Stroke-Heart syndrome: a population-based cohort study and cluster analysis

Abstract Background The onset of acute cardiovascular complications following a stroke, also known as "Stroke-Heart Syndrome", can occur in up to 20% of patients following a stroke. The syndrome remains under-investigated and limited data exists related to the occurrence and impact of the Stroke-Heart Syndrome in an Asian population. Objectives We aimed to investigate the potential impact of the Stroke-Heart Syndrome and its associations in a retrospective population based-cohort study. Methods The analysis included patients with new-onset ischaemic stroke (IS) June 2006 and May 2022 with 5 years’ follow-up. Patients who developed acute cardiovascular complications within 28 days of their index stroke were compared to patients who did not. The association between acute cardiovascular complications and longer term outcomes were evaluated using multivariate Fine-Grey analyses to adjust for competing risk of mortality, and a Cox regression model for all-cause mortality. Inverse probability of treatment weighting was applied prior to analysis. Furthermore, a hierarchical cluster analysis was performed in the cohort of stroke patients with "Stroke-Heart Syndrome", to further evaluate associations between the identified clusters and (i) longer term outcomes, as well as (ii) the development of acute cardiovascular complications. Results A total of 141,118 patients (median age 72.4 (IQR 62.6 to80.8) years; 45.4% female) were included in the analysis, 6,457 of who developed acute cardiovascular complications, and 134,661 of whom did not. At 5 years follow-up, acute cardiovascular complications were associated with a higher risk of developing recurrent ischaemic stroke (Sub-distribution Hazard Ratio [SHR]: 1.20, 95% Confidence Interval [CI]: 0. 1.12-1.28, p= <0.001), haemorrhagic stroke (SHR: 1.15, 95%CI: 1.03-1.28, p=0.014), myocardial infarction (SHR: 1.53, 95%CI: 1.39-1.69, p=<0.001), and cardiovascular death (SHR: 1.57, 95%CI: 1.45-1.71, p=<0.001) as well as all-cause mortality (HR: 1.07, 95%CI: 1.07-1.07, p=<0.001). A total of 4 clusters were identified in the cluster analysis. Compared to Cluster 3, the other Clusters were associated with increased 5-year risk of myocardial infarction, cardiovascular death and all-cause mortality (p=<0.001). In this cohort, compared to Cluster 2, the other clusters had an increased risk of developing acute cardiovascular complications, in particular acute ischaemic heart disease and acute heart failure (p=<0.001). Cluster 3 tended to be younger with fewer comorbidities and prescribed medications. Over 90% of the patients in Cluster 2 were aged over 75 (with 43% aged 85 years or over). Conclusion Stroke-Heart Syndrome was associated with long-term adverse cardiovascular events in this Asian cohort of ischaemic stroke patients.

The clinical characteristics and prognosis of patients with acute non-ST-segment elevation myocardial infarction complicated with impaired activity daily living

Abstract Background Impaired activities of daily living (ADL) have been identified as an independent risk factor for cardiovascular diseases. This study aims to describe the clinical characteristics, treatment modalities, and prognosis of acute non-ST-segment elevation myocardial infarction (NSTEMI) patients with impaired ADL. Methods The data for this study were derived from a Health and Medical Big Data Superplatform, comprising a retrospective cohort of patients admitted to and discharged from 72 secondary and tertiary hospitals from 2010 to 2023. The inclusion criteria encompassed patients with a discharge diagnosis of NSTEMI.ADL prior to NSTEMI was evaluated using the Barthel index(BI),a widely used assessment tool for evaluating ADL.The patients' BI were obtained from patients’ resident health records, and patients were categorized into two groups: ADL normal and ADL impaired group. A comparative analysis was conducted between the two groups regarding clinical characteristics, treatment regimens, and prognosis. Results The study included 28,227 NSTEMI patients with normal ADL and 1,576 NSTEMI patients with impaired ADL. Baseline data revealed that the ADL impaired group had a higher proportion of females (49.4% vs. 43.2%, p < 0.001), older age (77.0 [69.0, 83.0] vs. 71.0 [66.0, 78.0], p < 0.001), and a higher proportion of patients with KILLIP III and above (25.86% vs. 17.44%, p < 0.001). Additionally, the ADL impaired group had a greater number of pre-existing comorbidities. Regarding treatment, the proportion of patients undergoing percutaneous coronary intervention (PCI) was significantly lower in the ADL impaired group (16.5% vs. 65.3%, p < 0.001). Moreover, the ADL impaired group showed lower utilization rates of antiplatelet agents, ACEI/ARBs, beta-blockers, ARNI, statins, and nitrates, while the utilization rates of diuretics and cardiac glycosides were higher. In terms of prognosis, the ADL impaired group exhibited a higher in-hospital mortality rate (6.03% vs. 3.35%, p < 0.001). During a median follow-up period of 876 days, the ADL impaired group had significantly higher rates of all-cause mortality (61.2% vs. 35.9%, p < 0.001) and cardiovascular mortality (41.8% vs. 24.8%, p < 0.001), while the rate of revascularization (6.69% vs. 9.20%, p = 0.008) was lower. There were no significant differences in the risks of recurrent non-fatal myocardial infarction (10.7% vs. 10.8%, p = 0.935), recurrent stroke (10.90% vs. 9.48%, p = 0.08), and hemorrhagic stroke (0.82% vs. 0.74%, p = 0.806). Following adjustment for age, gender, KILLIP classification, medical history, and treatment strategies in a multivariable Cox regression analysis, impaired ADL remained an independent risk factor for increased all-cause mortality (aHR 1.167, 95%CI: 1.091-1.249, p < 0.001). Conclusions The decline in ADL is significantly associated with adverse clinical outcomes among NSTEMI patients.Baseline characteristics of patientsMedications of patients

