摘要：

Aim: Assess the extent of low- versus high-intensity late gadolinium enhancement (LGE) in hypertrophic cardiomyopathy (HCM). Methods: Low- versus high-intensity LGE indexed volumes in 19 HCM patients were compared to 23 myocardial infarction (MI) patients. Results: Total, low-, and high-intensity LGE volumes in HCM vs. MI were 7.6 ml/m(2), 4.7, and 2.4 vs. 11.2, 2.5, and 7.1, respectively. Total LGE volume did not differ (P = .13), though low- and high-intensity did (P = .05, .004). 67% versus 26% of all LGE was low-intensity in HCM versus MI (P < .001). Conclusions: LGE in HCM is predominantly low-intensity, so a low threshold may be the most appropriate. (C) 2015 Elsevier Inc. All rights reserved.
