Abstract Background: Normal coronary flow velocity reserve (CFVR) (≥ 2) obtained in the left anterior descending coronary artery (LAD) from transthoracic echocardiography is associated with a good prognosis, but there is no study correlating CFVR with submaximal target heart rate (HR). Objective: To evaluate the prognostic value of CFVR obtained in the LAD of patients with preserved (>50%) left ventricular ejec...

Fundamento: A reserva de velocidade de fluxo coronariano (RVFC) ≥ 2 é adequada para inferir bom prognóstico ou ausência de coronariopatia importante. Objetivo: Identificar parâmetros relevantes na obtenção da RVFC (adequada ou inadequada) na descendente anterior (ADA), durante o ecocardiograma sob estresse com dobutamina (EED). Métodos: Avaliação de 100 pacientes encaminhados para pesquisa de isquemia miocárdic...
