Insights
Atherosclerosis significantly impacts major head arteries (MHA) circulation in men aged 40-65. Most men showed abnormal circulation or stenosis, highlighting the prevalence of vascular disease in this demographic.
Area of Science:
- Vascular Medicine and Atherosclerosis Research
- Diagnostic Ultrasound and Hemodynamics
Background:
- Atherosclerosis is a prevalent vascular disease affecting major head arteries (MHA).
- Hemodynamic changes in MHA can indicate underlying vascular health issues.
- Early detection of MHA stenosis is crucial for managing cerebrovascular risk.
Purpose of the Study:
- To compare the frequency and severity of hemodynamic changes in MHA.
- To investigate atherosclerosis-related changes in subjects with and without vascular diseases.
- To assess MHA stenosis prevalence in a male population aged 40-65.
Main Methods:
- Screening of a random male population sample (aged 40-65).
- Ultrasonic Doppler velocimetry of major head arteries (MHA) in 866 subjects.
- Assessment of circulation normality, stenosis, and hemodynamic parameters.
Main Results:
- Only 13% of examinees exhibited normal MHA circulation.
- The majority (87%) presented with insufficient circulation or MHA stenosis.
- The average MHA stenosis index was 20.2%, correlating with age and vascular disease severity.
Conclusions:
- Widespread MHA atherosclerosis and stenosis are prevalent in men aged 40-65.
- Age and existing vascular disease significantly influence MHA stenosis frequency and severity.
- Ultrasonic Doppler velocimetry is effective for detecting MHA hemodynamic changes.
Abstract:
The screening of the random sample from an open population of males aged 40-65 was performed to compare frequency and severity of hemodynamic changes in major head arteries (MHA) due to atherosclerosis in subjects with vascular diseases and clinically normal controls. 866 of the examinees were subjected to MHA ultrasonic dopplerography. Normal circulation appeared only in 13% of the examinees. The rest of them had insufficient circulation or at least one vessel affected with stenosis. The standard index of MHA stenosis amounted to 20.2%. The frequency of MHA stenosis was related to the age, vascular involvement and severity of the latter.
