HeartBeam Completes Enrollment in Heart Attack Detection Pilot Study Ahead of Schedule

(Moderate)

(Very Positive)

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 medical

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.

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.

fda submission regulatory

A FDA submission is a formal packet of scientific evidence and paperwork a company sends to the U.S. Food and Drug Administration to seek permission to sell a drug, biologic, medical device or related product. Think of it like applying for a building permit: the company must show the product is safe and works as claimed before it can go to market. Investors care because the FDA’s decision governs whether and when a product can generate revenue, and the timing and outcome often move a company’s valuation.

Accelerated enrollment completion in ALIGN-ASS study underscores HeartBeam’s execution on its key strategic priority of heart attack detection
Data analysis is underway, with full results anticipated for presentation at upcoming cardiology conference
Findings will inform the design of the planned U.S. pivotal study and support the FDA pathway
Future indication expansion could unlock a large addressable market of millions of patients at risk

SANTA CLARA, Calif.--(BUSINESS WIRE)--

HeartBeam, Inc. (NASDAQ: BEAT), a medical technology company focused on transforming cardiac care through powerful cardiac insights, today announced completion of patient enrollment in its ALIGN-ACS pilot study evaluating the HeartBeam System for heart attack detection. Enrollment was completed ahead of the Company’s previously communicated third quarter 2026 timeline.

Heart attacks remain a leading cause of death in the United States, with millions of patients at elevated risk. Patients with heart attack symptoms often delay seeking care for more than 2 hours¹ because the symptoms can be vague or subtle, which contributes to higher mortality, more complications, and greater care costs. HeartBeam’s 3D ECG technology is designed to allow patients to record a clinical-grade ECG at the onset of symptoms, wherever they are, with the goal of shortening symptom-to-door times and supporting faster, more informed care decisions outside a clinical setting.

“Completing enrollment ahead of schedule reflects both the quality of the study design and the operational discipline our team has built, providing us a strong foundation as we move into pivotal study planning,” said Branislav Vajdic, Ph.D., Founder and President of HeartBeam. “We believe the data from the ALIGN-ACS pilot study will be an important input into our discussions with the FDA, and we are evaluating whether this milestone supports a more accelerated path toward an expanded indication for heart attack detection. We look forward to sharing full results later this year and advancing this program with the same discipline and pace our team has demonstrated throughout this study.”

The study enrolled 120 patients presenting with chest pain in the emergency department across two clinical sites in Belgrade, Serbia. Patients were evaluated with both a standard 12-lead ECG and the HeartBeam System, with physician assessment for acute coronary syndrome using both ECG modalities compared against an independently adjudicated clinical-data-based gold standard. Data analysis is underway, and the Company plans to present the results at a major cardiology conference in the coming months.

Results from the ALIGN-ACS pilot study are intended to inform the design of a planned pivotal study in the United States and support a future FDA submission seeking to expand the HeartBeam System’s indication beyond arrhythmia assessment to include heart attack assessment. The Company plans to use learnings from the pilot, together with prior proof-of-concept data, including a study recently published in JACC: Advances, to inform upcoming discussions with the FDA regarding the design and scope of the pivotal program.

This milestone reinforces HeartBeam’s focus on its path toward an expanded indication for heart attack detection and its broader platform strategy. The Company’s long-term vision is to make its potentially life-changing system available to as many patients as possible, as quickly as possible.

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 has developed the first-ever 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 2025**. The Company holds over 20 issued patents related to technology enablement. For additional information, visit HeartBeam.com.
