    Abstract: Hypothesis: The aim of the present study was to investigate the efficacy and safety of antiplatelet (aspirin plus cilostazol) dual therapy for non-cardioembolic stroke patients within 48 h of symptom onset. Methods: ADS is an investigator initiated, a prospective, multicenter (34 hospitals in Japan), randomized, and an aspirin-controlled study. Acute stroke patients with non-cardioembolic stroke within 48 hours of onset were studied. Only patients with preadmission mRS score 0-2 were included. Subjects were randomly allocated to the combination therapy with aspirin 81-200mg plus cilostazol 200mg (Dual group) and the single therapy with aspirin 81-200mg (Aspirin group) for 14 days. After the 14 days, all patients took the cilostazol 200mg for 3 months. Primary outcomes include 1) the neurological worsening within 14 day of onset; and 2) the rates of transient ischemic attack (TIA), stroke recurrence, intracerebral hemorrhage (ICH), subarachnoid hemorrhage (SAH) within 14 days of onset. Secondary outcome included mRS score at 3 months after stroke. Results: 1,201 patients (796 [66%] men; median age [interquartile range] , 69 [61-77] years) were randomized 1:1 to either the dual group or the aspirin group. Initial National Institutes of Health Stroke Scale score was similar as 2 (1-4) in both groups (p=0.617). As a primary outcome, the neurological worsening within 14 days was similarly observed in the dual and in the aspirin group (10.5% vs. 9.7%, P=0.701). The rates of TIA and stroke recurrence in the dual and in the aspirin group were also similar as 0.2% vs. 0.2% (p=1.000), and 1.2% vs. 1.3% (p=1.000), respectively. As a safety outcome, each group had one patient with ICH (0.2% vs. 0.2%, p=1.000). Only 1 patient (0.2%) in the dual group complained of SAH within 14 days of stroke onset, though it was asymptomatic (p=1.000). Regarding the secondary outcome, although preadmission mRS score of 0 was infrequent in the dual group (84% vs. 89%, p=0.054), the rate of mRS 0-1 at 3 months seemed to be frequent in the dual group than aspirin group (69% vs. 64% p=0.075). Conclusions: Dual antiplatelet therapy using cilostazol and aspirin does not reduce the rate of short-term neurological worsening. However, this combined therapy may improve the clinical outcome at 3 months of onset.

    Abstract WP115: Cilostazol Addition to Aspirin Does Not Alter the Short-Term Neurological Outcome in Each Clinical Subtype of Acute Stroke

    Abstract: Hypothesis: Our previous study, ADS reported that dual antiplatelet therapy (DAPT) using cilostazol and aspirin did not reduce the rate of short-term neurological worsening in non-cardioembolic stroke patients. The aim of the present study is to investigate 1) whether the impact of cilostazol addition to aspirin differ among each stroke subtype, and 2) factors associated with neurological deterioration and/or stroke recurrence in order to find therapeutic target. Methods: This is a retrospective analysis using the ADS databank. Neurological worsening and the rates of stroke recurrence within 14 day of onset were evaluated. Stroke subtype included large-artery atherosclerosis (LAA), lacunae infarct (LI), branch atheromatous disease (BAD), other, and undetermined. Results: Data on 1,160 patients (773 [67%] men; median age, 69 [61-77] years, NIHSS score was 2 [1-4]) were analyzed. At discharge, 167 (14%) were diagnoses as having LAA; LI, 532 (46%); BAD, 173 (15%); other, 132 (11%); and undetermined, 156 (14%). Neurological deterioration and/or recurrence were seen in 130 (11%) patients, and the rates were not different between patients treated with DAPT and aspirin in any stroke subtypes: LAA, 19% (DAPT) vs. 11% (aspirin alone), (p=0.185); LI, 4% vs. 3% (p=0.645); BAD, 33% vs.34%, (p=0.872), other, 8% vs.14% (p=0.272); undetermined, 13% vs. 8% (p=0.301). When we evaluated factors related to the deterioration/recurrence, age (p 〈 0.001), NIHSS score (p 〈 0.001), systolic and diastolic blood pressures (p 〈 0.001, and 0.025), whiter matter change (p=0.002), large infarcts 〉 1.5cm (p 〈 0.001), and intracranial stenosis/occlusion (p 〈 0.001) were found. Multivariate regression analysis revealed older age (p=0.003), systolic blood pressure (p=0.013), larger infarct (p=0.001), intracranial stenosis/occlusion (p 〈 0.035) were the independent factors associated with neurological deterioration/stroke recurrence. Conclusions: Dual antiplatelet therapy using cilostazol and aspirin does not reduce the rate of short-term neurological worsening in each clinical stroke subtype. Improvement of hyperacute therapy targeting the elder patients with elevated blood pressure, large infarct and intracranial stenosis/occlusion should be required.

