Sleep induces similar hemodynamic changes driven by diminished peripheral resistance in normal and hypertensive subjects, though hypertensives maintain decreased baroreflex sensitivity.
How do haemodynamic parameters change during sleep in normal and hypertensive subjects?
The fall in blood pressure during sleep is driven by diminished peripheral resistance, with similar haemodynamic changes in normal and hypertensive subjects, though hypertensives have decreased baroreflex sensitivity.
Absolute Event Rate: 0% vs 0%
The fall of blood pressure accompanying sleep in man is largely due to a diminished peripheral resistance. Subjects with normal and raised arterial pressure show qualitatively and quantitatively similar haemodynamic changes during sleep, except that the baroreflex sensitivity in hypertensives is decreased, both awake and asleep.
Bristow et al. (Wed,) reported a other. Sleep induces similar hemodynamic changes driven by diminished peripheral resistance in normal and hypertensive subjects, though hypertensives maintain decreased baroreflex sensitivity.
