Development and validation of a clinical diagnostic model for myocardial ischaemia in borderline coronary lesions based on optical pumped magnetometer magnetocardiography: a prospective observational cohort study.

ABSTRACT:

Objectives

To develop and validate a clinical diagnostic model based on optical pumped magnetometer magnetocardiography (OPM-MCG) for the detection of myocardial ischaemia in patients with borderline coronary lesions prior to invasive coronary angiography (ICA).

Design

Prospective observational cohort study.

Setting

Single centre of the China National Clinical Research Centre for Cardiovascular Disease (NCCMRC).

Participants

Adults with borderline coronary lesions on ICA (n=141).

Interventions

Underwent OPM-MCG before ICA and fractional flow reserve measurement.

Results

Five parameters were included in the final diagnostic model: MAg_max-TT, δDt_sum-PN, δAg_sum-C, δAr_sum-N and δAr_min-N. 1000 boot
