[Cardiac magnetic resonance and uremic cardiomyopathy].

Cardiovascular disease (CV) represents the main risk factor for morbidity and mortality in chronic kidney disease (CKD) patients. Large epidemiological studies have shown direct association between severity of CKD and CV event rates. Although patients with end-stage renal disease (ESRD), including dialysis ones, are at greater CV risk, cardiovascular involvement is already evident at the early stages of CKD. End-stage CKD is characterized conventional atherosclerotic risk factor but they cannot account for CV risk as reflected in high rates of sudden cardiac death, heart failure and myocardial infarction. Non-atherosclerotic processes, including left ventricular hypertrophy and fibrosis, mostly account for the excess risk of CV. Employment of cardiac magnetic resonance (CMR) in CKD has brought an improved understanding of the adverse CV changes, known as uremic cardiomyopathy. It is due to ability of cardiac magnetic resonance to provide a comprehensive non - invasive examination of cardiac structure and function, arterial function, myocardial tissue characterization (T1 mapping and inversion recovery imaging), and myocardial metabolic function (spectroscopy).
