[A preliminary study on parietal stress decay in patients with left ventricular hypertrophy (author's transl)].

In order to determine equatorial and radial stresses at various depths of left ventricular wall, left ventricular pressures and echocardiographic dimensions were elaborated using the formula proposed by Timoshenko. Patients with concentric left ventricular hypertrophy (LVH) have minor end-diastolic and end-systolic decay of radial and equatorial stresses, compared to patients with eccentric LVH. The total stress affecting left ventricular wall is significantly minor in telediastole than in telesystole.
