Occurrence of intracranial large vessel occlusion in consecutive, non-referred patients with acute ischemic stroke

Table 1 Baseline characteristics of the study population with and without acute intracranial large vessel occlusion (LVO)

	LVO (n = 106)	No LVO (n = 232)	P-value
Age (years), mean (SD)	64 (15)	62 (16)	0.26
Male sex, n (%)	53 (50 %)	116 (50 %)	1.00
Caucasian ethnicity, n (%)	81 (76 %)	184 (79 %)	0.55
Systolic blood pressure, mean (SD)	161 (38)	167 (33)	0.16
Diastolic blood pressure, mean (SD)	85 (21)	89 (19)	0.11
BMI (kg/m²), mean (SD)	28 (3.8)	27 (5.1)	0.50
Glucose (mmol/L), mean (SD)	7.6 (2.4)	7.3 (2.8)	0.33
Previous ischemic stroke, n (%)	18 (17 %)	52 (23 %)	0.22
Previous heart disease, n (%)	14 (13 %)	41 (18 %)	0.28
Atrial fibrillation, n (%)	14 (13 %)	19 (8 %)	0.16
NIHSS on admission, median (IQR)	13 (6-18)	3 (2–7)	<0.01

All patients arrived at the emergency department within 6 h after onset of symptoms and received a CT-angiography of the intracranial circle of Willis in the acute phase. NIHSS on admission significantly differed between both groups
