[Clinical guideline for non-invasive imaging techniques in diagnosing adult cardiomyopathies (2024 edition)]

Cardiomyopathies encompass a spectrum of disorders characterized by alterations in cardiac structure, function, histology, and the conduction system due to myocardial cell injury, with significant variability in clinical presentation and prognosis. Despite overlapping morphological features among different types of cardiomyopathies, phenotypic similarities limit the precision of diagnosis and consequently affect the development of therapeutic strategies and prognosis assessment. Diagnosis begins with the screening of myocardial morphology and function abnormalities, primarily relying on multimodal non-invasive imaging techniques such as echocardiography, CT scans, and cardiac magnetic resonance imaging. These techniques comprehensively summarize the structural, functional, and tissue characteristics of various cardiomyopathies, highlighting differences among them. In view of the unique needs and current situation in this field in China, an expert group has jointly developed the"Clinical guideline for non-invasive imaging techniques in diagnosing adult cardiomyopathies (2024 edition)."These guidelines integrate the latest evidence, and systematically introduce the diagnosis and monitoring of cardiomyopathy, the application of non-invasive imaging techniques, and the analysis of features of cardiomyopathies, thereby to enhance the precise diagnosis of cardiomyopathy and aid in offering information for therapeutic decision-making, aiming to provide reasonable recommendations for clinicians in China.
