AbstractRisk factors for peri-operative cardiac morbidity are poorly described in HIV-positive patients. This prospective observational study describes cardiovascular risk factors in a cohort of vascular surgical patients of known HIV status. We recruited 225 patients with 73 (32%) being HIV-positive. When compared with HIV-negative patients, the HIV-positive patients were younger (mean (SD) 56.4 (13.3) vs 40.5 (10.4) years, respectively, p < 0.01). They had fewer Revised Cardiac Risk Index cardiovascular risk factors (median (range [IQR]) 1 (0-5 [0-2]) vs 0 (0-2 [0-0]), respectively, p < 0.001), with the exception of congestive cardiac failure (p = 0.23) and renal dysfunction (p = 0.32), and so were of a significantly lower Revised Cardiac Risk Index risk category (p < 0.01). HIV-positive and -negative patients had similar outcomes in: 30-day mortality (p = 0.78); three-day postoperative troponin leak (p = 0.66); and a composite outcome of mortality and troponin release (p = 0.69). We conclude that although HIV-positive patients have fewer cardiovascular risk factors, they have similar peri-operative major adverse cardiac events to HIV-negative patients. Research should focus on why this is the case, and if alternative clinical risk predictors can be developed for HIV patients.© 2013 The Association of Anaesthetists of Great Britain and Ireland.
