Magnetocardiography (MCG) is a highly sensitive, non-invasive, and functional imaging technique that records and examines magnetic fields generated by the electrical activity of the heart to reflect cardiac electrophysiological changes, including the first superconducting quantum interference device and optically pumped magnetometers-MCG. The 60-year research process yields new understanding in the areas of signal extraction, processing, and clinical application for the detection and treatment of cardiac diseases. Especially, the significant advancements in magnetic sensor technology, preprocessing methods and denoising methods have promoted the development of MCG. This article systematically reviews 83 studies to provide the latest and general overview of MCG in acute chest pain (6 studies), acute coronary syndrome (10 studies), ischemic heart disease (13 studies), non-ischemic cardiomyopathies (3 studies), arrhythmia (9 studies), and fetal congenital arrhythmia (11 studies). We highlight its incremental value in the triage of acute chest pain, diagnosis and prognosis prediction of chronic and acute coronary syndromes. We also discuss the limitations of this field and directions of future development.

1 Introduction

Local currents are produced by depolarization, repolarization, and ion transmembrane mobility in cells. The electrophysiological activity of cells will produce weak magnetic signals, which are strongest in excitable cells, including myocardial and nerve cells. Magnetocardiography (MCG) can detect alterations in the magnetic fields induced by abnormal electrical activity in the heart through magnetically shielded or unshielded superconducting quantum interference device (SQUID) systems, optically pumped magnetometers (OPM), or portable miniaturized induction coils (1). Compared to electrocardiogram (ECG), which obtains electrical signals and current conventional imaging detection methods, MCG provides additional information for disease diagnosis through changes in magnetic signals and has unique advantages. First, MCG is not affected by the thickness of the pericardium or chest wall, providing more accurate information through its multi-channel array (2). In addition, MCG has a greater spatiotemporal resolution and is sensitive to the magnetic field produced by tangential current, which can simultaneously collect tangential and eddy currents in the subepicardial and deep myocardium (35).

Recent decades have seen numerous studies on signal processing and clinical applications of MCG. Several studies have concluded that MCG is more sensitive to triage of acute chest pain and diagnosis of ischemic heart disease (IHD) than widely used screening tools such as ECG, echocardiography (ECHO), and stress tests (68). Additionally, increasing research has linked MCG to fetal heart disease, myocardial inflammation, and arrhythmia. As an exceptionally sensitive, non-contact, non-invasive, and radiation-free examination method, MCG has potential clinical value. Therefore, we aimed to comprehensively summarize the literature on the clinical application of MCG and provide updated data.

2 Methods

In this review, we conducted an extensive electronic search of all English-language studies published before Oct 31, 2024, from the PubMed, Web of Science, EMBASE, and Cochrane Library databases. We used the following search terms: “magnetocardiography” AND (“heart disease” OR “cardiac disease” OR “fetal disease” OR “clinical” OR “chest pain” OR “coronary syndrome” OR “arrhythmia” OR “cardiomyopathy”). After removing books, editorials, case reports, letters and duplicates, we included studies that reported MCG in cardiac diseases. Furthermore, references cited in the included publications were examined to identify additional relevant articles. Finally, 83 studies published between January 1971 and October 2024 were included in this review.

3 Results

3.1 Magnetocardiography

The MCG technology has been developed for nearly 60 years. In 1970, MCG based on a SQUID was created (9). This magnetic detector offered high sensitivity, a wide measurement range, and a broad frequency band, significantly enhancing the spatial accuracy and signal-to-noise ratio (9). In the past 60 years, the development of multichannel sensors, unshielded SQUID systems, and the emergence of OPM have contributed to the advancement of MCG. While SQUID have been the primary tool for clinical research, OPM are being explored for their potential in making MCG more accessible. In 1991, Fenici et al. developed non-magnetic catheter technology based on 10 years of practical experience in MCG and successfully achieved arrhythmia localization through a single-channel system, laying early evidence for the clinical research and application of MCG (10).

