Cardio-HART for Commissioners:
Invest in Early Detection,
Save Lives and Costs
- Echo Referral Reduction: Up to 50% of primary‑care echo referrals are unnecessary1.
- Cost avoidance: Saved echo costs (~£80–£100 each) and reduced emergency admissions.
- Early intervention ROI: Detecting and treating heart failure early prevents expensive hospitalisation—costing ~£4,000 per acute HF admission2.
Immediate & Long-Term Impact
Why Cardio-HART for commissioners Delivers ROI
1. Cut Low-Value Testing
- ~50% of echo referrals from GPs may be unnecessary—Cardio‑HART filters these, saving echo slots and cutting costs.
- NT‑proBNP underused: fewer than 20% are tested, contributing to high downstream echo use3.
2. Prevent Crisis Care
- 75% of HF diagnoses occur in hospital. Delayed diagnosis triggers costly A&E admissions—avoidable with early testing4.
- One avoided HF hospitalisation offsets the cost of Cardio‑HART testing for hundreds of patients.
3. Promote Health Equity
- Echo services are concentrated in urban hospital settings.
- Rural and underserved areas get equitable access via local GP-based Cardio‑HART.
- Trial data shows 4‑fold variation in echo access across regions5.

Patient-Centred Care—No Trade-Offs
Cardio‑HART is patient-focused and system-smart:
- Convenient: Simple GP-based test with no hospital visit
- Rapid: All results in under 10 minutes—allowing same-day decisions
- Accurate: 96% agreement with echocardiography for key conditions
- Lower burden: Fewer hospital visits ease stress on families
Public Health, Regional, and National Goals Alignment
- Supports NHS Long Term Plan: earlier HF diagnosis, reduced low‑value diagnostics.
- Meets Diagnostics Recovery & Renewal objectives for better capacity use.
- National climate targets: aligns with NHS net zero by reducing travel and imaging footprint.
Summary Table
Challenge | Cardio‑HART Solution | Impact |
---|---|---|
Overloaded echo services | Frontline ECG+AI with echo-level insights | Save echo capacity for complex cases |
Late diagnosis in A&E | Early detection in primary care | Reduce acute admissions |
Urban–rural inequity | Portable GP-based testing | Fairer, local access |
CO₂ from travel & imaging | Fewer referrals and scans | Supports NHS carbon targets |
High downstream costs | Fewer unnecessary tests & hospitalisations | Multi-million £ savings/year |

The Bottom Line
A modest investment in Cardio‑HART transforms cardiac care at low cost:
- Better, earlier diagnosis
- Lower system-wide costs
- Healthier, happier patients
- Progress toward carbon neutrality
