Perfusion-contraction mismatch during inotropic stimulation in hibernating myocardium
The aims of this study were to assess the value of dobutamine echocardiography in identifying myocardial hibernation versus stunning and to elucidate the underlying pathophysiological mechanism of the contractile impairment. Methods: Twenty-one patients with isolated stenosis of the left anterior
