Right 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 کاملAbnormal left ventricular diastolic filling in chronic thromboembolic pulmonary hypertension: true diastolic dysfunction or left ventricular underfilling?
OBJECTIVES The purpose of this study was to investigate the cause of abnormal left ventricular (LV) Doppler diastolic filling characteristics in chronic thromboembolic pulmonary hypertension (CTEPH). BACKGROUND In CTEPH, LV diastolic function often appears abnormal. It is unclear whether this "impaired relaxation" (E<A) filling pattern is caused by septal hypertrophy, right ventricular (RV) e...
متن کاملright ventricular strain and strain rate in patients with systemic sclerosis without pulmonary hypertension
conclusions this study indicated that the rv systolic strain and strain rate can be used to detect early rv systolic dysfunction in ssc patients without pulmonary hypertension. these parameters may be useful for the provision of a more adequate management of ssc patients. results in the ssc patients, the rv strain (- 19 ± 10 vs. - 25 ± 4 %; p = 0.004) and the systolic strain rate (- 1.3 ± 0.5 v...
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 کاملEchocardiographic evaluation of left-ventricular diastolic function in patients with chronic pulmonary hypertension.
Different patterns of left-ventricular (LV) diastolic dysfunction were reported in patients with pulmonary hypertension (PHT). There are no data regarding the relationship between the severity of PHT and LV diastolic dysfunction. In order to determine the severity of PHT at which LV diastolic dysfunction occurs and to identify its pattern, we studied by Doppler echocardiography 120 patients wit...
