Complete Blood Count Parameters as Prognostic Factor of Stroke: A Systematic Review

Introduction: stroke is known as a common cause of disability all over the world. stroke prognosis estimation has always been a topic of interest. in this study, it was tried to investigate the prognostic value of laboratory findings of complete blood count in a systematic review. methods: in this systematic review, literature from medline via (pubmed, ovid) embase, scopus, cochrane library, and proquest between 1988 and 2020 were included. a combination of mesh and free terms were included in the search strategy: “stroke”, “red cell distribution width”, “blood cell count”, “mean corpuscular hemoglobin”, and “mean corpuscular volume” and with the abbreviation, in all fields. data synthesis was achieved using content analysis. results: elevated red blood cell distribution width was associated with stroke, cardiovascular events, and all-cause deaths among patients with prior stroke. mean platelet volume has not any prognostic significance in ischemic stroke. there was a poor association between mean corpuscular volume (mcv) and stroke prognosis. globulin and hemoglobin level predicted short-term mortality following acute ischemic stroke. conclusion: complete blood count as a routine and efficient test performed in health care centers can be used to estimate the prognosis of stroke.
