Brief Summary

Ambulatory blood pressure monitoring (ABPM) is a major innovation in the history of hypertension diagnosis. In clinical practice, the most well established indication for using ABPM is to identify patients who have high BP readings in the office but normal readings during usual daily activities outside of this setting or vice versa, and to identify varying 24-h BP profiles. However, in recent years, there has been increasing interest in BP values during sleep, and nocturnal BP is now recognized to be superior to daytime BP in predicting fatal and nonfatal cardiovascular events (stroke, myocardial infarction, and cardiovascular death), especially in medicated patients. The current direction in the management of hypertension is toward earlier and lower BP control for 24 hours, including the nocturnal and morning periods. Therefore, it may be of great significance to pay attention to the management of nocturnal blood pressure so as to reduce the increased cardiovascular risks. Information of nocturnal hypertensive patients defined by ABPM was prospectively registered nationwide, and then to investigate whether there was difference in cardiovascular prognosis according to the control of ambulatory nocturnal blood pressure.

Outcome Measures

Primary Outcomes (1)

  • The occurrence time of fatal and non-fatal cardiovascular events.

    Fatal and non-fatal cardiovascular events, including cardiovascular mortality, non-fatal myocardial infarction, non-fatal stroke, coronary artery bypass grafting or interventional stenting or balloon dilation, and hospitalization for heart failure.

    From date of enrollment until date of first documented event assessed up to 3 years

Secondary Outcomes (2)

  • The occurrence time of all-cause mortality.

    From date of enrollment until date of first documented event, assessed up to 3 years

  • The occurrence time of fatal and nonfatal stroke.

    From date of enrollment until date of first documented event assessed up to 3 years

Study Arms (2)

Nocturnal controlled hypertension

Nocturnal blood pressure was controlled under 120/70 mmHg after aggressive anti-hypertensive therapy.

Nocturnal uncontrolled hypertension

Nocturnal blood pressure was still over 120/70 mmHg after aggressive anti-hypertensive therapy.
