Allogeneic hematopoietic stem-cell transplantation was associated with a significantly higher risk of arterial events compared to autologous transplantation (RR 14.5; P=0.003).
Cohort (n=410)
Does allogeneic HSCT increase the risk of arterial events compared to autologous HSCT in long-term survivors?
Long-term survivors of allogeneic HSCT are at a significantly higher risk for premature arterial vascular disease compared to those receiving autologous HSCT.
Relative Risk: 14.5
Absolute Event Rate: 6.8% vs 2.1%
p-value: p=0.003
We assessed incidence and risk factors of cardiovascular events in 265 patients undergoing allogeneic hematopoietic stem-cell transplantation (HSCT) between 1980 and 2000 and who survived at least 2 years. Results were compared with a cohort of 145 patients treated during the same period with autologous HSCT. The median age of patients with allogeneic HSCT at last follow-up was 39 years, and median follow-up was 9 years. Eighteen (6.8%) patients after allogeneic and 3 (2.1%) patients after autologous HSCT experienced an arterial event. The cumulative incidence of first arterial event after allogeneic HSCT was 22.1% (95% CI, 12.0-40.9) at 25 years. The cumulative incidence 15 years after allogeneic HSCT was 7.5% as compared with 2.3% after autologous HSCT. Adjusting for age, risk of an arterial event was significantly higher after allogeneic HSCT (RR 6.92; P =.009). In multivariate analysis, allogeneic HSCT (RR: 14.5; P =.003), and at least 2 of 4 cardiovascular risk factors (hypertension, dyslipidemia, diabetes, obesity) (RR: 12.4; P =.02) were associated with a higher incidence of arterial events after HSCT. Thus, long-term survivors after allogeneic HSCT are at high risk for premature arterial vascular disease. HSCT might favor the emergence of established risk factors, such as hypertension, diabetes, and dyslipidemia.
Tichelli et al. (Mon,) conducted a cohort in Hematopoietic stem-cell transplantation (n=410). Allogeneic hematopoietic stem-cell transplantation vs. Autologous hematopoietic stem-cell transplantation was evaluated on Arterial event (RR 14.5, p=0.003). Allogeneic hematopoietic stem-cell transplantation was associated with a significantly higher risk of arterial events compared to autologous transplantation (RR 14.5; P=0.003).
