How It Works

Five steps to
cardiac clarity

From wearable sync to SHAP explainability — CardioGuardAI turns raw vitals into actionable intelligence in 98 milliseconds.

01
Tap to Scan
Patient opens CardioGuardAI, taps "Start Free Scan", and grants permission to access wearable data (Apple Watch, Fitbit, Garmin) or enters vitals manually.
02
Real-time Data Stream
Heart rate, SpO₂, blood pressure, temperature, and ECG lead II flow into TimescaleDB at 3-second intervals. Antigravity engine receives live updates.
03
XGBoost Risk Scoring
Antigravity AI model (XGBoost + ONNX + PyTorch) processes all vitals in 98ms. Generates a CVD risk score (0–100) and flags 6 cardiac findings (STEMI, AF, etc.).
04
SHAP Explainability
Patient sees animated SHAP waterfall: "ST-Elevation +0.42 | Age (58) +0.28 | Hypertension +0.21 | SpO₂ −0.06". Every factor explained.
05
Smart Triage & Action
If score > 70: SOS Emergency Dispatch triggers. If 40–70: CardioSaathi recommends doctor visit. If < 40: Wellness tips + medicine reminders.
📱
Tap to Scan
Supports 50+ wearable integrations. Offline mode available for areas without connectivity.

Understanding Cardiovascular Disease: The Silent Epidemic in India

Cardiovascular disease (CVD) is the leading cause of death in India, accounting for nearly 28% of all deaths. Unlike many other countries, CVD strikes Indians a decade earlier — often in their 40s and 50s. This comprehensive guide explores the unique risk factors affecting the Indian population, including genetic predisposition, dietary habits, and the rising prevalence of diabetes and hypertension. Learn why early detection through AI-powered tools like CardioGuardAI can be life-saving, and discover the key biomarkers that predict cardiac events years before they occur.

How Chronic Stress Damages Your Heart — And What to Do About It

Chronic stress triggers a cascade of hormonal responses that directly damage your cardiovascular system. Cortisol elevates blood pressure, adrenaline increases heart rate, and inflammation markers rise — all contributing to atherosclerosis. This article explores the science behind stress-induced heart disease, why India's work culture is a risk factor, and evidence-based stress management techniques including pranayama, meditation, and cognitive behavioral strategies.

Real-time STEMI Alerts
When Antigravity scores a patient above 70/100, your phone rings within 15 seconds. ECG snapshot, SHAP waterfall, and patient history attached automatically. No more waiting for ambulance calls.
Weekly SHAP Patient Reports
Every Monday, CardioGuardAI emails your patient panel's risk trajectory — which factors improved, which worsened, medicine adherence rate, and ECG trend. Saved 4–6 hours per cardiologist per week in trials.
FastAPI Integration
Plug CardioGuardAI into your hospital's HIS via REST API. POST /v1/risk-score returns a JSON SHAP report in 98ms. GET /v1/patient/{id}/vault delivers AES-256 encrypted DICOM + PDF records instantly.
One-tap Video Consultation
Patient taps "Video Call" in their Medical Vault → you receive a push notification with their real-time vitals, latest ECG, and ABHA record already loaded. No app switching. Encrypted end-to-end.
