Heartflow Reports Fourth Quarter and Full Year 2025 Financial Results

MOUNTAIN VIEW, Calif., March 18, 2026 (GLOBE NEWSWIRE) — Heartflow, Inc. (Heartflow) (Nasdaq: HTFL), the leader in AI technology for coronary artery disease (CAD), today reported financial results for the fourth quarter and full year ended December 31, 2025. Fourth Quarter 2025 Highlights Total revenue of $49.1 million, a 40% increase year-over-yearGross margin of 79.5%, non-GAAP gross margin of 79.9%Net operating loss of $17.8 million, non-GAAP net operating loss of $12.5 millionU.S. installed base of 1,465 accounts as of December 31, 2025U.S. Plaque installed base of 489 accounts as of December 31, 2025Aetna began coverage of Heartflow Plaque Analysis, bringing total U.S. covered lives for Plaque to approximately 75% 2026 Annual Guidance Total revenue of $218 million to $222 million (approximately 24% to 26% growth year-over-year)Non-GAAP gross margin of 80% to 81% “Our strong fourth quarter performance concluded a record year for Heartflow,” said John Farquhar, President and CEO of Heartflow. “The accelerating adoption of the Heartflow Platform, combined with our disciplined execution across commercial, innovation, and clinical initiatives, drove 40% fourth quarter and full year revenue growth and record gross margins. We also made significant strides in scaling account activations and driving early physician adoption of Heartflow Plaque Analysis. Our 2026 guidance reflects strong business fundamentals, a solid foundation for growth, and high confidence in consistent execution. With commercial, innovation and clinical catalysts on the horizon, our conviction in the business has never been higher.” Fourth Quarter 2025 Financial ResultsTotal revenue was $49.1 million, a 40% increase year-over-year. U.S. revenue was $44.8 million, a 41% increase year-over-year. International and other revenue was $4.3 million, a 35% increase year-over-year. The year-over-year increase in total global revenue was primarily attributable to an increase in total U.S. FFRCT volume. Gross profit was $39.1 million, compared to $26.3 million in the prior year period. Non-GAAP gross profit was $39.2 million, compared to $26.3 million in the prior year period. Gross margin was 79.5%, compared to 75.0% in the prior year period. Non-GAAP gross margin was 79.9%, compared to 75.3% in the prior year period. The year-over-year gross margin expansion was primarily attributable to an increase in revenue case volume and improved production team productivity driven by AI efficiency initiatives, partially offset by the hiring and training of production team personnel. Total operating expenses were $56.8 million, or 116% of total revenue, compared to $42.3 million, or 121% of total revenue, in the prior year period. Non-GAAP total operating expenses were $51.7 million, or 105% of total revenue, compared to $39.9 million, or 114% of total revenue, in the prior year period. The year-over-year operating expense increase was primarily attributable to increased investment in sales personnel and related expenses, as well as increased investments in technology and clinical research. Net operating loss was $17.8 million, compared to $16.1 million in the prior year period. Non-GAAP net operating loss was $12.5 million, compared to $13.5 million in the prior year period. Net loss was $24.4 million, or ($0.29) net loss per share, compared to $33.0 million, or ($5.59) net loss per share, in the prior year period. Net loss for the fourth quarters of 2025 and 2024 included a noncash charge of $9.3 million and $11.9 million, respectively, resulting from the remeasurement of the fair value of the Company’s common stock warrant liability. As of October 22, 2025, the warrant holder net exercised all warrants in full. Therefore, the fourth quarter of 2025 is the last quarter that movements in the Company’s stock price will trigger a warrant revaluation and result in a noncash charge to net loss. Non-GAAP net loss was $9.8 million, or ($0.12) non-GAAP net loss per share, compared to $18.6 million, or ($3.15) non-GAAP net loss per share, in the prior year period. Adjusted EBITDA was ($11.1) million, compared to ($12.0) million in the prior year period. Full Year 2025 Financial ResultsTotal revenue was $176.0 million, a 40% increase year-over-year. U.S. revenue was $160.6 million, a 41% increase year-over-year. International and other revenue was $15.4 million, a 26% increase year-over-year. The year-over-year increase in total global revenue was primarily attributable to an increase in total U.S. FFRCT volume. Gross profit was $135.2 million, compared to $94.4 million in the prior year period. Non-GAAP gross profit was $135.6 million, compared to $94.8 million in the prior year period. Gross margin was 76.8%, compared to 75.1% in the prior year period. Non-GAAP gross margin was 77.0%, compared to 75.3% in the prior year period. The year-over-year gross margin expansion was primarily attributable to an increase in revenue case volume and improved production team productivity driven by AI efficiency initiatives, partially offset by the hiring and training of production team personnel. Total