The obligatory role of the kidney in long-term arterial blood pressure control: extending Guyton's model of the circulation.

30 Oct 2009 We describe a model for the essential role of the kidney in long-term blood pressure regulation. We begin with a simple hydraulic model for the circulation, with a constant circulating volume. We show, with the help of a modification of Guyton's ... Read more...

When drugs disappear from the patient: elimination of intravenous medication by hemodiafiltration.

30 Oct 2009 Twenty-three hours after heart transplantation, life-threatening acute right heart failure was diagnosed in a patient requiring continuous venovenous hemodiafiltration (CVVHDF). Increasing doses of catecholamines, sedatives, and muscle relaxants ... Read more...

Mitral E wave deceleration time to peak E velocity ratio and cardiovascular outcome in hypertensive patients during antihypertensive treatment (from the LIFE echo-substudy).

13 Oct 2009 The early mitral flow deceleration time (DTE) is a prognostically validated marker of left ventricular diastolic dysfunction. It has been reported that the DTE is influenced by the loading conditions, which can vary during antihypertensive ... Read more...

Technical information about 'Hypertension'

Definition: 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.

Descriptor UI: D006973

Alternative terms: Hypertension; Blood Pressure, High; Blood Pressures, High; High Blood Pressure; High Blood Pressures;
