Purpose. Intraoperative hypotension is associated with organ hypoperfusion, which is deleterious to vital organs. Little is known about the prevalence and consequences of intraoperative hypotension in subjects with arterial hypertension (AH). The primary goal of this study was to investigate the prevalence and determinants of hypoperfusion-related clinical consequences of intraoperative hypotension, taking into account the role of AH, in a homogeneous cohort of patients undergoing abdominal surgery. Materials and methods. We enrolled 508 patients (219 males, median age 62 years). Intraoperative hypotension was defined as systolic blood pressure (SBP) 30% than non-hypertensive patients (OR = 1.53; 95%CI 1.07–2.19; p = 0.02). The outcome was diagnosed in 38 (7.5%) patients. AH was a significant predictor of hypoperfusion-related events, regardless of the intraoperative hypotension definition applied (logOR 2.80 ÷ 3.22; p 10 min during surgery was identified as most associated with the negative outcome.