Risk of thromboembolic and haemorrhagic events associated with anticoagulation among 11,355 patients with non-valvular atrial fibrillation and thrombocytopenia

Abstract Background Oral anticoagulation (OAC) is the mainstay for stroke prophylaxis in patients with non-valvular atrial fibrillation (NVAF). Management is challenging among patients with NVAF complicated with thrombocytopenia. Purpose We compared risk of thromboembolic and hemorrhagic events between vitamin-k antagonist (VKA) and direct oral anticoagulants (DOAC) users. Methods We retrospectively analyzed patients with thrombocytopenia and NVAF prescribed VKA (N=5,251, 46.2%) and DOAC (N=6,104, 53.8%) between January 2012 and July 2022 in 16 public hospitals in Hong Kong. Mild to moderate thrombocytopenia was defined as mean platelet count (PLT) 100-150 × 10^9/L and 50-100 × 10^9/L respectively, during the year of OAC initiation. Propensity-matched cohorts of VKA and DOAC were generated on the basis of age, sex, baseline co-morbidities (components of CHA2DS2VASC and HAS-BLED scores) and medications. Time to intracranial hemorrhage (ICH), gastrointestinal bleeding (GIB) and ischemic stroke (IS) was analyzed using competing risk regression, accounting for death as competing risk. Subgroup analysis was performed to detect heterogeneity of effect across mild and moderate thrombocytopenia. Secondary outcome included (i) comparisons between 4 DOAC agents with full dose; (ii) Full-dose DOAC vs. reduced-dose DOAC. Results Of the whole cohort (N=11,355, mean age 75.8±10.5, female 38.6%), 10.3% (n=1,174) and 89.7% (n=10,181) had moderate and mild thrombocytopenia, respectively. After propensity-score matching, VKA and DOAC (n=4,302 each cohort) users were well balanced at baseline characteristics, with a median follow-up of 4.0 (IQR: 1.6-7.3) years. Overall, utilization of DOAC was associated with reduced risk of ICH [Hazards Ratio (HR) 0.56 (95% CI 0.45-0.70)] and GIB [HR 0.60 (95% CI 0.48-0.75)], compared with VKA. No difference in risk of IS was observed [HR 1.00 (95%CI 0.83-1.20)]. Dosing reduction of DOAC made no difference in all outcomes. Subgroup analysis demonstrated the benefit in decreasing GIB might be more marked in moderate thrombocytopenia [(HR 0.24 (95%CI 0.09-0.61)], than in mild thrombocytopenia [HR 0.64 (95%CI 0.51-0.81)]. Conclusion In patients with NVAF and thrombocytopenia, DOAC has similar efficacy but better safety profile than VKA. In terms of GIB, the superiority appeared to be more pronounced in patients with more significant thrombocytopenia.

Intravenous thrombolysis or antiplatelet therapy for acute nondisabling ischemic stroke: A systematic review and network meta-analysis.

