<b><i>Introduction:</i></b> There are a limited number of studies investigating the relationship between the degree of liver fibrosis and the long-term prognosis, especially ischemic stroke (IS) recurrence, in first-ever IS or transient ischemic attack (TIA). <b><i>Objective:</i></b> We investigated whether there are differences in the long-term all-cause and cardiovascular mortalities and IS recurrence based on the degree of liver fibrosis in first-ever IS or TIA. <b><i>Methods:</i></b> This analysis included 2,504 patients with first-ever IS or TIA recruited from a prospective stroke cohort. Liver fibrosis was predicted using the fibrosis-4 (FIB-4) index, and advanced fibrosis was defined as an FIB-4 index of &#x3e;3.25. Using Cox regression models, we compared the all-cause and cardiovascular mortalities and IS recurrence. As measures for the additive predictive value of the FIB-4 index for prediction of all-cause mortality, the integrated area under the receiver operating characteristic curve (iAUC), net reclassification improvement (NRI), and integrated discrimination improvement (IDI) were used. <b><i>Results:</i></b> There were 231 (9.2%) patients with advanced fibrosis. During a median follow-up of 1.2 years, the cumulative all-cause and cardiovascular mortalities were 6.4 and 1.9%, and IS recurrence was observed in 5.3%. The advanced fibrosis was associated with an increased risk of all-cause mortality (hazard ratio [HR] = 3.98, 95% confidence interval [CI] = 2.40–6.59), cardiovascular mortality (HR = 4.48, 95% CI = 1.59–12.65), and IS recurrence (HR = 1.95, 95% CI = 1.05–3.65). Adding the FIB-4 index to the model consisting of traditional cardiovascular risk factors improved the predictive accuracy for all-cause mortality as measured using the iAUC (from 0.7594 to 0.7729) and for all-cause mortality at 1 year as measured using the NRI (38.6%) and IDI (0.037). <b><i>Conclusions:</i></b> The burden of liver fibrosis is associated with unfavorable long-term prognosis, including recurrent IS, in first-ever IS or TIA.

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.

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 Trimethyllysine, a trimethylamine N‐oxide precursor, has been identified as an independent cardiovascular risk factor in acute coronary syndrome. However, limited data are available to examine the role of trimethyllysine in the population with stroke. We aimed to examine the relationship between plasma trimethyllysine levels and stroke outcomes in patients presenting with ischemic stroke or transient ischemic attack. Methods and Results Data of 10 027 patients with ischemic stroke/transient ischemic attack from the CNSR‐III (Third China National Stroke Registry) and 1‐year follow‐up data for stroke outcomes were analyzed. Plasma levels of trimethyllysine were measured with mass spectrometry. The association between trimethyllysine and stroke outcomes was analyzed using Cox regression models. Mediation analysis was performed to examine the mediation effects of risk factors on the associations of trimethyllysine and stroke outcomes. Elevated trimethyllysine levels were associated with increased risk of cardiovascular death (quartile 4 versus quartile 1: adjusted hazard ratio [HR], 1.72; 95% CI, 1.03–2.86) and all‐cause mortality (quartile 4 versus quartile 1: HR, 1.97; 95% CI, 1.40–2.78) in multivariate Cox regression model. However, no associations were found between trimethyllysine and nonfatal stroke recurrence or nonfatal myocardial infarction. Trimethyllysine was associated with cardiovascular death independent of trimethylamine N‐oxide. Both estimated glomerular filtration rate and hs‐CRP (high‐sensitivity C‐reactive protein) had significant mediation effects on the association of trimethyllysine with cardiovascular death, with a mediation effect of 37.8% and 13.4%, respectively. Conclusions Elevated trimethyllysine level is associated with cardiovascular death among patients with ischemic stroke/transient ischemic attack. Mediation analyses propose that trimethyllysine contributes to cardiovascular death through inflammation and renal function, suggesting a possible pathomechanistic link.

