| Popis: | Background The utility of long-term endomyocardial biopsy surveillance in heart transplant recipients has been questioned. This study was undertaken to identify risk factors for late rejection and to examine the impact of different biopsy surveillance protocols on outcomes using the registry of the Cardiac Transplant Research Database. Methods The study group consisted of all adult patients who underwent heart transplantation at the 33 centers participating in this investigation between January 1, 1993 and January 1, 2002, survived past the second post-transplant year, and were followed-up by a defined surveillance biopsy protocol. Results During a follow-up that consisted of 24,137 patient-years, 1,626 late rejections occurred. Shorter time since transplant, history of rejection, younger age and African-American ethnicity of the recipient were strong risk factors for late rejection. The practice of surveillance biopsy varied among institutions. Continued surveillance increased the rate of diagnosis of late rejection (RR = 1.3, p = 0.002). There was no reduction in the incidence of hemodynamically compromising rejection and no increase in survival in patients with long-term vs intermediate-term surveillance. Short-term surveillance was associated with an increased incidence of hemodynamically compromising rejection, particularly among high-risk patients, and increased mortality in African-American patients. Conclusions There are no apparent benefits from surveillance biopsy beyond 5 years post-transplant. Surveillance biopsy between 2 and 5 years post-transplant was found to reduce mortality in African-American recipients. Non–African-American recipients at high risk for late rejection will likely benefit from surveillance up to 5 years post-transplant. |