At present, there is still no standardized MCG consensus or database to define the parameters of one-dimensional butterfly diagram (BFD), two-dimensional magnetic field map and current density map in MCG. Several scholars have recorded commonly utilized parameters of one-dimensional and multi-dimensional MCG, including interval duration, waveform, dipole phenomenon, and vector parameters, and have identified significant sex-based and age-related differences in amplitude and repolarization angle parameters (11, 12).

3.2 Rapid triage and mortality prediction of acute chest pain

Acute chest pain (ACP) continues a prevalent complaint in emergency and internal medicine, with over 7 million annual visits, of which 20%–40% are non-cardiac (13, 14). As a heterogeneous group of diseases, accurate and expeditious recognition of acute coronary syndrome (ACS), acute pulmonary embolism, aortic dissection, and other high-risk ACP conditions represents the primary focus and challenge in the emergency management of ACP. There is a lack of sensitive, convenient and rapid stratification methods to reduce the risk of misdiagnosis. Same as avoiding unnecessary invasive tests and minimizing patient loss.

Previous studies have investigated the utility of MCG in triaging patients with ACP (Table 1). Compared to conventional diagnostic tools (ECG, troponin I, and ECHO) at admission, MCG exhibited superior performance in identifying ACS and IHD through multiple MCG parameters including the angle, intensity, shape, and additional characteristics of the current or magnetic dipole vector during repolarization (68). Pena et al. developed a novel imaging and analysis system to transform MCG data into dynamic 90-second images to evaluate non-high-risk ACP patients in the emergency observation unit, its specificity (78.3%) and negative predictive value (NPV, 92.3%) suggested potential utility in safely ruling out critical ischemia and guiding discharge decisions (15). Ghasemi-Roudsari et al. further explored a portable MCG and built a diagnostic prediction model for ACP patients by logistic regression analysis of 10 key parameters derived from QR and RS segments in magnetic field map (MFM) and current density map (CDM), but the model showed limited accuracy in differentiating IHD among ACP patients (16). Beyond diagnosis, MCG parameters showed strong prognostic significance. Two MCG parameters of QTc prolongation and low repolarization reserve and one clinical parameter of elevated serum creatinine were indicators of long-term mortality in ACP patients (P < 0.05), achieving 90.9% sensitivity, 85.6% specificity, and 99.4% NPV for cardiac death (17). Patients with abnormal MCG findings faced a nine-fold increased risk of cardiac death (17).

3.3 Acute coronary syndrome

ACS constitutes a continuous spectrum of life-threatening conditions initiated by coronary atherosclerotic plaque rupture and subsequent thrombotic occlusion, encompassing ST-elevation myocardial infarction (STEMI) and non-ST-elevation ACS (NSTE-ACS) (18). Characterized by high prevalence, sudden onset, and significant mortality, ACS requires urgent diagnosis to minimize the duration of emergency stay, as acute ischemia leads to irreversible myocardial cell necrosis. Currently, NSTE-ACS often lacks specific changes in ECG and myocardial damage indicators, requiring continuous testing for diagnosis. There is a pressing need for more efficient methods to facilitate early detection and risk stratification.

We compiled a comprehensive list of ACS articles pertaining to MCG (Table 2). In ACS, four qualitative and quantitative parameters including magnitude, angle, perimeter and area of MFM, as well as the T-wave CDM, exhibited marked abnormalities; T-peak maximum current angle and magnetic field angle had the highest sensitivity (96.4%), correlating positively with the severity of myocardial infarction (1922). Among them, the integrated maximum CDM provided spatiotemporal information of ventricular repolarization process, with higher sensitivity (91.2%) and specificity (84.6%) for identifying STEMI than the integrated equivalent current dipole method (sensitivity, 84.3%; specificity, 82.1%) (19). ACS consistently exhibits non-dipole phenomena in MFM, with coherence impacted particularly during repolarization, the relationship of depolarization parameters and ACS was weak (23, 24). In 70% of unstable angina (UA) and 92.5% of non-ST-elevation myocardial infarction (NSTEMI), NSTE-ACS manifested as abnormal dipole position and shape, and was positively correlated with the severity of coronary artery stenosis (20).

