In previous studies, 90% of patients who underwent elective cardiopulmonary bypass procedure manifested CD4 counts of less than 500 cells/microliter in the immediate (day 1) post-operative period. This study will investigate whether or not Nelfinavir increases those CD4 counts in the post-operative period.
