Implication

Prospective cohort study reveals diverse stroke mechanisms in lacunar infarction patients, highlighting that recurrent events extend beyond small vessel occlusions.

Key Points

To identify the presumed pathogenetic mechanisms and clinical risk factors associated with recurrent stroke in patients presenting with lacunar infarction.
Followed a prospective cohort of 81 patients with clinical and MRI-confirmed lacunar infarction for a median duration of 48 months.
Investigated recurrent stroke cases using CT, contrast-enhanced MRI, and systematic diagnostic evaluations for large-artery disease and cardioembolic sources.
During follow-up, 20 patients (24.7%) experienced 27 recurrent strokes (24 ischemic, 3 hemorrhagic) with an annual recurrence risk of 6.8%, and 9 patients (11.1%) died.
Univariate analysis identified age as the only risk factor significantly associated with stroke recurrence.
Among 24 recurrent ischemic strokes, 16 were attributed to small penetrating artery occlusions, 6 to cortical infarcts, 1 to presumed cerebral amyloid angiopathy, and 1 to retinal infarction, with large-artery disease identified in 4 patients.
