There is a lack of studies on anticoagulant plus antiplatelet therapy for acute ischemic stroke. The present study made a pilot effort to investigate the efficacy and safety of argatroban plus dual antiplatelet therapy (DAPT) in patients with acute posterior circulation ischemic stroke (PCIS). We retrospectively collected patients diagnosed with acute PCIS according to inclusion/exclusion criteria. According to treatment drugs, patients were divided into an argatroban plus DAPT group and a DAPT group. The primary efficacy end point was the proportion of early neurological deterioration (END). The primary safety outcome was symptomatic intracranial hemorrhage. All outcomes were compared between the 2 groups before and after propensity score matching (PSM). A total of 502 patients were enrolled in the study, including 35 patients with argatroban plus DAPT and 467 patients with DAPT. There was a higher National Institutes of Health Stroke Scale (NIHSS) score in the argatroban plus DAPT group than the DAPT group before PSM (3 vs 2, P = .017). Compared with the DAPT group, the argatroban plus DAPT group had no END (before PSM: 0% vs 6.2%, P = .250; after PSM: 0% vs 5.9%, P = .298). Argatroban plus DAPT yielded a significant decrease in the NIHSS score from baseline to 7 days after hospitalization, compared with that of the DAPT group before PSM ( P = .032), but not after PSM ( P = .369). No symptomatic intracranial hemorrhage was found in any patient. A short-term combination of argatroban with DAPT appears safe in acute minor PCIS.

Early Neurological Deterioration

Background and Purpose— In 20% to 30% of patients with lacunar strokes, early neurological deterioration (END) occurs within the first days after stroke onset. However, effective treatment strategies are still missing for these patients. The purpose of this study was to analyze efficacy of dual antiplatelet therapy (DAPT) in patients presenting with END. Methods— Four hundred fifty-eight patients with lacunar strokes and corresponding neuroimaging evidence of lacunar ischemia were retrospectively screened for END, which was defined by deterioration of ≥3 total National Institutes of Health Stroke Scale points, ≥2 National Institutes of Health Stroke Scale points for limb paresis, or documented clinical deterioration within 5 days after admission. Patients with END were treated with DAPT according to in-house standards. Primary efficacy end point was fulfilled if National Institutes of Health Stroke Scale score at discharge improved at least to the score at admission. Secondary end points were Rankin Scale score, further clinical fluctuation, and symptomatic bleeding complications. Results— END occurred in 130 (28%) of 458 patients with lacunar strokes. Ninety-seven (75%) of these patients were treated with DAPT after END, mostly for 5 days. DAPT was associated with improved functional outcome. The primary end point was met in 68% (66) of patients with DAPT compared with 36% (12) of patients with standard treatment ( P =0.0019). Further clinical fluctuations were absent in 79% (77) of patients with DAPT versus 33% (11) of patients without DAPT ( P <0.001). Symptomatic bleeding complications were not observed in any patient. Conclusions— The results demonstrated potential positive effects of DAPT in patients with progressive lacunar strokes.

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.

