Background: Low magnesium levels are associated with an elevated risk of stroke. In this study, we investigated the association between magnesium levels on hospital admission and in-hospital mortality in acute ischemic stroke (AIS) patients. Methods: A total of 2,485 AIS patients, enrolled from December 2013 to May 2014 across 22 hospitals in Suzhou city, were included in this study. The patients were divided into 4 groups according to their level of admission magnesium: Q1 (<0.82 mmol/L), Q2 (0.82-0.89 mmol/L), Q3 (0.89-0.98 mmol/L), and Q4 (≥0.98 mmol/L). Cox proportional hazard model was used to estimate the effect of magnesium on all-cause in-hospital mortality in AIS patients. Results: During hospitalization, 92 patients (3.7%) died from all causes. The lowest serum magnesium level (Q1) was associated with a 2.66-fold increase in the risk of in-hospital mortality in comparison to Q4 (hazard ratio [HR] 2.66; 95% CI 1.55-4.56; p-trend < 0.001). After adjusting for age, sex, time from onset to hospital admission, baseline National Institutes of Health Stroke Scale score, and other potential covariates, HR for Q1 was 2.03 (95% CI 1.11-3.70; p-trend = 0.014). Sensitivity and subgroup analyses further confirmed a significant association between lower magnesium levels and a high risk of in-hospital mortality. Conclusions: Decreased serum magnesium levels at admission were independently associated with in-hospital mortality in AIS patients.

Background : We investigated the association between elevated total homocysteine (tHcy) levels upon hospital admission and short-term in-hospital outcomes including pneumonia in acute ischemic stroke (AIS) patients. Methods: A total of 2,084 AIS patients enrolled from December 2013 to May 2014 across 22 hospitals in Suzhou city were included in the present study. We divided patients into four groups according to their level of admission tHcy: quartile (Q1) (<9.70 umol/L), Q2 (9.70-12.3 umol/L), Q3 (12.3-16.9 umol/L), and Q4 (≥16.9 umol/L). Logistic regression models were used to estimate the effect of tHcy on the short-term outcomes, including in-hospital pneumonia, all-cause in-hospital mortality and poor outcome upon discharge (modified Rankin Scale score ≥3) in AIS patients. Results: The risk of in-hospital pneumonia was significantly higher in patients with highest tHcy level (Q4) compared to those with lowest tHcy level (Q1) (adjusted odds ratio [OR] 1.55; 95% confidence interval [CI], 1.03-2.33; P-trend =0.019). The highest tHcy level (Q4) was associated with a 3.35-fold and 1.50-fold increase in the risk of in-hospital mortality (OR 3.35; 95% CI, 1.11–10.13; P-trend =0.015) and poor outcome upon discharge (OR 1.50; 95% CI, 1.06–2.12; P-trend =0.044) in comparison to Q1 after adjustment for potential covariates including pneumonia. Conclusion: Having a high admission tHcy level was independently associated with in-hospital pneumonia, in-hospital mortality and poor outcome upon discharge in AIS patients.

Abstract Background The impact of elevated total homocysteine (tHcy) on functional outcomes and pneumonia after acute ischemic stroke (AIS) is still not well understood. We investigated the association between tHcy levels upon hospital admission and in-hospital short-term outcomes in AIS patients. Methods A total of 2,084 AIS patients enrolled from December 2013 to May 2014 across 22 hospitals in Suzhou city were included in the present study. We divided patients into 4 groups according to their level of admission tHcy: Q1 (<9.70 umol/L), Q2 (9.70-12.3 umol/L), Q3 (12.3-16.9 umol/L), and Q4 (≥16.9 umol/L). Logistic regression models were used to estimate the effect of tHcy on the short-term outcomes, including in-hospital pneumonia, all cause in-hospital mortality and poor outcome upon discharge (modified Rankin Scale score ≥3) in AIS patients. Results During hospitalization, 332 patients (15.9%) had pneumonia, 57 patients (2.7%) died from all causes and 784 (37.6%) patients experienced poor outcome at discharge. The risk of in-hospital pneumonia was significantly higher in patients with highest tHcy level (Q4) compared to those with lowest (Q1) (adjusted odds ratio [OR] 1.55; 95% confidence interval [CI], 1.03-2.33; P -trend =0.019). The highest tHcy level (Q4) was associated with a 3.35-fold and 1.50-fold increase in the risk of in-hospital mortality(adjusted OR 3.35; 95% CI, 1.11–10.13; P -trend =0.015) and poor outcome upon discharge(adjusted OR 1.50; 95% CI, 1.06–2.12; P -trend =0.044) in comparison to Q1 after adjustment for potential covariates including pneumonia. Subgroup analyses further confirmed a significant association between higher tHcy levels and a high risk of short-term outcomes. Conclusions Having a high admission tHcy level was independently associated with in-hospital pneumonia, all cause in-hospital mortality and poor outcome upon discharge in AIS patients. Moreover, the association between higher tHcy and poor functional outcome was not modified by pneumonia.

