Blood Pressure

High blood pressure at night is more dangerous than previously thought!

According to a new technique developed by UCL scientists, blood pressure measured near the heart is substantially greater during sleep than previously assumed. So read on this article about high blood pressure at night that healthowealth has prepared for you!

What exactly is high blood pressure at night?

Blood pressure at night is a significant predictor of stroke and heart disease, with earlier studies indicating that blood pressure is measured via arm drops at night when sleeping. However, a recent study suggests that the night-time blood pressure drop may be less important than previously anticipated.

The findings, published in the journal Hypertension, have substantial implications for the evaluation of future treatments since medications used to treat high blood pressure at night can have vastly different effects on the pressure around the heart when compared to the traditional arm approach.

The researchers collaborated with a Singaporean technology company to create a portable wristwatch-based device with a sensor in the strap that detects the pulse wave at the wrist rather than directly computing the pressure.

The team was able to properly compute pressure at the aortic root (near the heart) for a whole 24 hours without upsetting the persons being monitored by mathematically modeling the pulse wave.

Dangerous side effects of high blood pressure at night

“High blood pressure at night is a key risk factor in the development of cardiovascular disease,” explains lead author Professor Bryan Williams, who is also the Director of the NIHR University College London Hospitals Biomedical Research Centre (heart attack, stroke).

It affects approximately 12 million individuals in the United Kingdom and is the leading avoidable cause of death.

This is the first research to describe the normal change in blood pressure during the day and night using measurements collected near the heart. We discovered that high blood pressure at night does not drop as much during sleep as previously anticipated based on traditional pressure measures obtained from the arm.

The authors anticipate that their findings highlight the importance of lowering blood pressure during night, potentially altering techniques to treat and detect high blood pressure at night.

Previous study reveals that a lack of sleep is linked to elevated blood pressure. When sleep habits are disrupted, the chance of having high blood pressure at night rises.

Prof. Williams and colleagues discovered that by calculating the trends of brachial blood pressure (in the arm) and central aortic pressures (where blood exits the heart) at the same time, there was a significantly lower night-time drop in central aortic pressure relative to the corresponding night-time drop in brachial pressure, despite similar circadian rhythms.

The findings show that aortic pressures at night are disproportionately larger than brachial pressures during sleep. This might be useful information for physicians looking into the detrimental effects of high blood pressure at night on the heart and brain.
