ABSTRACT
Objective:To compare the long-term prognosis of percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) in patients with ostial/shaft lesions of unprotected left main coronary artery (ULMCA).Methods:A total of 259 patients with isolated ostial/midshaft lesions of ULMCA who received PCI or CABG in our hospital from 2003-01 to 2009-07 were enrolled.The patients were divided into 2 groups:PCI group,n=149 patients who received drug-eluting stents (DES) implantation and CABG group,n=110.The end points were all cause death,myocardial infarction (MI) and major adverse cardiac and cerebrovascular events (MACCE) which included cardiac death,non-fetal MI,stroke,repeated revascularization and the composite events death.Results:The median follow-up period was 7.1 years (inter quartile range 5.3-8.2 years) in all patients.Before multivariate adjusting,the following parameters were similar between PCI group and CABG group:all cause death (12.7％ vs 29.7％),P=-0.096;non-fatal MI (14.8％ vs 8.5％),P=0.844;stroke (9.3％ vs 6.3％),P=0.904;repeated revascularization (26.8％ vs 19.0％),P=0.234;composite events of cardiac death/stroke/MI (18.9％ vs 20.3％),P=0.224 and MACCE occurrence (37.5％ vs 34.2％),P=0.946.With adjusted variations,the trend was similar to pre-adjustment.Conclusion:During the maximum 8.2 years follow-up period,PCI and CABG had the similar efficacy and safety in patients with ostial/shaft lesions of ULMCA.

ABSTRACT
Objective: To explore the relationship between ABO blood group and acute non-ST-segment elevation myocardial infarction (NSTEMI) occurrence. Methods: Our research included 2 groups: NSTEMI group, 1039 relevant patients treated in Anzhen hospital from 2013-01 to 2014-12 were retrospectively enrolled; Control group, 1039 subjects with normal coronary artery which was confirmed by coronary angiography. The Baseline condition including age, previous disease history and ABO blood group was studied. Logistic regression model was used to conduct single and multivariate analysis. Results: In NSTEMI group and Control group, blood type A was 287/1039 (27.6％) vs 259 (24.9％), type B was 345 (33.3％) vs 356 (34.3％), type AB was 102 (9.8％) vs 114 (11.0％) and type O was 305 (29.4％) vs 310 (29.8％), ABO blood group distribution for A and non-A, B and non-B, AB and non-AB blood group, O and non-O had no statistic meaning between 2 groups, P>0.05. Logistic regression analysis indicated that with adjusted risk factors of MI such as age, gender, hypertension, diabetes, hyperlipemia, cerebrovascular disease and smoking, the patients with blood types A, B and AB had the similar risk for NSTEMI occurrence than type O patients; there was no relationship between ABO blood group and NSTEMI occurrence. Conclusion: ABO blood group had no relationship to NSTEMI occurrence.
