Cardiomyopathies are diseases of cardiomyocytes or different heart structures which are manifested through changes in morphology or function of the heart. Due to relatively non-negligible prevalence and clinical course, cardiomyopathies are significant public health burden in terms of increased utilization of medical services, impairing quality of life, as well as mortality. In the last decades, cardiac magnetic resonance (CMR) became important clinical tool in management of patients with non-ischemic cardiomyopathy (NICMP). CMR offers virtue of non-invasive 3D imaging of cardiac structures and function, and owing the advances in technology, there is a relatively constant pace of improvements in spatial, temporal resolutions, as well as tissue characterization. For these reasons use of CMR increases in every day clinical practice and growing number of centers is available. CMR brings diagnostic and prognostic advances in managed care of patients with cardiomyopathies, with ability to influence course of treatment and the most important increase survival of patients. Typical complications within the course of NICMP like development of heart failure, malignant arrhythmia and cardiac death could be verified, in part foreseen, and to different degree ameliorated by use of CMR. (1, 2) This lecture will present the most important issues around utilization of CMR in clinical management of patients with non-ischemic cardiomyopathies.
