The correlation between YKL-40,sCD40L,AFP and coronary heart disease / 国际检验医学杂志

ABSTRACT

Objective To study the chitin enzyme protein(YKL-40),sCD40L,AFP and the correlation of hypertension with cor-onary heart disease(CHD).Methods 75 cases of elderly patients with CHD were selected as observation group,and then were di-vided into hypertension group and non hypertension group according to the blood pressure.103 cases of healthy elderly were select-ed as control group.ELISA method was used to detect YKL-40 and sCD40L,and AFP was detected by chemiluminescence immuno-assay.Results Clinical data comparison revealed that the relative risk of CHD with hypertension group and non hypertension of hy-perlipidemia,drinking,smoking,diabetes mellitus,were 1.56,1.33,1.23,1.15 times,data show that relative risk of CHD with hy-pertension were much greater than CHD without hyperlipidemia.The concentration of YKL-40 in CHD with hypertension(92.66± 12.04)ng/mL was significant higher than that in CHD without hypertension (57.08 ± 10.07 )ng/mL,and the concentration of sCD40L in CHD with hypertension (186.59 ± 69.63 )ng/mL was significant higher than that in CHD without hypertension (128.14±48.37)ng/mL(P 0.05).Conclusion The levels of YKL-40,CD40L and AFP in the peripheral blood of elderly patients with CHD were significantly increased.And the concentration of sCD40L and YKL-40 was positively correlated with hy-pertension,which can be used to assess the stability and prognosis of CHD.
