Heritability of central systolic pressure augmentation: a twin study.
Less than 50% of the variance in left ventricular mass is explained by conventional factors such as age, blood pressure, and body size. Genetic influences may account for part of the unexplained variance. The central (aortic) pressure augmentation index has been suggested as a noninvasive measure of pulsatile load, which is a likely determinant of left ventricular mass. We quantified the geneti...
متن کاملDaily Liquorice Consumption for Two Weeks Increases Augmentation Index and Central Systolic and Diastolic Blood Pressure
BACKGROUND Liquorice ingestion often elevates blood pressure, but the detailed haemodynamic alterations are unknown. We studied haemodynamic changes induced by liquorice consumption in 20 subjects versus 30 controls with average blood pressures of 120/68 and 116/64 mmHg, respectively. METHODS Haemodynamic variables were measured in supine position before and after two weeks of liquorice consu...
متن کاملLate systolic pressure augmentation: role of left ventricular outflow patterns.
Late systolic augmentation of the ascending aortic pressure waveform is believed to be caused by particular impedance patterns but also could be caused by particular left ventricular outflow patterns. Using a linear mathematical model of the entire human arterial tree, we derived realistic impedance patterns by altering 1) Young's modulus of the arterial wall of the individual branches, 2) peri...
متن کاملIncreased augmentation index and central systolic arterial pressure are associated with lower school and motor performance in young adolescents
Objective In adults, improper arterial function has been linked to cognitive impairment. The pulse wave velocity (PWV), augmentation index (AIx) and other vascular parameters are useful indicators of arterial health. In our study, we monitored arterial properties, body constitution, school success, and motor skills in young adolescents. We hypothesize that reduced cognitive and motor abilities ...
متن کاملThe severity of coronary artery disease evaluated by central systolic pressure and fractional diastolic pressure
BACKGROUND Central pulse pressure, pulse pressure index and fractional pulse pressure have been confirmed to be associated with increased risk of cardiovascular disease, but if the severity of cardiovascular disease, specifically for the coronary artery disease, is evaluated by central systolic pressure and fractional diastolic pressure has been not well studied. AIMS This study was designed ...
