Dual versus mono antiplatelet therapy in mild-to-moderate stroke during hospitalization.

ABSTRACT:

Objective

Subsequent vascular events are common after acute ischemic stroke during hospitalization. This study aimed to analyze the effectiveness of combination therapy with clopidogrel and aspirin among mild-to-moderate ischemic stroke patients treated within 72 h on the basis of a high-intensity dose of statins.

Methods

In a retrospective and multicenter cohort study, acute (within 72 h of onset) mild-to-moderate stroke patients were divided into aspirin and clopidogrel-aspirin groups on the basis of a high-intensity dose of statin therapy. The primary outcome was compound vascular events during hospitalization. Cox's proportional hazards model was used to assess differences, with the study center as a random effect.

Results

Among the 506 patients meeting the eligibility criteria, all subjects received a high-intensity dose of statins, including 20 mg rosuvastatin or 40 mg atorvastatin while in the hospital. In an unadjusted analysis, compound vascular events occurred in 7.2% of patients in the clopidogrel-aspirin group compared with 13.7% of those in the aspirin group (p = 0.022). In a Cox proportional hazards regression analysis, clopidogrel-aspirin was associated with a lower risk of compound vascular events (hazard ratio [95% CI], 0.47 [0.25-0.87]; p = 0.017) and ischemic vascular events (p = 0.008). Moderate and severe hemorrhage occurred in four patients (1.07%) in the clopidogrel-aspirin group and three patients (2.30%) in the aspirin group (p = 0.626).

Interpretation

In this study based on high-intensity statin therapy, clopidogrel-aspirin reduced the risk of compound vascular events and did not increase the risk of hemorrhage during patients' hospitalization after mild-to-moderate ischemic stroke within 72 h.

Project description:BackgroundShort-term dual antiplatelet therapy (DAPT) reduces early stroke recurrence after mild noncardioembolic ischemic stroke (NCIS). We aim to evaluate temporal trends and determinants of DAPT prescription after mild NCIS in the Florida Stroke Registry, a statewide registry across Get With The Guidelines-Stroke participating hospitals.MethodsIn this cross-sectional analysis of a cohort study, we included patients with mild NCIS (National Institutes of Health Stroke Scale score ≤3) who were potentially eligible for DAPT across 168 Florida Stroke Registry participating hospitals between January 2010 and September 2022. Using antiplatelet prescription as the dependent variable (DAPT versus single antiplatelet therapy), we fit logistic regression models adjusted for patient-related factors, hospital-related factors, clinical presentation, vascular risk factors, and ischemic stroke subtype, to obtain adjusted odds ratios (aORs) with 95% CIs.ResultsFrom 283 264 Florida Stroke Registry ischemic stroke patients during the study period, 109 655 NCIS were considered eligible. Among these, 37 058 patients with National Institutes of Health Stroke Scale score >3 were excluded, resulting in a sample of 72 597 mild NCIS (mean age 68±14 years; female 47.3%). Overall, 24 693 (34.0%) patients with mild NCIS were discharged on DAPT and 47 904 (66.0%) on single antiplatelet therapy. DAPT prescription increased from 25.7% in 2010 to 52.8% in 2022 (β/year 2.5% [95% CI, 1.5%-3.4%]). Factors associated with DAPT prescription were premorbid antiplatelet therapy (aOR, 4.66 [95% CI, 2.20-9.88]), large-artery atherosclerosis (aOR, 1.68 [95% CI, 1.43-1.97]), diabetes (aOR, 1.29 [95% CI, 1.13-1.47]), and hyperlipidemia (aOR, 1.24 [95% CI, 1.10-1.39]), whereas female sex (aOR, 0.83 [95% CI, 0.75-0.93]), being non-Hispanic Black patients (compared with non-Hispanic White patients; aOR, 0.78 [95% CI, 0.68-0.90]), admission to a Thrombectomy-capable Stroke Center (compared with Comprehensive Stroke Center; aOR, 0.78 [95% CI, 0.66-0.92]), time-to-presentation 1 to 7 days from last seen well (compared with <24 h; aOR, 0.86 [95% CI, 0.76-0.96]), and small-vessel disease stroke (aOR, 0.81 [95% CI, 0.72-0.94]) were associated with not receiving DAPT at discharge.ConclusionsDespite a temporal trend increase in DAPT prescription after mild NCIS, we found substantial underutilization of evidence-based DAPT associated with significant disparities in stroke care.

Project description:BackgroundA recent study shows that dual antiplatelet therapy with clopidogrel plus aspirin is superior to aspirin monotherapy for minor stroke, which is defined as a National Institutes of Health Stroke Scale (NIHSS)score of ≤3. However, acute mild-moderate ischaemic stroke (4≤NIHSS≤10) still needs aggressive antiplatelet intervention to prevent deterioration and recurrence of stroke. The efficacy and safety of dual antiplatelet therapy versus aspirin monotherapy in the population are not clear. A multicentre clinical trial is designed to evaluate the efficacy and safety of clopidogrel plus aspirin therapy versus aspirin monotherapy within 48 hours of symptom onset of mild-moderate ischaemic stroke.Methods/designThe study is a randomised, open-label, multicentre, prospective trial with a target enrolment of 2700 patients from 60 centres in Northeast China. A treatment allocation identification number to each enrolled patient will be provided by a random number generator. The follow-up time for the clopidogrel plus aspirin and aspirin monotherapy groups is 90 days. The primary efficacy endpoint is a stroke progression event, which is defined as ≥4 point increase in the NIHSS score in 48 hours. The second efficacy endpoints include new ischaemic stroke within 90 days, change in the NIHSS score within 14 days, modified Rankin Scale score on day 90 and other vascular or death events within 90 days. The safety endpoints include mucocutaneous haemorrhage, organ haemorrhage and intracranial haemorrhage, adverse events and severe adverse events. χ2 test, t-test (or Mann-Whitney test), survival analysis and Cox proportional hazards models will be conducted. The findings of the study may provide an important evidence for clinical practice for these patients.DiscussionThe trial will be conducted under a rational design and will provide valuable evidence on the appropriate treatment for this population.Ethics and disseminationThe study was reviewed and approved by the Ethics Committee of the General Hospital of Shen-Yang Military Region (no K(2016) 6).Trial registration numberNCT02869009; Pre-results.