operating expenses were $199.3 million, or 113% of total revenue, compared to $155.7 million, or 124% of total revenue, in the prior year period. Non-GAAP total operating expenses were $185.7 million, or 105% of total revenue, compared to $145.8 million, or 116% of total revenue, in the prior year period. The year-over-year operating expense increase was primarily attributable to increased investment in personnel and related expenses, as well as increased investments in technology and clinical research. Net operating loss was $64.1 million, compared to $61.2 million in the prior year period. Non-GAAP net operating loss was $50.1 million, compared to $51.0 million in the prior year period. Net loss was $116.8 million, or ($3.17) net loss per share, compared to $96.4 million, or ($17.98) net loss per share, in the prior year period. Non-GAAP net loss was $59.9 million, or ($1.62) non-GAAP net loss per share, compared to $69.6 million, or ($12.98) non-GAAP net loss per share, in the prior year period. Adjusted EBITDA was ($44.7) million, compared to ($45.7) million in the prior year period. Cash, cash equivalents and investments totaled $280.2 million as of December 31, 2025.

Use of Non-GAAP MeasuresTo supplement its consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles (GAAP), the Company discloses non-GAAP gross profit and non-GAAP gross margin, non-GAAP total operating expenses, non-GAAP research and development expense, non-GAAP selling, general and administrative expense, non-GAAP net operating loss, non-GAAP net loss, non-GAAP net loss per share, basic and diluted, and Adjusted EBITDA (collectively, the “Non-GAAP Measures”) in this press release. As used by the Company, these measures are adjusted to exclude stock-based compensation expense from the comparable GAAP financial measure. Non-GAAP net loss and non-GAAP net loss per share, basic and diluted, are also adjusted for change in fair value of common stock warrant liability, change in fair value of derivative liability and loss on extinguishment of debt. In addition, Adjusted EBITDA is calculated by adding back to net loss or excluding, as appropriate, interest income and expense, provision for income taxes, and charges for depreciation and amortization and is further adjusted by adding back in or excluding, stock-based compensation and, as appropriate, other income and expense items that are not reflective of the Company’s underlying continuing operating performance. Reconciliations of the Non-GAAP Measures to their most directly comparable GAAP financial measures are provided in the financial statement tables included at the end of this press release, and investors are encouraged to review the reconciliations. The Company believes the presentation of the Non-GAAP Measures, when shown in conjunction with the corresponding GAAP measures, provides useful information to investors as it provides visibility to the Company’s underlying continuing operating performance from period to period by excluding the impact of stock-based compensation and certain other items that are not reflective of the Company’s ongoing operations. Because of the variety of equity awards used by companies, the varying methodologies for determining stock-based compensation expense, the subjective assumptions used in those determinations, and the volatility in valuations that can be driven by market conditions outside the Company’s control, we believe excluding stock-based compensation expense enhances the ability of management and investors to understand and assess the underlying performance of our business over time and compare it against our peers, a majority of whom also exclude stock-based compensation expense from their non-GAAP results. With respect to the presentation of Adjusted EBITDA, the Company believes it is a useful measure to evaluate the Company’s operating performance and it is used by the Company to evaluate ongoing operations and for planning and forecasting purposes. Adjusted EBITDA is also a measure frequently used by analysts, investors and other interested parties to evaluate companies in our same industry. The Company’s definition of the Non-GAAP Measures may differ from similarly titled measures used by others. The Non-GAAP Measures should be considered only as a supplement to, and not as a substitute for, or superior to, their most directly comparable GAAP financial measures. Because the Non-GAAP Measures exclude the effect of items that increase or decrease the Company’s reported results of operations, management strongly encourages investors to review the reconciliations to the most comparable GAAP financial measures at the end of this press release and, when they become available, the Company’s consolidated financial statements and publicly filed Securities and Exchange Commission (“SEC”) reports in their entirety. The Company is not able to provide a reconciliation without unreasonable efforts of its forward-looking guidance related to non-GAAP gross margin to the most directly comparable GAAP financial measure due to the unknown effect of stock-based compensation that is material to the comparable GAAP financial measure.

