Coronary artery bypass grafting in patients with human immunodeficiency virus.

The role of surgery in the natural history of HIV disease is in evolution. A review was conducted of 2980 CABG operations taking place between January 1992 and January 1996 at St. Vincents Hospital; four of these patients were known to be HIV-positive prior to the operation. Preoperative work-up, operative course, and postoperative events were largely unremarkable. Only 1 of the 4 patients required rehospitalization within 30 days. Follow-up averaged 28 months (range 7-49 months). Three of four patients were in NYHA Class II or better at follow-up. Other reviews of CABG performed on HIV+ patients also indicate that, although CPB can be linked with immune suppression, there is no conclusive evidence of the acceleration of HIV into AIDS associated with CPB. In conclusion, due to the lack of controlled trials and large patient reviews, no firm recommendations about the effect of CPB on immunocompromized patients can be generated.
