Unstable Angina

Unstable angina is defined as having three possible presentations: Symptoms of angina at rest (usually prolonged >20 minutes), new onset (2 months) exertional angina of at least class III in severity, recent (2 months) acceleration of angina as reflected by an increase in severity of at least one class to at least class III.

In most, but not all, of these patients, symptoms will be caused by significant coronary artery disease (CAD). A diagnosis of unstable angina requires determination of the likelihood of CAD and assessment of the severity of presentation. Patients considered to have ongoing manifestations of unstable angina should receive intensive medical management. The goals of this phase of care are to relieve pain and ischaemia and to prevent the progression of the underlying disease process to MI or death.
