Subendocardial Involvement as an Underrecognized LGE Subtype Related to Adverse Outcomes in Hypertrophic Cardiomyopathy
View through CrossRef
In a retrospective cohort study, 497 consecutive HCM patients with LGE confirmed by cardiac MR were collected. The risk of cardiovascular events increases with per percentage increase in LGE extent in HCM patients with extensive LGE (>15%). While instead of LGE extent, the subendocardium-involved LGE pattern, an underrecognized phenotype in HCM, is related to the adverse outcomes in patients with non-extensive LGE (<15%), especially for heart failure-related outcomes. RVIP LGE is commonly seen in HCM, but this LGE location does not merit a prognostic value.