Abstract Background: C-reactive protein (CRP), an acute-phase protein, is a sensitive systemic marker of inflammation and acute-phase reactions. Testing CRP concentrations at hospital admission may provide information about disease risk and overall survival. Methods: All first-ever transmittals to the department of medical and chemical laboratory diagnostics for determination of low-sensitivity CRP (n = 274 515, 44.5% male, median age 51 years) between January 1991 and July 2003 were included [median follow-up time: 4.4 years (interquartile range, 2.3–7.4 years)]. The primary endpoint was all-cause mortality. Multivariate Cox regression adjusted for sex and age was applied for analysis. Results: Compared to individuals within the reference category (CRP &lt;5 mg/L), hazard ratios (HR) for all-cause mortality increased from 1.4 (5–10 mg/L category) to 3.3 in the highest category (&gt;80 mg/L, all P &lt;0.001). CRP was associated with various causes of death. The relation of CRP to cancer death was stronger than to vascular death. Younger patients with increased CRP had relatively far worse outcome than older patients (maximal HR: ≤30 years: 6.7 vs &gt;60 years: 1.7–3.7). Interestingly, both short- and long-term mortality were associated with increasing CRP concentrations (&gt;80 mg/L: HR 22.8 vs 1.4). Conclusion: Measurement of low-sensitivity CRP at hospital admission allowed for the identification of patients at increased risk of unfavorable outcome. Our findings indicate that close attention should be paid to hospitalized patients with high CRP not only because of very substantial short-term risk, but also long-term excess risk, the basis for which needs to be determined.

Background: In patients with atrial fibrillation (AF), the long-term prognosis of long electrocardiographic pauses in the ventricular action is not well-studied. Methods: Consecutive Holter recordings in patients with AF (n=200) between 2009-2011 were evaluated, focusing on pauses of at least 2.5 s. Outcomes of interest were all-cause mortality and pacemaker implantation. Results: Forty-three patients (21.5%) had pauses with a mean of 3.2 s and SD of 0.9 s. After a median follow-up of 99 months (ranging 89-111), 47% (20/43) of the patients with, and 45% (70/157) without pauses were deceased. Pauses of ≥ 2.5 s did not constitute a risk of increased mortality: HR = 0.75; (95% CI: 0.34 - 1.66); p = 0.48. Neither did pauses of ≥ 3.0 s: HR = 0.43; (95% CI: 0.06 - 3.20); p = 0.41. Sixteen percent of patients with pauses underwent pacemaker implantation during follow-up. Only pauses in patients referred to Holter due to syncope and/or dizzy spells were associated with an increased risk of pacemaker treatment: HR = 4.7 (95% CI: 1.4-15.9), p = 0.014, adjusted for age, sex and rate-limiting medication. Conclusion: In patients with AF, prolonged electrocardiographic pauses of ≥ 2.5 s or ≥ 3.0 s are not a marker for increased mortality in this real-life clinical study.

D Dimer

Background D‐dimer is involved in poor outcomes of stroke as a coagulation biomarker. We aimed to investigate the associations of the level and increase in D‐dimer between baseline and 90 days with all‐cause death or poor functional outcome in patients after ischemic stroke or transient ischemic attack. Methods and Results We collected data from the CNSRIII (Third China National Stroke Registry) study. The present substudy included 10 518 patients within 7 days (baseline) of ischemic stroke or transient ischemic attack and 6268 patients at 90 days. Poor functional outcome at 1 year was assessed on the basis of the modified Rankin Scale (≥3). Multivariable Cox regression or logistic regression was used to assess the association of D‐dimer levels with all‐cause death or poor functional outcome. D‐dimer levels at 90 days were lower than those at baseline (1.4 µg/mL versus 1.7 µg/mL; P <0.001). Higher baseline D‐dimer level was associated with all‐cause death (adjusted hazard ratio [HR], 1.77; 95% CI, 1.25–2.52; P =0.001) and poor functional outcome (adjusted odds ratio [OR], 1.49; 95% CI, 1.23–1.80; P <0.001) during 1‐year follow‐up. Higher D‐dimer level at 90 days was also associated with poor outcomes independently. Furthermore, an increase in D‐dimer levels between baseline and 90 days was associated with all‐cause death (since 90 days to 1 year after index event) (adjusted HR, 1.99; 95% CI, 1.12–3.53; P =0.019) but not with poor functional outcome (adjusted OR, 1.08; 95% CI, 0.82–1.41). Conclusions Our study shows that high level and an increase in D‐dimer between baseline and 90 days are associated with poor outcomes in patients after ischemic stroke or transient ischemic attack.

