Abstract/OtherAbstract:
Systolic blood pressure (SBP) is an important determinant of the development and regression of left ventricular hypertrophy (LVH) in hypertensive humans. However, comparative assessments with other BP components are scarce and generally limited in size. As part of the Progetto Ipertensione Umbria Monitoraggio Ambulatoriale (PIUMA), 743 hypertensive subjects underwent echocardiography and 24-h ambulatory BP monitoring before and after an average of 3.9 years of treatment. The changes in left ventricular mass showed a significant direct association with the changes in 24-h SBP (r=0.40), diastolic blood pressure (DBP) (r=0.33) and pulse pressure (PP) (r=0.35). Weaker associations were found with the changes in clinic BP (r=0.32, 0.31 and 0.16, respectively). In a multivariate linear regression analysis, the changes in 24-h SBP were the sole independent determinants of the changes in left ventricular mass (LVM) according to the following equation: percentage changes in LVM=0.73 x (percentage changes in 24-h SBP) -0.48 (P<0.0001). For any given reduction in 24-h SBP, the reduction in LVM did not show any association with the changes in DBP and PP, either clinic or ambulatory. These data indicate that SBP is the principal determinant of LVH regression in hypertensive humans.
