Abstract

Objectives: To our knowledge, no population study described the association of the radial and longitudinal components of left ventricular strain with blood pressure (BP) components in continuous analyses. We therefore investigated these associations in participants randomly recruited from the general population in the framework of the family-based European Project on Genes in Hypertension. Methods: In 334 participants (55.4% women; mean age, 43.6 year), using tissue Doppler imaging (TDI), we measured the end-systolic longitudinal strain (mean 20.9%) and peak systolic strain rate (1.29 s(-1)) from the basal portion of the left ventricular inferior and posterior free walls and radial stain (51.1%) and strain rate (3.40 s(-1)) of the left ventricular posterior wall. Models included in addition to covariables and confounders both SBP and DBP or both pulse pressure (PP) and mean arterial pressure (MAP). Effect sizes were expressed per 1-SD increase in BP. Results: Longitudinal strain (-0.62%; P = 0.04 and -0.64%; P = 0.007), but not strain rate, decreased with DBP and MAP. Radial strain (4.0 and -3.4%; P