Uncertainties remain on the optimal treatment for acute minor stroke with nondisabling symptoms. The two most common therapeutic approaches are intravenous thrombolysis (IVT) and antiplatelet therapy, notably dual antiplatelet therapy (DAPT). We synthesized data from the literature to compare IVT to DAPT and identify the best treatment for this population. We systematically searched Pubmed, Web of Science and the Cochrane Library for randomized trials and observational studies comparing IVT, aspirin, and/or DAPT, started within 24 h of symptom onset in patients with minor stroke (NIHSS ⩽ 5) and nondisabling symptoms. Random-effects Bayesian network meta-analysis was conducted. The primary outcome was excellent functional outcome at 3 months (mRS 0-1). Secondary outcomes included mRS 0-2, symptomatic intracranial hemorrhage, mortality, and recurrent stroke. Four randomized trials and 2 observational studies (5897 patients for the analysis of the primary outcome) were included. Compared with IVT (alteplase), DAPT (clopidogrel + aspirin) was significantly associated with higher odds of mRS 0-1 (OR = 1.52, 95% CrI, 1.09-2.35), but aspirin alone was not (OR = 1.36, 95% CrI, 0.87-2.30). DAPT was also associated with lower odds of symptomatic intracranial hemorrhage than alteplase (OR = 0.14, 95% CrI, 0.03-0.91). There were no significant differences between treatment groups regarding the other outcomes. For each outcome, the ranking for the best treatment was DAPT, then aspirin, and then IVT. This network meta-analysis suggests that DAPT may be the optimal treatment for acute nondisabling stroke, with higher odds of excellent functional outcome compared with IVT.Registration: PROSPERO ID: CRD42024522038.

Time to Treatment and Outcomes of Hemorrhagic Stroke, Comparing Patients Entering Surgery before and after 120 Minutes Upon Arrival at the Emergency Department Pattani Hospital

Background: The duration between a patient’s hospital arrival and the point at which they enter surgery for hemorrhagic stroke affects survival, length of stay, health care costs, and outcome (Glasgow Outcome Scale). Therefore, a study to explore the effects of time on these outcomes is warranted. Objective: To compare treatment outcomes of patients with hemorrhagic stroke having entered surgery before and after 120 minutes upon arrival at the emergency department. Materials and Methods: A therapeutic and interventional study with a retrospective observational cohort design at Pattani Hospital in patients with hemorrhagic stroke who received treatment between October 2018 and April 2023. A retrospective review of medical records, which collected clinical characteristics and the time to treatment. Glasgow Outcome Scale was evaluated at 72 hours, two weeks, one month, and date of hospital discharge. Length of stay, health care costs, and survival status at date of hospital discharge were analyzed. Comparative analysis was performed by Fisher’s exact probability test and t-test, and prognostic analysis was performed by risk ratio. Results: Of all the patients in the present study, 49 and 182 received treatment before and after 120 minutes, respectively, upon arrival at the emergency department. Clinical characteristics of gender, age, underlying conditions, regular medications, and level of consciousness were not significantly different between the two groups. Patients who entered surgery within 120 minutes of arrival had more occurrences of basal ganglia hemorrhage compared with those who received surgery thereafter. Furthermore, patients who received surgery within 120 minutes had a 11.4% increased chance of survival. The number needed to treat (NNT) hemorrhagic stroke patients with a time to treatment of under 120 minutes is 9. However, there was an associated increase in complications, health care cost, and length of stay. The Glasgow Outcome Scale improvement was greater only in the two-week follow-up period. These results were similar when subarachnoid hemorrhage and anticoagulating medication used were excluded. Conclusion: Patients with hemorrhagic stroke who receive early surgical treatment have lower mortality rates. Adequate provision of personnel and facilities for delivering prompt care should be made available. Measures should be taken to reduce the complications of patients who receive surgical treatment after 120 minutes upon arrival at the emergency department.

Association of impaired fasting glucose with cardiometabolic multimorbidity: TheKailuan study.

We investigated the association between impaired fasting glucose (IFG) and cardiometabolic multimorbidity (CMM) in the Chinese population. We included 119,368 participants, free of diabetes mellitus and cardiovascular disease, who participated in the health examination (2006, 2008, 2010) of the Kailuan Study. According to World Health Organization diagnostic criteria, participants were divided into normal fasting blood glucose (FBG) (<6.1 mmol/L) and IFG (FBG 6.1-6.9 mmol/L) groups. CMM was defined as having two or more cardiometabolic diseases, including myocardial infarction, stroke and diabetes mellitus. We used Cox proportional hazards models to evaluate associations between IFG and CMM. During a median follow-up period of 13.94 years, 2,432 CMM incident events occurred. After adjusting potential confounders, the hazard ratio (HR) and 95% confidence interval (CI) for CMM in the IFG group was 2.83 (95% CI 2.58-3.10) versus the normal FBG group. The HR of IFG for diabetes mellitus was 3.43 (95% CI 3.30-3.55), which was >1.25 (95% CI 1.13-1.37) for myocardial infarction, 1.16 (95% CI 1.07-1.25) for ischemic stroke and 1.06 (95% CI 0.88-1.27) for hemorrhagic stroke. Compared with normal FBG, HRs for risk of IFG for CMM were 2.73 (95% CI 2.48-3.02) in men and 3.86 (95% CI 2.92-5.09) in women. IFG was a risk factor for CMM. The effect of IFG on diabetes mellitus was stronger than that on other cardiometabolic diseases. The effects of IFG for CMM differed by sex.

