Among the potential targets for improving health and prevention of cardiovascular diseases, hypertension represents one of the most prevalent and potentially modifiable risk factors. Despite its serious risks, hypertension often goes undiagnosed due to its lack of noticeable symptoms, making early detection crucial. In this article, I will explore how the HUAWEI WATCH D2 and HUAWEI WATCH D can help identify early signs of hypertension, offering an effective tool for understanding their blood pressure trends and patterns and consult a healthcare professional accordingly.

Rethinking Hypertension: The Urgent Need to Enhance Detection and Control

HUAWEI WATCH D2 and HUAWEI WATCH D: Certified Health Monitoring

Daily Life Use and Detection of Masked Hypertension

Conclusion

To recognize these potential risks early or to avoid them altogether, it is advisable to measure your blood pressure regularly, even at a young age. But let's be honest—how many of us actually have a blood pressure monitor at home and only use it as precaution? Most people don't think about their blood pressure until there's a problem.

Rethinking Hypertension: The Urgent Need to Enhance Detection and Control

Much concern has been raised by recent guidelines [1-3] on the diagnosis and management of hypertension about the need for a fresh focus on hypertension recognition, and the need to revitalize hypertension control efforts [3]. This is critical because untreated hypertension can lead to severe health issues, such as:
o Coronary artery disease (CAD)
o Heart attack (myocardial infarction)
o Stroke
o Heart failure
o Peripheral artery disease (PAD)
o Aneurysm
o Hypertension-related heart disease
o Kidney diseases

Indeed, in the last years the intensity has relaxed for the identification of new patients with high blood pressure, and for the necessity to maintain blood pressure control during antihypertensive treatment [4]. This is particularly critical because many individuals with high blood pressure do not always experience symptoms. When symptoms do occur, they may include:
o Headaches
o Dizziness
o Difficulty breathing
o Nausea
o Vomiting
o Blurred or altered vision
o Anxiety


To recognize these potential risks early or to avoid them altogether, it is advisable to measure your blood pressure regularly, even at a young age. But let's be honest—how many of us actually have a blood pressure monitor at home and only use it as precaution? Most people don't think about their blood pressure until there's a problem.

HUAWEI WATCH D2 and HUAWEI WATCH D: Certified Health Monitoring

However, the advent of new technologies in smartwatches has opened up new possibilities for measuring blood pressure that go beyond traditional measurements. Devices such as the HUAWEI WATCH D series give us the opportunity to monitor home blood pressure and to test whether these symptoms are associated with excessively elevated or low blood pressure values. Other emerging technologies include wearable, wrist-based blood pressure measurement devices, devices evaluating central blood pressure, and cuffless devices implementing plethysmographic or other technologies.

As studies have shown, the blood pressure readings taken by the HUAWEI WATCH D are not only comparable to those obtained from a reference sphygmomanometer, but are also consistent and accurate when measured against the gold standard clinical sphygmomanometer [5-8]. Moreover, thanks to its dual-use functionality, the HUAWEI WATCH D and its successor, the HUAWEI WATCH D2 can be comfortably worn all day, facilitating long-term monitoring and enabling the detection of both asymptomatic and symptomatic high blood pressure.

The HUAWEI WATCH D combines the functions of an advanced smartwatch with the ability to monitor our health status, including the monitoring of blood pressure, electrocardiogram heart rate, SpO2, stress, and skin temperature.

Notably, it has been validated for use according to international protocols, most notably the CE certification in EU countries [5-8]. The second generation, the HUAWEI WATCH D2, is an evolution of the HUAWEI WATCH D, also a cuff-based blood pressure smartwatch CE medical certification., with the additional feature of ambulatory blood pressure monitoring (ABPM).

The HUAWEI WATCH D2 uses the same technology for blood pressure measurement as the HUAWEI WATCH D, which has been validated for medically certified according to international protocols [6-9]. In fact, the blood pressure values measured by the HUAWEI smartwatch were comparable to the reference blood pressure of a traditional blood pressure monitor by sphygmomanometer [5-8].The measurement is carried out by an integrated miniature pump and an inflatable cuff in the wristband, which precisely measures the blood pressure on the wrist.

a. Monitoring Blood Pressure at Home with HUAWEI WATCH D2 and HUAWEI WATCH D

It is now out of the question that home blood pressure is a highly valuable clinical tool, and its use is constantly growing [9,10]. It is also well-documented that home blood pressure received over the past 2 or 3 decades a greater bulk of data supporting its use to refine the grading of patients into risk levels and, in general, the management of the hypertensive patient [9,10].

Daily Life Use and Detection of Masked Hypertension

I had the opportunity to try this device during usual daily life. The use of this device is very simple, and it shows that individuals may care more about blood pressure monitoring accuracy, with better compliance. Using the HUAWEI Health App, the HUAWEI WATCH D2 and D computes mean blood pressure and mean heart rate, choosing a time span ranging from 1 day to 1 month.

The HUAWEI WATCH D also offers the opportunity to detect masked hypertension [11-14]. Masked hypertension detection involves monitoring blood pressure outside of a clinical setting, often using home blood pressure monitors or wearable devices that track readings throughout the day in various environments. The new function of the HUAWEI WATCH D2 offers continuous measurements (with the option of setting 15-, 20-, 30-, 45- and 60-minute intervals) over 24 hours, including day and night. The user can now set whether the watch measures blood pressure automatically or not. Notably, using its specific app, (HUAWEI Health APP) the HUAWEI WATCH D2 generates specific reports including all these components of ambulatory blood pressure.

Good to know

Masked hypertension is a condition where an individual's blood pressure appears normal during a medical check-up at the doctor's office but becomes elevated at home or in other environments. This discrepancy can often go unnoticed during routine visits, posing a higher risk for cardiovascular diseases. It affects approximately 1 in 7-8 individuals who have normal readings in a clinic or doctor's office.

Meta-analysis [11]of longitudinal studies that addressed the prognostic impact of masked hypertension diagnosed by ambulatory blood pressure and self-measured blood pressure(when compared with normotension)

Most importantly, subjects with masked hypertension show a 1.5x to 3x higher risk of major cardiovascular disease than those with normal blood pressure [11-14]. Several factors have been identified as possible contributors to masked
hypertension:
o Psychological stress
o Physical activity
o Cigarette smoking
o Alcohol
o Work-related stress

The HUAWEI WATCH D2 is recommended for personal use across a wider population and potentially offers opportunities to drive precision medicine

Moreover, the HUAWEI WATCH D2 may be a useful device to detect masked hypertension among subjects who appear to be more likely to have this condition, and encourage users to seek advice from a medical professional. It is now well established that ambulatory blood pressure monitoring (ABPM) can paint the rest of the picture about the real blood pressure load and variability of a person over a 24-hour period. Tillhe ambulatory blood pressure monitoring (ABPM) function of the second generation of the smartwatch offers greater prognostic value than single office readings for doctors, as it provides data which enables me to obtain a more comprehensive assessment of cardiovascular risk [16].

Conclusion:

In conclusion, the HUAWEI WATCH D2 and HUAWEI WATCH D can be recommended for personal use across a wider population [8]. The rich data from blood pressure measurements, along with other health-related parameters recorded by the watch and corresponding app, HUAWEI Health APP, offer greater insight into individual health, and enable healthcare professionals to assist users more adequately in their healthcare journey.
