Key result
Employing two sleep criteria aims to accurately capture blood pressure changes during sleep to detect morning surge, addressing the limitations of standard 24-hour ambulatory monitoring.
Why the study?
Morning surge is linked to cardiovascular diseases, but standard 24-hour ABPM cannot automatically distinguish awakening from sleep, requiring clearer sleep separation.
The paper proposes a method using two sleep criteria to more accurately detect blood pressure morning surge compared to standard ABPM.

Dual sleep criteria may sharpen morning surge identification in practice; extends ABPM methodology for hypertension trials.
This paper aims to analyze the blood pressure transition during sleep. Morning surge is a sudden increase in blood pressure from awakening or before awakening. Morning surge is implicated in cardiovascular diseases, such as Stroke, Angina Pectoris, and Myocardial Infarction. Morning surge has been detected mainly by the ABPM (Ambulatory Blood Pressure Monitoring) method, which measures blood pressure for 24-hours. Since the ABPM method cannot distinguish awakening and sleep automatically, their alternative method is forcibly delimiting time or manually processing based on behaviour records. Therefore, it is necessary to capture the blood pressure change under clear sleep separation. This paper employs two sleep criteria for accurate blood pressure during sleep.

Takahashi et al. (2020) studied Morning blood pressure surge. Two sleep criteria vs. Standard Ambulatory Blood Pressure Monitoring (ABPM) was evaluated on Blood pressure transition during sleep. Employing two sleep criteria aims to accurately capture blood pressure changes during sleep to detect morning surge, addressing the limitations of standard 24-hour ambulatory monitoring.
