Orthostatic hypertension: the last hemodynamic frontier.
Orthostatic hypertension (OHT) is beneath the radar of many health care professionals. In the clinic, it is generally both unexpected and counterintuitive. After recheck, it may sometimes regress toward the mean. However, at other times the OHT can be dramatic and persistent. Nevertheless, our knowledge about its causes and significance remains circumscribed. It is in many ways the last hemodyn...
متن کاملPersistent hemodynamic changes in ruptured brain arteriovenous malformations.
BACKGROUND AND PURPOSE Hemodynamic properties of brain arteriovenous malformations (AVMs) with risk factors for a future hemorrhage are essentially unknown. We hypothesized that AVMs with anatomic properties, which are associated with an increased rupture risk, exhibit different hemodynamic characteristics than those without these properties. METHODS Seventy-two consecutive patients with AVMs...
متن کاملMicroembolism and hemodynamic changes in the brain during carotid endarterectomy.
Response Dr Jolobe's report of an 85-year-old woman with a history of stroke, primary hypothyroidism, and low gonadotropin levels appears to conform to the findings we described in a study of postmenopausal women with stroke. The presence of primary hypothyroidism in his patient is in contrast to findings in our group, in which thyroid function was normal. The fact that hypogonadotropic hypogon...
متن کاملAntihypertensive therapy and orthostatic hemodynamic responses in acute stroke.
BACKGROUND It is not known whether antihypertensive medications affect orthostatic blood pressure (BP) regulation in the early period after stroke. Knowledge of this may have implications for clinical practice. METHODS A total of 40 acute ischemic stroke patients (mild-to-moderate severity) taking antihypertensive drugs, and 40 patients with acute stroke of similar severity not receiving such...
متن کاملHemodynamic changes in hypertension.
DESPITE a vast amount of work devoted to the subject the nature of the fundamental hemodynamic changes in chronic, human hypertension is poorly understood. In this necessarily brief discussion the main outlines of the problem will be sketched in emphasizing the respective roles of the heart, large arteries and resistance vessels. Other factors such as the sympathetic nervous system, the barorec...
