This study assessed the clinical or echographic factors predisposing to dynamic left ventricular obstruction (LVO) during dobutamine echocardiography (DE) in patients with angina-like chest pain but without coronary artery disease (CAD). DE is an effective technique for the noninvasive diagnosis of underlying CAD. During DE, an LVO is not unusual in ischemic patients.
Normal coronary angiogram and dobutamine-induced left ventricular obstruction during stress echocardiography: a higher hemodynamic responsiveness to dobutamine.