Heartflow Builds Evidence Base Across the Heart Disease Care Continuum, From Precision Risk Stratification to CT-Guided Intervention Planning

Heartflow PCI Navigator is the only integrated, AI-driven PCI planning tool that gives interventional cardiologists a patient-specific 3D model detailing anatomy, plaque composition, and lesion-specific physiology, all aligned to optimize potential stent placement.

Three presentations at ACC reinforce Heartflow’s AI-powered technology predicts MACE, drives superior lipid outcomes and results in cost-effective care First patient enrolled in pioneering NAVIGATE-PCI Registry assessing impact of Heartflow PCI Navigator on clinical strategy, efficiency and physician confidence across 5,000 patients  MOUNTAIN VIEW, Calif., March 16, 2026 (GLOBE NEWSWIRE) — Heartflow, Inc. (Heartflow) (Nasdaq: HTFL), the leader in AI technology for coronary artery disease (CAD), today announced new clinical evidence and a landmark registry launch that together advance the company’s vision of transforming CAD management across every stage of the patient journey. At the American College of Cardiology (ACC) Annual Scientific Session, Heartflow is presenting new clinical evidence that further establishes AI-powered Heartflow Plaque Analysis as the leading tool for identifying high-risk patients earlier and guiding more effective medical management. Simultaneously, Heartflow has enrolled the first patient in the NAVIGATE-PCI Registry, the first large-scale effort to evaluate the real-world impact of CT-guided percutaneous coronary intervention (PCI) planning on clinical strategy, procedural efficiency and physician confidence. The registry is evaluating how often treatment plans change when physicians use the AI-driven insights provided by Heartflow PCI Navigator compared to angiography alone. “These milestones reflect tremendous progress toward Heartflow’s goal of transforming coronary artery disease from the world’s leading cause of death into a condition that can be detected early, diagnosed accurately, and managed for life,” said Campbell Rogers, M.D., F.A.C.C., Chief Medical Officer at Heartflow. “The Heartflow Plaque Analysis data presented at ACC and the launch of the NAVIGATE-PCI Registry represent important steps in building the rigorous real-world evidence needed to support AI-driven decision-making across the full continuum of cardiovascular care. From identifying high-risk patients earlier and improving how they are managed to generating the evidence needed to guide more precise interventions when required, Heartflow is giving physicians deeper insights and greater confidence so they can deliver better outcomes for patients.” Heartflow Plaque Analysis: New Clinical Evidence for Earlier Risk Stratification and Management Heartflow Plaque Analysis will be featured in three ACC 2026 presentations, covering long-term validation of risk stratification, real-world comparative effectiveness in lipid management, and economic sustainability. Collectively, these data reinforce Plaque Analysis as a personalized, clinically actionable and cost-effective solution for CAD management. AI-Based Coronary Plaque Analysis and Adverse Cardiovascular Events: The Mass General Brigham CCTA Registry (Poster 1082-09, March 29, 10:06 a.m. CDT)This cohort, based on a large-scale registry tracking over 15,000 patients, with up to 16 years of follow-up, demonstrated that Plaque Analysis is a powerful predictor of major adverse cardiovascular events (MACE), even after accounting for traditional risk factors and the severity of coronary stenosis. The findings reveal that patients with extensive plaque volume face a fourfold higher risk of such events. This robust, real-world data solidifies Heartflow Plaque Staging as the most powerful CTA-based independent predictor for personalized risk stratification, enabling clinicians to identify high-risk individuals beyond conventional metrics. “Stenosis has long been our primary lens for evaluating coronary risk, but it tells an incomplete story, as this registry demonstrates. With over 15,000 patients and 16 years of follow-up, we now have compelling real-world evidence that total plaque volume independently drives adverse events, regardless of risk factors or the presence of anatomical stenosis,” said Ron Blankstein, M.D., Director of Cardiac Computed Tomography at Brigham and Women’s Hospital, and Professor of Medicine and Radiology at Harvard Medical School. “These findings catalyze a meaningful shift in how we approach risk stratification by more accurately identifying patients who might otherwise have been characterized as having lower risk based on conventional assessment and optimizing management based on their actual disease burden.” Comparative Effectiveness of Coronary Computed Tomographic Angiography With or Without AI-Plaque Analysis and Stress Testing on Lipid Lowering After One Year: A Primary Analysis of the DECIDE Registry (Poster 1469-058, March 29, 12:30 p.m. CDT)This analysis, involving nearly 3,800 patients, compared patient management guided by CCTA with Plaque Analysis versus traditional stress-test-guided care over a one-year follow-up. A significantly higher portion of patients whose care was informed by Plaque Analysis initiated lipid-lowering therapy and achieved guideline-recommended LDL goals (

