简要总结
The investigators aimed to evaluate whether postoperative anemia can predict 1-year mortality after valvular heart surgery independent of preoperative anemia. Patients who underwent valvular heart surgery were divided into four groups according to whether or not they had preoperative and postoperative anemia. Postoperative one-year mortality, as well as overall mortality and a composite of death and heart failure requiring hospitalization, was investigated according to the groups, adjusted by confounders.

结局指标
主要结局
postoperative 1-year mortality
时间窗: One year after valvular heart surgery
The investigators assessed all-cause mortality during one year after valvular heart surgery and evaluated its association with preoperative and postoperative anemic status.
次要结局
- overall mortality(postopeartive one-year)
- composite of death and congestive heart failure (CHF) requiring rehospitalization(postopeartive one-year)
