Human immunodeficiency virus infection is associated with greater risk of pneumonia and readmission after cardiac surgery.

Human immunodeficiency virus infection (HIV+) is associated with a 2-fold increased risk of cardiovascular disease. Increasingly, patients who are HIV + are being evaluated to undergo cardiac surgery. Current risk-adjusted scoring systems, including the Society of Thoracic Surgeons Predicted Risk of Mortality score, fail to stratify HIV + risk. Unfortunately, there exists a paucity of cardiac surgery outcomes data in modern patients who are HIV+. We conducted a retrospective review of PearlDiver, an all-payer claims administrative database. In total, 14,714,743 patients were captured between 2010 and 2020. Of these, 59,695 (0.4%) of patients had a history of HIV+, and 1759 (2.95%) of these patients underwent cardiac surgery. Patients who were HIV+ were younger, more often male, and had greater comorbidity, history of hypertension, chronic obstructive pulmonary disease, chronic liver disease, chronic kidney disease, chronic lung disease, and heart failure. Postoperatively, patients who were HIV + had significantly greater rates of pneumonia (relative risk, 1.70; Patients who are HIV + undergoing cardiac surgery are at greater risk of pneumonia and readmission. Moreover, we discovered lower rates of cardiac surgery in patients who are HIV+, which may reflect limited access to surgery when indicated. Today's risk-adjusted scoring systems in cardiac surgery need to better account for the modern patient who is HIV+.
