Correlation coefficients between endocardial volume (upper row) and epicardial volume (lower row) vs SBP are shown for the whole study cohort. The endocardial surface dilates in response to rising SBP except for an area that extends from the basal septum to the mid-ventricular anterior wall where hypertrophy occurs at the expense of the cavity. The epicardial surface also shows a global expansion in association with SBP but which is less marked in the lateral wall. These changes are consistent with a concentric hypertrophic response throughout the septum and anterior wall. The white isoline represents the areas within which statistical significance was reached (p-value <0.05)
