Cardiac dysfunction (n=35)
No cardiac dysfunction (n=37)
n = number; WFNS = World Federation of Neurological Surgeons.
* Hijdra score describes the amount of blood in the cisternal and ventricular spaces.10 ** Including vertebral, basilar, cerebellar and posterior cerebral arteries.
Mean CBF of the ROI with the lowest value was 15.83 mL/100g/min for patients with cardiac dysfunction and 18.59 mL/100g/min for patients without cardiac dysfunction (difference of means: -2.76; 95%CI:-5.43 to -0.09). Mean global CBF was 21.71 mL/100g/min for patients with cardiac dysfunction and 24.67 mL/100g/ min for patients without cardiac dysfunction (-2.96; 95%CI:-6.19 to 0.27). Mean TTP of the ROI with the highest value was 26.94 seconds for patients with and 23.10 seconds for patients without cardiac dysfunction (difference of means 3.84; 95%CI:1.63 to 6.05). Mean global TTP was 25.27 seconds for patients with cardiac dysfunction and 21.26 for patients without cardiac dysfunction (4.01; 95%CI:1.95 to 6.07) (Table 2).