Heartflow Expands GAMEFILM Registry to NBA and NHL Alumni, Precisely Measuring Heart Disease Risk in Former Professional Athletes

NBA legend Muggsy Bogues joins effort to detect and manage coronary artery disease in retired players using AI-powered Heartflow AnalysisMOUNTAIN VIEW, Calif., Feb. 12, 2026 (GLOBE NEWSWIRE) — Heartflow, Inc. (Heartflow) (Nasdaq: HTFL), the leader in AI technology for coronary artery disease (CAD), today announced a significant expansion of its groundbreaking GAMEFILM Registry. Building on a successful initial phase enrolling retired National Football League (NFL) athletes, the study will now extend to include former players from the National Basketball Association (NBA) and the National Hockey League (NHL), broadening Heartflow’s initiative to protect the heart health of professional athletes across major sports. Retired NBA star Muggsy Bogues was one of the first former professional basketball players to join the GAMEFILM Registry and receive a CAD assessment with Heartflow’s AI-driven technology. “My 14-year career as a professional athlete taught me the importance of staying on top of your health, especially heart health. I joined Heartflow’s GAMEFILM Registry as soon as I heard about it because I’ve lost too many friends to cardiovascular disease,” said former NBA point guard Muggsy Bogues. “Many of us push our bodies to the limits, and sometimes the signs of underlying issues can be overlooked. Heartflow Analysis offers an easy way to get a precise picture of what’s going on inside, without invasive procedures. I’m excited to see this technology benefit more athletes, giving them and their doctors a powerful tool for proactive heart care.” Heart disease is the leading cause of death in the United States and worldwide. It is known as the “silent killer” because it can progress for years without obvious signs or symptoms. For professional athletes who place immense, continuous demands on their cardiovascular systems, underlying heart issues can be easily masked. Heartflow Plaque Analysis provides a thorough understanding of coronary plaque burden, which is essential for physicians to identify high-risk patients early and enable timely, preventative interventions. Four out of five heart attacks and strokes are preventable with lifestyle and nutrition changes if patients at high risk are identified early.1 The GAMEFILM Registry has already enrolled over 140 retired athletes from the NFL, NBA, and NHL. The study, currently active at 15 sites across the United States, aims to enroll up to 300 former players to better understand the prevalence, risk factors, severity, and treatment protocols for cardiovascular disease in this population. To do so, the registry addresses how advanced coronary computed tomography angiography (CCTA) imaging and AI-powered insights from Heartflow’s first-of-its-kind non-invasive technology can identify different types of plaque in the coronary arteries — including those most likely to cause a cardiac event — and measure the effect on blood flow to the heart.2 “Expanding our GAMEFILM Registry to include NBA and NHL athletes marks a pivotal moment for Heartflow, demonstrating our mission to revolutionize how heart disease is diagnosed, measured and managed,” said John Farquhar, President and CEO of Heartflow, and an NFL alumnus. “Heartflow’s precision diagnostic capability will not only advance the health and safety of these athletes, but also generate invaluable insights that will benefit cardiovascular care more broadly.” The expansion of the GAMEFILM registry will deepen understanding of how high-performance sports impact heart health over time. This data is expected to contribute significantly to the development of tailored screening protocols, preventative strategies, and personalized treatment plans. “Cardiovascular disease in former professional athletes is a paramount concern, but there’s much we still don’t understand about the disease in this population,” said Jeffrey L. Boone, M.D., GAMEFILM Registry Primary Investigator and Founder and Medical Director of the Boone Heart Institute. “We’ve seen the invaluable insights gained from our work with NFL alumni, identifying risks and guiding interventions. Bringing this same proactive, precision cardiovascular care to basketball and hockey players, who are also at unique risk due to the physical intensity of their sports, is a vital step in ensuring their long-term health.” Heartflow is actively collaborating with organizations supporting former professional athletes to facilitate enrollment and to integrate the GAMEFILM Registry’s insights into existing health and wellness programs. This initiative underscores Heartflow’s dedication to managing heart disease through partnering with physicians to generate robust, high-quality clinical evidence.