Table 2
www.frontiersin.org

Table 2. Studies of the diagnostic value of MCG in ACS.

MCG also demonstrated predictive capacity for clinical outcomes. Bang et al. illustrated that non-dipole phenomenon of T-peak independently predicted major adverse cardiac events, including all-cause death, reinfarction, and percutaneous coronary intervention (hazard ratio = 2.89, 95% confidence interval: 1.20–6.97, P = 0.02) (25). A three-year follow-up study of NSTEMI patients revealed that MCG outperformed troponin I, ECHO, and ECG in mortality prediction (relative risk: 4.58 vs. 2.48 vs. 1.58 vs. 1.69), with abnormal MCG independently portending poor prognosis (7, 26).

It can be seen that MFM and CDM during the repolarization phase have application prospects for both diagnosis and prognostic prediction in ACS. Future research requires further quantification of MFM and CDM parameters to establish a unified standard. Additionally, MCG has only been exclusively detected after the treatment of acute myocardial infarction, and point-of-care device reliability has not yet been fully validated (27). Further investigations are warranted to examine the feasibility of early detection in the post-event period.

3.4 Detection and classification of ischemic heart disease

IHD arises from a disparity between coronary blood supply and myocardial oxygen demand, caused by coronary spasm, stenosis, or obstruction, which ultimately leads to myocardial hypoxia or necrosis. IHD manifests as angina, myocardial infarction or even sudden cardiac death clinically. As a major global health concern, IHD affects 18.2 million cases in the United States alone and remains the leading cause of death worldwide, with 9.24 million global deaths attributed to IHD in 2022, representing 80% of sudden cardiac fatalities and 34% of cardiovascular disease-related deaths under before aged 70 (2830). The heterogeneous clinical presentations and complex differential diagnosis of IHD pose significant challenges in developing rapid and accurate methods for case identification and risk stratification.

ECG and ECHO serve as first-line screening tools for IHD detection. A meta-analysis of 147 studies involving 24,074 patients reported a sensitivity of 68% and specificity of 77% for ECG stress tests (31). Coronary computed tomography angiography (CCTA) offers a high diagnostic accuracy in assessing anatomic coronary stenosis, with a sensitivity of 94%, specificity of 83%, and NPV of 99% (32, 33). However, its poor positive predictive value (PPV) (48%–64%) and inability to reliably evaluate hemodynamic changes or screen large-scale population necessitate additional supplementary testing to determine ischemia severity (33, 34). Existing non-invasive functional tests use perfusion imaging with radioactive tracers to evaluate myocardial viability, though these methods carry inherent risks of radiation exposure and potential adverse effects. In contrast, MCG demonstrates promising diagnostic performance. Three studies have shown that abnormal ST-segment and T-wave in MCG during myocardial ischemia can be correctly classified in 80% of cases using only one parameter (sA4), irrespective of the number or location of affected vessels, when combining all three parameters achieved 84% sensitivity and 83% specificity (area under the curve, AUC: 0.912) (3, 35). Comparative analyses revealed that MCG exhibited greater mean differences in QRS complex, T-wave, and ST-segment abnormalities than ECG (37% vs. 26%) (36).

We visually listed the literature on the diagnostic value of MCG for coronary stenosis in Table 3. Whether at rest or under stress testing, MCG demonstrated superior efficacy than ECG in identifying chronic coronary disease (CCD), regardless of whether recordings were obtained in magnetically shielded or unshielded environments (3740). Additionally, QTc parameters of MCG successfully screened CCD patients at rest, providing a viable alternative for individuals unable to tolerate stress testing (41). Machine learning-based MCG diagnostic models have achieved high sensitivity (82.6%–91.3%) in detecting myocardial ischemia, though specificity remains modest (10.0%–50.0%) (42). For borderline coronary lesions (40%–90% stenosis), MCG yielded an AUC of 0.864 (95% CI: 0.803–0.925), suggesting its potential to reduce unnecessary invasive procedures (43).

