Exercise echocardiography has been used for 30 years. It is now considered a consolidated technique for the diagnosis and risk stratification of patients with known or suspected coronary artery disease (CAD). Of the stress echocardiography techniques, it represents the first choice for patients who are able to exercise. Given that the cost-effectiveness and safety of stress echocardiography are higher than those of other imaging techniques, its use is likely to be expanded further. Recent research has also proposed this technique for the evaluation of cardiac pathology beyond CAD. Although the role of new technology is promising, the assessment of cardiac function relies on good quality black and white harmonic images.

Background-We sought to identify extensive ischemia on exercise echocardiography (ExE) relative to workload in patients without known coronary artery disease and to investigate whether ExE is useful in predicting outcomes in those with high exercise capacity (≥10 metabolic equivalents [METs]) plus a maximal test (≥85% of their maximal age-predicted heart rate [MAPHR]). Methods and Results-The analysis was performed on 4269 patients who underwent ExE, of whom 3995 achieved ≥85% of their MAPHR. These patients were divided according to the reached workload (<7, 7-9, or ≥10 METs) and compared for ExE results. Outcomes in the group achieving ≥10 METs plus ≥85% of their MAPHR (n=2221) were specifically assessed. Ischemia was defined as new/worsening wall motion abnormalities with exercise. ExE results were different between groups because the METs were lower. Still, among patients achieving ≥10 METs plus ≥85% of their MAPHR, 9.3% had extensive ischemia and 6% multiterritory disease. During follow-up in this subgroup, 108 patients died and 42 had a major cardiac event. Annualized mortality and major cardiac event rates were 0.84% and 0.32% in patients without ischemia versus 2.26% and 0.84% in those with ischemia, respectively (P<0.001 and P=0.002, respectively). Ischemia was an independent predictor of mortality (hazard ratio,

Peak treadmill exercise echocardiography for ischemia detection

Of the stress echocardiographic methods, exercise should be the first choice for patients able to exercise, according to guidelines. Among ExE modalities, treadmill ExE with acquisition of images at peak exercise has several advantages, including high sensitivity and prognostic value. Overall, sensitivity of ExE is around 80%–85%, although figures for peak imaging on the treadmill are 85%–90%. Despite it, guidelines do not mention this method.
