Abstract
Highlights
The authors have studied anemia`s impact on the long-term mortality after mitral valve surgery. The research results indicate the need to address this modifiable factor in the preoperative period.
Aim. To analyze the impact of anemia on the long-term survival of patients after mitral valve surgery.
Methods. The study included 103 patients, 46 of them were men, 57 were women. Thirteen patients presented with anemia before surgery, and 90 patients did not have anemia. The survival rate of patients was compared using the Kaplan-Meier estimate.
Results. The survival rate after surgery in the group of patients without anemia was higher compared with patients with anemia (p = 0,002). By the end of the follow-up period, the survival rate among patients without anemia reached 50.2%, whereas among patients with anemia it was 0.0%.
Conclusion. Anemia is an independent predictor of complications in the postoperative period in patients with low preoperative hemoglobin levels. According to the results, the presence of anemia increases the risk of adverse events by 7.71 times in the preoperative period. Moreover, patients without anemia had the highest (up to 50.2%) survival rate in the long-term period, while patients with anemia had a survival rate equal to 0.0%.
