Stress Echocardiography in the Diagnosis of Coronary Microvascular Ischemia: The Forgotten Old Faithful Tool?

      Ischemia is defined as an imbalance between myocardial oxygen supply and demand—this includes both macrovascular and microvascular ischemia. When patients present with typical angina or equivalents, a clinician can use a battery of tests to assess for ischemia. If positive and symptomatic despite medical therapy, patients are referred for coronary angiography to detect significant epicardial coronary artery disease (CAD) as a cause of symptoms.
