  • HEADSTART-ACS study conducted in collaboration with Indonesia's National Cardiovascular Center in world's fourth most populous country, representing strategically significant market of 288 million people

  • Data analysis is underway, with results anticipated for presentation at a cardiology conference in 2027

  • With the HEADSTART-ACS and ALIGN-ACS studies, HeartBeam has clinical experience with more than 600 patients in heart attack detection, ahead of its U.S. pivotal study planned for Q1 2027

SANTA CLARA, Calif., October 21, 2026--HeartBeam, Inc. (NASDAQ: BEAT), a medical technology company focused on transforming cardiac care by providing powerful cardiac insights, today announced that the HEADSTART-ACS study, conducted at the National Cardiovascular Center Harapan Kita in Jakarta, Indonesia, has completed enrollment ahead of schedule. The study enrolled 486 patients with data analysis underway and the results anticipated to be presented at a cardiology conference in 2027.

HEADSTART-ACS is designed to evaluate the diagnostic accuracy of the HeartBeam System in detecting acute coronary syndrome (ACS), which includes heart attack. Patients presenting to the emergency department with chest pain were evaluated with both a standard 12-lead ECG and the HeartBeam 3D ECG, and results from both modalities will be compared against each patient's final diagnosis at discharge. HeartBeam's 3D ECG provides physicians with three-dimensional information about the heart's electrical activity similar to a traditional 12-lead ECG, unlike smartwatches and other wearables. The credit card-sized device requires no cables or trained technicians and is designed to deliver a clinical-grade ECG outside of traditional hospital settings, extending access to cardiac assessment wherever patients are.

Dr. Iwan Dakota, internationally recognized interventional cardiologist and Director of the National Cardiovascular Center Harapan Kita, stated, "HeartBeam's technology has the potential to save many lives. In cases of acute myocardial infarction, time to medical intervention is a critical determinant of patient survival. We welcome and strongly support the completion of this study at our hospital and look forward to its results with great interest."

Together with the 132-patient ALIGN-ACS pilot study, whose results will be presented at TCT 2026, HEADSTART-ACS brings total enrollment across HeartBeam's heart attack detection studies to more than 600 patients. This body of work gives HeartBeam significant clinical experience with its heart attack detection technology ahead of the planned initiation of its pivotal study in the U.S. in the first quarter of 2027. The HeartBeam System is not currently cleared for heart attack detection and its use in the HEADSTART-ACS and ALIGN-ACS studies is investigational.