Short-term ozone exposure on stroke mortality and mitigation by greenness in rural and urban areas of Shandong Province, China

BackgroundShort-term exposure to ozone (O3) has been associated with higher stroke mortality, but it is unclear whether this association differs between urban and rural areas. The study aimed to compare the association between short-term exposure to O3 and ischaemic and haemorrhagic stroke mortality across rural and urban areas and further investigate the potential impacts of modifiers, such as greenness, on this association.MethodsA multi-county time-series analysis was carried out in 19 counties of Shandong Province from 2013 to 2019. First, we employed generalized additive models (GAMs) to assess the effects of O3 on stroke mortality in each county. We performed random-effects meta-analyses to pool estimates to counties and compare differences in rural and urban areas. Furthermore, a meta-regression model was utilized to assess the moderating effects of county-level features.ResultsShort-term O3 exposure was found to be associated with increased mortality for both stroke subtypes. For each 10-µg/m3 (lag0-3) rise in O3, ischaemic stroke mortality rose by 1.472% in rural areas and 1.279% in urban areas. For each 0.1-unit increase in the Enhanced Vegetation Index (EVI) per county, the ischaemic stroke mortality caused by a 10-µg/m3 rise in O3 decreased by 0.60% overall and 1.50% in urban areas.ConclusionsOur findings add to the evidence that short-term O3 exposure increases ischaemic and haemorrhagic stroke mortality and has adverse effects in urban and rural areas. However, improving greenness levels may contribute to mitigating the detrimental effects of O3 on ischaemic stroke mortality.

Recent trends of low-density lipoprotein cholesterol control and lipid-lowering therapy in patients with atherosclerotic cardiovascular disease in Taiwan: 2015–2020

ObjectiveThis study aimd to assess recent trends in the control of low-density lipoprotein cholesterol (LDL-C) and the utilization of lipid-lowering drugs (LLD) among patients with atherosclerotic cardiovascular disease (ASCVD) in Taiwan. MethodsPatients with ASCVD and without a history of hemorrhagic stroke were identified from the Taiwanese Secondary Prevention for patients with AtheRosCLErotic disease (T-SPARCLE) Registry. ASCVD patients were stratified into four categories: those who ever had acute coronary syndrome (ACS), those who underwent percutaneous coronary intervention or coronary artery bypass grafting (PCI/CABG) without ACS, those who ever had an ischemic stroke (IS) without ACS or PCI/CABG, and other ASCVD cases. We assessed their latest recorded LDL-C levels for the periods 2015–16, 2017–18, and 2019–20. LLD therapy patterns were presented as monotherapy, dual therapy, or combination therapy of three or more drugs, with statin use classified by intensity. ResultsWe identified 3831 ASCVD patients in 2015–16, 3531 in 2017–18, and 1231 in 2019–20. LLD utilization rose from 58.4% in 2015–16 to 73.2% in 2019–20. The proportions of patients achieving LDL-C goals in 2015–16, 2017–18, and 2019–20 were 21.5%, 25.8%, and 33.3% in the ACS cohort (goal <70 mg/dL); 20.4%, 26.1%, and 39.0% in the PCI/CABG cohort (goal <70 mg/dL); 54.4%, 58.5%, and 58.9% in the IS cohort (goal <100 mg/dL); and 60.0%, 65.5%, and 67.0% in the other ASCVD cohort (goal <100 mg/dL), respectively. Over half of the patients were prescribed moderate-intensity statins. Statin use, age, history of diabetes mellitus, and hypertension were important factors for attaining LDL-C goal in ACS patients. ConclusionDespite improvements in LDL-C management observed over recent years, significant gaps remain in guideline adherence, especially for patients with ACS or PCI/CABG in Taiwan, with over 60% not meeting LDL-C targets. Intensifying efforts to align clinical practice with guidelines are imperative.

