Central blood pressure
Central aortic systolic blood pressure (cSBP) differs from peripheral systolic blood pressure (pSBP) measured in the arm. cSBP may be estimated non-invasively by application of a generalised transfer function (GIF) to a high fidelity peripheral arterial waveform or from the late systolic shoulder …

Exploring circadian blood pressure patterns
… of the importance of reducing mean levels of blood pressure (BP), we are less informed about the benefits of reducing other parameters of BP, specifically BP variability (BPV). Ambulatory blood pressure monitoring (ABPM), which can be used to obtain estimates of BP over a 24h period, offers a …

Arterial blood pressure estimation using ultrasound
While blood pressure is commonly used by doctors as an indicator of patient health, the available techniques to measure the quantity suffer from many inconveniences such as cutting off blood flow, being cumbersome to use, being invasive, or being inaccurate. The research addresses many of these …

Association of Blood Pressure and Gait Speed in Hypertensive Older Adults: The Systolic Blood Pressure Intervention Trial (SPRINT)
… of this study was to examine the association of blood pressure measures and mobility assessed by gait speed in hypertensive older adults.

Accurate Measurement of Blood Pressure in Pregnancy
… in the UK and worldwide. Accurate recording of blood pressure measurement (BPM) is critical to ensure hypertension in pregnancy is correctly diagnosed and managed. Defective equipment and a failure to follow the correct BPM technique can lead to inaccurate readings. Studies have found this to be …

Investigation of slow oscillations in blood pressure
This thesis addresses blood pressure regulation from a mathematical modelling perspective. Blood pressure is controlled via a number of different negative feedback mechanisms. The baroreflex loop is the most dominant of these mechanisms for short-term control of blood pressure, and soft-limiting …

Ambulatory blood pressure monitoring in hypertensive pregnancies
… in pregnancy, and the role of ambulatory blood pressure monitoring (ABPM). Overviews of blood pressure measurement and hypertension in pregnancy are followed by discussion of ABPM in non-pregnant and pregnant individuals. A literature review of research in ABPM in pregnancy is presented, …

EXERCISE BLOOD PRESSURE IN ADOLESCENCE AND BLOOD PRESSURE FIVE YEARS LATER IN PERSONS BORN WITH VERY LOW BIRTH WEIGHT
… or minimize end-organ damage. Although resting blood pressure (BP) is found to be a good predictor of future resting BP, the addition of BP response to an exercise stressor may further enhance the ability to predict future levels of resting BP in both adolescents and young adults. PURPOSE: To …

Blood Pressure, Arterial Stiffness and Cardiovascular Risk Prediction
… threshold for hypertension from a systolic blood pressure (BP) of 140mmHg to 130mmHg in line with the US guidelines as recommended by the AHA/ACC. This would dramatically increase the number of adults requiring drug therapy. Aortic stiffness is an attractive novel biomarker, particularly for …

Cardiac output estimation using arterial blood pressure waveforms
… could be estimated by analysis of the arterial blood pressure (ABP) waveform has captured the attention of many investigators. This approach of estimating CO is minimally invasive, cheap, and can be done continuously as long as ABP waveforms are available. Over a dozen different methods of …

SNP Interactions in the Genetic Architecture of Blood Pressure
… genetic component to the regulation of blood pressure: BP) but most BP variance remains unattributed to specific genetic variants. Candidate gene studies show linkage to rare Mendelian disorders but inconsistent association with BP. Massive consortia of genome-wide association studies …

Vitamin D, Calcium and Blood Pressure in the U.S.
… 1,25-hydroxyvitamin D (25[OH]D), may influence blood pressure by increasing gastrointestinal calcium absorption. The objectives of this study were to first examine the association between blood pressure and blood serum 25(OH)D levels, and then explore the interaction between 25(OH)D, calcium …
