Study summary

The goal of this observational study is to evaluate the diagnostic performance of the HeartBeam ECG System for detection of acute coronary syndrome. The study will enroll adults who come to the emergency department with chest pain or other symptoms suggestive of ACS. Participants will take the HeartBeam ECG recording within minutes of standard 12-lead ECG.

Read the detailed description

The primary objective of the ALIGN-ACS pilot study is to obtain preliminary estimates of the diagnostic performance (sensitivity and specificity) of the HeartBeam 3-lead ECG System for detecting ACS, relative to an adjudicated gold-standard diagnosis, with the standard 12-lead ECG as comparator.

Study population

Hospital ED

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Male or female subjects 18 years of age and older.
  2. All-comers to the hospital ED with the symptoms of chest pain and an taken on admission are considered for ACS evaluation.
  3. Able and willing to sign ICF.

Exclusion criteria

Exclusion Criteria:

  1. Open chest wounds or recent (\<30 days) surgery of the chest or abdomen.
  2. Clinical conditions that, in the opinion of the Investigator, would compromise the patient's safety or ability to complete the protocol.
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

ECG (electrocardiogram)

A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.

Groups and cohorts

  • Patients presenting to the ED with symptoms suggestive of ACS

    Adults presenting to the emergency department with suspected acute coronary syndrome (ACS) are enrolled, and study recordings are obtained. HeartBeam ECG recordings are for research purposes only and will not be used for clinical decision-making. Participants undergo routine ED cardiac evaluation. Final ACS status for the study is determined independently by an adjudication team based on the totality of available clinical data.

    Diagnostic Test: ECG

Interventions

  • Diagnostic testECG

    HeartBeam 3-dimensional 3-lead ECG recording is obtained within 10 minutes of the standard 12-lead ECG in the ED, with optional paired recordings obtained if patient is admitted, at discharge and subsequent follow-ups. Recordings are for research purposes only and are not used for clinical management.

What researchers measure

Primary outcomes

  1. Sensitivity and specificity of the HeartBeam ECG for detection of ACS

    Sensitivity and specificity of the HeartBeam ECG System for detection of ACS, reported as point estimates with 95% confidence intervals, adjudicated against the gold-standard diagnosis.

    Time frame: 1 day - acute recording from ED

Other outcomes

  1. Descriptive comparison of diagnostic performance between HeartBeam 3-lead and 12-lead ECG

    Descriptive comparison of sensitivity and specificity of the 3-lead versus the standard 12-lead ECG against the adjudicated gold standard, reported with 95% confidence intervals.

    Time frame: 1 day - acute recording from ED