Association between sleep behaviors and stroke in Southwest China: a prospective cohort study

BackgroundSleep can function as a potential modifiable risk factor in the control and prevention of stroke. Geography significantly influences sleep patterns. The association of sleep with stroke in population of Southwest China has not so far been investigated.MethodsA total of 55,001 residents aged from 30 to 79 years in Southwest China were included in this study, obtaining their complete information of baseline survey and follow-up in China Kadoorie Biobank (CKB). Sleep-evaluating score was constructed on the basis of short/long sleep duration, insomnia, and snoring. The multivariate Cox proportional hazards regression was used to analyze the association between sleep behaviors and stroke.ResultsDuring 11.15 years of follow-up, 3410 stroke cases (572.78 cases/100,000 person-years) were documented. There exists no association of sleep-evaluating score with the risk of stroke in the total population. Male-predisposing association between sleep-evaluating score and risk of stroke was observed (for total stroke, HR = 1.52, 95% CI: 1.03–2.23; for hemorrhagic stroke, HR = 2.31, 95% CI: 1.22–4.34), with anisotropism in male residents with overweight and obesity (HR = 1.93, 95% CI: 1.03–3.63), and those without hypertension (HR = 1.76, 95% CI: 1.01–3.07) in the baseline survey.ConclusionsThere exists the male-predisposing association between sleep-evaluating score and the risk of stroke in Southwest China. Improving sleep is required for reducing the risk of stroke.

Door-in-Door-Out Times at Referring Hospitals and Outcomes from Hemorrhagic Stroke

Interhospital transfer is often required in the care of patients with hemorrhagic stroke. Guidelines recommend a door-in-door-out (DIDO) time of ≤120 minutes at the transferring emergency department (ED); however, it is unknown whether DIDO times are related to clinical outcomes of hemorrhagic stroke. Retrospective, observational cohort study using US registry data from Get With The Guidelines-Stroke participating hospitals. Patients include those aged ≥18 years with intracerebral hemorrhage (ICH) or subarachnoid hemorrhage (SAH) who were transferred from the ED to a Get With The Guidelines participating receiving hospital from January 1, 2019, to July 31, 2022. The primary outcome was ordinal discharge modified Rankin scale (mRS) score and secondary outcomes included dichotomous discharge mRS, ability to ambulate independently at discharge, and inhospital mortality at the receiving hospital. In all, 19,708 ICH and 7,757 patients with SAH were included. For patients with ICH, an increasing DIDO time was associated with greater odds of mRS 0 to 3 versus 4 to 6 at discharge in the unadjusted analyses (DIDO 91 to 180 minutes, odds ratio [OR] 1.15 [1.04 to 1.27]; DIDO 181 to 270 minutes, OR 1.51 [1.33, 1.71]; DIDO >270 minutes, OR 1.83 [1.58, 2.11]; versus DIDO ≤90 minutes). In the adjusted analyses, no associations were observed. Similar results were seen for mRS at discharge in patients with SAH. In both patients with ICH and SAH, longer DIDO times were associated with greater odds of independent ambulation at discharge and lower odds of inhospital mortality in the unadjusted analyses. After adjustment, the effect sizes of these associations were reduced, with some of the results based on quartiles becoming statistically nonsignificant. These findings suggest that EDs currently expedite the transfer of the sickest patients; however, prospective studies and more granular data are needed to understand the impact of early treatment and timing of transfer for patients with hemorrhagic stroke.

Migraine and its Association with Stroke in Pregnancy: A National Examination.

Background: Migraine prevalence has been estimated to be as high as 25% during reproductive years. Despite this, and the known significantly lower odds of acute stroke being correctly diagnosed among women versus men, little is known about the migraine-stroke connection in this vulnerable population. Our study seeks to provide a consolidated examination of cerebrovascular and obstetric complications of migraines in pregnant women and to evaluate the role of concurrent comorbidities. Methods: We utilized the 2016-2020 Healthcare Cost and Utilization Project's National Inpatient Sample with the International Classification of Diseases, 10th Revision diagnostic codes to compare pregnant patients with migraines with those without migraines. Multivariable logistic regression was used to examine the incidence of subtypes of stroke while controlling for confounding variables. Results: Overall, 19,825,525 pregnant patients were evaluated; 219,175 (1.1%) had a concomitant diagnosis of migraine. Pregnant patients with migraines were more likely to suffer ischemic (0.1% versus 0.0%) or hemorrhagic stroke (0.3% versus 0.1%). On multivariate analysis, acute ischemic stroke was most strongly associated with migraine with aura (odds ratio [OR], 23.26; 95% confidence interval [CI], 18.46-29.31), followed by migraine without aura (OR, 8.15; 95% CI, 4.79-13.88). Conclusions: Pregnant women with migraine are at a significantly increased risk for both ischemic and hemorrhagic stroke. Pregnant women with migraines should be cautioned that they may be at an increased risk of stroke, particularly if they are experiencing an aura, and encouraged to contact their medical providers to rule out neurological complications.

