Determination of digital biomarkers of disease progression for digital phenotyping of patients with arterial hypertension.

Background: To compare the effectiveness of digital phenotyping of patients diagnosed with arterial hypertension with traditional monitoring methods over a three-year period. Patients and methods: The study was conducted from January 2021 to January 2024 among 800 patients diagnosed with arterial hypertension at 6 clinics in Moscow, Russia, evenly divided into experimental (identification of digital biomarkers of disease progression for digital phenotyping) and control (standard monitoring methods) groups. The intervention included lifestyle changes focused on increasing physical activity, improving sleep quality, reducing stress, and modifying diet. Significant improvements were observed in the experimental group compared to the control group. Systolic blood pressure decreased by 10 mmHg (p<0.001), pulse by 5 beats per minute (p<0.001), and stress level by 2 points (p<0.001) in the experimental group. Additionally, physical activity increased by 15 minutes per day (p<0.001), and sleep quality improved by 2 points on a scale from 1 to 10 (p<0.001). Results: Multiple regression analysis showed a decrease in the significance of digital biomarkers over the study period, indicating a positive response to the intervention. Conclusions: The obtained results emphasize the importance of comprehensive interventions in managing arterial hypertension and its related conditions. Implementing comprehensive lifestyle changes can lead to significant health improvements and serve as an effective preventive strategy. Further research is needed to explore optimal intervention strategies for promoting societal health.
