Background and Purpose— The role of aspirin plus clopidogrel (A+C) therapy compared with aspirin monotherapy in patients presenting with acute ischemic stroke (IS) or transient ischemic attack remains uncertain. We conducted this study to determine the optimal period of efficacy and safety of A+C compared with aspirin monotherapy. Methods— Ten randomized controlled trials (15 434 patients) were selected using MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials (CENTRAL) (inception June 2018) comparing A+C with aspirin monotherapy in patients with transient ischemic attack or IS. The primary efficacy outcome was recurrent IS, and the primary safety outcome was major bleeding. The secondary outcomes were major adverse cardiovascular events (composite of stroke, myocardial infarction, and cardiovascular mortality) and all-cause mortality. We stratified analysis based on the short- (≤1 month), intermediate- (≤3 month), and long-term (>3 month) A+C therapy. Effects were estimated as relative risk (RR) with 95% CI. Results— A+C significantly reduced the risk of recurrent IS at short-term (RR, 0.53; 95% CI, 0.37–0.78) and intermediate-term (RR, 0.72; 95% CI, 0.58–0.90) durations. Similarly, major adverse cardiovascular event was significantly reduced by short-term (RR, 0.68; 95% CI, 0.60–0.78) and intermediate-term (RR, 0.76; 95% CI, 0.61–0.94) A+C therapy. However, long-term A+C did not yield beneficial effect in terms of recurrent IS (RR, 0.81; 95% CI, 0.63–1.04) and major adverse cardiovascular events (RR, 0.87; 95% CI, 0.71–1.07). Intermediate-term (RR, 2.58; 95% CI, 1.19–5.60) and long-term (RR, 1.87; 95% CI, 1.36–2.56) A+C regimens significantly increased the risk of major bleeding as opposed to short-term A+C (RR, 1.82; 95% CI, 0.91–3.62). Excessive all-cause mortality was limited to long-term A+C (RR, 1.45; 95% CI, 1.10–1.93). Conclusions— Short-term A+C is more effective and equally safe in comparison to aspirin alone in patients with acute IS or transient ischemic attack.

Background and Purpose: Many patients with ischemic stroke present with multiple comorbidities that threaten survival and recovery. This study sought to determine the risks of adverse long-term stroke outcomes associated with multimorbid diabetes mellitus and depression. Methods: Retrospective analysis of prospectively collected data on consecutive patients without premorbid dementia admitted from the community for a first-ever acute ischemic stroke to comprehensive stroke centers across Ontario, Canada (2003–2013). Premorbid histories of diabetes mellitus and depression were ascertained within 5 years before stroke admission. Adjusted hazard ratios (aHR [95% CI]) of admission to long-term care, incident dementia, readmission for stroke or transient ischemic attack and all-cause mortality, over time among those discharged back into the community poststroke. Results: Among 23 579 stroke admissions, n=20 201 were discharged back into the community. Diabetes mellitus and depression were associated with synergistic hazards of admission to long-term care (X 2 =5.4; P =0.02) over a median follow-up of 5.6 years. This interaction was observed among women specifically; depression multimorbidity showed particularly high hazards of admission to long-term care (aHR Depression =1.57 [1.24–1.98]) and incident dementia (aHR Depression =1.85 [1.40–2.44]) among women with diabetes mellitus. In the whole cohort, diabetes mellitus and depression were associated individually with long-term care admission (aHR Diabetes =1.20 [1.12–1.29]; aHR Depression =1.19 [1.04–1.37]), incident dementia (aHR Diabetes =1.14 [1.06–1.23]; aHR Depression =1.27 [1.08–1.49]), stroke/transient ischemic attack readmission (aHR Diabetes =1.18 [1.10–1.26]; aHR Depression =1.24 [1.07–1.42]), and all-cause mortality (aHR Diabetes =1.29 [1.23–1.36]; aHR Depression =1.16 [1.05–1.29]). Conclusions: The risks of dementia and needing long-term care in the years after surviving a stroke were particularly elevated among women when premorbid diabetes mellitus and depression occurred together. Long-term stroke recovery strategies might target high-risk patients with mood and metabolic multimorbidity.

