Prognostic impact of late gadolinium enhancement by cardiac magnetic resonance imaging in patients with non-ischaemic dilated cardiomyopathy

摘要

In the past decade, cardiovascular magnetic resonance (CMR) has emerged as a powerful tool for assessment of dilated cardiomyopathy (DCM) and provided additional data that were complementary to traditional clinical parameters. Late gadolinium enhancement (LGE)-CMR technique is suggested to be useful for evaluating various cardiac diseases such as hypertrophic cardiomyopathy. Recent studies demonstrated the presence of LGE is also associated with a worse prognosis in DCM patients [4,5]. However, the sample sizes of these studies were relative small and without assessing the relationship between the location of LGE and mortality. In this cohort study, the aims were to assess the association between different pattern of LGE and mortality in patients with DCM.