Heartflow Plaque Analysis Now Covered by Aetna Insurance Plans Nationwide and for the Majority of Insured Lives in the U.S.

Fourth major national payer releases positive comprehensive coverage for AI-powered Heartflow Plaque AnalysisMOUNTAIN VIEW, Calif., Jan. 06, 2026 (GLOBE NEWSWIRE) — Heartflow, Inc. (Heartflow) (Nasdaq: HTFL), the leader in AI technology for coronary artery disease (CAD), today announced Heartflow Plaque Analysis is now covered by Aetna across all lines of business, including Commercial, Medicare Advantage, and Aetna Better Health Medicaid plans. Aetna is the fourth major national commercial insurer to update its policies to cover Heartflow Plaque Analysis to fully align with the guidelines issued by radiology benefit manager EviCore, following similar decisions by Humana, Cigna, and UnitedHealthcare. Heartflow Plaque Analysis is covered for the majority of insured lives across the United States. This coverage milestone follows the American Medical Association’s recent implementation of the new Category I Current Procedural Terminology (CPT®) payment code 75577 for Heartflow Plaque Analysis, effective January 1, 2026, which established 0.85 relative value units (RVUs) and a combined total of 4.00 RVUs for physicians performing the service. “Aetna’s decision to cover Heartflow Plaque Analysis nationwide is a pivotal step in expanding access to our AI-driven plaque quantification and characterization technology,” said John Farquhar, President and CEO of Heartflow. “With four major commercial payers and Medicare now recognizing the innovation and value of our platform, more clinicians can gain earlier, clearer insights into coronary plaque. More patients will benefit from early detection and precise quantification of plaque with Heartflow Plaque Analysis, leading to more personalized treatment strategies and improved prognostic assessment, helping set a new benchmark for cardiovascular care.” The updated coverage became effective on December 23, 2025 for Aetna patients with acute or stable chest pain and mild-to-moderate narrowing of coronary arteries (1-69% stenosis) identified on coronary CTA. The policy expands access for patients to AI-driven plaque analysis, supporting earlier diagnosis, personalized risk stratification, and more precise management of CAD. The new CPT code was issued in response to increased utilization of AI-powered plaque quantification and characterization technology like Heartflow Plaque Analysis and strong clinical evidence supporting its value. Together, broader national payer coverage and Category I reimbursement position the Heartflow platform as the highest-value pathway in cardiac CT, expanding access and supporting practical adoption in clinical practice. Heartflow’s continued advancement of Heartflow Plaque Analysis builds on the real-world evidence demonstrated in the landmark DECIDE Registry data, the largest prospective registry evaluating the clinical impact of Heartflow Plaque Analysis on medical management decisions. The DECIDE registry showed that more than 50% of patients had their medical management changed when Heartflow Plaque Analysis with Heartflow Plaque Staging* was added compared to their management based on CCTA alone.1 A retrospective analysis of symptomatic patients from a cohort of the FISH&CHIPS Study presented at the AHA Scientific Sessions 2025 provided the largest validation to date of the Heartflow Plaque Staging framework based on total plaque volume measurement as a predictor of future heart attacks or cardiovascular death.2 Heartflow Plaque Analysis is the only FDA-cleared, AI-powered plaque quantification tool with 95% agreement to the gold standard, IVUS, using blinded core lab adjudication.3 About Heartflow’s Technology and ResearchHeartflow’s technology is redefining precision cardiovascular care through clinically-proven AI and the world’s largest coronary imaging dataset.

