[High-density lipoprotein cholesterol and the atherogenic index in patients with different types of hyperlipoproteinemias].

A total of 180 subjects (82 males and 98 females), aged from 20 to 60 were examined. Sixty four of them (29 males and 35 females) were regular blood donors (control group) and 116 subjects (53 males and 63 females) - with huperlipoproteinemias: type IIa - 50 subjects (17 males and 33 females), type IIb - 37 (23 males and 14 females) and type IV - 29 (13 males and 16 females). Triglycerides, total cholesterol and cholesterol in lipoproteins with high density (Ch-HDLP) were also determined. The percentage of Ch-HDLP was calculated from total cholesterol (TCh) as well as the atherogenic index [(TCh-Ch-HDLP): Ch-KDLP)] A drop down of Ch-HDLP (p less than 0,01) was found only in hyperlipoproteinemia type IV, as compared with the control group. Ch-HDLP percentage was diminished (p less than 0,001) whereas the atherogenic index was increased (p less than 0,001) in hyperlipoproteinemias from the three types. Both sexes were affected by the changes decrided.
