Pulse pressure amplification and risk of cardiovascular disease.
BACKGROUND Whether pulse pressure amplification (PPA) relates to established markers of cardiovascular risk is unknown. The purpose of this study was to investigate the relationship between PPA and cardiovascular risk factors and cardiovascular risk in a population-based sample of 40- to 80-year old men. METHODS A cross-sectional, single-center study was performed in 400 men aged 40-80 years....
متن کاملIntraaortic pulse pressure amplification in subjects at high coronary risk.
Peripheral (brachial) pulse pressure normally exceeds central (aortic) pulse pressure but is a less powerful predictor of cardiovascular risk. The difference between the 2 variables, called pulse pressure amplification, has never been specifically studied between the proximal and distal aorta in coronary patients. Our goal was to determine aortic pulse pressure amplification in subjects at high...
متن کاملEffect of smoking on arterial stiffness and pulse pressure amplification.
The brachial artery pressure waveform is abnormal in smokers, but the effect of smoking on the aortic pressure waveform in both smokers and nonsmokers, particularly in the younger population, is unknown. We compared the acute and chronic effects of smoking on large-artery properties in 185 healthy young smokers and nonsmokers (mean+/-SD, 22+/-5 years). We matched 41 chronic smokers for age, hei...
متن کاملCentral pressure and pulse wave amplification in the upper limb.
Central Pressure and Pulse Wave Amplification in the Upper Limb To the Editor: The important review of pulse pressure (PP) amplification1 was directed at better understanding of central (ascending aortic or carotid) pressure generated from upper limb measurements of cuff arterial pressure and pressure waveforms. One important issue, not addressed by the authors, is how 2 different noninvasive t...
متن کاملHeart rate dependency of pulse pressure amplification and arterial stiffness.
BACKGROUND Pulse pressure and aortic pulse wave velocity, measures of arterial stiffness, are both important determinants of cardiovascular risk. However, assessment of peripheral pulse pressure does not always provide a reliable measure of changes in central pulse pressure or arterial stiffness. The aim of the present study was to assess the effect of acute changes in heart rate on arterial st...
