wk) after hospital discharge is beneficial for framing of an exercise prescription in patients who had MI without (Class I recommendation) or with (Class IIa recommendation) coronary revascularization. An exercise test may also be used after certain period of time in patients who undergo supervised exercise training and CR (Class IIb recommendation). The following points of exercise testing should be noted: The test should be limited to symptoms and use standard exercise testing procedures. The test should be completed while the patient is on medications. e.g., the timing of a β-blocker with respect to the exercise test because it influences the HR response and ultimately on the HR-based Ex Rx. The following section on Ex Rx provides methodology for guiding exercise intensity.

### *7.2.2 Exercise prescription*

The Ex Rx techniques used for the apparently healthy adult population may be applied to many patients with CVD. This section provides recommendations of the Ex Rx for patients with known CVD (**Table 5**).
