Right ventricular performance in essential hypertension.
Effects of systemic hypertension on right ventricular (RV) performance have not been previously investigated. In this study, 10 normal patients were compared to 20 patients with uncomplicated, asymptomatic essential hypertension (defined as cuff diastolic blood pressure 2 100 mm Hg) after a complete hemodynamic and RV cineangiographic evaluation. The mean intra-arterial pressure in the normal g...
متن کاملThe influence of Asthma on Right Ventricular Systolic and Diastolic Function in Children according to Tissue Doppler Echocardiography
Introduction:Asthma is the most common chronic inflammatory condition affecting the lower airways among children. Asthma may influence right ventricular (RV) function and patients may develop right ventricular hypertrophy, pulmonary hypertension and cor pulmonale. The main objective of this study is to determine RV dysfunction in asymptomatic asthmatic children as detected by ti...
متن کاملClinical relevance of right ventricular diastolic stiffness in pulmonary hypertension.
Right ventricular (RV) diastolic stiffness is increased in pulmonary arterial hypertension (PAH) patients. We investigated whether RV diastolic stiffness is associated with clinical progression and assessed the contribution of RV wall thickness to RV systolic and diastolic stiffness. Using single-beat pressure-volume analyses, we determined RV end-systolic elastance (Ees), arterial elastance (E...
متن کاملRight ventricular diastolic impairment in patients with pulmonary arterial hypertension.
BACKGROUND The role of right ventricular (RV) diastolic stiffness in pulmonary arterial hypertension (PAH) is not well established. Therefore, we investigated the presence and possible underlying mechanisms of RV diastolic stiffness in PAH patients. METHODS AND RESULTS Single-beat RV pressure-volume analyses were performed in 21 PAH patients and 7 control subjects to study RV diastolic stiffn...
متن کاملPrognostic significance of left ventricular diastolic dysfunction in essential hypertension.
OBJECTIVES We sought to assess the prognostic value of alterations in left ventricular (LV) diastolic function in patients with essential hypertension. BACKGROUND Alterations in LV diastolic function are frequent in patients with hypertension, even in the absence of LV hypertrophy, but their prognostic significance has never been investigated. METHODS In the setting of the Progetto Ipertens...
