Samsung presents the results of recent research published by the prestigious medical journal Frontiers in Neurology. According to this study, measuring blood pressure on a watch can range Galaxy Watch to help patients with Parkinson's disease effectively manage so-called orthostatic hypotension, i.e. acute conditions of low pressure caused by insufficient contraction of blood vessels.
Orthostatic hypotension is common in patients with Parkinson's disease and increases the risk of falling in the elderly who also suffer from cardiovascular problems. Frequent blood pressure measurements can reveal significant pressure deviations and thus contribute to the diagnosis and management of Parkinson's disease. Samsung Smart Watch Galaxy Watch 3, Galaxy Watch Active 2 and the latest models Galaxy Watch 4 to Galaxy Watch 4 Classic they have sophisticated sensors that monitor blood pressure using pulse wave analysis (physical data is captured by built-in heart activity sensors). Users can continuously monitor blood pressure and other important data in the Samsung Health Monitor app and share it during consultations with doctors and health professionals in PDF format.
The Samsung Medical Center research team led by dr. Jin Whan Choa and Dr. Jong Hyeon Ahna compared blood pressure measurements from watches Galaxy Watch 3 with the values measured by the tonometer and evaluated their accuracy. According to this study, they allow Galaxy Watch 3 easy, fast and reliable blood pressure measurement and will alert you to deviations, at the same time they are significantly more practical and comfortable than ordinary tonometers.

The research was carried out in a group of 56 patients with an average age of 66,9 years. On one arm it was measured with a tonometer, on the other with a watch Galaxy Watch 3. The researchers measured the blood pressure of each patient three times. It has been shown that measuring blood pressure using Galaxy Watch 3 and the tonometer gives comparable results. The mean and standard deviation were 0,4 ± 4,6 mmHg for systolic pressure and 1,1 ± 4,5 mmHg for diastolic pressure. The correlation coefficient (r) between the two devices reached 0,967 for systolic and 0,916 for diastolic pressure.
"Orthostatic hypotension is a common but serious manifestation that has a great impact on the situation of patients with Parkinson's disease. However, it is difficult to diagnose just by observing the symptoms and it can escape attention even during a routine blood pressure measurement. If we had a smart watch and could use it to measure patients' blood pressure regularly, many existential problems could be detected at an early stage. This would be a major advantage in the treatment and management of Parkinson's disease," the research team said.
The study carried out by the team of dr. Choa and Dr. Ahna published in its latest issue the prestigious medical journal Frontiers in Neurology under the title Validation of Blood Pressure Measurement Using a Smartwatch in Patients with Parkinson's Disease.
Blood pressure measurement is currently provided by the Samsung Health Monitor application, which is also available in the Czech Republic.
