FREQUENCY OF ABO BLOOD GROUPS AMONG PATIENTS WITH ISCHEMIC STROKE

Abstract

Objective: The objective of this study was to find out the blood groups among the patients presenting with ischemic stroke either AB blood group or O blood group is more common (frequent) among these patients irrespective of other known factors responsible for stroke.

Materials &Methods:

We included total 292 patients (40-70 years of age), with ischemic stroke documented on CT scan brain of both gender (male and female).Blood sample of these patients were sent to the central laboratory of hospital for blood group determination using standard techniques.

Results:

Mean age was 56.26 ± 8.28 years. Out of the 292 patients, 163 (55.82%) were male and 129 (44.18%) were females with male to female ratio of 1.3:1. Frequency of blood group A, B, AB and O was found to be 114patients blood group A (39.04%), 53patients blood group B (18.15%), 26patients blood group AB (8.90%) and 99patients blood group O (33.90%) respectively.

Conclusion:

Our study results concluded that there is an association between ABO blood groups and ischemic stroke, irrespective of other risk factors. Our study results have observed that individuals belonging to non-O blood groups (A, B, or AB) are at an increased risk of ischemic stroke as compared to O blood group carriers however we did not control possible impact of confounders such as diabetes, hypertension and dyslipidemia etc .Many studies proved that persons with AB blood groups are at increased of atherosclerosis but no study showed that these persons have increased risk of ischemic stroke or not.
