Patients entering this module should already have been evaluated and treated using other modules in this guideline. This module G provides assistance in identifying areas for which there are effective interventions that reduce the risk of future coronary events.

Candidates for secondary prevention of IHD are patients who have a history of clinical coronary disease. Generally accepted criteria for a diagnosis of coronary artery disease (CAD) include the following:

• Prior myocardial infarction (MI) and/or pathologic Q-waves on the resting electrocardiogram (ECG)
• Typical stable angina in males oldeer than 50 years of age 50 or females older than 60 years of age
• Cardiac stress test showing evidence of myocardial ischemia or infarction
• Left ventricular (LV) segmental wall motion abnormality by angiography or cardiac ultrasound
• Silent ischemia, defined as reversible ST-segment depression by ambulatory ECG monitoring
• Definite evidence of CAD by angiography
• Prior coronary revascularization (percutaneous coronary intervention or coronary artery bypass graft [CABG] surgery)
