Abstract:
The levels of serum lipids, lipoproteins and apoproteins were determined in 36 age over 90 year long-living people, 43 patients with old myocardial infarction (OMI) and 56 normal subjects of the age 40 to 64 years old. The resutts showed that: the ratioes of HDL-c/TC, HDL-c/LDL-c and ApoA_1/ApoB_(100) of the long-living people were higher than that of the patients with OMI; the levels of TC, TG, LDL-c, VLDL-c, ApoB_(100) and ApoA_1 in longevity group were lower than that of OMI group; no significant difference of HDL-c level was found between longevity and OMI group. Compared with normal group, the serum concentration of ApoA_1/ApoB_(100) ratio, TG and VLDL-c in the long-living group were obviously higher, and the serum concentration of ApoB_(100), ApoA_1 and HDL-c significantly lower. No significant differences were found in the levels of TC, LDL-c, and in the ratioes of HDL-c/TC and HDL-c/LDL-c between longevity and normal group. Stepwise regression analysis showed that the serum ApoB_(100) concentration and ApoA_1/ApoB_(100) ratio was the most important factor of longevity. It was suggested that the internal balance of serum lipids and lipoprotein metabolism in long-living people was good co-ordination, and the lower ApoB_(100) level and higher ApoA_1/ApoB_(100) ratio were probably parameters of longevity.
