Acurácia diagnóstica da ecocardiografia com estresse pela dobutamina associada à atropina / Diagnostic Accuracy of Dobutamine-Atropine Stress Echocardiograp

PURPOSE: To analyze the diagnostic accuracy of dobutamine-atropine stress echocardiography. METHODS: We studied 304 consecutive patients using dobutamine-atropine stress echocardiography who underwent coronary angiography within a month of the exam. Patients received high dobutamine doses associated or not with atropine. RESULTS: The global sensitivity was 92, specificity was 72and diagnostic accuracy was 87. Analyzing 120 patients with normal LV function, we found sensitivity of 85, specificity of 79and accuracy of 82. CONCLUSION: Dobutamine-atropine stress echocardiography is an accurate method for the detection of coronary artery disease.
