Objective To investigate the condition of inflammation and prethrombotic state (PTS) of the aged patients with coronary heart disease(CHD) complicated with esstential hypertension(EH) and type 2 diabetes mellitns(T2DM). Methods The levds of fasting plasma hs-CRP,D-D and VWF were all measured in 86 CHD patients with EH,84 patients with T2DM,80 patients with EH and T2DM,91 CHD patients and 79 normal cases. Results Compared with normal group,diseases groups had significantly higher hs-CRP,D-D,and VWF,but compared with CHD with EH and T2DM group,other diseases groups had lower hs-CRP,D-D and VWF(P <0.05) ;The concentration of serum hs-CRP was positively correlated with D-D and VWF in CHD group (P < 0. 05). Conclusion The inflammation and hypercoagulable state is more significant in CHD patients with EH and T2DM,thns the levels of plasma hs-CRP,D-D and VWF play an important role in the treatment.