Table 3
www.frontiersin.org

Table 3. Studies of the diagnostic value of MCG in CCD.

Different MCG parameters and analytical approaches have been explored to optimize coronary stenosis detection in suspected CCD patients. The combination of ST-segment fluctuation score and qualitative non-dipole parameter achieved the highest diagnostic accuracy (AUC: 0.93) (39, 44, 45). In chronic chest pain patients with normal ECG, magnetic field map and angles distinguished coronary stenosis with 90.9% sensitivity and 94.1% specificity (46). CDM during ST-T interval effectively differentiated healthy individuals from CCD patients, though their ability to distinguish non-CCD from CCD cases was inferior to MFM (47). Integrating one-dimensional BFD with MFM enhanced diagnostic performance and localized stenosis with 69%–77% accuracy (4850). To expedite data processing and minimize manual errors, automated machine learning approaches are applied for parameter extraction and analysis. Bayesian neural networks and multilayer perceptron demonstrated high sensitivity, making them suitable for high-risk population screening (5154). A hybrid classifier Support Vector Machine-eXtreme Gradient Boosting, incorporating 164T-wave features (time domain, frequency domain, and information theory characteristics), achieved exceptional performance (AUC, 0.98; specificity, 94.0%) while effectively reducing false positives (55). In summary, MCG showed particular strengths in identifying ischemia in resting patients and those with borderline lesions. Individual parameters in MFM and CDM as well as the complex index in BFD are all strong predictors, AI-enhanced approaches further improved diagnostic accuracy. Notably, MCG also showed acceptable potential for detecting non-obstructive coronary microvascular dysfunction (sensitivity: 68%, specificity: 65%) (56).

It is important to emphasize that all aforementioned studies were conducted on patients with CCD, indicating that MCG can detect lesions with coronary stenosis of ≥70%. However, for vascular stenosis that has not yet affected the structure or function of cells, it does not cause abnormal conduction or magnetic signals, MCG will be unable to detect it. In addition, the relationship between the degree of coronary stenosis and changes in magnetocardiographic vector has not yet been standardized, so the current evidence supporting magnetocardiographic evaluation in this context remains limited and can not contribute to clinical decision-making.

3.5 Non-ischemic cardiomyopathies

Beyond IHD, a spectrum of cardiac disorders arising from genetic predisposition, metabolic dysfunction, and structural myocardial changes are collectively termed non-ischemic cardiomyopathies (57). Integrating more dimensions to achieve precise classification of cardiomyopathies is a way forward for efficient diagnosis and treatment. Emerging research have investigated the promising role of MCG in the diagnosis, treatment monitoring, and recurrence prediction of non-ischemic cardiomyopathies.

Changes of magnetic vector (the value ≥ 0.051) discriminated cardiomyopathy from controls with 59% sensitivity, 95% specificity, 93% PPV, and 64% NPV, and reflected immune-suppressive therapeutic effect earlier than ECHO (7 vs. 30 days) (58). In dilated cardiomyopathy, MCG effectively predicted major adverse cardiac events (MACE) by detecting left intraventricular disorganized conduction (LIDC) with high spatiotemporal resolution to facilitate risk stratification, and the predictive value of LIDC was superior to that of traditional ECG indices such as fragmented QRS waves and late potential (59). By capturing early changes of myocardial electrical remodeling and quantifying the Kullback Leibler (KL) entropy of the cardiac magnetic field topology, MCG differentiated hypertrophic cardiomyopathy from healthy individuals or cardiac hypertrophy caused by other reasons, and the accuracy increased to 87.9% when combined with regional magnetic field strength parameters (sensitivity from 78.8% to 84.8% and specificity from 86.9% to 88.9%), and identified all patients with hypertrophic cardiomyopathy carrying genetic mutation in familial screening (60).

