The assessment of myocardial perfusion (MP) and wall motion (WM) using contrast dipyridamole echocardiography (cSE-WMP) improves the sensitivity to detect coronary artery disease and the stratification of cardiac events, but its long-term value for fatal and nonfatal ischemic cardiac events, also with respect to patients undergoing revascularization or not, remains to be determined.
cSE-WMP, with both contrast MP and WM assessments, provides independent, incremental prognostic information regarding ischemic cardiac events at 5 years in patients with known or suspected coronary artery disease. Revascularization reduces cardiac events after an abnormal cSE-WMP, resulting in outcomes not different from those in patients with normal cSE-WMP.
