Left ventricular-arterial coupling relations in the normal human heart.
This investigation was undertaken to assess left ventricular-arterial coupling relations in the normal human heart under varying loading conditions and inotropic states and thereby to establish whether the working point of the normal human heart is at optimal output or mechanical efficiency under basal hemodynamic conditions. In 22 patients with an atypical chest pain syndrome who had normal co...

متن کاملLeft ventricular performance in patients with left ventricular hypertrophy caused by systemic arterial hypertension.
To assess the adaptation of the left ventricle to a chronic pressure overload we used echocardiography to study 18 patients with left ventricular hypertrophy caused by systemic arterial hypertension. Increased values for either posterior wall or interventricular septal thickness or both confirmed the presence of left ventricular hypertrophy in all patients and an increase in the average wall th...
متن کاملThe effect of resistance training on PI3K/mTORc1 signaling in left ventricular of diabetes rats
Background: Clinical evidence points to the effective role of genetic factors and intracellular signaling pathways in physiological cardiac hypertrophy. This study aimed to assess the response of PI3K/mTORc1 signaling pathway in cardiac tissue to resistance training in obese diabetic rats. Materials and Methods: For this purpose, 21 male wistar rats (220±20 g) were obese by 6 weeks high fat di...
متن کاملAssessment of left atrial-left ventricular-arterial coupling using 2-dimensional speckle tracking echocardiography.
by 2D-STE, and investigated the effect of cardiovascular risk factors on LA-LV-arterial coupling.1 In their multivariate linear regression analysis, peak early diastolic LV longitudinal strain rate (SR-LVe) and E/e’/S-LAs were independent predictors related to abdominal aortic stiffness in patients with cardiovascular risk factors. On the other hand, only age contributed to abdominal aortic sti...
