Systolic blood pressure and mortality.
BACKGROUND The current systolic blood-pressure threshold for hypertension treatment is 140 mm Hg for all adults. WHO and the International Society of Hypertension have proposed that normal pressure be lower than 130 mm Hg, with an optimum pressure of less than 120 mm Hg. These recommendations are based largely on the assumption that cardiovascular and overall mortality depend in a strictly incr...
متن کاملSystolic Blood Pressure Intervention Trial (SPRINT) and Target Systolic Blood Pressure in Future Hypertension Guidelines.
The Systolic Blood Pressure (SBP, mm Hg) Intervention Trial (SPRINT) showed that targeting SBP <120 mm Hg (intensive treatment, mean SBP: 121.5 mm Hg) versus <140 (standard treatment, mean SBP: 134.6 mm Hg) reduced cardiovascular events 25%. SPRINT has 2 implicit assumptions that could impact future US hypertension guidelines: (1) standard therapy controlled SBP similarly to that in adults with...
متن کاملSystolic Blood Pressure Accuracy Enhancement in the Electronic Palpation Method Using Pulse Waveform
This paper presents and evaluates some methods to improve the accuracy of systolic blood pressure measurements based on pulse waveform. A set of measurement was carried out with elderly cardiac surgery patients. The experiments comprised two to five measurements per patient, each including a one-minute follow-up, after which the cuff was slowly inflated over the systolic blood pressure. Systoli...
متن کاملStatins, central blood pressure, and blood pressure amplification.
It is well established that blood pressure (BP) differs markedly between peripheral (brachial) and central arteries (aorta).1 As the pressure wave travels distally from the heart, mean BP and diastolic BP decrease slightly (1 to 2 mm Hg), but a gradual and significant increase of systolic BP (SBP) and pulse pressure (PP) occurs. This phenomenon is called BP amplification.1 The development of co...
متن کاملA Simple Adaptive Transfer Function for Deriving the Central Blood Pressure Waveform from a Radial Blood Pressure Waveform
Generalized transfer functions (GTFs) are available to compute the more relevant central blood pressure (BP) waveform from a more easily measured radial BP waveform. However, GTFs are population averages and therefore may not adapt to variations in pulse pressure (PP) amplification (ratio of radial to central PP). A simple adaptive transfer function (ATF) was developed. First, the transfer func...