3.6 Diagnosis and localization of arrhythmia

Compared to ECG, MCG has a enhanced spatial resolution of cardiac current distribution and more comprehensive insights into ventricular depolarization and repolarization. As summarized in Table 4, growing evidence supports the utility of MCG in risk stratification, original localization, and management guidance.

Table 4
www.frontiersin.org

Table 4. Studies of the diagnostic value of MCG in cardiac arrhythmia.

There was no statistical difference in ECG parameters between benign and malignant early repolarization patterns (ERP). Conversely, ERP-ventricular fibrillation (ERP-VF) patients in MCG had prolonged QRS complex (108 ± 24 vs. 91 ± 23 ms, P = 0.02) and diminished root-mean-square voltage of the last 40 ms (0.10 ± 0.08 vs. 0.25 ± 0.20, P = 0.01) (61). In addition, compared with invasive electrophysiological mapping, the accuracy of MCG in differentiating benign and malignant ventricular arrhythmia was 94.7% (62). Beyond non-invasive risk stratification for VF, the low-amplitude QRS complex also predicted arrhythmia risk after MI, with QRS duration > 121 ms as an independent predictor (63, 64). The P-wave duration, PR interval and P-wave depolarization of patients with atrial fibrillation were significantly longer than those of healthy controls, providing more sensitive atrial fibrillation susceptibility markers than ECG, the angle dynamics of P-wave depolarization was an independent predictor of AF recurrence (P = 0.037) (65). The alteration in left atrial pseudo-current conversion detected left atrial dysfunction in paroxysmal atrial fibrillation, and identify different atrial conduction pathways (such as Bachmann bundles, margin of fossa ovalis, and coronary sinus ostial region) with an accuracy of 93%, providing a new perspective for the mechanism study of atrial fibrillation (66, 67).

The multi-channel sensors of MCG provide insights into the temporal and spatial distribution of cardiac magnetic fields and enable the localization of arrhythmia origins through three-dimensional imaging. Ito et al. developed a new spatial filter to differentiate ventricular arrhythmia originating from the right ventricular outflow tract and the aortic sinus cusp, through three parameters, with depth being the most powerful predictor (68). By integrating cardiac computed tomography to reconstruct the 3-D current distribution, the origin of premature ventricular complexes throughout the ventricle was pinpointed with 94% accuracy (17/18) (69).

3.7 Fetal magnetocardiography

Current evaluation of fetal cardiac structure and function relies on cardiotocography and ECHO, but they lack electrophysiological data on the conduction system and cannot identify certain malignant arrhythmia such as torsade de pointes (70). Fetal MCG (fMCG) allows for precise assessment of cardiac time intervals, signal characteristics, and various rhythm patterns by extracting fetal cardiac magnetic signals after the 15 weeks of pregnancy (7174). It provides vital information about fetal cardiac development and function, as shown in Table 5.

Table 5
www.frontiersin.org

Table 5. Studies of the diagnostic value of fMCG.

Both the 2014 and 2024 American Heart Association scientific statements advocated fMCG to assess cardiac conduction and rhythm abnormalities in fetuses with suspected or confirmed congenital heart disease (Class 2a) (75, 76). Strand et al. used SQUID to characterize fMCG waveforms of 132 healthy fetuses at 15.7–39.9 weeks of gestation, P-wave, PR-interval, QRS complex, and RR interval increased with gestational age (P < 0.001), while QT-interval and QTc (QTc = QT/RR1/2) remained constant throughout gestation (73). In contrast, another study used new magnetograph dedicated to fetal recordings and concluded that P wave, QRS complex, ST-segment, QT-interval and QTc increased with gestational age, PQ segment and T-wave were independent of gestation (77). It is imperative to elucidate the waveform characteristics of fetuses at different developmental stages.

