Relation of left ventricular longitudinal and circumferential shortening to ejection fraction in the presence or in the absence of mild hypertension
Diabetes Mellitus, Type 2
Hypertrophy, Left Ventricular
Left ventricular ejection is produced principally by circumferential shortening and is related independently to the relative wall thickness. In the presence of arterial hypertension and an altered cardiac load, longitudinal shortening becomes an important mechanism by which to augment ejection, thereby offsetting the reduction in midwall shortening.
