What is the value of annual exercise testing in high-risk patients with SIHD?
Yearly exercise testing could be useful in patients with SIHD who have .3% risk of mortality per year, because a marked decrease in exercise capacity or a marked increase in ischemic burden can warrant reevaluation of the medical regimen or interventional plan. Examples of such patients are those with a high-risk Duke treadmill score, patients with an EF ,50% and significant CAD in .1 major vessel, patients with diabetes mellitus, and those with multivessel disease who have not undergone CABG. Some data also suggest that ischemic burden might be useful in targeting ischemia-guided revascularization.
