Purpose -This study focuses on the safety and hemodynamic effects of dobutamine stress echocardiography.Methods -Seven hundred and thirty five consecutive patients underwent dobutamine stress echocardiography for the evaluation of coronary artery disease and or cardiomyopathy. Dobutamine was administered intravenously at incremental doses of 5, 10, 20, 30µg/kg/min, at 3min intervals
Sintomas, Complicações e Alterações Hemodinâmicas Associadas a Ecocardiografia de Estresse com Dobutamina Artigo OriginalDobutamina é uma amina simpaticomimética sintética que possui propriedades adrenérgicas alfa-1, beta-1 e beta-2 1 . Com as doses terapêuticas habitualmente empregadas, os receptores beta-1 são primariamente estimulados, provocando resposta inotrópica maior do que a cronotrópica.
