Purpose: In kidney and liver transplantation, chronic narcotic use pre and post-transplant has been associated with an increased risk for rejection and early graft loss. There is a paucity of information on the adverse clinical outcomes associated with chronic narcotic use in heart transplant (HT) recipients.
Methods: We conducted a retrospective chart review of adults who underwent HT at our institution from January 1, 2007 to June 30, 2016 using electronic medical records. Patients were stratified into groups by narcotic use. Chronic narcotic use (CNU) was defined as positive or negative at 6 months prior to transplant (pre transplant) and 6 months post-transplant. Univariate two-group comparisons were carried out using independent two-group t-tests for continuous variables, and chi-square tests for categorical variables. Survival distributions were compared between groups using log-rank tests.
Results: 115 underwent HT, 81% were male, mean age 53.8 ±11 years, 48% white and 43% black. CNU pre transplant (N=26) had more illicit drug use (58% vs 28% p=.005), psychiatric history (77% vs 49% p=.013) and criminal history (38% vs 16% P=.012) than those without narcotic use pre-transplant. CNU post-transplant (N=32) had more illicit drug use (50% vs 29% p=.033), psychiatric history (75% vs 48% p=.010) and criminal history (38% vs 14% P=.006) than those without narcotic use post-transplant. No differences were observed in the rate of rejection amongst the groups. Table 1 contains the median survival time in months along with 1-, 3-, and 5-year survival probabilities with their standard errors (SE) of both groups. The 1-, 3- and 5-year survival is worse in patients with CNU post-transplant.

Median survival time in months (95% CI)
1-year survival probability (SE)
3-year survival probability (SE)
5-year survival probability (SE)
No narcotics pre transplant
119.6 (109.6, N/A)
Narcotics pre transplant
N/A (20.5, N/A)
No narcotics post-transplant
119.6 (109.6, N/A)
N/A (19.2, N/A)
Conclusion. Patients without CNU post-transplant have higher survival probabilities at each of the three time points than those with CNU post-transplant. Additional studies are warranted to confirm observed associations.
