Smartwatch 9-lead ECG vs 12-lead ECG to detect STEMI in chest pain patients

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study compares a 9-lead ECG recorded by a smartwatch with the standard 12-lead ECG to diagnose STEMI in patients presenting with chest pain. It is conducted in a real ED setting with consecutive patients assessed by on-call cardiology, alongside their usual care. The study focuses on signal quality, diagnostic concordance, and the practicality of integrating wearable ECG data into acute ACS workflows. Enrollment excludes patients with unstable conditions or certain device-related exclusions. The aim is to validate feasibility and diagnostic performance in routine clinical practice.

Why it matters

Who can join: the full rules

Inclusion Criteria:

* Patients evaluated by the on-call cardiologist for chest pain with an ischemic profile.

Exclusion Criteria:

* Patients with extreme hemodynamic instability where the additional recording would cause an ethically unacceptable delay in their treatment.
* Patients with a prior diagnosis of left bundle branch block or pacemaker-mediated pacing.
* Patients who decline participation in the registry.
