[Evaluation of some hemodynamic indices in 15 to 18 year old boys with lipid risk factors for atherosclerosis].

The aim of the work was an attempt at answering the question whether there is any correlation between the haemodynamic indices describing arterial elasticity assessed by physical analysis of the circulatory system and lipid risk factors for arterial atherosclerosis in boys aged 15 to 18 years. The studies included 45 boys with lipid risk factors for atherosclerosis. The control group included 53 boys without lipid risk factors. In boys aged 17-18 years with lipid risk factors for atherosclerosis as compared with their peers with normal serum lipid level, a statistically significant change of arterial elasticity was found. A positive correlation was also found between the increased serum cholesterol level and the values of air-chamber elasticity index and peripheral vascular resistance, and a negative correlation was demonstrated between the decreased serum HDL-cholesterol concentration and the increase of pulse wave velocity in the aorta, air-chamber elasticity index and peripheral vascular resistance.
