ABSTRACTS SA HEART CONGRESS 2009 Risk factors associated with six-month mortality following vascular surgery Jamila Khatoon Adam, Bruce Biccard, Sumansha Nepaul and Wafaa N.S. Rmaih Durban University of Technology, Department of Biomedical and Clinical Technology, Durban, KwaZulu-Natal, South Africa Introduction: Every day a large number of patients undergo vascular surgery, but not all of these patients survive surgery. By looking at risk factors identifi ed in previous studies the outcome of some patients’ surgery may be predicted. However, there is a limited number of studies on South African patients with regards to risk factors associated with post-operative vascular surgical survival. The aim of this study was to identify risk factors associated with six-month mortality following vascular surgery. Methods: Patients selected (>39y) for this study were scheduled for both elective and emergency vascular surgery at Inkosi Albert Luthuli Central Hospital, between June 2003 and July 2007. Demographic data from the hospital computerised data base was extracted, as well as patients’ date of surgery and their inpatient and outpatient visit dates. The patients’ hospital visits following surgery were analysed. 283 patients were included. The risk factors examined in this study were; male sex, history of smoking, ischaemic heart disease, congestive cardiac failure; cerebrovascular accident, diabetes, hypertension, creatinine >180 μmol.L-1, chronic beta-blockade, major vascular surgery, mean daily heart rate (HR) the day before surgery; mean daily HR on the third postoperative day and mean daily systolic blood pressure (SBP) < 100 or > 179mmHg. These factors were entered into a bivariate cox regression analysis. Risk factors with a p < 0.1 were entered into a multivariate analysis.
