A study of platelet volume indices in a patients of ischaemic cerebrovascular disease.

ABSTRACT

Background: The objective of the study is to estimate platelet volume indices in patients of cerebral ischemic vascular disease. Methods: The present study was conducted on 170 subjects in Department of Medicine, NIMS Medical College and Hospital, Jaipur, Rajasthan over eighteen months. The study was conducted on 60 patients admitted in the wards and ICU under the Department of Medicine and 110 controls who were the normal and healthy during the study period. In this study the values of platelet indices – MPV, PDW and platelet count were observed in patients of cerebral ischemia. It was found that large platelets contribute to the prethrombotic state in ischemic syndromes and they may play a specific role in infarction. Because larger platelets are haemostatically more active and hence, their presence is probably a risk factor for developing thrombosis. Statistical analysis was done using Chi – square test, unpaired ‘t’ test and ANOVA test. A p value <0.05 was considered statistically significant. Results: In this study it was found that in cerebrovascular disease patients, MPV was 10.30±0.83 fL, PDW was 14.50±0.55 fL, platelet count was 260×109 ± 29×109 /L while in control, MPV was 8.14± 0.72 fL, PDW was 10.71±0.48 fL, platelet count was 285×109 ± 50 ×109 /L. MPV and PDW were higher and platelet count lower in cerebrovascular disease group and a highly significant difference (p<0.001) was found on comparing with controls. Conclusion: In this study, it was found that MPV and PDW were raised in cerebrovascular disease suggestive of statistically highly significant when compared to normal control group.
