Determination of Ischemic Stroke Clinical Outcomes in the Anterior and Posterior Circulatory Territory and Its Relationship with the First Stroke Attack

Abstract

Considering the importance and prevalence of ischemic stroke and the impact it has on human life and society as well as the health care system, and due to the lack of a comprehensive study on the differences between ischemic stroke, anterior and posterior circulation, using the findings The results of this study can play an important role in timely diagnosis and assignment of patients and prevent harm to the patient and society. Aim: To determine the clinical consequences of ischemic stroke in the range of anterior and posterior circulation in patients with first stroke Matherials and Methods: The selection of patients in the study was a total of one year. All patients with the first ischemic stroke experience entered the study. The number of patients was 701. The required information was collected and recorded from the Stroke regisrtey system. Patients were divided into 5 groups based on the National Institutes of Health (NIHSS) Strategy Scale. Patients with no evidence of stroke (score 0), patients with minor stroke (score 1-4), moderate stroke (5-15), moderate to severe stroke (16-20) and severe stroke (42-21). The results were analyzed in SPSS V24 software. Results: In the study period, 701 eligible patients were included in the study, of which 524 (74.75%) were patients with ACI stroke and 177 (25.24%) were PCI stroke type. Regarding the age of patients, the mean age of the ACI group was 68.39 and the PCI group was 67.97, which were not statistically different from each other. Regarding the sexual distribution of patients in the ACI group, 302 were male and 222 were female. In PCI group, 106 men were 71 women and statistical analysis did not show a significant difference in terms of sex distribution (p = 0.559). Our study also showed that in patients presenting with acute ischemia, the higher the MRS score at the first visit, the higher the mortality and disability. Our other finding was that patients with PCI involvement had a higher rate of disability, but because the number of PCI patients in the community was lower, they were usually not as pronounced as those with ACI involvement. On the other hand, it was predicted that patients with large arterial stroke (LAA) were associated with higher mortality and disability rates, which is more evident in patients with PCI involvement.