Background and Purpose: Following transient ischemic attack (TIA), there is increased risk for ischemic stroke. The American Heart Association recommends admission of patients with ABCD2 scores ≥3 for observation, rapid performance of diagnostic tests, and potential acute intervention. We aimed to determine if there is a relationship between ABCD2 scores, in-hospital ischemic events, and in-hospital treatments after TIA admission. Methods: We reviewed consecutive patients admitted between 2006 and 2011 following a TIA, defined as transient focal neurological symptoms attributed to a specific vascular distribution and lasting <24 h. Three interventions were prespecified: anticoagulation for atrial fibrillation, carotid or intracranial revascularization, and intravenous or intra-arterial reperfusion therapies. We compared rates of in-hospital recurrent TIA or ischemic stroke and the receipt of interventions among patients with low (<3) versus high (≥3) ABCD2 scores. Results: Of 249 patients, 11 patients (4.4%) had recurrent TIAs or strokes during their stay (8 TIAs, 3 strokes). All 11 had ABCD2 scores ≥3, and no neurological events occurred in patients with lower scores (5.1 vs. 0%; p = 0.37). Twelve patients (4.8%) underwent revascularization for large artery stenosis, 16 (6.4%) were started on anticoagulants, and no patient received intravenous or intra-arterial reperfusion therapy. The ABCD2 score was not associated with anticoagulation (p = 0.59) or revascularization (p = 0.20). Conclusions: Higher ABCD2 scores may predict early ischemic events after TIA but do not predict the need for intervention. Outpatient evaluation for those with scores <3 would potentially have delayed revascularization or anticoagulant treatment in nearly one-fifth of ‘low-risk' patients.

Abstract Background Stroke prevention via lifestyle modification is a public health priority in developed countries. Few studies have examined the association of high-risk lifestyle factors with long-term mortality of stroke survivors. Therefore, this study aims to explore the effect of key lifestyle factors on all-cause mortality after stroke. Methods Sample is derived from the 45 and Up Study, the largest ongoing study in the Southern Hemisphere focusing on the health of people aged 45 years and older living in NSW, Australia. The lifestyle data in the 45 and Up Study between 2006 to 2015 were linked with data from the NSW Registry of Births, Deaths and Marriages, NSW Cause of Death Unit Record File, and NSW Admitted Patient Data Collection by the Centre for Health Record Linkage. We defined a high-risk lifestyle as no vigorous exercise, smokers, or &gt; 10 alcoholic drinks/week. Multivariate Cox regression model is used to examine the effect of high-risk lifestyle on survival using 10-year all-cause mortality as the main outcome, adjusted for key confounders. Results We analysed information on 8410 adults with a stroke event occurring prior to the baseline 45 and Up Study, and 31% of them died in 10 years. 6219 participants were identified as having a high-risk lifestyle at baseline. Being a current smoker and without vigorous exercise were associated with 41% (95% CI: 16%, 73%) and 52% (95% CI: 30%, 78%) increase in the likelihood of death in 10 years, respectively. However, high-risk alcohol drinking was not significantly associated with survival. Of note, having cardiovascular-related comorbidities showed greater risks of mortality (HR range, 3.6-7.2). Conclusions High-risk lifestyle factors were associated with an increased risk of long-term all-cause mortality, suggesting that enhancing public health initiatives to promote 'healthy' lifestyle behaviours can be of great benefit to stroke survivors. Key messages It is essential for stroke survivors to maintain a healthy lifestyle to delay all-cause mortality. Stroke survivors with high-risk lifestyle may be associated with increased likelihood of death if they have comorbidities such as diabetes and hypertension.
