Propensity matched cohort
In order to contextualise outcomes for patients experiencing a
postoperative stroke, propensity matching was utilised to identify a
matched cohort of patients. Comparison of demographic parameters is
presented in Table 3. On univariate analysis, there were some
differences between the two groups. Patients experiencing stroke tended
to have undergone more urgent or emergent procedures (p<0.01),
had a higher preoperative creatinine level (p=<0.01), were in
a higher NYHA class preoperatively (p=0.01) and were more likely to have
had a previous TIA (p=0.04).
