Arterial hemodynamics in human hypertension.
Differences in aortic impedance between normotensives and hypertensives are not well characterized. We examined impedance in 8 normotensive and 11 hypertensive (mean 96.7 vs. 122.2 mmHg) age-matched, Chinese patients undergoing cardiac catheterization at rest, during nitroprusside, and handgrip exercise before and after beta blockade (propranolol). Hypertensives had higher resistance (2,295 vs....
متن کاملSex and Hemodynamics in Pulmonary Arterial Hypertension
Introduction: Female sex is a risk factor for pulmonary arterial hypertension (PAH), yet women have better survival than men. We sought to determine if sex was associated with baseline hemodynamics in subjects with PAH, and whether age modified these relationships. Material and Methods: We conducted a pooled analysis from 11 randomized trials submitted to the U.S. Food and Drug Administration. ...
متن کاملArterial stiffness, central hemodynamics, and cardiovascular risk in hypertension
This review summarizes several scientific contributions at the recent Satellite Symposium of the European Society of Hypertension, held in Milan, Italy. Arterial stiffening and its hemodynamic consequences can be easily and reliably measured using a range of noninvasive techniques. However, like blood pressure (BP) measurements, arterial stiffness should be measured carefully under standardized...
متن کاملAre hemodynamics surrogate end points in pulmonary arterial hypertension?
BACKGROUND Although frequently assessed in trials and clinical practice, hemodynamic response to therapy has never been validated as a surrogate end point for clinical events in pulmonary arterial hypertension (PAH). METHODS AND RESULTS We performed a patient-level pooled analysis of 4 randomized, placebo-controlled trials to determine whether treatment-induced changes in hemodynamic values a...
متن کاملAngiotensin II, mechanotransduction, and pulsatile arterial hemodynamics in hypertension.
The aortic blood pressure curve involves two components: a steady component, the mean arterial pressure (MAP), which is dependent on cardiac output and vascular resistance, and a pulsatile component pulse pressure (PP), which is dependent on arterial stiffness and pulse wave reflections. The transduction mechanisms of MAP and PP differ markedly, involving focal adhesion kinase for MAP and oxyge...
