Background and Purpose: Cilostazol, a phosphodiesterase 3’ inhibitor, is used in Asia-Pacific countries for stroke prevention, but rarely used elsewhere. In addition to weak antiplatelet effects, it stabilizes endothelium, aids myelin repair and astrocyte-neuron energy transfer in laboratory models, effects that may be beneficial in preventing small vessel disease progression. Methods: A systematic review and meta-analysis of unconfounded randomized controlled trials of cilostazol to prevent stroke, cognitive decline, or radiological small vessel disease lesion progression. Two reviewers searched for papers (January 1, 2019 to July 16, 2019) and extracted data. We calculated Peto odds ratios (ORs) and 95% CIs for recurrent ischemic, hemorrhagic stroke, death, adverse symptoms, with sensitivity analyses. The review is registered (CRD42018084742). Results: We included 20 randomized controlled trials (n=10 505), 18 in ischemic stroke (total n=10 449) and 2 in cognitive impairment (n=56); most were performed in Asia-Pacific countries. Cilostazol decreased recurrent ischemic stroke (17 trials, n=10 225, OR=0.68 [95% CI, 0.57–0.81]; P <0.0001), hemorrhagic stroke (16 trials, n=9736, OR=0.43 [95% CI, 0.29–0.64]; P =0.0001), deaths (OR=0.64 [95% CI, 0.49–0.83], P <0.0009), systemic bleeding (n=8387, OR=0.73 [95% CI, 0.54–0.99]; P =0.04), but increased headache and palpitations, compared with placebo, aspirin, or clopidogrel. Cilostazol reduced recurrent ischemic stroke more when given long (>6 months) versus short term without increasing hemorrhage, and in trials with larger proportions (>40%) of lacunar stroke. Data were insufficient to assess effects on cognition, imaging, functional outcomes, or tolerance. Conclusions: Cilostazol appears effective for long-term secondary stroke prevention without increasing hemorrhage risk. However, most trials related to Asia-Pacific patients and more trials in Western countries should assess its effects on cognitive decline, functional outcome, and tolerance, particularly in lacunar stroke and other presentations of small vessel disease.

Background: Association between high homocysteine level and cerebral small-vessel disease has been implicated in cross-sectional studies, but results from longitudinal studies have been less clear. The aim of this study was to investigate whether homocysteine level at 3-months poststroke relates to the occurrence of white matter changes (WMC), the surrogate of cerebral small-vessel disease. We also investigated whether it relates to the prognosis after ischemic stroke regarding the risk of dementia at 3-months and mortality in long-term follow-up. Methods: A total of 321 consecutive acute ischemic stroke patients aged 55 to 85 were included in the study and followed up to 12 years. Plasma homocysteine level and occurrence of WMC in MRI were measured 3 months poststroke and dementia according to DSM-III was evaluated at the same time. Findings: The median homocysteine level was 13.50 μmol/l (interquartile range [IQR] 10.60-18.50 μmol/l). Total of 81 patients (25.2%) had homocysteine level above 18.50 μmol/l. In logistic regression analysis, homocysteine level above 18.50 μmol/l was not associated with severe WMC nor with dementia at 3 months poststroke. In Kaplan-Meier analysis, homocysteine level above 18.50 μmol/l was not associated with survival in 12-year follow-up. For further analysis, the group was divided in quartiles according to homocysteine level. The quartiles did not differ in occurrence of severe WMC at baseline, in the risk of dementia at 3 months, nor in the risk of mortality in 12-year follow-up. Interpretation: In our poststroke cohort homocysteine level is not associated with WMC. Further, it does not relate to impaired prognosis manifested as dementia at 3 months or mortality in 12-year follow-up.

The Impact

Background: Intracranial atherosclerotic stenosis (ICAS) and small vessel disease (SVD) may coexist. We investigated the frequency and risk factors for SVD in SAMMPRIS patients and the impact of SVD on stroke recurrence in the medical arm of the trial. Methods: Of 451 patients enrolled in SAMMPRIS, 313 had baseline brain MRIs read centrally for SVD. SVD was defined by any of the following: old lacunar infarction, Fazekas score of 2-3 for white matter hyperintensities, or microbleeds. We compared risk factors in patients with vs. without SVD using Fisher’s exact test (for percentages), independent groups t test (for means) or Wilcoxon rank sum test (for medians), and compared the survival curves of patients with vs. without SVD in the medical arm for ischemic stroke in the territory of the stenotic artery and any ischemic stroke using the logrank test. Results: Of the 313 patients, 161 (51.4%) had SVD on the baseline MRI. Variables that were significantly (p<0.05) higher in patients with SVD were age, diabetes, lipid disorder, baseline SBP, coronary disease, and old infarct in the territory. The Kaplan-Meier curves in the figure show that patients with SVD were at significantly higher risk of any ischemic stroke (p = 0.048) but not stroke in the territory (p = 0.10) compared with patients without SVD. Conclusion: SVD in patients with ICAS is common, especially in patients who are older, diabetic, hyperlipidemic, and have higher SBP. Patients with ICAS and coexistent SVD are at higher risk of any ischemic stroke but may not be at higher risk for stroke in the territory.
