Second look Holter ECG in neurorehabilitation

Table 1 Patient characteristics including mean CHA₂DS₂VASc -score

Group	Ischemic stroke admitted to neuro-rehabilitation without diagnosis of AF	Ischemic stroke admitted to neuro-rehabilitation with diagnosis of AF	Hemorrhagic stroke	Group comparison
Number of patients	302	206	100
Mean age + SD	74 + 9	78 + 10	72 + 11	F = 15.36 p = .001 ^a
Prevalence of stroke risk factors on CHA₂DS₂VASc
Congestive heart failure	15%	22%	9%	X² = 8.61 p = .01 ^b
Hypertension	95%	98%	86%	X² = 17.52 P = .001 ^b
Age > 75 years	48%	72%	48%	X² = 31.41 P = .001 ^b
Age 65–74 years	37%	20%	31%	X² = 15.20 P = .001 ^b
Diabetes mellitus	21%	22%	17%	X² = 1.02 P = .60
Stroke/ TIA/ Thrombo-embolic events	100%	100%	3%	X² = 586.29 P = .001 ^b
Vascular disease	42%	17%	8%	X² = 60.78 P = .001 ^b
Female sex	47%	55%	51%	X² = 3.40 P = .18
Mean Total CHA₂DS₂VASc –score
Mean score + SD	5.52 ± 1.28	5.78 ± 1.18	3.03 ± 1.30	F = 182.57, P = .001 ^c

^a Pairwise post-hoc comparisons revealed hemorrhagic stroke patients were younger than both ischemic stroke patient groups (LSD, ps < .02), and ischemic stroke patients admitted with established AF were significantly older than ischemic stroke patients without AF documented during acute phase work-up (LSD, p = .001)
^b For Congestive heart failure, Hypertension and Stroke/TIA/Thrombo-embolic events the group effect was driven by a lower prevalence in the hemorrhagic stroke group compared to the two ischemic stroke groups. For Vascular disease sex the group effect was mainly driven by the ischemic group without established AF. For the two Age-related risk factors and Female sex the group effect was mainly driven by the ischemic group with established AF
^c Post-hoc comparisons showed that hemorrhagic stroke patients had a lower score than the two ischemic groups (LSD, ps < .03), and that ischemic stroke patients with no documentation of AF had a lower score than those with established AF (LSD, ps = .02)
