About Heartflow
Heartflow is the global leader in AI-driven coronary artery disease (CAD) management, transforming how CAD — the world’s leading cause of death — is diagnosed and treated. Our advanced technology generates personalized, precision 3D heart models from a single CT scan, providing clinicians with the clarity and confidence to deliver earlier, more effective treatments — transforming CAD into a disease that can be managed for life. Heartflow One is the only complete, non-invasive, precision coronary care platform providing patient insights throughout the guideline-directed coronary CTA pathway. The AI-driven platform — including Roadmap™ Analysis, FFRct Analysis and Plaque Analysis — is supported by ACC/AHA guidelines and backed by more than 625 peer-reviewed publications. With over 650,000 patients treated, more than 1,800 leading institutions adopting our solution, and 99.5% of U.S. lives covered — Heartflow is redefining the standard of coronary care. We're a global company, with employees across the United States, Europe and Japan. Our headquarters are in San Francisco, California, with additional offices in California, Texas, the UK and Japan. We believe CAD shouldn’t be a silent threat. We’re changing the story of CAD by making it screenable, diagnosable, and manageable — empowering clinicians to save lives and giving patients more time for what matters most.
