NOT REALLY!!!!
This study showed THREE times risk of stroke when the patient is dependent preoperatively! If you see such a patient, never quote your outcome for stroke; but rather quote three times your figures .. and be careful: how much benefits you expect to achieve if you operate on this patient: balancer it carefully to be on the safe and correct side.
Here are their findings:
Of 19 748 CEAs, 19 348 (97.97%) were functionally independent, 377 (1.99%) were functionally partially dependent, and 23 (0.12%) were functionallydependent.
In functionally independent group, there were 196 (1.01%) strokes, 84 (0.43%) deaths, and 1416 (7.17%) other complications,
whereas in the functionally partially dependent group, there were 14 (3.71%) strokes, 10 (2.65%) deaths, and 80 (21.22%) other complications.
In multivariable risk-adjusted model, using functionally independent as reference, functionally partially dependent was associated with death (odds ratio, 3.3; 95% confidence interval, 1.6–6.8; P<0.001), stroke (odds ratio, 3; 95% confidence interval, 1.7–5.4;P<0.001), and other complications (odds ratio, 2.5; 95% confidence interval, 1.9–3.2; P<0.001).
