Abstract Background Dobutamine stress echocardiography (DSE) using the conventional protocol (CP-DSE) may lead to important adverse effects. Objective This study was aimed at assessing the safety of DSE using a modified protocol (MP-DSE). Methods Data were collected from our institutional database to compare MP-DSE with the CP-DSE. In the CP-DSE, atropine could be administered during the fourth stage or its extension. In the MP-DSE, atropine was initiated at the beginning of the third stage, and there was no stage extension.

After approximately 2 decades of use in practice, based also on several clinical studies, it can be stated that ultrasound enhancing agents (UEA) are extremely safe, following recommendations for their preparation and administration.– Severe adverse events are very rare, with an approximate prevalence of around 1 in every 10,000 administrations, anaphylactoid reactions being the most frequent.,- Specifically with the contrast SonoVue® (sulfur hexafluoride) used in Brazil, Furtado, Rassi, et al., in their safety study, reported a very low incidence of […]

Abstract Background Dobutamine-atropine stress echocardiography (DASE) is an accessible and important test, especially in patients under investigation for coronary artery disease. However, it is necessary to evaluate its safety, as it is used in patients with increasingly complex and serious conditions and in seniors. Objective To confirm the safety of DASE and evaluate the predictors of arrhythmias in a non-hospital setting. Methods DASE was performed to evaluate ischemia using the standard protocol of dobutamine infusion of 5 to 40 mcg/kg/min […]
