Why the study?

The study aimed to estimate the diagnostic accuracy of the VitalScan magnetocardiograph for suspected acute coronary syndrome.

Does the VitalScan magnetocardiograph accurately diagnose acute coronary syndrome in adults with suspected ACS?

Population

680 analysed adults with suspected ACS (293 training, 387 validation)

Comparison

MCG and MCG plus MACS score vs independent adjudicated reference standard

Design

Prospective cohort study

Follow-up

30-day

Discussion

Implication

Does not support MCG for ACS rule-out in practice; leaves open whether refined thresholds or populations could improve performance.

Structured PICO

Does the VitalScan magnetocardiograph accurately diagnose acute coronary syndrome in adults with suspected ACS?

Population

680 adults with suspected acute coronary syndrome (293 in training sample, 387 in validation sample), of whom 96 (14%) had confirmed ACS.

Intervention

VitalScan magnetocardiograph (MCG) alone and combined with a modified Manchester Acute Coronary Syndrome (MACS) clinical probability score.

Comparator

Reference standard of ACS determined by an independent adjudication committee based on 30-day investigations and events.

Outcome

Diagnostic accuracy (AUROC, sensitivity, specificity) for acute coronary syndrome at 30 days.

The VitalScan magnetocardiograph has poor diagnostic accuracy and is currently unable to accurately rule out acute coronary syndrome in clinical practice.