Abstract Background: High white blood cell (WBC) count was the risk factors for mortality and pneumonia after acute ischemic stroke (AIS). Low platelet count increased the risk of mortality. We investigated the combined effect of WBC count and platelet count on hospital admission and in-hospital mortality and pneumonia in acute AIS patients.Methods: A total of 3,265 AIS patients enrolled from December 2013 to May 2014 across 22 hospitals in Suzhou city were included in the present study. We divided patients into four groups according to their level of WBC count and platelet count: LWHP (low WBC and high platelet), LWLP (low WBC and low platelet), HWHP (high WBC and high platelet) and HWLP (high WBC and low platelet). Cox proportional logistic regression model were used to estimate the combined effect of WBC count and platelet count on all cause in-hospital mortality and pneumonia in AIS patients. Results: HWLP was associated with a 2.07-fold increase in the risk of in-hospital mortality in comparison to LWHP (adjusted odds ratio [OR] 2.07; 95% confidence interval [CI], 1.02-4.18; P-trend =0.020). The risk of pneumonia was significantly higher in patients with HWLP compared to those with LWHP (adjusted OR 2.29; 95% CI, 1.57-3.35; P-trend <0.001). The C-statistic for the combined WBC count and platelet count was higher than WBC count or platelet count alone for prediction of in-hospital mortality and pneumonia (all p < 0.01). Conclusions: High WBC count combined with low platelet count level at admission was independently associated with in-hospital mortality and pneumonia in AIS patients. Moreover, the combination of WBC count and platelet count level appeared to be a better predictor than WBC count or platelet count alone.

Background: Peripheral arterial disease (PAD) is frequently present in patients with acute ischemic stroke. However, there are limited data regarding the association between ankle brachial index (ABI) ≤ 0.90 (which is diagnostic of PAD) or > 1.40 (suggesting calcified arteries) and the severity of stroke and in-hospital outcome in this population. We aimed to evaluate these associations in patients with acute ischemic stroke. Patients and methods: We prospectively studied 342 consecutive patients admitted for acute ischemic stroke (37.4 % males, mean age 78.8 ± 6.4 years). The severity of stroke was assessed with the National Institutes of Health Stroke Scale (NIHSS)and the modified Rankin scale (mRS) at admission. The outcome was assessed with the mRS and dependency (mRS 2 - 5) at discharge and in-hospital mortality. Results: An ABI ≤ 0.90 was present in 24.6 % of the patients whereas 68.1 % had ABI 0.91 - 1.40 and 7.3 % had ABI > 1.40. At admission, the NIHSS score did not differ between the 3 groups (10.4 ± 10.6, 8.3 ± 9.3 and 9.3 ± 9.4, respectively). The mRS score was also comparable in the 3 groups (3.6 ± 1.7, 3.1 ± 1.8 and 3.5 ± 2.3, respectively). At discharge, the mRS score did not differ between the 3 groups (2.9 ± 2.2, 2.3 ± 2.1 and 2.7 ± 2.5, respectively) and dependency rates were also comparable (59.5, 47.6 and 53.3 %, respectively). In-hospital mortality was almost two-times higher in patients with ABI ≤ 0.90 than in patients with ABI 0.91 - 1.40 or > 1.40 but this difference was not significant (10.9, 6.6 and 6.3 %, respectively). Conclusions: An ABI ≤ 0.90 or > 1.40 does not appear to be associated with more severe stroke or worse in-hospital outcome in patients with acute ischemic stroke.

Abstract Acute ischemic stroke (AIS) has a high risk of recurrence, particularly in the early stage. The purpose of this study was to assess the frequency and risk factors of in-hospital recurrence in patients with AIS in China. A retrospective analysis was performed of all of the patients with new-onset AIS who were hospitalized in the past three years. Recurrence was defined as a new stroke event, with an interval between the primary and recurrent events greater than 24 hours; other potential causes of neurological deterioration were excluded. The risk factors for recurrence were analyzed using univariate and logistic regression analyses. A total of 1,021 patients were included in this study with a median length of stay of 14 days (interquartile range,11–18). In-hospital recurrence occurred in 58 cases (5.68%), primarily during the first five days of hospitalization. In-hospital recurrence significantly prolonged the hospital stay (P < 0.001), and the in-hospital mortality was also significantly increased (P = 0.006). The independent risk factors for in-hospital recurrence included large artery atherosclerosis, urinary or respiratory infection and abnormal blood glucose, whereas recurrence was less likely to occur in the patients with aphasia. Our study showed that the patients with AIS had a high rate of in-hospital recurrence, and the recurrence mainly occurred in the first five days of the hospital stay. In-hospital recurrence resulted in a prolonged hospital stay and a higher in-hospital mortality rate.

