Introduction: Stress echocardiography (SE) has an established role in the evaluation of symptomatic patients, but its utility in asymptomatic patients is unclear. Current guidelines discourage the use of SE in most asymptomatic patients, citing lack of data to support its use. We therefore sought to describe the yield of SE in a group of asymptomatic individuals according to risk profile. Hypothesis: We hypothesized that SE would rarely be abnormal in asymptomatic individuals. Methods: We conducted a retrospective cohort study of all asymptomatic individuals who underwent exercise or pharmacologic SE between 2003 and 2013. Reasons for SE included screening for CAD, preoperative evaluation, abnormal ECG, coronary calcification, and assessment of established CAD (defined as prior myocardial infarction or coronary revascularization). We grouped subjects using both the 10-year Framingham risk equation and ATP3-suggested categories of low-risk ( 20%) for non-di...
