BackgroundWe investigated the association between international normalised ratio (INR) and prothrombin time (PT) levels on hospital admission and in-hospital outcomes in acute ischaemic stroke (AIS) patients.MethodsA total of 3175 AIS patients enrolled from December 2013 to May 2014 across 22 hospitals in Suzhou city were included. We divided patients into four groups according to their level of admission INR: (<0.92), Q2 (0.92–0.98), Q3 (0.98–1.04) and Q4 (≥1.04) and PT. Logistic regression models were used to estimate the effect of INR and PT on death or major disability (modified Rankin Scale score (mRS)>3), death and major disability (mRS scores 4–5) separately on discharge in AIS patients.ResultsHaving an INR level in the highest quartile (Q4) was associated with an increased risk of death or major disability (OR 1.69; 95% CI 1.23 to 2.31; P-trend=0.001), death (OR, 2.64; 95% CI 1.12 to 6.19; P-trend=0.002) and major disability on discharge (OR, 1.56; 95% CI 1.13 to 2.15; P-trend=0.008) in comparison to Q1 after adjusting for potential covariates. Moreover, in multivariable logistic regression models, having a PT level in the highest quartile also significantly increased the risk of death (OR, 2.38; 95% CI 1.06 to 5.32; P-trend=0.006) but not death or major disability (P-trend=0.240), major disability (P-trend=0.606) on discharge.ConclusionsHigh INR at admission was independently associated with death or major disability, death and major disability at hospital discharge in AIS patients and increased PT was also associated with death at hospital discharge.

Abstract Background Post-stroke delirium has a negative impact on functional outcome. We explored if there is any association between delirium, subsyndromal delirium and long-term mortality after ischaemic stroke and transient ischaemic attack. Methods We included 564 patients with ischaemic stroke or transient ischaemic attack. We assessed symptoms of delirium during the first 7 days after admission. We used Cox proportional hazards models to analyse all-cause mortality during the first 5 years after stroke. Results We diagnosed delirium in 23.4% and subsyndromal delirium in 10.3% of patients. During the follow-up, 72.7% of patients with delirium, 51.7% of patients with subsyndromal delirium and 22.7% of patients without delirious symptoms died (P < 0.001). Patients with subsyndromal delirium and delirium had higher risk of death in the multivariate analysis (HR 1.72, 95% CI 1.11–2.68, P = 0.016 and HR 3.30, 95% CI 2.29–4.76, P < 0.001, respectively). Conclusions Post-stroke delirium is associated with long-term mortality. Patients with subsyndromal delirium are at the intermediate risk of death.

With the onset of the COVID-19 pandemic, it became apparent that, in addition to pulmonary infection, extrapulmonary manifestations such as cardiac injury and acute cerebrovascular events are frequent in patients infected with SARS-CoV-2, worsening clinical outcome. We reviewed the current literature on the pathophysiology of cardiac injury and its association with acute ischaemic stroke. Several hypotheses on heart and brain axis pathology in the context of stroke related to COVID-19 were identified. Taken together, a combination of disease-related coagulopathy and systemic inflammation might cause endothelial damage and microvascular thrombosis, which in turn leads to structural myocardial damage. Cardiac complications of this damage such as tachyarrhythmia, myocardial infarction or cardiomyopathy, together with changes in hemodynamics and the coagulation system, may play a causal role in the increased stroke risk observed in COVID-19 patients. These hypotheses are supported by a growing body of evidence, but further research is necessary to fully understand the underlying pathophysiology and allow for the design of cardioprotective and neuroprotective strategies in this at risk population.

Abstract Context and Objectives: Ischaemic stroke (IS) causes disability and uses massive public health resources. Cumulative disability from recurrence may be reduced with cardiometabolic risk reduction strategies e.g., lowering blood pressure (BP). We hypothesized that intensive exercise plus best available care in adults with recent IS improves fitness, glucose metabolism, muscle protein synthesis in paretic limbs compared to controls. BP changes were compared between intervention (INT) and controls (CON). Research Design and Setting: A randomised, interventional clinical trial conducted in Jamaican adults subjects: We investigate 103 adults with recent IS and residual weakness. Forty-nine subjects (24 women: mean age 61.5; 25 men: mean age 63.8) received task-oriented exercise training (TEXT) plus best available care. Fifty-four subjects (23 women: mean age 60.2; 31 men: mean age 61.3) received best care, including exercise advice. Measurements: We measured baseline, 3-month and 6-month BP. Results: After recent IS, TEXT plus best available care reduced systolic BP by 21 mmHg and diastolic by 12 mmHg compared to controls, independent of medication adherence, body composition; stroke severity. Men in the TEXT group had increased lean mass (P < 0.007), VO2 max (P = 0.03); 6-minute walk distance (P = 0.003). Leg press on paretic (P = 0.004) and non-paretic (P < 0.001) increased with TEXT vs CON over 6 months, in both sexes (P-values for sex difference > 0.2). Time-to-chair-rise decreased in both sexes who received intervention vs controls (P <0.04) Conclusions: TEXT results in significant blood pressure reduction in adults with recent ischaemic stroke and residual weakness when compared with best available medical care only.
