HeartFlow Analysis Enables Physicians to Confidently and Safely Differentiate
Patients in Need of Invasive Treatment and Patients Who Can be Managed
Medically for Coronary Artery Disease
Global Studies of Over 8,500 Patients Demonstrate Marked Improvement in Outcomes
When Physicians Utilize the HeartFlow Analysis in Diagnosis and Treatment
MUNICH, GERMANY, August 25, 2018 - Late-breaking data published and presented today
confirm that the non-invasive HeartFlow® FFRct Analysis enables physicians to effectively
differentiate patients in need of coronary stenting or bypass surgery from those who can be
managed with medications alone.
The ADVANCE Registry was published in the European Heart Journal (EHJ) and the Aarhus
University Hospital experience was published in the Journal of the American College of
Cardiology (JACC). Both studies were presented during the late-breaking science session today
at the European Society of Cardiology (ESC) conference.
In these studies, the HeartFlow Analysis changed physician management of patients and
enabled physicians to determine more efficiently which patients required invasive management
and which did not. The HeartFlow Analysis identified a set of patients at very low risk of adverse
outcomes when undergoing medical therapy, and a set whose risk was reduced when
undergoing invasive management.
The ADVANCE Registry included more than 5,000 patients in the U.S., Japan, Europe and
Canada. The Aarhus University Hospital experience included more than 3,600 patients in
Denmark who were followed for an average of two years.
“These studies confirm the role of the HeartFlow Analysis in identifying disease that other tests
may miss, and in providing reassurance to patients and doctors that some blockages are not in
need of invasive management,” said Campbell Rogers, MD, FACC, chief medical officer,
Identifying the Right Treatment for Each Patient
The HeartFlow Analysis provides FFRct values along the coronary arteries, helping physicians
to assess the impact of a blockage on blood flow. A positive FFRct value ( ≤0.80) indicates that
a coronary blockage is impeding blood flow to the heart muscle. In both studies, patients
underwent a coronary computed tomography angiogram (CTA), and when additional information
was needed, a HeartFlow Analysis 3D digital model was then used to help determine optimal

physicians to reconsider and change management plans for two-thirds of their patients. Some

who were originally scheduled to receive a coronary stent or bypass operation were safely able
to avoid the procedure and be treated with medications alone, while others who would have
received medications were redirected to stenting or bypass surgery.
In the Aarhus University Hospital experience, physicians were able confidently and safely to
differentiate higher risk patients who required additional testing, stenting or bypass surgery from
patients whose treatment required only medications.
In both studies, coronary narrowings associated with negative FFRct values ( >0.80) were
predominantly managed with medications alone and were associated with excellent outcomes,
similar to those outcomes in patients who had no or minimal narrowings.
Enabling Treatment Decisions that Lead to Safer Outcomes
In both studies, the HeartFlow Analysis helped physicians identify patients who could be treated
safely without invasive testing or treatment. In the ADVANCE Registry, among more than 1,500
patients with a negative FFRct value, the vast majority received medical therapy without
invasive testing or treatment, and none experienced adverse events.
In contrast, when the HeartFlow Analysis showed a positive FFRct value, it helped physicians
identify patients who were at higher risk for death, heart attack or emergency stenting or
bypass, and who would likely benefit from invasive management. In the Aarhus University
Hospital experience, patients with a positive FFRct value who received medical therapy alone
suffered heart attacks at a rate six times higher than that seen among patients who received a
stent or underwent bypass surgery. In the ADVANCE study, patients with positive FFRct values
were at 20-fold higher risk compared to those with negative FFRct values.
“The HeartFlow Analysis is a tool that helps me more effectively develop treatment plans with
greater confidence for my CAD patients,” said Timothy Fairbairn, MBChB, FRCP, PhD,
consultant cardiologist, Liverpool Heart and Chest Hospital and first author of the ADVANCE
registry paper. “Being able to use a non-invasive cardiac test to clearly differentiate which of my
patients need invasive procedures or are most at-risk for adverse events is instrumental in my
ability to provide them with the best care.”
About the HeartFlow FFRct Analysis
Clinicians diagnosing someone with suspected coronary artery disease (CAD) want to know as
definitively as possible if the individual has a significant blockage in their coronary arteries. They
also want to know the impact of that blockage on blood flow so they can best determine which
treatment pathway is appropriate (e.g., medical management, stenting or coronary artery
bypass grafting).
Data from a patient’s non-invasive coronary CTA are securely uploaded from the hospital’s
system to HeartFlow’s software application running in the AWS cloud. HeartFlow leverages
deep learning to create a personalized, digital 3D model of the patient’s coronary arteries. The
HeartFlow Analysis then uses powerful computer algorithms to solve millions of complex
equations to simulate blood flow and assess the impact of blockages on coronary blood flow.
The HeartFlow Analysis is provided via a secure online interface to offer actionable information
to enable clinicians to determine the optimal course of treatment. To date, clinicians around the
world have used the HeartFlow Analysis for more than 20,000 patients to aid in the diagnosis of
heart disease.

The HeartFlow Analysis provides the highest diagnostic performance compared to other
commonly available tests1 and is able to help physicians identify CAD often missed by other
tests. The technology also has demonstrated a reduction in unnecessary tests, such as an
invasive diagnostic coronary angiogram2, which can be associated with bleeding, stroke, major
blood vessel damage and other serious complications. It also significantly reduces healthcare
costs for hospitals.3