Wacker-Gussmann et al. reviewed 144 fetuses with tachycardia, bradycardia atrioventricular block (AVB), or familial Long QT syndrome (LQTS) (71). As a result, fMCG facilitated additional diagnoses in 81% (117/144) of cases, with 56% (81/144) exhibiting critical alterations, prompting a change in the treatment regimen for 35 patients (71). LQTS is a hereditary ion channel disorder that leads to potentially fatal heart rhythm abnormalities and accounts for 10% of sudden infant death and unexplained stillbirths (78). Early detection of abnormal heart rates and intrauterine treatment can reduce mortality. Research published in Circulation in 2013 showed that QTc > 490 ms, corroborated by genetic testing, achieved 89% sensitivity and specificity for LQTS between 19 and 38 weeks of gestation, with QTc ≥ 620 ms predicting a severe TdP phenotype, characterized by various uncommon rhythms such as second-degree AVB, T-wave alternation, and QRS alternation (79).

The waveform characteristics of AVB with different degrees of severity are much more complex than those of ECHO. Fetuses with positive maternal SSA/Ro SSB/La antibodies are at elevated risk of developing immune AVB. The prolonged PQ segment predicts early atrioventricular node involvement in fetuses (60.2 ms vs. 50.8 ms; P < 0.001) (80). Different waveforms classified AVB and accurately identified third-degree AVB with structural heart disease and poor prognosis (81, 82). ECHO struggled to distinguish blocked atrial bigeminy (BAB) from 2nd degree AVB, despite their divergent clinical management and prognosis (83). fMCG discerned differences between the two entities, with the ectopic P wave (P’) manifesting earlier and a higher heart rate observed in BAB cases, thus offering pivotal evidence for differential diagnosis (83).

4 Limitations

Although many studies have proved that MCG has excellent clinical diagnostic and prognostic predictive capabilities across various cardiac diseases and is a promising clinical tool in the future, certain limitations persist within this domain. First, there exists heterogeneity in study design, and parameters, with different methodologies, MCG systems, and analytical parameters employed across studies. The absence of standardized protocols in the acquisition of cardiomagnetic images and data, as well as in parameter definitions and diagnostic thresholds constrains the general applicability and clinical advancement of research findings. Establishing uniform guidelines for MCG interpretation is crucial for advancing the field. Secondly, most clinical studies of MCG are conducted in single-center with small cohorts and meticulously screened populations. This may introduce selection bias and lead to an overestimation of diagnostic accuracy. Consequently, larger, multi-center studies are necessary to validate the reproducibility of MCG across diverse populations, devoid of established clinical backgrounds and in varied environments. Finally, research evidence concerning non-ischemic cardiomyopathy and UA is limited, and there are few studies on MCG parameters and long-term prognosis verification, thereby limiting the robustness of MCG results. Therefore, future research must focus on optimizing the standardization of MCG data collection processes, establishing unified parameter reference ranges, and identifying specific parameters for various diseases.

5 Conclusion

Magnetocardiography provides a new perspective for the rapid and non-invasive identification of critical and severe heart diseases. The high spatial and temporal resolution and absence of interference from human tissue with the magnetic signal confer excellent functional imaging capabilities to MCG, demonstrating superior diagnostic performance for adult and fetal heart disease, including MI, adult and fetal arrhythmia, and rapid triage of ACP. However, its application is still limited to a few research centers, and the lack of uniform equipment standards and specifications makes it difficult to directly compare the results between different devices. Furthermore, there remains a paucity of large-scale clinical evidence and well-defined diagnostic criteria for MCG.

Future research should focus on validating parameters, establishing usage standards, and integrating MCG into clinical practice to develop high-performance devices suitable for routine environments, ensuring the rapid and accurate diagnosis of acute and severe heart diseases.
