Objective To assess the influence of the risk factors of coronary heart disease(CHD) on the prognosis of pereutaneous coronary interventions (PCI). Methods The risk factors of CHD was retrospectively col-lected from 446 patients (mean age (SD) : 60.23(9.75) yrs,84.97% male )who were admitted to the First Affili-ated Hospital of Lanzhou University from January, 2007 to July, 2008. These patients were diagnosed as CHD and treated with PCI. Major adverse cardiac events (MACE) were followed up for 12 months after PCI,and its associatian with the risk factors of CHD was investigated. Results Among all the patients,2.24% (10/446) had family history of CHD, 20.63% (92/446) was complicated with diabetes, 52.26% (242/446) with hypertension, 42.15% (118/446) with dyslipidemia, 62.33% (278/446) of the patients was overweight, and 57.85% (258/446) was smoker. Within 12 months of follow-up, MACE incidence rate were 5.83%. Univariate analysis showed the propor-tions of female,family history of CHD, overweight, hypertension and smoker were significandy different between the patients with MACE and those without MACE (χ~2=4.133,6.848,3.997,3.939,4.120, respectively,P<0.05). Logistic regression analysis showed family history and overweight increased the risk of MACE (OR=7.383 and 10. 504,respectively,95% CI=1.639-33.246 and 1.231-59.598, P<0.05), being male protected against MACE (OR=0.058,95%CI=0.014-0.236,P<0.05). Conclusions The prognosis of patients of CHD under-went PCI was good. After PCI,the risk factors of CHD such as smoking,hypertension ,overweight,ete should be un-der control to decrease the occurrence of MACE.
