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.

postoperative 1-year mortality
The investigators assessed all-cause mortality during one year after valvular heart surgery and evaluated its association with preoperative and postoperative anemic status.
Time frame: One year after valvular heart surgery
overall mortality
The investigators assessed overall mortality during the follow-up period and a composite of death and congestive heart failure (CHF) requiring rehospitalization during the postoperative one-year and evaluated their associations with preoperative and postoperative anemic status.
Time frame: postopeartive one-year
composite of death and congestive heart failure (CHF) requiring rehospitalization
The investigators assessed overall mortality during the follow-up period and a composite of death and congestive heart failure (CHF) requiring rehospitalization during the postoperative one-year and evaluated their associations with preoperative and postoperative anemic status.
Time frame: postopeartive one-year
