Sex-related differences in the variability of vascular blood flow in middle-age individuals.
Analysis of spectral parameters of vascular blood flow variability revealed some sex-related peculiarities. The amplitude of aortic pulsation and total variability power of this parameter and its four components (ultralow frequency, very low frequency, low frequency, and high frequency range) were higher in women. The amplitude of microvascular pulsation and total variability power of this parameter and components were higher in men. In male patients, the relative variability power for the amplitude of microvascular pulsation was higher in the high frequency and low frequency ranges, but lower in the very low frequency and ultralow frequency ranges.
