BACKGROUND/AIMS We examined the effects of cilostazol on mitogen-activated protein kinase (MAPK) activity and its relationship with cilostazol-mediated protection against apoptosis in lipopolysaccharide (LPS)-treated endothelial cells. METHODS Human umbilical vein endothelial cells (HUVECs) were exposed to LPS and cilostazol with and without specific inhibitors of MAPKs; changes in MAPK activ...

RATIONALE AND AIMS Monotherapy with antiplatelet agents is only modestly effective in secondary prevention of ischemic stroke (IS), particularly in patients with multiple risk factors such as cervicocephalic arterial stenosis, diabetes, and hypertension. While dual antiplatelet therapy (DAPT) with aspirin and clopidogrel reduced IS recurrence, particularly in the early stages after IS, it incre...

Cilostazol, a potent inhibitor of type 3 phosphodiesterase (PDE3), has recently been reported to exert neuroprotective effects during acute cerebral ischemic injury. These effects are, at least in part, mediated by the inhibition of oxidative cell death. However, the effects of cilostazol on glucose metabolism in brain cells have not been determined. In the present study, we examined the effect...

This study investigated the effect of cilostazol on proangiogenesis functions in human early endothelial progenitor cells (EPCs) in vitro and the therapeutic implication of hybrid therapy with cilostazol and human early EPCs in vivo. Cilostazol significantly increased colony-forming units and enhanced differentiation of EPCs toward endothelial lineage. Treatments resulted in antiapoptotic effec...

BACKGROUND Effective medication is limited for the relief of intermittent claudication, a common manifestation of arterial occlusive disease. Cilostazol is a potent inhibitor of platelet aggregation with vasodilation effects. OBJECTIVE To evaluate the safety and efficacy of cilostazol for the treatment of intermittent claudication. METHODS Thirty-seven outpatient vascular medicine clinics a...

BACKGROUND The Cilostazol Stroke Prevention Study 2 (CSPS 2) showed that cilostazol significantly reduced the risk of stroke by 25.7% relative to aspirin, with significantly fewer hemorrhagic events, in patients with prior ischemic stroke, excluding cardioembolic stroke. However, whether the benefit of cilostazol is sustained in patients with a high risk of bleeding has not been examined. MET...

BACKGROUND AND PURPOSE Although long-term treatment with the oral anticoagulant warfarin is widely used to prevent cardioembolic ischemic stroke, it has been reported that warfarin can exacerbate hemorrhagic transformation (HT) after cerebral ischemia. We investigated whether cilostazol, a phosphodiesterase-III inhibitor, suppressed the warfarin-induced HT after cerebral ischemia in mice. MET...

Background. Peripheral arterial disease (PAD) and its relevant complications are more common in hemodialysis (HD) patients, while the evidence regarding antiplatelet therapy in CKD patients is scarce. We retrospectively analyzed the efficacy of cilostazol on outcomes in HD patients with asymptomatic PAD (aPAD). Methods. This cohort study enrolled 217 HD patients (median follow-up time: 5.75 yea...

AIM Cilostazol is clinically used as an inhibitor of platelet aggregation. Although several reports have demonstrated its anti-inflammatory effect, its effect on monocytes and their adhesive interaction to vascular endothelium remains unclear. We thus examined the potential role of cilostazol towards monocyte endothelial interaction under physiological flow conditions. METHODS THP-1 cells, a ...

Objective: In our search for a new augmentation therapy for stroke patients, we administered cilostazol, an antiplatelet agent. Subjects: The patients suffered from mild hemiparesis or cognitive disorder showing reduced cerebral perfusion in the prefrontal cortex. Methods: We evaluated the functional cerebral blood flow (CBF) before and after the administration of cilostazol using near-infrared...