    Abstract WP256: Administration of Cilostazol Clarifies the Burden Atrial Fibrillation in Non-Cardioembolic Stroke
    Ovid Technologies (Wolters Kluwer Health) ; 2019

    Abstract: Introduction: The survey of atrial fibrillation (AF) is routinely recommended in acute stroke case, even in patients without AF on admission, because the AF leads to a sever stroke. Cilostazol is often used for stroke patients without AF in Japan; however, it has the adverse events of palpitation due to the vessels dilatation by increased nitric oxide. We hypothesized that administration of cilostazol may clarify the burden AF in stroke patients without AF. Methods: From our prospective randomized control study, (randomized to dual antiplatelet therapy using cilostazol and aspirin or aspirin alone targeted patients for non-cardioembolic stroke [ADS]), patients assessed the presence of AF were retrospectively analyzed. Presence of AF was detected using ECG monitoring and Holter ECG. All patients were divided into the AF group and the non-AF group and imaging and laboratory findings were compared between the 2 groups. Multivariate regression analysis was conducted to evaluate the independent factors related to new AF. Results: 1194 patients (793 [66%] men; median age [IQR] of 69 [61-77] years, NIHSS score 2 [1-4] , onset-to-admission 10.8 [4.7-20.5] hours) patients were included. AF was newly detected in 41 patients (3 by ECG, 21 by the ECG monitoring and 17 by the Holter ECG) during hospitalization. Patients randomized to the combined cilostazol and aspirin therapy frequently had the AF than those to aspirin alone (29/596 [5%] vs. 12/598 [2%], p=0.007). AF group was older than the non-AF group (76 [72-82] vs. 68 [60-77] years, p 〈 0.001). NIHSS score was similar between AF and non-AF group (5 [3-12] vs. 4 [2-6] p=0.062). Serum brain natriuretic peptide (BNP) level was higher in AF group (65.9 [31.7-145.5] vs. 25.6 [13.1-52.5] ng/ml. p 〈 0.001). Regarding imaging findings, cardio-thoracic ratio (CTR) was elevated (p 〈 0.001), multiple infarcts was frequent (p=0.003) and the infarcts size was larger ( 〉 1.5cm) (p 〈 0.001) in AF group. By multivariate regression analysis, cilostazol administration was the independent factor for new AF detection (odds ratio 2.81, 95%CI: 1.30-6.09, p=0.009) adjusting for age, infarct size and number, CTR, BNP, and NIHSS score. Conclusion: Administration of cilostazol increases the detectability of AF in acute non-cardioembolic stroke.

    Abstract: The aim of the present study was to investigate the efficacy and safety of antiplatelet (aspirin plus cilostazol) dual therapy for patients with noncardioembolic stroke within 48 hours of symptom onset. Methods and Results The ADS (Acute Aspirin Plus Cilostazol Dual Therapy for Non‐Cardiogenic Stroke Patients Within 48 Hours of Symptom Onset ) study is an investigator‐initiated, prospective, multicenter (34 hospitals in Japan), randomized, open‐label, and aspirin‐controlled trial. Acute stroke patients with noncardioembolic stroke within 48 hours of onset were studied. The subjects were randomly allocated to combination therapy with aspirin 81 to 200 mg plus cilostazol 200 mg (dual group) and single therapy with aspirin 81 to 200 mg (aspirin group) for 14 days. After the 14 days, all patients took the cilostazol 200 mg for 3 months. A primary efficacy outcome was defined as any one of the following occurring (neurological deterioration, symptomatic stroke recurrence, or transient ischemic attack) within 14 days. A primary safety outcome included intracerebral hemorrhage and subarachnoid hemorrhage. Between May 2011 and June 2017, 1201 patients (796 [66%] men; median age, 69 [61–77] years) randomized 1:1 to either the dual group or the aspirin group were analyzed. Initial National Institutes of Health Stroke Scale score was 2 (1–4) in both groups ( P =0.830). A primary efficacy outcome was observed in 11% in the dual group and 11% in the aspirin group ( P =0.853). A primary safety outcome occurred in 2 (0.3%) in the dual group and in 1 (0.2%) in the aspirin group ( P =0.624). Conclusions Dual antiplatelet therapy using cilostazol and aspirin was safe but did not reduce the rate of short‐term neurological worsening.
