Abstract:
Objective: To evaluate the impact of anemia on prognosis of elder patients with acute coronary syndrome (ACS) after percutaneous coronary intervention (PCI).
Methods: A total of 908 consecutive ACS patients elder than 60 years of age with PCI in our hospital from 2010-06 to 2012-06 were studied. According to WHO deifnition of anemia (HB<12.0 g/dL in female and HB<13.0 g/dL in male), the patients were classiifed as Anemia group, n=283 and Non-anemia group, n=625. The patients were followed-up for 1 year. The basic clinical characteristics, incidences of mortality and major adverse cardiovascular and cerebravascular events (MACCE) were compared between 2 groups by cardiac death, myocardial re-infarction, worsening of cardiac function, target vessel revascularization, cerebral hemorrhage and cerebral infarction.
Results: There were 31%of patients suffering from anemia. Anemia group had more patients with the elder age, female gender, diabetes, hypertension, chronic kidney disease, decreased LVEF, more patients with 3 vessel-disease, and higher mortality at 1 year after PCI, higher rate of MACCE than those in Non-anemia group, all P<0.05. Multiple regression analysis indicated that anemia is the independent predictor for mortality in elder ACS patients at 1 year after PCI, P<0.05.
Conclusion: Anemia may increase the incidences of mortality and MACCE in elder ACS patients after PCI for a long-term.