Impact of cannabis abuse on the occurrence of stroke in young people: a systematic review and meta-analysis

BackgroundThe occurrence of stroke in young people has risen significantly. This can easily lead to physical disabilities, swallowing difficulties, and cognitive impairment, among other issues, having a profound impact on families and society. Risk factors for stroke in young people differ from those for traditional stroke, with cannabis abuse emerging as a significant high-risk factor. However, the extent of the impact of cannabis abuse on the occurrence of stroke and the rate of disability in young people remains unclear. To clarify this issue and provide evidence supporting the primary prevention of stroke in young people, this systematic review and meta-analysis summarizes the latest findings from previous studies.MethodsA systematic search of PubMed, EMBASE, Cochrane Library, and Web of Science databases was conducted until April 2023. The review included observational studies comparing stroke risk estimates between cannabis abusers and non-users.ResultsThis review included six observational studies focusing on cannabis abuse, involving 119,284,152 participants. A significant association was found between cannabis abuse and an increased risk of stroke [OR = 1.14, 95% CI (1.08, 1.20)]. However, there was substantial heterogeneity among the studies (I2 = 89%, p &amp;lt; 0.001). After adjusting for confounders such as smoking and alcohol abuse, we found a stronger association between cannabis abuse and stroke in young adults [OR = 1.21, 95% CI (1.12, 1.29)]. Subgroup analyses revealed no significant difference in stroke risk between ischemic and hemorrhagic strokes (p = 0.43).ConclusionThe results of our systematic review and meta-analysis showed that cannabis abuse has a more significant effect on the occurrence of stroke in young people; however, it was not possible to distinguish whether cannabis abuse is more likely to cause ischemic or hemorrhagic stroke. Further research is needed to explore the impact of different drug types, dosages, and behaviors on stroke risk.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/, Identifier CRD42023443261.

Outcomes of left atrial appendage closure versus oral anticoagulant therapy in patients with atrial fibrillation: an updated meta-analysis of randomized control trials.

The purpose of this study is to compare the clinical results of Left Atrial Appendage Closure (LAAC) and oral anticoagulation (OAC) in individuals with AF. For randomized controlled trials (RCTs) comparing the clinical results of OAC to LAAC in patients with atrial fibrillation (AF), we searched PubMed, ScienceDirect, and Cochrane. The included publications were subjected to meta-analyses using Review Manager v5.4. In comparison to OAC, LAAC was linked with a decreased incidence of all stroke (OR 0.68; 95% CI 0.55-0.84; p = 0.0004). LAAC was also linked to a decreased risk of hemorrhagic stroke (OR 0.20, 95% CI 0.07-0.55; p = 0.002). There is no statistically significant difference between the two groups in terms of ischemic stroke (OR 1.05; 95% CI 0.59-1.84; p = 0.88) or systemic embolization (OR 1.02; 95% CI 0.42-2.46; p = 0.97). According to our meta-analysis, the LAAC was less likely than the OAC to have a complete or hemorrhagic stroke. For the two groups, however, there was no difference in the risk of ischemic stroke or systemic embolization.

The effects of rehabilitation potential on activities of daily living in patients with stroke in Taiwan: a prospective longitudinal study.

This study aimed to explore the effect of three-dimensional rehabilitation potential on the activity of daily living (ADL) among patients with stroke in rehabilitation wards. Prospective longitudinal study. Two rehabilitation wards situated within a nationally recognized referral centre in Northern Taiwan, followed by subsequent discharge. A total of 101 participants were admitted due to either a primary or recurring incident of infarction or haemorrhagic stroke, subsequently being transferred to the rehabilitation ward of a medical centre. Not applicable. Rehabilitation potential included biological (swallowing ability, muscle power, and urinary incontinence), psychological (rehabilitation motivation and cognitive function), and social (social support) dimensions. The rehabilitation treatment outcome was activities of daily living measured using the Barthel Index. Time-variant variables, including swallowing ability, rehabilitation motivation, social support, and ADL, were collected at the time of transfer to the rehabilitation ward, 1-3 days before discharge, and 1 month after discharge. The results of the generalized estimating equations model revealed that poor swallowing ability, lower muscle power, and urinary incontinence in the biological dimension, along with lower rehabilitation motivation and moderate cognitive impairment in the psychological dimension, are significant indicators of rehabilitation potential among stroke patients. When the different dimensional rehabilitation potential was considered overall, both biological and psychological indicators can still predict ADL outcomes during and after inpatient rehabilitation therapy. Of these indicators, swallowing ability and rehabilitation motivation were positively correlated with ADL over time. Further, increased rehabilitation motivation enhanced the protective effect of swallowing ability on ADL. Important indicators of rehabilitation potential, which can predict ADL outcomes, were identified for stroke patients in the rehabilitation ward. Policymakers can design appropriate intervention plans to enhance the rehabilitation potential and improve the effectiveness of inpatient rehabilitation treatment for stroke patients.

