Insights
Heart transplantation is safe for patients over 60, showing comparable survival rates to younger recipients. Older individuals experienced fewer rejections but a higher risk of non-posttransplant lymphoproliferative disorder cancer.
Area of Science:
- Cardiology
- Transplantation Medicine
- Geriatric Medicine
Background:
- Traditionally, advanced age was a contraindication for heart transplantation.
- Increasingly, older individuals are considered for heart transplantation.
- This study evaluates long-term outcomes in heart transplant recipients over 60.
Purpose of the Study:
- To assess the long-term efficacy and safety of heart transplantation in patients aged 60 years and older.
- To compare outcomes between older (≥60 years) and younger (<60 years) heart transplant recipients.
Main Methods:
- A retrospective analysis of 81 heart transplant recipients aged 60-70 years compared with 403 younger recipients (1986-2001).
- Outcomes analyzed included 30-day mortality, actuarial survival, rejection episodes, allograft coronary artery disease, and post-transplant complications.
Main Results:
- Thirty-day mortality was similar (6%) in both older and younger groups.
- Actuarial survival at 1, 5, and 10 years was comparable between groups (e.g., 10-year survival: 50% +/- 9% vs. 51% +/- 3%).
- Older patients had significantly fewer rejection episodes but a higher incidence of non-posttransplant lymphoproliferative disorder cancer; other complications were similar.
Conclusions:
- Heart transplantation in selected patients aged 60 and older yields survival rates comparable to younger recipients.
- Advanced age is not an independent risk factor for mortality after heart transplantation.
- While older recipients have a lower risk of rejection, they face an increased risk of non-posttransplant lymphoproliferative disorder cancer.
Background:
Advanced age has been traditionally considered a relative contraindication for heart transplantation. Older patients are now considered as potential candidates for heart transplantation. The objective of this study was to evaluate the long-term results of heart transplantation in patients older than 60 years.
Methods:
Between 1986 and 2001, 81 patients aged between 60 and 70 years (mean, 63 +/- 2 years) underwent heart transplantation. These patients were compared with 403 adult recipients younger than 60 years (mean, 47 +/- 11 years) who underwent transplantation during the same period.
Results:
Thirty-day mortality was 6% (5/81) and 6% (25/403) in the older and younger patients, respectively (P = NS). Actuarial survival at 1, 5, and 10 years was 88% +/- 4% versus 83% +/- 2%, 75% +/- 5% versus 69% +/- 2%, and 50% +/- 9% versus 51% +/- 3% in the older and younger patients, respectively (P = NS). Older patients had significantly fewer rejection episodes (P =.003). Freedom from allograft coronary artery disease at 1, 5, and 10 years was 98% +/- 2% versus 92% +/- 2%, 85% +/- 6% versus 76% +/- 3%, and 81% +/- 7% versus 68% +/- 3% (P =.1). The incidences of infectious complication, cytomegalovirus infection, and posttransplant lymphoproliferative disorder were similar between the 2 groups, but older recipients were more likely to have a nonposttransplant lymphoproliferative disorder cancer (P =.002). Age at transplantation was not identified as an independent risk factor for early and late death.
Conclusion:
Heart transplantation in selected patients aged 60 years and older results in survival comparable with that of younger patients. Older patients have a lower risk of rejection but an increased risk of development of a nonposttransplant lymphoproliferative disorder cancer. Advanced age per se should not be considered as an exclusion criterion for transplantation.