Branch Atheromatous Disease

IntroductionBranch atheromatous disease (BAD) contributes to small-vessel occlusion in cases of occlusion or stenosis of large calibre penetrating arteries, and it is associated with a higher possibility of early neurological deterioration (END) and recurrent stroke in acute ischaemic stroke. As the pathology of BAD is due to atherosclerosis, we postulate that early intensive medical treatment with dual antiplatelet therapy (DAPT) and high-intensity statins may prevent END and recurrent stroke in acute small subcortical infarction caused by BAD.Methods and analysisIn this prospective, single-centre, open-label, non-randomised, single-arm study using a historical control, we will compare early DAPT and high-intensity statin treatment with a historical control group of patients with BAD who were treated with single antiplatelet therapy without high-intensity statin treatment. Patients will be eligible for enrolment if they are admitted for acute ischaemic stroke within 24 hours, have a National Institutes of Health Stroke Scale (NIHSS) score of 1–8 and are diagnosed with BAD by MRI. Patients will take aspirin, clopidogrel and high-intensity statins (atorvastatin or rosuvastatin) within 24 hours of stroke onset, followed by aspirin or clopidogrel alone from day 22. The primary endpoint is the percentage of patients who develop END within 7 days of stroke onset (defined as an increase in the NIHSS score ≥2 points) and recurrent stroke within 30 days. The total sample sizes will be 138 for the intervention group and 277 for the control group. A historical control group will be drawn from previous prospective observation studies.Ethics and disseminationThe protocol of this study has been approved by the Institutional Review Board of Chang Gung Memorial Hospital (202001386A3). All participants will have to sign and date an informed consent form. The findings arising from this study will be disseminated in peer-reviewed journals and academic conferences.Trial registration numberNCT04824911.

Summary. Background: To assess the impact of short- vs. long-term anticoagulation in addition to standard dual antiplatelet therapy (DAPT) upon endovascular treatment of (sub)acute thrombembolic occlusions of the lower extremity. Patient and methods: Retrospective analysis was conducted on 202 patients with a thrombembolic occlusion of lower extremities, followed by crirical limb ischemia that received endovascular treatment including thrombolysis, mechanical thrombectomy, or a combination of both between 2006 and 2015 at a single center. Following antithrombotic regimes were compared: 1) dual antiplatelet therapy, DAPT for 4 weeks (aspirin 100 mg/d and clopidogrel 75 mg/d) upon intervention, followed by a lifelong single antiplatelet therapy; 2) DAPT plus short term anticoagulation for 4 weeks, followed by a lifelong single antiplatelet therapy; 3) DAPT plus long term anticoagulation for > 4 weeks, followed by a lifelong anticoagulation. Results: Endovascular treatment was associated with high immediate revascularization (> 98 %), as well as overall and amputation-free survival rates (> 85 %), independent from the chosen anticoagulation regime in a two-year follow up, p > 0.05. Anticoagulation in addition to standard antiplatelet therapy had no significant effect on patency or freedom from target lesion revascularization (TLR) 24 months upon index procedure for both thrombotic and embolic occlusions. Severe bleeding complications occurred more often in the long-term anticoagulation group (9.3 % vs. 5.6 % (short-term group) and 6.5 % (DAPT group), p > 0.05). Conclusions: Our observational study demonstrates that the choice of an antithrombotic regime had no impact on the long-term follow-up after endovascular treatment of acute thrombembolic limb ischemia whereas prolonged anticoagulation was associated with a nominal increase in severe bleeding complications.

A P2Y12 inhibitor-based monotherapy after a short period of dual antiplatelet therapy is emerging as a plausible strategy to decrease bleeding events in high-risk patients receiving dual antiplatelet therapy after percutaneous coronary intervention. Ticagrelor With Aspirin or Alone in High-Risk Patients After Coronary Intervention (TWILIGHT), a randomized double-blind trial, tested this approach by dropping aspirin at 3 months and continuing with ticagrelor monotherapy for an additional 12 months. The study enrolled 9,006 patients, of whom 7,119 who tolerated 3 months of dual antiplatelet therapy were randomized after 3 months into two arms: ticagrelor plus placebo and ticagrelor plus aspirin. The primary endpoint of interest, Bleeding Academic Research Consortium type 2, 3, or 5 bleeding, occurred less frequently in the experimental arm (HR 0.56; 95% CI [0.45–0.68]; p<0.001), whereas the secondary endpoint of ischemic events was similar between the two arms (HR 0.99; 95% CI [0.78–1.25]). Transition from dual antiplatelet therapy consisting of ticagrelor plus aspirin to ticagrelor-based monotherapy in high-risk patients at 3 months after percutaneous coronary intervention resulted in a lower risk of bleeding events without an increase in risk of death, MI, or stroke.
