[Baroreceptor regulation of blood circulation in healthy persons and in patients with hypertension]. 1990

A A Babaev, and A N Rogoza, and V V Panfilov, and O Iu Atykov

Carotid sinus baroreceptor stimulation by generating subatmospheric pressure in a special neck chamber was used to examine the hemodynamic baroregulation in males divided into 4 groups: (1) healthy subjects; (2) patients with Stages IB to IIA hypertensive disease; (3) those with Stage IIB hypertension; (4) those with malignant hypertension. In Group 2, the patients had a lower ability of carotid baroreflexes to damp elevated systolic pressure whereas in Group 3 there was baroreflex readjustment and effective vasomotor control was increased, which appeared as more pronounced lowering of blood pressure elevations. The patients with malignant hypertension showed a decreased effective baroreflex control of circulation, which might be one of the factors causing that course of the disease.

UI	MeSH Term	Description	Entries
D006973	Hypertension	Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more.

D006974	Hypertension, Malignant	A condition of markedly elevated BLOOD PRESSURE with DIASTOLIC PRESSURE usually greater than 120 mm Hg. Malignant hypertension is characterized by widespread vascular damage, PAPILLEDEMA, retinopathy, HYPERTENSIVE ENCEPHALOPATHY, and renal dysfunction.	Malignant Hypertension

D012018	Reflex	An involuntary movement or exercise of function in a part, excited in response to a stimulus applied to the periphery and transmitted to the brain or spinal cord.

D002346	Carotid Sinus	The dilated portion of the common carotid artery at its bifurcation into external and internal carotids. It contains baroreceptors which, when stimulated, cause slowing of the heart, vasodilatation, and a fall in blood pressure.	Sinus, Carotid
D006439	Hemodynamics	The movement and the forces involved in the movement of the blood through the CARDIOVASCULAR SYSTEM.	Hemodynamic
