Ecocardiografia de estresse por dobutamina / Stress echocardiography for dobutamine

RESUMO

To avoid systematic coronary angiography to diagnose ischemic heart disease, a variety ofg stress test are available for the detection of coronary artery disease in patients who are unableto undergo dynamic exercice testing. Dobutamine stress test is very sage and sensitive in detecting obstruction in coronary circulation. Besides it can recognize viable myocardium in patients exhibiting prolonged contractile disfunction. The data support the notion that stress echocardiography has evolved as a useful imaging tool for the diagnose of early coronary artery disease
