• ALIGN-ACS pilot study compared the HeartBeam 3D ECG technology to a standard 12-lead ECG for detection of acute coronary syndrome (ACS)
• Results will inform the design of HeartBeam’s planned U.S. pivotal study, building on recent FDA Breakthrough Device Designation for heart attack assessment and acceptance into FDA’s Total Product Life Cycle Advisory Program (TAP)
• HeartBeam management team will be available to meet with key opinion leaders, industry leaders, media, and analysts during TCT 2026

SANTA CLARA, Calif.--(BUSINESS WIRE)-- HeartBeam, Inc. (NASDAQ: BEAT), a medical technology company focused on transforming cardiac care by providing powerful cardiac insights, today announced that the results of the ALIGN-ACS pilot study evaluating the HeartBeam 3D ECG technology for heart attack assessment will be presented at TCT 2026, taking place at the San Diego Convention Center, October 31-November 3, 2026.

The abstract presentation titled “Detection of Acute Coronary Syndrome by a Credit Card–Sized 3-Lead Device Versus Standard 12-Lead ECG in Emergency Department Patients” will be delivered by Graham Nichol, MD, MPH, of the University of Washington on Sunday, November 1 at 1:20 PM Pacific time.

The pilot study evaluated the HeartBeam System and a standard 12-lead ECG in detecting acute coronary syndrome (ACS), of which up to 80% is diagnosed as a heart attack. The study enrolled 132 patients presenting with chest pain in the emergency department across two clinical sites in Belgrade, Serbia.

“Heart attack assessment is our top strategic priority and ALIGN-ACS is a key step in comparing our 3D ECG technology to the standard 12-lead ECG in patients with a suspected heart attack. We look forward to Dr. Nichol’s presentation of the ALIGN-ACS pilot study results at TCT 2026,” said Branislav Vajdic, PhD, Founder and President of HeartBeam. “With FDA Breakthrough Device Designation and acceptance into the FDA’s Total Product Life Cycle Advisory Program (TAP) in place, these results will help shape the design of our U.S. pivotal study which we anticipate initiating in first quarter 2027. We look forward to Dr. Nichol’s presentation and to sharing the findings.”

Members of the HeartBeam management team will be available to meet with key opinion leaders, industry leaders, media, and sell-side analysts during the event. To schedule a meeting with HeartBeam management, please contact BEAT@mzgroup.us.

About HeartBeam, Inc.

HeartBeam, Inc. (NASDAQ: BEAT) is a medical technology company dedicated to transforming the detection and monitoring of critical cardiac conditions. The Company believes it has developed the first cable-free device capable of collecting ECG signals in 3D, from three non-coplanar directions, and synthesizing the signals into a 12-lead ECG. This platform technology is designed for portable devices that can be used wherever the patient is to deliver actionable heart intelligence. Physicians will be able to identify cardiac health trends and acute conditions and direct patients to the appropriate care – all outside of a medical facility, thus redefining the future of cardiac health management. HeartBeam’s 3D ECG technology received FDA clearance for arrhythmia assessment in December 2024, and the 12-Lead ECG synthesis software received FDA clearance for arrhythmia assessment in December 2025¹. The technology is currently being studied for heart attack assessment and is considered investigational in that indication. The Company holds more than 25 issued patents related to technology enablement. For additional information, visit HeartBeam.com.

Key Terms

acute coronary syndrome medical

Acute coronary syndrome is a group of medical emergencies caused by a sudden drop in blood flow to the heart, typically presenting as a heart attack or severe, unstable chest pain. For investors it matters because changes in incidence, new treatments, devices, clinical trial results, regulatory approvals or safety concerns can quickly affect hospital costs, drug and device sales, insurer payouts and the financial outlook for companies tied to cardiovascular care—think of it like a sudden traffic jam that stops the engine and forces rerouting of resources.

12-lead ecg technical

A 12-lead ECG (electrocardiogram) is a common medical test that records the heart’s electrical activity from 12 different viewpoints using sensors on the chest and limbs—like taking a multi-angle snapshot of the heart’s rhythm and signals. It matters to investors because it is a routine tool for detecting heart problems and monitoring safety in clinical trials and product use; abnormal findings can influence regulatory decisions, trial outcomes, or a healthcare company's market value.

breakthrough device designation regulatory

A breakthrough device designation is a regulatory program that gives promising medical devices for serious or life‑threatening conditions priority support and faster review from a health authority (e.g., the U.S. FDA). Think of it as a “fast lane” or VIP pass through development and review: it can shorten time to market, lower regulatory uncertainty, and boost a company’s commercial prospects — but it is not an approval by itself.

pivotal study medical

A pivotal study is a large, definitive clinical trial designed to show whether a medical product works and is safe enough for regulators to approve and for doctors to use. Think of it as the final exam that determines whether a drug or device moves from testing into the market; its results can dramatically change a company’s approval chances, future sales prospects, and therefore its stock value.
