Awareness of risk factors for cerebrovascular diseases among acute ischemic stroke patients in Shenzhen, China.

Background and purpose: Unawareness of the risk factors is one of the most important issues that need to be settled for stroke prevention. We aimed to evaluate the awareness of risk factors for cerebrovascular diseases (CVDs) among acute ischemic stroke patients and to investigate the characteristics of patients who were unaware of their risk factors in Shenzhen, China.

Methods: Registered data on awareness of CVD risk factors of patients with confirmed acute ischemic stroke (AIS) from June 2020 to December 2022 were analyzed in May 2023. The data were extracted from the database of Shenzhen Quality Control Center for Management of Cerebrovascular Diseases.

Results: Totally, there were 5147 AIS patients with complete data eligible for this study. AIS patients' awareness regarding existing hypertension, diabetes, dyslipidemia, and atrial fibrillation (AF) was 76.1%, 76.2%, 24.2%, and 53.4%, respectively. Patients who were lack of awareness of the CVD risk factors were more likely to be males, individuals with younger ages, and those without medical insurance or a CVD history.

Conclusions: The overall awareness of the CVD risk factors was suboptimal among AIS patients in Shenzhen, especially for the existing dyslipidemia. The health education of AIS should be further improved in males as well as individuals without medical insurance or any CVD histories. Age was an independent factor associated with the lack of awareness of the CVD risk factors. The stroke screening program should be extended to younger people.
