Class III applications are as follows:

  • In cases involving severe comorbidity likely to limit life expectancy, candidacy for revascularization, or both

  • At any time, to evaluate patients with acute MI who have uncompensated CHF, cardiac arrhythmia, or noncardiac conditions that severely limit their ability to exercise (level of evidence: C)

  • Before discharge, to evaluate patients who have already been selected for, or have undergone, cardiac catheterization; although a stress test may be useful before or after catheterization to evaluate or identify ischemia in the distribution of a coronary lesion of borderline severity, stress imaging tests are recommended (level of evidence: C)
