BACKGROUND Inadequate sleep may aggravate hypertension, but the pathophysiology of sleep disturbance in hypertension remains unknown. Among spontaneously hypertensive rats (SHR), sleep disturbance co-occurred with sympathetic hyperactivity; therefore, we hypothesized that the sleep disturbance can be alleviated by antagonizing the adrenergic overdrive. METHODS Polysomnographic recording was p...

The research goals were to (1) assess their sleep problems as well as their PTSD, ...
