Remote photoplethysmography (rPPG), which estimates physiological signals from facial video recordings, has emerged as a potential contactless alternative for blood pressure monitoring.

In a study presented at the ESH 2026, investigators conducted a prospective, single-arm observational study at a specialized hypertension outpatient clinic in Brazil to evaluate the accuracy of the iSelfie Heart Health software for estimating systolic and diastolic blood pressure. The study included 641 participants who met eligibility criteria and underwent paired blood pressure assessments using both hospital-grade validated devices and the rPPG platform.

Findings

• A total of 641 participants were included in the final analysis comparing rPPG-based blood pressure estimation with standard clinical measurements.
• Personalized calibration improved agreement between rPPG-estimated and standard-of-care blood pressure measurements across both systolic and diastolic blood pressure ranges.
• The rPPG platform achieved a sensitivity of 84.6% for detecting hypertension.
• Specificity for hypertension detection was 93.4%, indicating a high ability to correctly identify individuals without hypertension.

The findings suggest that rPPG-based blood pressure estimation may serve as a useful adjunct for home and ambulatory blood pressure monitoring.
