ABSTRACT
BACKGROUND AND PURPOSE:
Cerebral small vessel disease-a major cause of stroke and dementia-is associated with cerebrovascular dysfunction. We investigated whether short-term isosorbide mononitrate (ISMN) and cilostazol, alone or in combination, improved magnetic resonance imaging-measured cerebrovascular function in patients with lacunar ischemic stroke.METHODS:
Participants were randomized to ISMN alone, cilostazol alone, both ISMN and cilostazol, or no medication. Participants underwent structural, cerebrovascular reactivity (to 6% carbon dioxide) and phase-contrast pulsatility magnetic resonance imaging at baseline and after 8 weeks of medication.RESULTS:
Of 27 participants (mean age, 68±7.7; 44% female), 22 completed cerebrovascular reactivity and pulsatility imaging with complete datasets. White matter cerebrovascular reactivity increased in the ISMN (ß=0.021%/mm Hg [95% CI, 0.003-0.040]) and cilostazol (ß=0.035%/mm Hg [95% CI, 0.014-0.056]) monotherapy groups and in those taking any versus no medication (ß=0.021%/mm Hg [95% CI, 0.005-0.037]).CONCLUSIONS:
While limited by small sample size, we demonstrate that measuring cerebrovascular function with magnetic resonance imaging is feasible in clinical trials and that ISMN and cilostazol may improve cerebrovascular function.
