Prior studies report 9–27% of persons receiving a hematopoietic cell transplant develop arrhythmias, but the effect on outcomes is largely unknown. We reviewed data from 1177 consecutive patients {greater than or equal to}40 years old receiving a hematopoietic cell transplant at one center during 1999–2009. Transplant indication was predominately leukemia, lymphoma and multiple myeloma. Overall, 104 patients were found to have clinically significant arrhythmia: 43 prior to and 61 following transplant. Post-transplant arrhythmias were most frequently atrial fibrillation(N=30), atrial flutter(N=7) and supraventricular tachycardia(N=11). Subjects with an arrhythmia post-transplant were more likely to have longer median hospital stays (32 days vs 23, P=<.001,) a greater probability of an ICU admission (52% vs 7%; P<.001), more inhospital deaths (28% vs 3%, P<0.001), and more deaths within one year of transplant (41% vs 15%; P<0.001) than patients without arrhythmia at any time. In a multivariate model including age at transplant, diagnosis, history of pre-transplant arrhythmia, and transplant-related variables, post-transplant arrhythmia was associated with a greater risk of death within a year of transplant (OR 3.5, 95% CI: 2.1, 5.9; P < 0.001). Our data suggest arrhythmias after transplants are associated with significant morbidity and mortality. A prospective study of arrhythmia in the transplant setting is warranted.
The management of perioperative cardiovascular risk in patients with rheumatoid arthritis (RA) is challenging due to the independent contribution to risk by high grade inflammatory mechanisms and the underestimation of risk by traditional cardiac risk factors alone.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
