Improved management of stroke risk factors like hypertension and atrial fibrillation is crucial for preventing ischemic events. This study shows a positive trend in risk factor control, though some events remain preventable.

Area of Science:

  • Neurology
  • Cardiology
  • Public Health

Background:

  • Identification and control of risk factors are proven to reduce ischemic stroke incidence.
  • The real-world impact of evidence-based stroke prevention strategies on clinical practice is not well understood.

Purpose of the Study:

  • To examine the management of pre-existing risk factors in patients diagnosed with acute cerebral infarction.
  • To assess the appropriateness of prior risk factor management against established criteria.

Main Methods:

  • Observational study analyzing data from 1,074 patients over three years.
  • Collected data on the prevalence of hypertension, atrial fibrillation, prior stroke/TIA, and diabetes before the index stroke.
  • Compared the proportion of patients receiving treatment for these risk factors over time.

Main Results:

  • While the prevalence of hypertension, diabetes, and prior stroke/TIA remained stable, treatment rates for cerebrovascular disease, atrial fibrillation, ischemic heart disease, and carotid disease significantly increased over three years.
  • Approximately 45% of atrial fibrillation patients, 60% of hypertension patients, and 70% of cerebrovascular disease patients were actively managed.
  • Patients with symptomatic vascular disease received more appropriate risk management (72%) than asymptomatic patients (46%).

Conclusions:

  • Despite a significant number of potentially preventable ischemic strokes, there is an encouraging trend towards better control of stroke risk factors.
  • Continued efforts in risk factor management are essential for reducing the burden of ischemic stroke.
