Abstract
The aim of the study was to investigate the association of left ventricular diastolic dysfunction (LVDD) with central and peripheral hemodynamics. A total of 1599 community-based senior residents (aged â¥Â 65 years) in northern Shanghai, China, were recruited as of August 2015. Echocardiography was performed for each participant using the MyLab30 Gold CV system. According to the recommendations from the American Society of Echocardiography, the ratio of E (peak early diastolic transmitral flow velocity) to Eâ² (early diastolic lateral mitral annulus velocity) was assessed for the evaluation of LVDD. Central blood pressure (BP) components were measured using the SphygmoCor system. In community older population (72.7 ± 6.01 years), brachial systolic BP (mm Hg) was higher than central systolic BP (141.9 ± 19.5 vs. 130.3 ± 20.1 mm Hg). A total of 214 subjects (13.4%) showed LVDD, and female showed higher prevalence of diastolic dysfunction than male (17.3% vs. 8.4%, P < .01). After adjustment for confounding variables, only central systolic BP, not brachial systolic BP, was significantly associated with E/Eâ² in the total population. Similar result was found in the subgroup analysis (participants without antihypertensive agents treatment, man, woman). Similar findings were obtained for the pulse pressure (PP) analysis. Within central hemodynamics, only central PP, but not central systolic BP or augmentation pressure, was significantly associated with E/Eâ² after adjustment. When LVDD was defined by E/Eâ² and other echocardiographic parameters, our findings remained unaltered in the multivariate logistic regression with similar adjustment in the total population and subgroup analysis. In the Chinese elderly cohort, central hemodynamics, especially central PP, is superior to other BP components in identifying LVDD (NCT02368938).
