Correlation between neurological status and
cardiac function in aneurysmal SAH group:
a- Correlation between neurological status and
ECG analysis:
In the present study, we evaluated the neurological
status of the studied patients by Hess &
Hunt scoring system and divided them into:
Twelve patients exhibited mild affection (Hess
& Hunt score 1&2) while severe affection (Hess
& Hunt score 3-5) was exhibited by 8 patients.
There was a statistically significant higher
frequency of abnormal ECG on day 1 in those
patients with severe aneurysmal SAH (H&H score
3-5) when compared to those with mild aneurysmal
SAH (H&H score 1&2) (100% vs 58.3%) (p value=0.035),
Fig. (1). On day 7 there was no statistically
significant difference between both groups
(75% versus 41.7%, p value=0.142).

b- Correlation between neurological status and
cardiac troponin I measurement:
Out of twelve patients included in the mild
aneurysmal SAH group, none showed positive
cardiac troponin I on day 1 (0%), while six (out
of eight patients) included in the severe aneurysmal
SAH group (75%) had positive cardiac troponin I
(p value=0.001) Fig. (2).

Similarly, we found a statistically significant
higher frequency of positive cardiac troponin I in
day 7 in those patients with severe aneurysmal
SAH (37.5%) when compared to cases with mild
aneurysmal SAH (0%) (p value=0.021) Fig. (3).

c- Correlation between neurological status and
echocardigraphic findings:
In the present work there was a statistically
significant higher incidence of systolic dysfunction
(global & regional) in the cases with severe aneurysmal
SAH (37.5%) when compared to cases with
mild aneurysmal SAH (0%) (p value=0.021) in
day 1, with no statistically significant difference
between both subgroups in day 7 (p value=0.4)
