Plot of circumferential endocardial and epicardial shortening and end-diastolic wall thickness (Pooled data also segregated and averaged within bins of 5-mm increments of the end-diastolic thickness). Inverse relations were observed between circumferential endocardial and epicardial shortening and end-diastolic thickeness, which were similar to the thickness–thickening relations shown in Fig 6. HCM indicates hypertrophic cardiomyopathy.
