Objective To investigate the value of CRUSADE scoring system in the baseline assessment of upper gastrointestinal hemorrhage after percutaneous coronary intervention(PCI).Methods 476 patients with upper gastrointestinal hemorrhage following PCI in our hospital from May 2008 to October 2009 were included in this study.According to the evaluation results of CRUSADE scoring system on admission,they were divided into very low-risk group(105 cases),low-risk group(190 cases),moderate-risk group(92 cases),high-risk group(70 cases)and very high-risk group(19 cases).The relationship between CRUSADE scores and obvious upper gastrointestinal hemorrhage within a year after PCI was analyzed.Results Obvious upper gastrointestinal bleeding occurred in 7 cases within 1 year after PCI,including 2 cases(1.05%)in low-risk group,1 case(1.09%)in moderate-risk group,1 case(1.43%)in high-risk group,3 cases(15.8%)in very high-risk group,and no case in very low-risk group.The total hemorrhage rate was 1.47%.It demonstrated that the incidence of gastrointestinal bleeding increased with the increase of CRUSADE score,and the hemorrhage rate in very high-risk group was significantly higher than that in other groups(P<0.05).Conclusion CRUSADE scoring system is of good value in the baseline assessment of the incidence of upper gastrointestinal bleeding after PCI.

Objective To study the clinical manifestations and coronary artery disease features in coronary heart disease(CHD) patients with type 2 diabetes mellitus(DM).Methods 148 patients with coronary heart disease diagnosed by coronary angiography were involved in the present study,in which 70 patients with DM as the observation group and 78 patients without DM as the control group.The clinical characters and coronary angiographic features were analyzed.Results Age,sex,hypertension,hyperlipidemia and smoking history had no significant difference between two groups(P0.05).The TG,LDL-L levels in the observation group were significantly higher than the control group,and the HDL-L level is significantly lower(P0.05),the coronary artery lesions of observation group is dominated by multi-vessel disease and diffuse lesions,the stenosis is severe(P0.05).Conclusion Dyslipidemia is more pronounced in patients with coronary heart disease and type 2 diabetes mellitus,the characteristics of coronary artery lesions is multi-vessel,widespread and diffused.
