We present assessment of chest pain patients by multiparametric dobutamine stress echocardiography to differentiate inducible ischemia with obstructive coronary artery disease and with no obstructive coronary artery disease. In addition to the classical regional wall motion abnormality, we illustrate how coronary flow velocity reserve by Doppler echocardiography assists diagnosing coronary microvascular dysfunction.
