Effective Arterial Elastance

Left ventricular hypertrophy is an independent cardiovascular risk factor. In hypertensives, the pattern of hypertrophy is influenced by central haemodynamic characteristics. Central haemodynamics may also determine physiological differences in left ventricular structure and predispose to particular responses of the left ventricle to pathological increases in load. M-mode echocardiography was used to measure left ventricular diastolic dimension and to estimate left ventricular mass index, relative wall thickness and stroke volume in 159 healthy volunteers aged between 19 and 74 years. Tonometric sphygmography was used to estimate augmentation index, central end-systolic and mean arterial blood pressure. Effective arterial elastance was calculated as the ratio of end-systolic pressure to stroke volume. Left ventricular mass index and relative wall thickness were adjusted for variation in age, sex and blood pressure before analyses. Left ventricular diastolic dimension exhibited significant inverse correlations with both effective arterial elastance (r =-0.72, P < 0.0001) and augmentation index (r =-0.23, P = 0.004). Adjusted left ventricular mass index was inversely correlated with effective arterial elastance (r =-0.35, P < 0.0001), but no correlation was observed between left ventricular mass index and augmentation index (r = 0.04). Adjusted relative wall thickness correlated with increasing effective arterial elastance (r = 0.32, P < 0.0001) and augmentation index (r = 0.18, P = 0.02). Relative wall thickness (r = 0.34, P < 0.0001), but not left ventricular mass index, correlated with age. Higher elastance and augmentation correlates with relatively smaller left ventricular cavity size but larger relative wall thickness. Age-related changes in left ventricular afterload may affect relative wall thickness more significantly than left ventricular mass index and may contribute to a particular change in left ventricular geometry with age.

Background: To investigate the association between ankle-brachial index (ABI), left ventricular hypertrophy (LVH) and left ventricular mass index (LVMI) in a general population. Patients and methods: The study population consisted of 8,246 people aged 50 years and older who participated in the baseline survey of the Dong-gu Study conducted in Korea between 2007 and 2010. Trained research technicians measured LV mass using mode M ultrasound echocardiography and ABI using an oscillometric method. Results: After adjustment for risk factors and common carotid artery intima-media thickness (CCA-IMT) and the number of plaques, higher ABIs (1.10 1.19, 1.20 - 1.29, and ≥ 1.30) were significantly and linearly associated with high LVMI (1.10 - 1.19 ABI: β, 3.33; 95 % CI, 1.72 - 4.93; 1.20 - 1.29 ABI: β, 6.51; 95 % CI, 4.02 - 9.00; ≥ 1.30 ABI: β, 14.83; 95 % CI, 6.18 - 23.48). An ABI of 1.10 - 1.19 and 1.20 - 1.29 ABI was significantly associated with LVH (1.10 - 1.19 ABI: OR, 1.35; 95 % CI, 1.19 - 1.53; 1.20 - 1.29 ABI: OR, 1.59; 95 % CI, 1.31 - 1.92) and ABI ≥ 1.30 was marginally associated with LVH (OR, 1.73; 95 % CI, 0.93 - 3.22, p = 0.078). Conclusions: After adjustment for other cardiovascular variables and CCA-IMT and the number of plaques, higher ABIs are associated with LVH and LVMI in Koreans aged 50 years and older.
