From Signal to Score:
The EMCR Score™ Explained
HeartForce’s Electro-mechanical CAD Response Score (EMCR Score™) is a proprietary algorithm that converts SCG signals into a clear, reliable assessment of CAD risk. It brings together:
- 3D SCG waveform data
- Clinical risk factors (age, sex, hypertension, diabetes, dyslipidemia, smoking, family history)
- Symptoms such as chest pain or shortness of breath
The EMCR Score™ estimates the likelihood that a patient has coronary artery disease, defined as more than 50% blockage in at least one coronary artery. It is calculated by combining seismocardiogram (SCG) data with key risk factors and reported symptoms.

Clinical Significance of the EMCR Score™
Early Stage Assessment
Helps identify patients at risk of CAD, even before symptoms emerge.
Risk Stratification
Supports physicians in identifying patients who require advanced diagnostic imaging, such as CCTA or ICA.
High-Risk Screening
Fills a critical gap in current diagnostic workflows by revealing CAD in high-risk patients with multiple CAD-associated risk factors.
What our Risk Categories Mean for Clinical Action
Based on clinical research and the latest recommended guidelines (“2024 ESC guidelines for the management of chronic coronary syndromes”), the EMCR Score™ was divided into five categories to aid clinical interpretation:
Very Low Risk (EMCR < 0.05):
This range indicates a very low prevalence of significant CAD (less than 5%).
Low Risk (EMCR between 0.05 and 0.15):
This range indicates a low prevalence of significant CAD (between 5% and 15%). For such patients, physicians may reasonably defer further diagnostic testing, while considering the overall clinical context.
Intermediate Risk (EMCR between 0.15 and 0.50):
This range suggests the need for further clinical evaluation through non-invasive measures such as Coronary Computed Tomography Angiography (CCTA) medical imaging. Expected prevalence between (15% and 50%).
High Risk (EMCR between 0.50 and 0.85):
This category indicates a high prevalence of significant CAD (between 50% and 85%). Further clinical measures, such as Invasive Coronary Angiography (ICA) or CCTA medical imaging, are suggested.
Very High Risk (EMCR > 0.85):
This category indicates a high prevalence of significant CAD (greater than 85%). Further clinical measures, such as ICA, are suggested.