Heartflow Plaque Analysis Now Supported by Scientific Statements From American College of Cardiology and American Heart Association for Personalized Management of Patients with Suspected CAD

Reinforces Role of AI-Powered Quantitative Coronary Plaque AssessmentMOUNTAIN VIEW, Calif., Dec. 18, 2025 (GLOBE NEWSWIRE) — Heartflow, Inc. (Heartflow) (Nasdaq: HTFL), the leader in AI technology for coronary artery disease (CAD), announced the American College of Cardiology (ACC) and the American Heart Association (AHA) published new scientific statements supporting the prognostic value of quantifying coronary plaque and reinforcing the critical role of the coronary computed tomography angiography (CTA) + Heartflow pathway in CAD patient management. The ACC’s consensus recommendations, published this week in JACC: Cardiovascular Imaging, highlight the importance of quantitative plaque assessment and underscore the benefits of adopting AI-powered Heartflow Plaque Analysis for personalized, precision cardiac care.1 The ACC statement elevates plaque analysis from an emerging technology to a defined clinical consideration in CAD management, outlining appropriate patient selection and best practices for interpreting and reporting. In direct alignment with the ACC’s call for rigorous quality assurance, reproducible results, and “human in the loop” analysis, Heartflow delivers a differentiated standard for clinical plaque quantification by combining AI-driven analysis with expert quality review. Heartflow Plaque Analysis is the only FDA-cleared, AI-powered plaque quantification tool with 95% agreement to the gold standard, IVUS, using blinded core lab adjudication.2 This rigor, together with Heartflow’s commitment to standardized reporting and advanced algorithmic approaches such as adaptive thresholds, reflects a level of validation and quality oversight consistent with ACC guidance. The AHA statement, published recently in Circulation, reinforces plaque burden and composition as central in managing nonobstructive CAD.3 The expert authors emphasize that patients with nonobstructive CAD should not be considered low-risk, recognizing that coronary plaque burden, extent, and composition are major determinants of outcomes. Earlier this year, a commission perspective published in The Lancet called for a fundamental shift in managing CAD, urging clinicians to focus on identifying and managing plaque early, before the opportunity for prevention has been lost.4 Together, the scientific statements from ACC and AHA reinforce that broader paradigm shift toward understanding plaque burden, not just artery obstruction, in modern CAD management. “The ACC and AHA scientific statements address an important need by providing evidence-based consensus recommendations for clinicians and imagers, solidifying coronary CTA-based quantitative plaque analysis as a powerful tool for enhanced risk stratification in patients with suspected CAD,” said Ron Blankstein, M.D., writing committee member for both the ACC and AHA statements, Director of Cardiac Computed Tomography at Brigham and Women’s Hospital, and Professor of Medicine and Radiology at Harvard Medical School. “These statements highlight the limitations of current methods to assess risk based on risk factors or stenosis severity alone. Integrating AI-powered technology into clinical practice using ACC and AHA’s guidance can help clinicians move beyond diagnosing blockages, toward predicting and preventing major cardiovascular events.” Both the ACC and AHA scientific statements support the use of quantitative coronary plaque analysis to identify high-risk patients, enabling the immediate and appropriate initiation of preventive treatment. Heartflow Plaque Analysis addresses the need to quantify disease following visual detection of plaque, and is delivered instantly upon order to maintain seamless clinical integration and enable timely clinical decision-making. “The ACC and AHA scientific statements signal growing consensus that plaque assessment is essential for risk stratification, prevention, and long-term CAD management. Heartflow Plaque Analysis enables more precise risk stratification for personalized, preventive treatment plans,” said Campbell Rogers, M.D., F.A.C.C., Chief Medical Officer at Heartflow. “The expert guidance articulates the need for rigorous validation and standardization, which Heartflow is uniquely positioned to address, given our technology and quality systems already align with these stringent recommendations. We are energized by the opportunity to continue collaborating with clinicians as a catalyst to redefine and improve precision cardiovascular care.” The ACC and AHA’s scientific statements reflect a growing body of clinical evidence further substantiating the prognostic significance of Heartflow Plaque Analysis. A retrospective analysis of symptomatic patients from a cohort of the FISH&CHIPS Study presented at the AHA Scientific Sessions 2025 provided the largest validation to date of the Heartflow Plaque Staging framework based on total plaque volume measurement as a predictor of future heart attacks or cardiovascular death.5 The company is generating additional real-world evidence through the DECIDE registry, the largest prospective registry evaluating the clinical impact of Heartflow Plaque Analysis on medical management decisions. The DECIDE registry showed that more than 50% of patients had their medical management changed when Plaque Analysis with Plaque Staging* was added compared to their management based on CCTA alone.6 About Heartflow’s Technology and ResearchHeartflow’s technology is redefining precision cardiovascular care through clinically-proven AI and the world’s largest coronary imaging dataset.

