Registry Study on "Control Nocturnal Hypertension to Reach the Target "
An observational study of Nocturnal Hypertension, run by Shanghai Institute of Hypertension at 1 site in China.
Trial 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… Read more about this study

About this study
Official title: Registry Study on "Control Nocturnal Hypertension to Reach the Target "（CONTROL-NHT）
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| 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. |
What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: 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.
Measured: From date of enrollment until date of first documented event, assessed up to 3 years
The occurrence time of fatal and nonfatal stroke.
Measured: From date of enrollment until date of first documented event assessed up to 3 years