Abstract Background To manage the risk factors and to improve clinical outcomes, patients with stroke commonly receive multiple cardiovascular medications. However, there is a lack of evidence on the optimum combination of medication therapy in the primary care setting after ischemic stroke. Therefore, this study aimed to investigate the effect of multiple cardiovascular medications on long-term survival after an incident stroke event (ischemic stroke or transient ischemic attack (TIA)). Methods This study consisted of 52,619 patients aged 45 and above with an incident stroke event between 2007 and 2016 in The Health Improvement Network database. We estimated the risk of all-cause mortality in patients with multiple cardiovascular medications versus monotherapy using a marginal structural model. Results During an average follow-up of 3.6 years, there were 9230 deaths (7635 in multiple cardiovascular medication groups and 1595 in the monotherapy group). Compared with patients prescribed monotherapy only, the HRs of mortality were 0.82 (95% CI 0.75–0.89) for two medications, 0.65 (0.59–0.70) for three medications, 0.61 (0.56–0.67) for four medications, 0.60 (0.54–0.66) for five medications and 0.66 (0.59–0.74) for ≥ six medications. Patients with any four classes of antiplatelet agents (APAs), lipid-regulating medications (LRMs), angiotensin-converting enzyme inhibitors (ACEIs)/angiotensin receptor blockers (ARBs), beta-blockers, diuretics and calcium channel blockers (CCBs) had the lowest risk of mortality (HR 0.51, 95% CI 0.46–0.57) versus any one class. The combination containing APAs, LRMs, ACEIs/ARBs and CCBs was associated with a 61% (95% CI 53–68%) lower risk of mortality compared with APAs alone. Conclusion Our results suggested that combination therapy of four or five cardiovascular medications may be optimal to improve long-term survival after incident ischemic stroke or TIA. APAs, LRMs, ACEIs/ARBs and CCBs were the optimal constituents of combination therapy in the present study.

Background and Purpose: Urgent assessment aimed at reducing stroke risk after transient ischemic attack or minor stroke is cost-effective over the short-term. However, it is unclear if the short-term impact is lost on long-term follow-up, with recurrent events being delayed rather than prevented. By 10-year follow-up of the EXPRESS study (Early Use of Existing Preventive Strategies for Stroke), previously showing urgent assessment reduced 90-day stroke risk by 80%, we determined whether that early benefit was still evident long-term for stroke risk, disability, and costs. Methods: EXPRESS was a prospective population-based before (phase 1: April 2002–September 2004; n=310) versus after (phase 2: October 2004–March 2007; n=281) study of the effect of early assessment and treatment of transient ischemic attack/minor stroke on early recurrent stroke risk, with an external control. This report assesses the effect on 10-year recurrent stroke risk, functional outcomes, quality-of-life, and costs. Results: A reduction in stroke risk in phase 2 was still evident at 10 years (55/23.3% versus 82/31.6%; hazard ratio=0.68 [95% CI, 0.48–0.95]; P =0.024), as was the impact on risk of disabling or fatal stroke (17/7.7% versus 32/13.1%; hazard ratio=0.54 [0.30–0.97]; P =0.036). These effects were due to maintenance of the early reduction in stroke risk, with neither additional benefit nor rebound catch-up after 90 days (post-90 days hazard ratio=0.88 [0.65–1.44], P =0.88; and hazard ratio=0.83 [0.42–1.65], P =0.59, respectively). Disability-free life expectancy was 0.59 (0.03–1.15; P =0.043) years higher in patients in phase 2, as was quality-adjusted life expectancy (0.49 [0.03–0.95]; P =0.036). Overall, 10-year costs were nonsignificantly higher in patients attending the phase 2 clinic ($1022 [-3865–5907]; P =0.66). The additional cost per quality-adjusted life year gained in phase 2 versus phase 1 was $2103, well below current cost-effectiveness thresholds. Conclusions: Urgent assessment and treatment of patients with transient ischemic attack or minor stroke resulted in a long-term reduction in recurrent strokes and improved outcomes, with little atrophy of the early benefit over time, representing good value for money even with a 10-year time horizon. Our results suggest that other effective acute treatments in transient ischemic attack/minor stroke in the short-term will also have the potential to have long-term benefit.