Heartflow FFRCT Analysis Delivers Prognostic Power and Significant Cost Savings in New Analyses of Over 90,000 Patients with Coronary Artery Disease

Lesion-specific FFRCT predicts individual cardiovascular outcomes and delivers greater-than-modeled cost savings for real-world population in FISH&CHIPS analyses from England’s National Health ServiceMOUNTAIN VIEW, Calif., Dec. 11, 2025 (GLOBE NEWSWIRE) — Heartflow, Inc. (Heartflow) (Nasdaq: HTFL), the leader in AI technology for coronary artery disease (CAD), announced two new analyses from FISH&CHIPS, a real-world, multicenter, retrospective study of more than 90,000 patients conducted by the National Health Service (NHS) in England, representing the largest fractional flow reserve (FFRCT) study ever conducted. The data, presented today at the European Society of Cardiology’s European Association of Cardiovascular Imaging (EACVI) conference in Vienna, provide the strongest real-world evidence to date that Heartflow FFRCT Analysis derived from coronary computed tomography angiography (CTA) improves diagnostic decision-making, predicts future cardiovascular events, and delivers substantial, system-wide cost savings. “These real-world data show that coronary CTA plus Heartflow FFRCT Analysis brings both clinical and economic value when utilized in a large health system,” said Timothy Fairbairn, Ph.D., principal investigator for the FISH&CHIPS study, Liverpool Heart and Chest Hospital, and Associate Professor at the University of Liverpool, UK. “The introduction of Heartflow FFRCT Analysis into the NHS resulted in fewer avoidable tests, lower inpatient and outpatient costs, and substantial overall savings for both the hospitals and patients. It’s a compelling example of how noninvasive AI-powered technology can reshape care pathways at scale.” Lesion-Specific Heartflow FFRCT Analysis Predicts Individual Cardiovascular OutcomesIn a nationwide analysis of 7,836 patients who underwent FFRCT in the FISH&CHIPS study, investigators evaluated the prognostic value of Heartflow FFRCT Analysis across individual outcomes, including myocardial infarction (MI), cardiovascular mortality, all-cause mortality, and revascularization. Key findings include:1 The lower the FFRCT values, the higher the risk of MI, revascularization, cardiovascular death, and all-cause death, independent of traditional cardiovascular risk factors.Patients with the lowest FFRCT values faced a four-fold increased risk of heart attack and a three-fold increased risk of cardiovascular death.Lesion-specific FFRCT (measured just beyond a specific stenosis) was the strongest predictor in the study of MI and revascularization, compared to distal vessel FFRCT (measured at the end of the artery). Heartflow FFRCT Analysis Delivers Greater-Than-Expected Cost SavingsA separate analysis of FISH&CHIPS data evaluated the cost-effectiveness of incorporating Heartflow FFRCT Analysis into the diagnostic pathway for stable CAD. The findings showed that the national program:2 Reduced downstream cardiovascular testing, including invasive coronary angiography.Increased appropriate revascularization and improved revascularization ratios.Produced £1,042 GBP ($1,394 USD) in per-patient cost savings at two years, substantially exceeding the cost savings modeled by NHS and the National Institute for Health and Care Excellence (NICE) during initial assessment and adoption. This suggests a potential £25 million GBP ($33.45 million USD) cost savings per year for the health system.Demonstrated cost savings beginning in the first year, with benefits persisting in lifetime modeling. “These data provide compelling real-world evidence underscoring the clinical value of lesion-specific Heartflow FFRCT Analysis to provide precise, localized physiological assessments,” said Campbell Rogers, M.D., F.A.C.C., Chief Medical Officer at Heartflow. “We now see that lesion-specific FFRCT insights can also help predict which patients are most likely to experience future events, enabling clinicians to tailor care earlier with greater precision and reduce costs.” These analyses are the latest to demonstrate the prognostic power of the Heartflow One platform, the most accurate noninvasive AI-enabled CAD assessment technology, including RoadMap™ Analysis, FFRCT Analysis and Plaque Analysis. Insights from FISH&CHIPS add to a growing body of evidence demonstrating the clinical and economic value of the Heartflow One platform providing superior patient outcomes in patients