Executive Impact & Strategic Advantage
Hypertension is a global health challenge, often undetected early due to asymptomatic onset and screening limitations. This research provides a critical breakthrough for scalable, non-invasive early detection.
The Problem: Undiagnosed Hypertension
Traditional blood pressure measurements are crucial but suffer from low screening adherence and biases like "white-coat hypertension." This leads to many patients remaining undiagnosed until disease progression, resulting in severe outcomes like stroke and heart failure.
Our Solution: AI-Powered Facial Analysis
We've developed a deep learning framework that uses standard camera facial images to identify hypertension. This non-invasive, passive method provides early, accessible, and interpretable detection, overcoming the barriers of contact sensors and clinical settings.

| Methodology | Key Advantages | Limitations & Context | Reported Performance |
|---|---|---|---|
| Our AI Approach (Facial Imaging) |
|
Requires high-quality facial images, potential for environmental factors. Limited dataset size for generalization. | Accuracy ≈ 83%, AUC ≈ 0.84 |
| Traditional Facial Analysis (CIELAB Color) |
|
Non-deep learning approach, relies on predefined color features. May lack robustness to varied lighting/skin tones. | AUC 0.82-0.83 |
| Contact-Based PPG Morphology Classification |
|
Requires contact sensors. Prone to motion artifacts and ambient light interference. Less scalable for population-level screening. | Accuracy ≈ 0.73 |
Clinical Impact & Traditional Chinese Medicine (TCM) Alignment
The model's interpretability analysis, via Grad-CAM visualizations, revealed a primary focus on the zygomatic and cheek regions for hypertension detection. These areas are clinically relevant due to their rich vascularization and sensitivity to hemodynamic changes, which are characteristic of hypertension. Intriguingly, this scientific finding strongly aligns with Traditional Chinese Medicine (TCM) diagnostic principles, where these specific facial zones are emphasized for assessing internal organ correspondence (e.g., cheek for heart/lung, periorbital for kidney).
This dual validation enhances both the scientific credibility and clinical trustworthiness of the AI system, offering a robust, physiologically interpretable tool. Such alignment fosters greater acceptance among medical professionals and opens pathways for deeper interdisciplinary research, bridging modern AI with established diagnostic wisdom.
