RESUMO
Comparamos a acurácia entre a ecocardiografia de perfusão miocárdica em tempo real (EPMTR) pela adenosina e pela dobutamina para o diagnóstico de doença arterial coronariana (DAC) em 54 pacientes submetidos a cineangiocoronariografia. Quantificamos a reserva da velocidade (reserva ß) e do fluxo sangüíneo miocárdico (RFM) obtendo uma acurácia diagnóstica para a EPMTR pela adenosina e pela dobutamina com a reserva ß e com a RFM de 76 por cento versus 80 por cento e 65 por cento versus 78 port cento, respectivamente. Portanto, a EPMTR pela dobutamina demonstrou apresentar uma acurácia superior a EPMTR pela adenosina para o diagnóstico / We compared the diagnostic accuracy between myocardial blood flow cardial contrast echocardiography (RTMCE) and dobutamine stress RTMCE for the diagnosis of coronary artery disease (CAD) in 54 patients. Quantitative coronary angiography was performed in all patients. The diagnostic accuracy for CAD of ß reserve using adenosine and dobutamine stress RTMCE were 76 per cent versus 80per cebt, and for MBF reserve were 65 per cent versus 78 per cent, respectively. Therefore, dobutamine stress RTMCE is more accurate for the detection of CAD than adenosine stress RTMCE...
