Brief Summary

Hypertension is one of the main risk factors for the onset of cardiovascular diseases. It is often silent, and most individuals are unaware they have it. The 24-hour Ambulatory Blood Pressure Monitoring (24-hour ABPM) device allows for continuous blood pressure monitoring over a 24-hour period and is currently considered the gold standard for diagnosing hypertension. However, it is expensive, time-consuming for healthcare personnel, bulky, and often uncomfortable to wear-especially during the night. Recently, other blood pressure monitoring devices have entered the market. One of them is the Aktiia bracelet, renamed as Hilo band as of 8 april 2025, (Hilo band SA, Neuchâtel, Switzerland), CE-marked, which estimates blood pressure and heart rate using a pulse wave analysis (PWA) technique. Hilo band is non-invasive, comfortable to wear, and allows for long-term blood pressure monitoring. However, there is insufficient data to support the use of Hilo band in healthcare settings for the diagnosis and monitoring of hypertension. In one study, Hilo band was compared to the 24-hour ABPM only for daytime blood pressure readings in a population enrolled in a cardiac rehabilitation program, and thus was not tested in apparently 'healthy' individuals who may be hypertensive. Another study assessed Hilo band's performance compared to double auscultation in older adults aged 65 to 85 years in different body positions (sitting, standing, and lying down), and therefore did not include a younger population. In our research project, we aim to evaluate the performance of Hilo band compared to 24-hour ABPM in a younger population, considering both daytime and nighttime blood pressure measurements.

Outcome Measures

Primary Outcomes (1)

  • Evaluate the 24-hour performance of Hilo band in measuring diastolic and systolic blood pressure values in young subjects of 21-35 years of age. We will use the 24h ABPM as a reference method

    To assess our primary endpoint, the 24-hour systolic and diastolic pressure averages (including waking and sleeping hours) of Hilo band will be compared to the 24-hour systolic and diastolic pressure averages of the 24-h ABPM, respectively. A similar performance of the two devices is defined as a standard deviation from the 24-hour (including waking and/or sleeping hours) average systolic and/or diastolic pressure values of maximum 10 mmHg, as reported in previous studies. We will consider valid and include in the analysis 24-h ABPM recordings lasting ≥22 hours with ≥80% of successful readings, and cumulative recording gaps no greater than 2 hours. On the other hand, Hilo band's blood pressure recordings are considered valid if at least 24 measurements are recorded during the 24 hours period.

    24 hours

Secondary Outcomes (3)

  • Assessing the consistency of the performance of Hilo band in measuring systolic and diastolic blood pressure values in young subject of 21-35 years of age over a 3-day period with the 24-h ABPM as a reference method

    3 days

  • Evaluate the performance of Hilo band in effectively classifying hypertension in young subjects of 21-35 years of age with the 24-h ABPM as a reference method.

    3 days

  • Evaluate the degree of satisfaction of the use of the Hilo band by study participants and physicians with the 24-h ABPM as a reference method.

Study Population

This is a single-centre non-interventional performance research project investigating the performance of Hilo band in two different study populations: population 1 and population 2. In population 1, we will recruit young participants between 21 and 35 years of age that come to our San Giovanni Hospital in Bellinzona with indication to receive a 24-hour BPM. On the other hand, in population 2, we will recruit healthy, voluntary individuals between 21 and 35 years of age.

You may qualify if:

  • Population 2:
  • Informed Consent signed by the subject
  • years of age
  • Functional internet phone connection
  • Negative pregnancy test, ongoing anti-conceptive treatment or declaration of the subject not being pregnant
  • Population 1:
  • Informed Consent signed by the subject
  • years of age
  • Clinical indication for receiving a 24-hour blood pressure measurement
  • Functional internet phone connection
  • Negative pregnancy test, ongoing anti-conceptive treatment or declaration of the subject not being pregnant

You may not qualify if:

  • Allergies to silicone
  • Atrial fibrillation
  • Subjects with arrhythmia
  • Patients suffering from pathologies that systematically reduce peripheral perfusion including Raynaud's disease, diabetes, renal dysfunctions (eGFR \< 30mL / min / 1.73 m2), untreated hyper-/ hypothyroidism, pheochromocytoma, or arteriovenous fistula
  • Interarm Systolic Blood Pressure (SBP) difference over 10% or Diastolic Blood Pressure (DBP) difference over 10%
  • Arm paralysis
  • Amputated upper limb
  • Arm trembling or shivering
  • Upper arm circumference \> 64 cm
