Patients with unstable angina and the following clinical characteristics should be referred for immediate cardiac catheterization:

  • Cardiogenic shock

  • Severe left ventricular dysfunction

  • Angina refractory to medical therapy

  • Acute mitral regurgitation

  • New ventricular septal defect

  • Unstable tachyarrhythmias

Invasive versus conservative therapy

It has been questioned whether patients who have unstable angina but lack the clinical characteristics listed above receive greater benefit from an invasive strategy than from conservative management.