Introduction: The COVID-19 pandemic has wreaked havoc on the presentation, care and outcomes of patients with acute cerebrovascular and cardiovascular conditions. We sought to measure the national impact of COVID-19 on the care for acute ischemic stroke (AIS) and acute myocardial infarction (AMI). Methods: In this retrospective, observational study, we used the Premier Healthcare Database to evaluate the changes in the volume of care and hospital outcomes for AIS and AMI in relation to the pandemic. The pandemic months were defined from March 1, 2020- April 30, 2020 and compared to the same period in the year prior. Outcome measures were volumes of hospitalization and reperfusion treatment for AIS and AMI (including intravenous thrombolysis [IVT] and/or mechanical thrombectomy [MT] for AIS and percutaneous coronary interventions [PCI] for AMI) as well as in-hospital mortality, hospital length of stay (LOS) and hospitalization costs were compared across a 2-month period at the height of the pandemic versus the corresponding period in the prior year. Results: There were 95,453 AIS patients across 145 hospitals and 19,744 AMI patients across 126 hospitals. There was a significant nation-wide decline in the absolute number of hospitalizations for AIS (-38.94%;95%CI,-34.75% to -40.71%) and AMI (-38.90%;95%CI,-37.03% to -40.81%) as well as IVT (-30.32%;95%CI,-27.02% to -33.83%), MT (-23.54%;95%CI,-19.84% to -27.70%), and PCI (-35.05%;95%CI,-33.04% to -37.12%) during the first two months of the pandemic. This occurred across low-, mid-, and high-volume centers and in all geographic regions. Higher in-hospital mortality was observed in AIS patients (5.7% vs.4.2%, p=0.0037;OR 1.41,95%CI 1.1-1.8) but not AMI patients. A shift towards an increase in the proportion of admitted AIS and AMI patients receiving reperfusion therapies suggests a greater clinical severity among patients that were hospitalized for these conditions during the pandemic. A shorter length of stay (AIS: -17%, AMI: -20%), and decreased hospitalization costs (AIS: -12%, AMI: -19%) were observed. Conclusions: Our findings shed light on the combined health outcomes and economic impact the COVID-19 pandemic has had on acute stroke and cardiac emergency care.

Background: Severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) has been associated with a significant risk of thrombotic events in critically ill patients. Aims: To summarize the findings of a multinational observational cohort of patients with SARS-CoV-2 and cerebrovascular disease. Methods: Retrospective observational cohort of consecutive adults evaluated in the emergency department and/or admitted with coronavirus disease 2019 (COVID-19) across 31 hospitals in 4 countries (2/1/2020 - 06/16/2020). The primary outcome was the incidence rate of cerebrovascular events, inclusive of acute ischemic stroke, intracranial hemorrhages (ICH), and cortical vein and/or sinus thrombosis (CVST). Results: Of the 14,483 patients with laboratory-confirmed SARS-CoV-2, 172 were diagnosed with an acute cerebrovascular event (1.13% of cohort; 1130/100,000 patients, 95%CI 970-1320/100,000), 68/171 (40.5%) of whom were female and 96/172 (55.8%) were between the ages 60-79 years. Of these, 156 had acute ischemic stroke (1.08%; 1080/100,000 95%CI 920-1260/100,000), 28 ICH (0.19%; 190/100,000 95%CI 130 - 280/100,000) and 3 with CVST (0.02%; 20/100,000, 95%CI 4-60/100,000). The in-hospital mortality rate for SARS-CoV-2-associated stroke was 38.1% and for ICH 58.3%. After adjusting for clustering by site and age, baseline stroke severity, and all predictors of in-hospital mortality found in univariate regression (p<0.1: male sex, tobacco use, arrival by emergency medical services, lower platelet and lymphocyte counts, and intracranial occlusion), cryptogenic stroke mechanism (aOR 5.01, 95%CI 1.63-15.44, p<0.01), older age (aOR 1.78, 95%CI 1.07-2.94, p=0.03), and lower lymphocyte count on admission (aOR 0.58, 95%CI 0.34-0.98 p=0.04) were the only independent predictors of mortality among patients with stroke and COVID-19. Conclusions: COVID-19 is associated with a small but significant risk of clinically relevant cerebrovascular events, particularly ischemic stroke. The mortality rate is high for COVID-19 associated cerebrovascular complications, therefore aggressive monitoring and early intervention should be pursued to mitigate poor outcomes.
