Extracellular volume fraction (ECV) values in non-enhanced myocardium in HCM patients and controls. The group of HCM patients is subdivided into patients with focal fibrosis on LGE (HCM-LGE+) and without focal fibrosis (HCM-LGE-). Notice that solely the group of ‘hypertensive HCM’ patients shows a significantly higher ECV compared to the other groups. ECV = extracellular volume fraction. HCM = hypertrophic cardiomyopathy. LGE = late gadolinium enhancement. * p < 0.05.
