“…23 Previous studies with exercise echocardiography have indicated that the imaging component of this test adds incremental and independent information to the results of standard exercise testing. [7][8][9][10][11][12] A normal exercise echocardiogram is associated with a risk of Ͻ1% per year over the first 6 years of follow-up, with a subsequent small increase that most likely reflects progressive coronary artery disease.…”

“…[7][8][9][10][11][12] Previous studies have suggested that the predictive value of a negative test is very high, although the predictive value of a positive test ranges from 17% to 35%. Echocardiographic identification of ischemia is an independent predictor of subsequent events, with these data being incremental to the prognostic information supplied by exercise testing.…”

Background-In studies generally involving short follow-up, exercise echocardiography has been shown to predict composite end points. We sought to study the prediction of mortality with this test and to devise a strategy for combination with standard exercise testing. Methods and Results-Clinical, exercise testing, and echocardiographic data were collected in 5375 patients (aged 54Ϯ14 years, 3880 men) undergoing exercise echocardiography. The Duke treadmill score was derived from the results of treadmill exercise testing. Resting left ventricular (LV) function and the presence and severity of ischemia were interpreted by expert observers. Follow-up at 10.6 years (mean 5.5Ϯ1.9 years) was complete in 5211 patients (97%

30.000 mmHg.bpm; desses, 38 (76%) eram angiograficamente normais ou tinham coronariopatia obstrutiva leve e 12 (24%) tinham coronariopatia importante. Entre os outros 115 pacientes com teste ergométrico positivo, mas duplo produto < 30.000 mmHg.bpm, 59 (51,3%) eram normais ou com coronariopatia obstrutiva leve, e 56 (48,7%) apresentavam coronariopatia obstrutiva importante (Odds Ratio = 0,3327 IC 95% = 0,1579 a 0,7009; P = 0,0034). CONCLUSÃO: Com base nos dados obtidos dessa investigação, demonstrou-se que o duplo produto elevado constituiu-se em uma variável importante para prever a ausência de coronariopatia obstrutiva significante em indivíduos com teste ergométrico positivo, podendo tornar-se ferramenta útil na tomada de decisão clínica.]]>

“…The test is usually considered nondiagnostic if the patient fails to achieve 85% of the maximum age-predicted heart rate (APHR). The incidence of submaximal stress testing has ranged from 9% (10) to 62% (11) in various studies. Patients on beta-blockers and calcium channel blockers are less likely to achieve target heart rate during stress testing, with a reported incidence of 5% to 40% (9,(12)(13)(14).…”
