Does the pretransplant UNOS status modify the short- and long-term cardiac transplant prognosis?
BACKGROUND
We compared the morbidity and mortality rates of patients who had urgent heart transplantation or transplantation after bridging with a ventricular assist device, with the rates of patients whose clinical stability allowed them to wait at home.


METHODS
From March 1985 to December 2000, 404 patients underwent heart transplantation in a single center. There were 273 patients with UNOS status 2 (US 2), 103 patients with UNOS Status 1A (US 1A), and 28 patients with UNOS Status 1B (US 1B). We compared the groups retrospectively with respect to pretransplantation status and operative results.


RESULTS
Despite more severely impaired hemodynamics and a significantly higher preoperative infection rate in US 1A and 1B patients, there were no statistically significant differences in survival rates among the three groups. Donor sex and age, cytomegalovirus and toxoplasmosis, mismatch rate, ischemic time, method of myocardial protection, and operative technique did not differ statistically among the three groups. Length of intensive care unit stay, postoperative morbidity, first year postoperative rejection rate, and graft occlusive vascular disease rate were statistically similar among the three groups. Although pretransplantation cancer assessment was less complete in US 1A and 1B than in US 2 patients, the late-cancer rate was not statistically different among the three groups.


CONCLUSIONS
These data suggest that urgently transplanted patients have both early and long term morbidity and mortality similar to those of patients waiting for transplantation at home or with a ventricular assist device.
