Heart Metrics - Quantifying Heart Health
Get Started

Coronary artery disease (CAD) affects 17.6 million Americans and results in nearly half a million deaths per year. The estimated indirect and direct costs of CAD are expected to triple over the next two decades from $273 to $881 billion. Despite access to sophisticated diagnostic imaging tests at a cost of $6 billion per year, over 1,000,000 US patients are referred to unnecessary invasive catheterization procedures, resulting in patient risk and a staggering financial burden to the US healthcare system.

the technology - tafe TM

HeartMetrics has developed an automated non-invasive diagnostic algorithm to rapidly quantify coronary blood flow from a standard computed tomography angiography (CTA) image of the heart. This technology (Transluminal Attenuation Flow Encoding) TAFE TM is based upon contrast dispersion fluid dynamics and helps identify coronary disease that causes a reduction of blood flow to the heart muscle. Identification of vessel specific ischemia greatly facilitates decisions about whether patients should be referred to the catheterization laboratory/operating room for invasive therapy or be managed by medications only.
