Left Ventricular Chamber and Myocardial Systolic Function Reserve in Patients with Type 1 Diabetes Mellitus: Insight from Traditional and Doppler Tissue Imaging Echocardiography

LV longitudinal systolic function (DTI) parameters did not fall into the paradigm of the stress-shortening relationship used to describe LV contractility. However, both LV circumferential contractility and longitudinal systolic function reserves correlated with stroke index reserve during LDD.
