Abstract: (25 Views)
Introduction: Following the emergence of Coronavirus Disease 2019 (COVID-19), several vaccines were developed and authorized for emergency use worldwide. Given the widespread administration of these vaccines and concerns regarding potential neurological and thrombotic adverse events, it is important to evaluate their relationship with cerebrovascular diseases. This study aimed to investigate the clinical characteristics and mortality rate of vaccinated patients with ischemic stroke and compare them with unvaccinated patients.
Methods: This cross-sectional study was conducted on 257 patients with ischemic stroke admitted to Rajaei Hospital, Karaj, Iran, between July and October 2022. Data were collected using a structured checklist based on information obtained from medical records, patients, and their companions. Demographic and clinical characteristics, vaccination status, and outcomes were recorded and analyzed. The study was approved by the Ethics Committee of Alborz University of Medical Sciences (IR.ABZUMS.REC.1401.269).
Results: Univariate analysis demonstrated that age (P = 0.015), thrombocytopenia (P = 0.013), hyperlipidemia (P = 0.056), use of insulin (P = 0.044), atorvastatin (P = 0.015), clopidogrel (P = 0.030), and loss of consciousness (P = 0.037) were associated with COVID-19 vaccine acceptance. In multivariable logistic regression analysis, hyperlipidemia remained the only statistically significant factor associated with vaccine acceptance. Patients with hyperlipidemia were less likely to receive the COVID-19 vaccine than those without hyperlipidemia (P = 0.021, OR = 0.198). No other variables showed a significant independent association with vaccine acceptance.
Conclusion: Hyperlipidemia was significantly associated with COVID-19 vaccine acceptance among patients with ischemic stroke. Understanding factors associated with vaccination behavior in this high-risk population may facilitate the development of targeted educational programs and public health interventions aimed at improving vaccine uptake and reducing the risk of COVID-19-related complications.
