Pulse wave analysis of the aortic pressure waveform in severe left ventricular systolic dysfunction.
BACKGROUND The effect of moderate left ventricular systolic dysfunction (LVSD) on ventricular/vascular coupling and the aortic pressure waveform (AoPW) has been well described, but the effect of severe LVSD has not. METHODS AND RESULTS We used noninvasive, high-fidelity tonometry of the radial artery and a mathematical transfer function to generate the AoPW in 25 treated patients with LVSD (m...
متن کاملSecond derivative of the finger arterial pressure waveform: an insight into dynamics of the peripheral arterial pressure pulse.
The study investigated second derivative of the finger arterial pressure waveform (SDFAP) in 120 healthy middle-aged subjects and in 24 subjects with essential hypertension. SDFAP consists of 5 sequential waves 'a'-'e'. Their normalized magnitudes (B/A, C/A, D/A, and E/A) were calculated. In multivariate regression analysis, B/A and C/A correlated only with age. D/A independently correlated wit...
متن کاملPulse waveform analysis and arterial wall properties.
Risk factors for cardiovascular disease mediate their effects by altering the structure, properties, and function of wall and endothelial components of arterial blood vessels.1 The ability to detect and monitor change in the physical properties of arteries, representative of the cumulative and integrated influence of hemodynamic, metabolic, and inflammatory stimuli in impairing arterial wall in...
متن کاملThe Patterns of the Arterial Pressure Pulse
During the past ten years there have accumulated in this laboratory a large number of records of the arterial pressure pulses taken with the Hypodermic Manometer (4). These are faithful records of the changes in the pressure of the blood in various arteries of man and of other animals. The form of the pressure pulse curve is quite variable. Some of the types are drawn roughly to scale in the fi...
متن کاملArterial stiffness, pulse pressure, and the kidney.
Classical studies indicate that the contribution of kidneys to hypertension is almost exclusively related to the association between mean arterial pressure (MAP) and vascular resistance. Recent reports including estimates of glomerular filtration rate (GFR) have shown that pulse pressure (PP) and pulse wave velocity, 2 major indices of arterial stiffness, now emerge as significant predictors of...