Unveiling Therapeutic Challenges: A Unique Case of Intracranial Myroides odoratimimus Infection Following Hemorrhagic Stroke.

Intracranial infections post-neurosurgical procedure pose substantial morbidity and mortality risks. Myroides odoratimimus, an opportunistic gram-negative pathogen, represents a real challenge because of limited clinical experience. This article details the second reported case of intracranial M. odoratimimus infection associated with external ventricular drains in an immunocompetent adult. Treatment involved a 21-day course of intravenous antibiotherapy using meropenem and vancomycin. This case underscores the complexity of managing rare complications, providing insights into therapeutic strategies for this challenging condition.

Predictive accuracy of clinicians estimates of death and recovery after acute intracerebral hemorrhage: pre-specified analysis in INTERACT3 study.

Accurately predicting a patient's prognosis is an important component of decision-making in intracerebral hemorrhage (ICH). We aimed to determine clinicians' ability to predict survival, functional recovery, and return to premorbid activities in patients with ICH. Pre-specified secondary analysis of the third INTEnsive care bundle with blood pressure Reduction in Acute Cerebral hemorrhage Trial (INTERACT3), an international, multicenter, stepped-wedge cluster randomized controlled trial. Clinician perspectives on prognosis were collected at hospital admission and Day 7 (or before discharge). Prognosis questions were the likelihood of (i) survival at 48 hours and 6 months, (ii) favorable functional outcome (recovery walking and self-care) and (iii) return to usual activities at 6 months. Clinician predictions were compared with actual outcomes. Most clinician participants were from neurosurgery (75%) with a median of 8 working years (IQR 5-14) of experience. Of the 6305 randomized patients who survived 48 hours, 213 (3.4%) were predicted to die (positive predictive value [PPV] 0.99, 95% confidence interval [CI] 0.99-0.99). Of 5435 patients who survived 6 months, 209 (3.8%) were predicted to die (PPV 0.93, 95% CI 0.92-0.93). Predictions on favorable functional outcome (PPV 0.54, 95% CI 0.52-0.56) and satisfied ability to return to usual activities (PPV 0.50, 95% CI 0.49-0.52) were poor. Prediction accuracy varied by working years and region of practice. In patients with ICH, clinician estimates of death are very good but conversely they are poor in predicting higher levels of functional recovery and activities.

2024 Guideline for the Primary Prevention of Stroke: A Guideline From the American Heart Association/American Stroke Association.

The "2024 Guideline for the Primary Prevention of Stroke" replaces the 2014 "Guidelines for the Primary Prevention of Stroke." This updated guideline is intended to be a resource for clinicians to use to guide various prevention strategies for individuals with no history of stroke. A comprehensive search for literature published since the 2014 guideline; derived from research involving human participants published in English; and indexed in MEDLINE, PubMed, Cochrane Library, and other selected and relevant databases was conducted between May and November 2023. Other documents on related subject matter previously published by the American Heart Association were also reviewed. Ischemic and hemorrhagic strokes lead to significant disability but, most important, are preventable. The 2024 primary prevention of stroke guideline provides recommendations based on current evidence for strategies to prevent stroke throughout the life span. These recommendations align with the American Heart Association's Life's Essential 8 for optimizing cardiovascular and brain health, in addition to preventing incident stroke. We also have added sex-specific recommendations for screening and prevention of stroke, which are new compared with the 2014 guideline. Many recommendations for similar risk factor prevention were updated, new topics were reviewed, and recommendations were created when supported by sufficient-quality published data.

The Impact of the COVID-19 Pandemic on the Stroke Unit of a Portuguese Community Hospital.

