Early improvement in left ventricular diastolic function after relief of chronic right ventricular pressure overload.
Chronic right ventricular pressure overload is associated with left ventricular diastolic dysfunction. Whether or not an abrupt reduction in pulmonary artery pressure in patients with chronic pulmonary hypertension results in early improvement of left ventricular diastolic function is unknown. To assess this, the Doppler indexes of left ventricular diastolic function and echocardiographic measu...
متن کاملRegression of pressure overload-induced left ventricular hypertrophy in mice.
As a prelude to investigating the mechanism of regression of pressure overload-induced left ventricular (LV) hypertrophy (LVH), we studied the time course for the development and subsequent regression of LVH as well as accompanying alterations in cardiac function, histology, and gene expression. Mice were subjected to aortic banding for 4 or 8 wk to establish LVH, and regression was initiated b...
متن کاملechocardiographic assessment of inappropriate left ventricular mass and left ventricular hypertrophy in patients with diastolic dysfunction
background: early diagnosis of left ventricular mass (lvm) inappropriateness and left ventricular hypertrophy (lvh) can result in preventing diastolic left ventricular dysfunction and its related morbidity and mortality. this study was performed to determine if diastolic dysfunction is associated with lvh and inappropriate lvm. methods: one hundred and twenty five uncomplicated hypertensi...
متن کاملInterstitial expansion in pressure overload left ventricular hypertrophy
Background Diffuse myocardial fibrosis (DMF) is an important factor in cardiac disease, but until recently could only be accurately assessed with biopsy. We hypothesised that DMF measured by Equilibrium contrast CMR (EQ-CMR) is elevated in cardiac pressure overload (hypertension and aortic stenosis), that the degree of DMF will track the clinical severity of pressure overload and cardiac effect...
متن کاملCardiocyte cytoskeleton in patients with left ventricular pressure overload hypertrophy.
OBJECTIVES We sought to determine whether the cardiocyte microtubule network densification characteristic of animal models of severe pressure overload cardiac hypertrophy occurs in human patients. BACKGROUND In animal models of clinical entities causative of severe right and left ventricular (LV) pressure overload hypertrophy, increased density of the cellular microtubule network, through vis...
