Survival after cardiac transplantation: influence of the previous cardiopathy in the recipient

Transplant Proc. 2010 Oct;42(8):3173-4. doi: 10.1016/j.transproceed.2010.06.009.


Introduction: Data from cardiac transplantation registries have demonstrated a gradual improvement in patient survival over the last decades. Nevertheless, 5-years mortality rates may reflect the multitude of physiologic processes. Registries offer valuable information regarding predictors of mortality that may help us to improve therapeutic strategies.

Objectives: To determine the influence on long term recipient survival of the type of prior cardiopathy that led to cardiac transplantation.

Methods: Analysis of a 316 patient cohort who underwent heart transplantation since 1991 at a single center.

Results: We analyzed the main clinical variables among a cohort with a mean follow-up of 7.2 years (standard deviation [SD], 4.8). There were 84.2% men and the overall mean age of 50.06 years (SD 12.29) at the time of transplantation. We identified 11 cardiopathies as the leading causes for transplantation: severe ischemic cardiopathy (55.3%), dilated cardiomyopathy (29.1%), terminal valvular cardiopathy (5.4%), alcoholic cardiopathy (2.5%), congenital cardiopathy (1.6%), acute myocarditis (1.6%), hypertrophic cardiomyopathy (1.6%), endomyocardial fibrosis (1.3%), anthracyclin-related dilated cardiopathy (0.9%), peripartum cardiomyopathy (0.3%), and vascular allograft disease (0.3%). The mean global survival of the cohort was 4.1 years, which showed a significant increase in the recent 8 compared with the first 11 years (P=.03). Multivariate analysis only demonstrated worse survival rate among those with chronic ischemic compared with the other cardiopathies (HR 2.17; 1.21-6.2; P=.003). Nevertheless, the signification disappeared after adjusting the analysis for the presence of ≥2 classical cardiovascular risk factors.

Conclusion: Patients with chronic ischemic cardiopathy showed the leading cause for a lower survival after cardiac transplantation compared with other cardiopathies, which seemed to be related to the cardiovascular risk factors that produced the cardiopathy.