It is essential to understand the consequences of the COVID-19 pandemic on stroke care, contemplating the potential health and economic consequences of missed diagnoses or treatments. This study examined the pandemic's effects on stroke epidemiology, clinical characteristics, and treatment in a hospital setting, comparing data from March 2020 to February 2021 with the homologous period the previous year. A secondary analysis focused on the state of emergency periods (March 19 to May 2 and November 6 to February 28). The sample included 730 stroke admissions, with 343 during the pandemic. There was a 24.75% reduction in the average daily occupancy rate (p<0.001) and a slight decrease in average daily admissions, especially in June from 132% to 74% (p=0.01). There was a moderate negative correlation between the number of COVID-19 cases and occupancy rates in January (r{s}=-0.422, p=0.01) and February (r{s}=-0.532, p=0.01). Admissions for ischemic stroke decreased by 7.2% (p=0.026), particularly mild events, with a 6.8% decrease in lacunar syndromes (p=0.048). Mechanical thrombectomy (MT) increased by 5.4% (p=0.046), while intravenous thrombolysis (IVT) decreased by 2.8% (p=0.048), especially in severe stroke cases (-21.4%, p=0.001). The pandemic period documented more MT procedures than IVT. Hemorrhagic stroke admissions increased by 6.7% (p=0.01). The analysis suggests a reduction in mild ischemic stroke admissions and fewer patients undergoing IVT for severe strokes during the pandemic. Broader-scale studies are necessary to confirm these findings. Considering the documented decline in diagnosis and treatment, minimizing the impact on stroke care during potential sanitary crises is paramount.

Seasonal and monthly stroke incidence in relation to weather variables: a preliminary single-centre epidemiologic study

This single-centre epidemiologic study investigated seasonal/monthly stroke incidence and stroke-related mortality in relation to weather variables, gender, age, as well as stroke subtype and stroke aetiology. The study involved 638 patients hospitalised due to stroke at the Neurology Ward with a stroke unit at the Regional Hospital in Poland, during one complete calendar year. The data collected included the date of admission to the ward, year of birth, sex, type and subtype of stroke relative to the aetiology and location within different arteries as well as mortality. The data related to wind speed, atmospheric pressure, and temperature were acquired from the archive at the weather station in Tarnów, Poland. Majority of the patients in the study group were aged 66–85 years (57.2%), and there were more women than men. Ischaemic stroke was significantly more common than haemorrhagic stroke (87 vs 13%). Large artery atherosclerosis was the predominant cause of stroke, particularly in June and October, and total anterior circulation stroke (TACS) was the most common type, particularly in January and December. The analysis showed that stroke type and aetiology, as well as weather variables such as temperature and pressure, were associated with stroke incidence and mortality rates. The findings suggest that both high and low temperatures may contribute to an increased stroke incidence, as significant differences in the number of stroke cases are observed during periods of extreme temperatures. Therefore, increased vigilance is necessary during periods of both hot and cold weather. Further research is needed to better understand these relationships and develop effective prevention strategies.

Global, Regional, and National Burden of Stroke, 1990-2021: A Systematic Analysis for Global Burden of Disease 2021.

This study aims to perform a comprehensive analysis of stroke burden from the Global Burden of Disease 2021. We conducted a comprehensive analysis of the burden, including prevalence, incidence, mortality, and disability-adjusted life year rates, for stroke across 204 countries and regions from 1990 to 2021 using data from the Global Burden of Disease 2021. We calculated the estimated annual percentage change (EAPC) and performed a joinpoint regression analysis to identify the trends. We also explored the association between the stroke burden and sociodemographic index. The age-standardized prevalence, incidence, mortality, and disability-adjusted life year rates for stroke were 1099.310, 141.553, 87.454, and 1886.196 per 100 000 persons in 2021, respectively. The general stroke burden trends declined in EAPC analysis (age-standardized prevalence: EAPC, -0.37; age-standardized incidence: EAPC, -0.99; age-standardized mortality: EAPC, -1.81; and disability-adjusted life year: EAPC, -1.76). However, we found an increasing burden of stroke in East Asia and Southern Sub-Saharan Africa (EAPC >0). The global burdens of intracerebral hemorrhage, subarachnoid hemorrhage, and ischemic stroke showed a similar trend. The stroke, intracerebral hemorrhage, and ischemic stroke burdens were heavier in men than in women, except for that of subarachnoid hemorrhage in women. Our joinpoint regression analysis revealed that the age-standardized burden rates of stroke decreased from 1990 to 2021 (average annual percent change <0), whereas an upward trend was observed between 2019 and 2021 (average annual percent change >0). The burden of stroke was inversely proportional to the sociodemographic index (P<0.05), except in the case of subarachnoid hemorrhage. The actual stroke burden showed an increasing trend for stroke, intracerebral hemorrhage, subarachnoid hemorrhage, and ischemic stroke in 2021 (during the coronavirus pandemic). We found age-standardized rates of stroke burden declining over time, but some areas exhibited a notable increase in the prevalence, incidence, mortality, and disability-adjusted life year rates.
