Abstract: |
Hematopoietic stem cell transplantation (HSCT) represents an extended period of physiologic stress. It is unknown whether patients with pre-existing coronary artery disease (CAD) may be poor transplant candidates. There are no data analyzing the risk of transplantation in this population. Sixty-nine patients with CAD who underwent 72 transplantations, autologous and allogeneic, were identified retrospectively. Fifty-five percent of these patients had prior percutaneous coronary intervention, 42% had verifiable history of myocardial infarction, and 23% had prior coronary artery bypass grafting. Outcomes were compared to 1109 patients without established CAD who underwent 1183 transplants during the same time period. Cancer diagnoses in the 2 groups were similar, predominantly lymphoma, multiple myeloma, and leukemia. There was no significant difference between the CAD group and the control group with respect to type of transplant (autologous 68% versus 64%, P = 612, myeloablative 86% versus 85%, P = 867). Treatment-related mortality was no different in the CAD group versus the control group (5.6% versus 4.9%, P = 777), nor were there differences in mortality at 1 year (15.3% versus 16.6%, P = 871), urgent intensive care unit admission (11.1% versus 9.9%, P = 686), or length of stay (25.5 days versus 28.4 days, P = 195). These findings suggest many patients with underlying coronary artery disease may be safely managed through hematopoietic stem cell transplantation. © 2011 American Society for Blood and Marrow Transplantation. |
