Hemodynamics in Labile Hypertension
a high cardiac output and a lower than normal total peripheral resistance. It was our feeling, based on this original work, that this pattern might be an early phase or a benign type of essential hypertension. This is a report of the first follow-up study done on a group of such labile hypertensive patients in whom the hemodynamics and clinical status have been studied over a period of 50 month...
متن کاملLabile Hypertension: A Faulty Concept?
Labile blood pressure elevation is believed to have less clinical significance than "fixed hypertension." This assertion was examined in the Framingham cohort of 5209 men and women followed for 20 years for the development of cardiovascular events in relation to three routinely measured blood pressures at each of 10 biennial examinations. Variability of pressure judged from the standard deviati...
متن کاملLabile hypertension and jogging: new diagnostic tool or spurious discovery?
A labile hypertensive black man reviews his own personal history of hypertension, based on intensive self-study. The evidence suggests that aerobic isotonic exercise (jogging) depresses labile pressure values, forcing them down to near basal levels and preventing a rise to previous blood pressure levels for several hours.
متن کاملChronic labile hypertension produced by lesions of the nucleus tractus solitarii in the cat.
Bilateral electrolytic lesions of the nucleus tractus solitarii (NTS) were made at the level of the obex in seven cats. Within 1 hour the mean arterial pressure (MAP) rose to a maximum of 144 mm Hg (141% of control), and by 7 hours heart rate reached a peak of 236 beats/min (148% of control). The baroreceptor reflexes were abolished. After 24 hours the arterial pressure became extremely labile,...
متن کاملCirculating catecholamines and systolic time intervals in labile and sustained hypertension.
1. Average supine circulating total catecholamine concentrations were found to be higher than the normal range in about 50% of patients with labile hypertension and in about 30% of patients with sustained essential hypertension. 2. These higher resting concentrations were mainly due to an increase in adrenaline in labile hypertension and to an increase in noradrenaline in sustained hypertension...
