Abstract
Although racial disparities in cardiac interventions have been studied extensively, disparities in heart transplants (HTs) and left ventricular assist devices (LVADs) have not been well-established. A systematic review was undertaken wherein 20 studies were identified for investigation, with a total of 785,486 patients. Of these, 104,356 patients were studied to assess HT and LVAD access, 332,885 patients were studied to assess in-hospital mortality rate, 346,303 patients were studied to assess organ function, and 1,942 patients were studied to assess costs associated with HT or LVAD treatment among different racial groups. Access was evaluated via the percentage of patient race within each study's population. White patients received the majority of LVADs (44,248 patients, 63.34%) and HTs (21,273 patients, 61.67%), followed by Black patients for LVADs (16,437 patients, 23.53%) and HTs (7,603 patients, 22.04%). Hispanic/Latino patients had the lowest rates of LVADs (4,071 patients, 5.83%) and HTs (3,153 patients, 9.14%). Asian patients had the highest in-hospital mortality (4,104 patients, 39.2%), whereas White patients had the lowest (84,977 patients, 36.2%). Results of cost outcomes varied, with Asian patients having the highest mean cost and Black patients having the lowest mean cost for transplantation. Racial disparities in HTs and LVADs were noted, highlighting the need for multi-faceted approaches to provide equitable access and improved outcomes.
