Poor sleep quality, stress status, and sympathetic nervous system activation in nondipping hypertension.

摘要

We have read with great interest the recently published manuscript of Huang et al. [1] related to the sleep quality, stress status, and sympathetic nervous system activation in nondipper hypertensive patients. In this recent study, the authors have demonstrated that nondippers had poorer sleep quality and more stressful status with an increased activity of sympathetic nervous system. A decline of less than 10% blood pressure during night is known as a nondipping blood pressure pattern [2]. It has been estimated that 25% of essential hypertensive patients are nondippers [3]; however, nondipping blood pressure is associated with target organ damage and poorer cardiovascular outcomes [4].
