“…Eine Alternative zur DASE ist das erst seit wenigen Jahren verfügbare Arbutamin, ein synthetisches Katecholamin mit in etwa 10fach größerer Affinität zu ß-Rezeptoren und deutlich milderer Affinität zu α-Rezeptoren als Dobutamin (11). Die ß-stimulierenden Eigenschaften sind ausgeglichener als beim Dobutamin, so daß bei vergleichbarer inotroper Stimulation ein stärkerer Frequenzanstieg resultiert.…”

The presented case report describes lifethreatening complications of pharmacological stress echocardiography with dobutamine. A 66-year old male suffered an acute anterior wall myocardial infarction during dobutamine atropine stress echocardiography. Symptoms and signs of myocardial infarction developed after maximal dobutamine-dose (40 micrograms/kg/min) and the additional application of atropine. Emergency coronary angiography revealed extensive coronary artery disease with proximal occlusion of the left anterior descending artery which was successfully recanalized. In a second patient ventricular fibrillation echocardiography and electrocardiographic signs of acute myocardial ischemia developed after high-dose dobutamine stress and required prolonged resuscitation. The possible mechanisms, incidence and risk of acute myocardial ischemia during dobutamine-atropine stress are discussed and compared to bicycle ergometry. The presented life threatening complications of dobutamine-atropine stressechocardiography emphasize the important of available and adequate emergency facilities.
