| Summary: | Background: To determine the frequency of
various subtypes of acute ischemic stroke among
patients using the TOAST criteria.
Methods: In this prospective, cross sectional study
156 consecutive stroke patients fulfilling the
inclusion criteria were recruited. Information on risk
factors like age, gender, diabetes and hypertension
was collected. Physical and neurological
examination was done and relevant investigations
were reviewed, to classify the subtype of stroke
according to TOAST criteria. . Risk factors like age,
gender, diabetes and hypertension were compared
with stroke subtypes after stratification using the
chi-square test with significance at p < 0.05.
Results: Out of the 156 patients with acute ischemic
stroke, mean age at presentation was 63.51 years.
Among them 75% had hypertension and 48.1% were
diabetics. The various subtypes of acute ischemic
stroke were Large artery atherosclerosis(35.3%)which
was the commonest cause. Large artery
atherosclerosis was found to be more common in
females (47.1% vs 25.6%) whereas cardioembolic
strokes were more common in males (29.1% vs
17.1%) (p value 0.02). When hypertension and
diabetes was compared with stroke subtypes the
results were statistically insignificant (p value.
>0.05).
Conclusion: Higher incidence of large artery and
cardioembolic disease was found. Preventive efforts
against the burden of ischemic stroke should focus
on risk factor intervention for each patient according
to subtype rather than ischemic stroke as a whole. |
