Hypertension is linked to specific ischemic stroke types, particularly lacunar infarcts and atherothrombotic infarction. Understanding these risk factors improves stroke prediction and management.

Area of Science:

  • Neurology
  • Cardiovascular Medicine
  • Epidemiology

Background:

  • Hypertension is a major cardiovascular risk factor.
  • Ischemic stroke subtypes have distinct risk factor profiles.
  • Understanding hypertension's role in different stroke types is crucial for targeted prevention.

Purpose of the Study:

  • To compare risk factors, clinical features, neuroimaging, and outcomes in hypertensive versus non-hypertensive ischemic stroke patients.
  • To identify independent predictors of hypertensive ischemic stroke.
  • To elucidate the specific associations between hypertension and ischemic stroke subtypes.

Main Methods:

  • Bivariate analysis comparing features of hypertensive (n=768) and non-hypertensive (n=705) ischemic stroke patients.

  • Multivariate analysis to determine independent predictors of hypertensive ischemic stroke.
  • Assessment of clinical data, neuroimaging, and patient outcomes.

    • Main Results:

    • Atherothrombotic infarction and lacunar infarct were more common in hypertensive patients.
    • Hypertensive patients showed higher prevalence of older age, previous cerebral infarction, hyperlipidemia, acute stroke onset, lacunar syndrome, and pons topography.
    • Multivariate analysis revealed lacunar syndrome, female gender, and previous infarction were directly associated with hypertensive ischemic stroke; advanced age (≥85) and valvular heart disease were inversely associated.

    Conclusions:

    • Hypertension is a significant risk factor primarily for lacunar and atherothrombotic infarction (small- and large-artery disease).
    • Specific clinical features and demographics differentiate hypertensive from non-hypertensive ischemic stroke.
    • These findings aid in refining risk stratification and understanding the pathophysiology of hypertension-related ischemic stroke.
