Purpose Cardiac magnetic resonance imaging (MRI) has emerged as an essential diagnostic tool in cardiology, particularly for evaluating structural and functional abnormalities in the heart. Its utility extends to various conditions, including inflammatory heart disease, cardiomyopathies (CMPs), and myocardial infarction (1, 2). In the context of sudden cardiac arrest (SCA), a significant medical emergency characterized by the abrupt cessation of heart activity, cardiac MRI offers a valuable secondary imaging modality. The primary objective of this systematic review was to assess the...
Read more Methods and materials A systematic search was conducted using the PubMed and Cochrane Library databases to identify studies published between January 2012 and January 2023. Search terms included “cardiac arrest,” “resuscitation,” “MRI,” “magnetic resonance,” and related keywords. The inclusion criteria encompassed studies focusing on cardiac MRI post-SCA in adults (≥18 years), with a minimum patient cohort of 15 individuals. Case reports and case series were excluded. Additionally, the studies needed to be written in English or German and include randomized controlled trials or...
Read more Results The systematic review included 14 studies involving a total of 1,367 patients, of whom 91.9% underwent cardiac MRI. The studies were heterogeneous in terms of design, patient demographics, and imaging protocols, which posed challenges for direct comparisons or meta-analysis. Despite these limitations, several key findings emerged: Diagnostic Value of Cardiac MRI: Cardiac MRI provided significant diagnostic insights in cases where initial imaging modalities were inconclusive. Across studies, cardiac MRI led to new or alternative diagnoses in 13% to 50% of cases....
Read more Conclusion The findings of this review underscore the pivotal role of cardiac MRI in the diagnostic and prognostic evaluation of patients following SCA. By providing detailed tissue characterization and functional assessments, cardiac MRI complements standard diagnostic pathways and informs treatment decisions. However, significant challenges remain in its clinical application. The variability in imaging protocols, timing of MRI post-SCA, and reporting standards across studies underscores the need for standardized guidelines. The heterogeneity observed in this review highlights the necessity for consensus-driven research...
