“…The first and second systolic peaks were automatically identified using the fourth derivative wave as the second and third zero crossing points, respectively. Late systolic blood pressure (SBP) in the radial artery was used as an estimate of the central SBP; measurements of the central SBP estimated by the HEM-9000AI are very close to that determined following invasively recorded aortic central SBP [6]. Brachial blood pressure and heart rate were measured simultaneously in the right brachium with an oscillometric device incorporated in HEM-9000AI.…”

“…SBP2 has been shown to accurately reflect transfer functionderived aortic SBP and was used as central SBP substitute. 6,24,25 Echo-Doppler Examination of the Carotid Arteries Carotid arteries were evaluated using an SSD-3500SV (Aloka Co, Ltd, Tokyo, Japan) with a 7.5-MHz probe equipped with a continuous-flow Doppler and phase-locked echo-tracking system. Internal diameters of the common carotid artery at end-diastole (Dd) and peaksystole (Ds) were measured.…”

Background and Purpose-Arterial stiffness, a risk factor of brain small vessel diseases (SVD), causes hemodynamic changes. Mechanical stresses, circumferential wall tension (WT), and shear stress (SS) may change with arterial stiffness and be related to SVD. We investigated the associations between mechanical stresses and arterial stiffness and SVD. Methods-A total of 1296 subjects without apparent cardiovascular diseases were recruited. Brachial-to-ankle pulse wave velocity (baPWV) was measured as an arterial stiffness index. Silent lacunar infarction and deep subcortical white matter hyperintensity were evaluated as SVD indices. Circumferential WT and SS at peak systole and end diastole were measured at the common carotid artery. Second peak of systolic blood pressure was obtained from the radial waveform and used as a central systolic blood pressure substitute. Results-baPWV was associated positively with WT (P<0.0001) and negatively with SS (P=0.0007) even after correction for confounding parameters including baPWV. SVD was associated with significantly higher WT (P<0.0001) and lower SS (P<0.0001). After adjustment for confounding parameters (including baPWV), second peak of systolic blood pressure WT (odds ratio,

“…Finally, an estimate of cSBP was calculated by the pressure at the late systolic shoulder of the radial pressure waveform using linear regression. 14,15 After an overnight fasting of at least 12 hours, a venous blood sample was obtained from the forearm of each participant. Serum or plasma samples were separated within 30 minutes of collection and were stored at −80°C, which were used for measurement of fasting blood glucose and the standard 75-g oral glucose tolerance test, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides, and creatinine concentrations.…”

Abstract-This study aimed to investigate the association of noninvasive central aortic blood pressure with kidney function decline in a Chinese community-based population with normal kidney function at baseline. A total of 3153 Chinese participants from an atherosclerosis cohort were included in our analysis. The primary outcome was renal function decline defined as a drop in estimated glomerular filtration rate (eGFR) category accompanied by a ≥25% drop in eGFR from baseline; or a sustained decline in eGFR of >5 mL/min per 1.73 m 2 /y. The secondary outcomes were rapid eGFR decline (a decline in eGFR of >3 mL/min per 1.73 m 2 /y) and new incidence of chronic kidney disease. Participants were 56.6±8.5 years old, 36.0% were males, and 48.8% had hypertension. Mean (SD) baseline eGFR was 101.2±10.6 mL/min per 1.73 m 2 . After a mean 2.35-year follow-up, the incidence of renal function decline, rapid eGFR decline and chronic kidney disease were 7.3%, 19.7%, and 0.7%, respectively. In multivariate logistic-regression analyses, central and peripheral systolic blood pressure (SBP) were both independently associated with all outcomes after adjustment for various confounders. When peripheral SBP was forced into the model with central SBP simultaneously, its significant association with the 3 outcomes all disappeared; however, central SBP was still significantly related with all outcomes even after further adjusting peripheral SBP. In conclusion, central SBP is a stronger predictor compared with peripheral SBP for early kidney function decline in a Chinese communitybased population with normal kidney function at baseline.

Estimation of central aortic systolic pressure using late systolic inflection of radial artery pulse and its application to vasodilator therapy

Abstract: Noninvasive cSBP calculated with rSBP2 accorded well with aSBP measured by the invasive method. Vasodilator medication and four of five diseases did not affect this relation.
