Análise da Segurança e Exequibilidade do Ecocardiograma sob Estresse com Dobutamina em Dez Mil e Seis Exames de uma População Geral

Abstract: Fundamento: Durante o ecocardiograma sob estresse com dobutamina, podem ocorrer efeitos adversos e exames inconclusivos. Objetivo: Avaliar em uma grande população geral a segurança e a exequibilidade do ecocardiograma sob estresse com dobutamina. Métodos: Estudo de 10.006 ecocardiogramas sob estresse com dobutamina realizados no período de julho de 1996 a setembro de 2007. A dobutamina foi administrada em quatro estágios (10, 20, 30 e 40 μcg.kg-1.min-1) para pesquisa de isquemia miocárdica e iniciada com 5 μcg… Show more

“…At this point, the test was concluded and a bolus of 3 mg of esmolol was administered intravenously and later repeated to return the HR to baseline levels. 1,2 ADA flow was checked intermittently to reach a diastolic velocity twice as high as that at baseline to determine a normal CFVR (≥2). [3][4][5] It should be noted that this normal coronary reserve was obtained early (HR = 98 bpm), i.e., at only 61% of the maximum test HR (Figure 3B).…”

“…In this context, a safe noninvasive assessment such as dobutamine stress echocardiography (DSE) associated with the analysis of coronary flow velocity reserve (CFVR) may be an option for this dilemma between myocardial ischemia and the possible post-infarction ischemic memory. [1][2][3]…”
