title: [Impact of chronic anemia on in-hospital clinical outcome of revascularization in patients with coronary artery disease].
abstract: OBJECTIVE
  To evaluate the in-hospital clinical outcome of revascularization in patients with coronary artery disease with chronic anemia.
  
  
  METHODS
  Between July 2002 and June 2004, 3 679 patients in Anzhen Hospital Affiliated to Capital University of Medical Sciences were subjected to revascularization [percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG)] during hospitalization. These patients were divided into anemia group and non-anemia group according to blood hemoglobin (Hb) level [World Health Organization (WHO) standard (male<120 g/L, female<110 g/L) as anemia]. Rates of in-hospital main adverse cardiac and cerebral events (MACCE), including all-cause death, new attack of myocardial infarction, stroke and repeated revascularization were compared between two groups.
  
  
  RESULTS
  There were 426 anemia patients (11.6%) and 3 253 non-anemia patients (88.4%). In-hospital death in the anemia group was higher than that of the non-anemia group [10 cases (2.4%) vs. 64 cases (1.9%), P<0.05]. Rates of MACCE of the anemia group was higher than that of the non-anemia group (4.2% vs. 3.2%, P<0.05). There was no significant difference in rates of new attack of myocardial infarction (0.7% vs. 0.6%), stroke (1.2% vs. 0.4%) and repeated revascularization (0 vs. 0.2%) between two groups (all P>0.05).
  
  
  CONCLUSIONS
  Compared with non-anemia patients, anemia patients with coronary artery disease has higher in-hospital MACCE rate and all-cause mortality.
