The Princeton guidelines define Intermediate Risk as patients with:
Intermediate or indeterminate risk: evaluate to reclassify as high or low risk
Asymptomatic and ≥3 CAD risk factors (excluding gender)
-> Increased risk for acute MI and death
-> ETT may be appropriate, particularly in sedentary patients
Moderate, stable angina pectoris
-> ETT may clarify risk
MI >2 weeks but <6 weeks
-> Increased risk of ischemia, reinfarction, and malignant arrhythmias
-> ETT may clarify risk
LVD/congestive heart failure (CHF) (NYHA class II)
-> Moderate risk of increased symptoms
Cardiovascular evaluation and rehabilitation may permit reclassification as low risk
Non-cardiac atherosclerotic sequelae (peripheral arterial disease, history of stroke, or transient ischemic attacks)
-> Increased risk of MI
-> Cardiological evaluation should be considered
