The correlation of number of risk factors for stroke and occurrence of anterior versus posterior circulation infarction


Ali Abduljabbar Hameed, Riyadh Mustafa Al-shehristani

Background: Stroke which is a manifestation of cerebrovascular disease is noted as a leading cause of death worldwide. Identification of risk factors associated with stroke is an important contributing factor to consider. Few studies mentioned their association with the anterior circulation (AC) versus posterior circulation (PC) stroke as these have different pathogenesis. Aim: to evaluate the number of risk factors and their correlation with occurrence of AC versus PC brain infraction. Methods: In this observational cross-sectional study, we evaluated 71 (37 male, 34 female) consecutive patients presented with ischemic stroke. Among them 51 patients were diagnosed as AC infarction and 20 patients had PC infarction. We divided those patients into two age groups: below 65 and above 65 years old. Pre-stroke risk factors were recorded by the experts. Results: Regarding the age group distribution, patients having AC infarction below 65 years old were 21 (41.2%) and above 65 were 30 (58.8%), while those with PC infarction below 65 were 10 (50%) and above 65 were also 10 (50%), p 0.882. After estimating the impact of the number of risk factors for each patient in both groups, there was significant difference between association of multiple risk factors with PC infarction patients, 14 out of 20 (70%), versus AC infarction patients, 23 out of 51 (45%), p 0.034. Conclusion: PC infarction was significantly associated with multiple risk factors more than AC infarction. However, the impact of risk factors on AC and PC strokes and the prevalence were nearly equal in both sexes.
