Heart 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...
متن کاملPulse pressure and cardiovascular mortality in normotensive and hypertensive subjects.
There is now increasing evidence that high pulse pressure, which is an indicator of large artery stiffness, is an independent risk factor for cardiovascular mortality, especially coronary mortality, in different populations. We have recently shown in a large French population that in male subjects aged 40 to 69 years, increased pulse pressure was a strong predictor of cardiovascular mortality, ...
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 کاملShort-term variability of blood pressure and heart rate in borderline and mildly hypertensive subjects.
Electrocardiogram and intra-arterial blood pressure were recorded in 96 men (aged 35 to 45 years) by the Oxford method over a 30-hour period. The study involved 33 normotensive, 29 borderline hypertensive, and 34 mildly hypertensive individuals, as assessed by the cuff method. Five-minute periods during sleep and with subjects in supine, sitting, and standing positions were extracted from the r...
متن کاملAutonomic modulation of heart rate and blood pressure in hypertensive subjects with symptoms of anxiety.
1. The influence of anxiety symptoms on autonomic nervous system cardiovascular control has never been studied in hypertensive subjects. This study was designed to verify the presence of sympathetic hyperactivity in hypertension associated with anxiety symptoms. 2. Neuroautonomic cardiovascular control was evaluated using short-time power spectral analysis of RR and arterial pressure variabilit...
