Clinical Report: Magnetocardiography as a Diagnostic Tool for MINOCA

Overview

This case series evaluates the use of magnetocardiography (MCG) in diagnosing myocardial infarction with non-obstructive coronary arteries (MINOCA) in two patients. Despite normal ECG findings, MCG identified infarction-related waveform features.

Background

Myocardial infarction with non-obstructive coronary arteries (MINOCA) presents a diagnostic challenge, with a significant proportion of cases remaining inconclusive. Current diagnostic approaches often fail to identify the underlying causes.

Data Highlights

No numerical data or trial data were provided in the source material.

Key Findings

  • MCG can detect myocardial ischemia in patients with MINOCA, even when ECG findings are normal.
  • Both patients in the case series had elevated myocardial enzymes.
  • Cardiac catheterization confirmed no coronary artery stenosis in both cases.
  • MCG waveforms exhibited infarction-related features despite the absence of ECG-detectable infarction.
  • Cardiac magnetic resonance (CMR) further validated the diagnostic accuracy of MCG in the second case.

Clinical Implications

MCG may serve as a diagnostic tool for MINOCA in cases where traditional methods yield inconclusive results.

Conclusion

The findings from this case series indicate that MCG may be a tool in diagnosing MINOCA.
