Evaluation of Cardiac Parameters in Bone Marrow Transplant Patients: Effect of Pulmonary Artery Pressure on Survival

Objective: Hematopoietic stem cell transplantation (HSCT) is a choice of treatment for malignant and non-malignant diseases. After HSCT, some complications may develop in patients. Cardiac complications are particularly important. The aim of this study was to investigate whether systolic pulmonary artery pressure (PAP) is a marker for overall survival (OS) in HSCT patients. Materials and Methods: In our study, 428 HSCT patients were evaluated. Ejection fraction (EF) and PAP values were investigated during symptom-oriented echocardiography in the pre-HSCT and post-HSCT periods. Results: Pre-HSCT EF values were similar between the groups. In patients with autologous HSCT (auto-HSCT) (PAP >25 mmHg), it was found that the 5-year mortality rate was 48.6%, while in the other group (PAP 25 mmHg, while OS was 61% in the pre-auto-HSCT period with PAP values of 0.05). Conclusion: Our results suggest that pre-HSCT PAP value is an important risk factor for mortality and OS in patients undergoing auto-HSCT.
