Risk assessment strategies may also vary according to a patient's clinical phase, but for patients with known CAD, there is no universally accepted approach.4

Suspected CAD (may be phase 1 or 2)
For patients with suspected CAD, an initial clinical evaluation can help determine risk and diagnose CAD.4

Patients with chest pain should receive a thorough history and physical examination, a detailed assessment of symptoms, and determination of risk factors.4

Known CAD (may be phases 1 to 3)
For patients with known CAD, a comprehensive clinical assessment can help determine risk and patient prognosis.4

In symptomatic patients, periodic follow-up assessments are important to reassess ischemic burden and determine effectiveness of any therapeutic regimens or risk factor modifications, particularly when the clinical status of the patient changes.4

Patients with CAD who have accelerating symptoms or decreasing functional capacity should be quickly reassessed.4

ACS (phase 4)
Patients with ACS (including intermediate- or high-risk unstable angina or myocardial infarction) follow a different pathway and should be sent to the nearest appropriate emergency department for immediate care.5
