Progress in Clinical Magnetocardiography: The Contactless Breakthrough for Noninvasive Clinical Detection of Cardiac Ischemia Now Needs Worldwide Standardization

Magnetocardiography has received regulatory recognition as a contactless, sensitive aid for physicians to diagnose or exclude myocardial ischemia in chest pain patients, with or without coronary obstruction. Such success, however, might not equate to guideline endorsement or proven clinical effectiveness. Moreover, despite its intrinsic advantages, including unrivalled contactless functional imaging of cardiac electrophysiology and a strong potential for multimodal integration with other imaging methods, its clinical adoption remains limited by the lack of internationally recognized standards and guidelines. This Perspective Review article, highlighting the viewpoints of clinical end users, is a call for urgent action to establish an interdisciplinary expert commission. This is essential for defining consensus-based standards and recommendations for the clinical use of MCG.