with confirmed CAD.3,4 A retrospective analysis of symptomatic patients from a cohort of the FISH&CHIPS Study presented at the American Heart Association (AHA) Scientific Sessions 2025 provided strong validation of total plaque volume-based staging measured with Heartflow Plaque Analysis as a predictor of future heart attacks or cardiovascular death.5 Heartflow One provides an integrated workflow that empowers physicians to improve care by enabling a faster, more optimal diagnosis to avoid unnecessary tests. About FISH&CHIPSFISH&CHIPS, the largest FFRCT study conducted to date, is a real-world, multicenter, quasi-experimental observational clinical study designed to assess the incremental impact of adding FFRCT to a coronary CTA-first diagnostic paradigm for CAD at a national level. The study analyzed data from 27 NHS hospital sites in England, including 90,553 patients followed for at least two years. The primary objective was to determine whether introducing a coronary CTA+FFRCT diagnostic pathway was clinically useful and safe compared to a standard-of-care diagnostic chest pain pathway using coronary CTA alone. Two-year data were published in May 2025 in Nature Medicine, showing improved care efficiency with a reduction in unnecessary invasive and noninvasive cardiac tests using coronary CTA and Heartflow FFRCT versus coronary CTA alone. The study was funded by the UK Medical Research Council (MRC) and supported by the National Institute for Health and Care Research (NIHR) Research Delivery Network.

NEW ORLEANS, Nov. 09, 2025 (GLOBE NEWSWIRE) — Heartflow, Inc. (Heartflow) (Nasdaq: HTFL), the leader in AI technology for coronary artery disease (CAD), today announced late-breaking data from the FISH&CHIPS Study presented at the American Heart Association (AHA) Scientific Sessions 2025. The new data add to the robust and growing body of evidence supporting AI-powered Heartflow Plaque Analysis with Heartflow Plaque Staging* — the most clinically validated framework for actionable CAD care. The retrospective analysis, which evaluated nearly 8,000 symptomatic patients from a cohort of the FISH&CHIPS Study, represents the largest validation to date of the Heartflow Plaque Staging framework based on total plaque volume (TPV) measurement.1 Key findings include: Patients in the highest TPV stage experienced more than a 5x greater risk of major cardiovascular events compared with patients in the lowest stage (hazard ratio 5.10, p-value < 0.0001).Higher plaque volume stages were independently associated with significantly increased rates of cardiovascular death and myocardial infarction over a median 3.3 years of follow-up.Associations remained significant after adjustment for coronary stenosis, FFRCT values and cardiovascular risk factors. “This study provides strong validation of TPV-based staging measured with Heartflow Plaque Analysis as a predictor of future heart attacks or cardiovascular death,” said Timothy Fairbairn, Ph.D., principal investigator for the FISH&CHIPS study, Liverpool Heart and Chest Hospital, and Associate Professor at the University of Liverpool, UK. “The ability to accurately measure plaque will enable cardiologists to better predict which patients are most at risk above the traditional risk factors, and thus personalize treatment, in order to prevent heart attacks or death in the future.” The findings build on results from the DECIDE Registry presented at the Society of Cardiovascular Computed Tomography (SCCT) 2025 Annual Scientific Meeting in July. DECIDE data showed that Heartflow Plaque Analysis with Plaque Staging led to changes in medical management for more than half of patients, resulting in an average reduction in LDL cholesterol of 18.7 mg/dL at 90 days. These results indicate management changes guided by Heartflow Plaque Staging result in an expected 15% decrease in risk of a cardiac event.2,3,4 “We are demonstrating how AI-powered Heartflow Plaque Analysis with Heartflow Plaque Staging can fundamentally change the way we manage CAD,” said Campbell Rogers, M.D., F.A.C.C., Chief Medical Officer at Heartflow. “These latest findings show that by embedding plaque insights directly into the diagnostic pathway, we can help physicians make more confident decisions to guide personalized and precise treatment for their patients.” *Heartflow Plaque Analysis is an FDA-cleared device. Heartflow Plaque Staging is an investigational-only framework, and its safety and effectiveness have not been reviewed by the FDA.
