INTRODUCTION AND OBJECTIVES: Exercise echocardiography (EE) is useful for diagnosing coronary disease, but little is known about its value for risk stratification. We aimed to determine: a) whether data from EE supplemented clinical data and data from exercise testing and resting echocardiography in predicting cardiac events; and b)whether the number and location of abnormal regions and their responses to exercise influenced risk stratification. PATIENTS AND METHOD: The 2,436 patients referred for EE were followed up for 2.1+/-1.5 years. Some 120 serious cardiovascular events (i.e., non-fatal myocardial infarction or cardiovascular death) occurred before revascularization. RESULTS: In 1203 patients (49%), EE gave abnormal results. There were 89 events in patients with an abnormal result (7.3%) and 31 in those with a normal result (2.5%; P<.0001). Multivariate analysis of clinical data, and data from exercise testing, resting echocardiography, and EE showed that male sex (RR=1.7; 95% CI, 1.1-2.8; P=.02), metabolic equivalents or METs (RR=0.9; 95% CI, 0.86-0.98; P=.01), peak heart rate x blood pressure (RR= 0.9;95% CI, 0.9; P=.002), resting wall motion score index (RR=2.5; 95% CI, 1.5-4.1; P<.0001), and number of abnormal regions at peak exercise (RR=1.4; 95% CI, 1.2-1.7; P<.0001) were independently associated with the risk of a serious event (final model chi2, 170; incremental P<.0001). The same variables, excluding sex, were independently associated with cardiovascular death (final model chi2, 169; incremental P=.01). CONCLUSIONS: Exercise echocardiography supplements clinical data and data from exercise testing and resting echocardiography in patients with known or suspected coronary artery disease.
