Identifying risk factors for ischemic stroke recurrence is crucial. This study found that elevated blood pressure, abnormal CT scans, and diabetes increase recurrence risk, while unknown causes and low diastolic blood pressure are associated with lower risk.

Area of Science:

  • Neurology
  • Epidemiology
  • Cardiovascular Medicine

Background:

  • Stroke recurrence poses a significant public health challenge.
  • Understanding risk factors is essential for effective secondary prevention strategies.

Purpose of the Study:

  • To identify predictors of ischemic stroke recurrence.
  • To determine factors associated with both increased and decreased risk of recurrent stroke.

Main Methods:

  • Prospective study of 1,273 ischemic stroke patients.
  • Median follow-up period of 13 months.
  • Analysis of clinical data, computed tomography findings, and medical history.

Main Results:

  • The 2-year cumulative stroke recurrence rate was 14.1%.

  • Elevated blood pressure, abnormal initial CT scans, and history of diabetes mellitus were associated with higher recurrence risk.
  • Infarct of unknown cause was linked to a lower recurrence risk compared to defined mechanisms like lacunes, embolism, or atherosclerosis.

    • Conclusions:

    • Low diastolic blood pressure, absence of prior stroke history, no history of diabetes mellitus, and infarct of unknown cause are associated with the lowest risk of stroke recurrence.
    • These findings can inform personalized secondary stroke prevention strategies.
