This study aimed to evaluate the prognostic value of acute phase blood pressure in patients with acute ischemic stroke by determining whether or not it contributes to clinical outcome. We studied 515 consecutive patients admitted within the first 48 hours after the onset of ischemic strokes, employing systolic and diastolic blood pressure measurements recorded within 36 hours after admission. High blood pressure was defined when the mean of at least 2 blood pressure measurements was ≥200 mmHg systolic and/or ≥110 mmHg diastolic at 6 to 24 hours after admission or ≥180 mmHg systolic and/or ≥105 mmHg diastolic at 24 to 36 hours after admission. The high blood pressure group was found to include 16% of the patients. Age, sex, diabetes mellitus, hypercholesterolemia, atrial fibrillation, ischemic heart disease, stroke history, carotid artery stenosis, leukoaraiosis, NIH Stroke Scale (NIHSS) on admission and mortality were not significantly correlated with either the high blood pressure or non-high blood pressure group. High blood pressure on admission was significantly associated with a past history of hypertension, kidney disease, the modified Rankin Scale (mRS) on discharge and the length of stay. On logistic regression analysis, with no previous history of hypertension, diabetes mellitus, atrial fibrillation, and kidney disease were independent risk factors associated with the presence of high blood pressure [odds ratio (OR), 1.85 (95% confidence interval (CI): 1.06-3.22), 1.89 (95% CI: 1.11-3.22), and 3.31 (95% CI: 1.36-8.04), respectively]. Multi-organ injury may be presented in acute stroke patients with high blood pressure. Patients with high blood pressure had a poor functional outcome after acute ischemic stroke.

Background: Thrombolytic therapy for acute ischemic stroke with IV alteplase is increasingly well established in North America but not elsewhere. Baseline factors that altered the response to alteplase were not identified by the National Institute of Neurological Disorders and Stroke tPA Stroke Study Group.Methods: The authors gathered information from centers in the United States, Canada, and Germany on 1,205 patients with acute ischemic stroke treated with IV alteplase. The purpose was to identify independent factors that were predictive of good outcome using multivariable logistic regression modelling. The modified Rankin Scale score was dichotomized into good outcome (mRS 0 to 1) and poor outcome (mRS >1) as the primary outcome measure.Results: In relative order of decreasing magnitude, milder baseline stroke severity, no history of diabetes mellitus, normal CT scan, normal pretreatment blood glucose level, and normal pretreatment blood pressure were independent predictors of good outcome among patients treated with IV alteplase for acute ischemic stroke. Confounding was observed among history of diabetes mellitus, CT scan appearance, baseline serum glucose level, and blood pressure, suggesting important relationships among these variables.Conclusions: Several factors were independently predictive of good outcome among patients with acute ischemic stroke treated with alteplase. These results require further confirmation before clinical implementation.

Introduction : Previous research into the administration of rTPA therapy in acute ischemic stroke patients has largely focused on the general population, however the comorbid clinical factors held by stroke patients are important factors in clinical decision making. One such comorbid condition is Atrial Fibrillation. The purpose of this study is to determine the clinical factors associated with the administration of rtPA in Acute Ischemic Stroke (AIS) patients specifically with a past medical history of Atrial Fibrillation (AFib). Methods : The data for this analysis was collected at a regional stroke center from January 2010 to June 2016 in Greenville, SC. It was then analyzed retrospectively using a multivariate logistic regression to identify factors significantly associated with the inclusion or exclusion receiving rtPA therapy in the AIS/AFib patient population. This inclusion or exclusion is presented as an Odds Ratio and all data was analyzed using IBM SPSS. Results : A total of 158 patients with Atrial Fibrillation who had Acute Ischemic Strokes were identified. For the 158 patients, the clinical factors associated with receiving rtPA therapy were a Previous TIA event (OR = 12.155, 95% CI, 1.125‐131.294, P < 0.040), the administration of Antihypertensive medication before admission (OR = 7.157, 95% CI, 1.071‐47.837, P < 0.042), the administration of Diabetic medication before admission (OR = 13.058, 95% CI, 2.004‐85.105, P < 0.007), and serum LDL level (OR = 1.023, 95% CI, 1.004‐1.042, P < 0.16). Factors associated with not receiving rtPA therapy included a past medical history of Depression (OR = 0.012, 95% CI, 0.000‐0.401, P < 0.013) or Obesity (OR = 0.131, 95% CI, 0.034‐0.507, P < 0.003), Direct Admission to the Neurology Floor (OR = 0.179, 95% CI, 0.050‐0.639, P < 0.008), serum Lipid level (OR = 0.544, 95% CI, 0.381‐0.984, P < 0.044), and Diastolic Blood Pressure (OR = 0.896, 95% CI, 0.848‐0.946, P < 0.001). Conclusions : The results of this study demonstrate that there are significant associations between several clinical risk factors, patient lab values, and hospital admission factors in the administration of rTPA therapy to AIS patients with a past medical history of Atrial Fibrillation. Further research is recommended to determine the extent and reasoning behind of these associations as well as their impact on the clinical course for AIS/AFib patients.

IntroductionAtrial fibrillation (AF) is the most common heart arrhythmia. The condition is known to increase the risk of ischemic stroke (IS). Classical risk factors for the development of AF include advanced age, hypertension, diabetes mellitus, coronary heart disease and lipid metabolism disorders. Importantly, these are also recognized risk factors for ischemic stroke. Therefore, the purpose of this study was to investigate AF risk factors in patients with IS.Material and methodsThis is single-centre retrospective study which included 696 patients with acute ischemic stroke and nonvalvular atrial fibrillation and 1678 patients with acute ischemic stroke without atrial fibrillation.ResultsIn this study we found – based on a univariable and multivariable logistic regression model – that compared to the patients with IS without AF, the group of patients which suffered from IS with nonvalvular atrial fibrillation (NVAF) had a higher proportion of patients who smoked cigarettes (OR = 15.742, p < 0.01; OR = 41.1, p < 0.01), had hypertension (OR = 5.161, p < 0.01; OR = 5.666, p < 0.01), history of previous stroke (OR = 3.951, p < 0.01; OR = 4.792, p < 0.01), dyslipidemia (OR = 2.312, p < 0.01; OR = 1.592, p < 0.01), coronary heart disease (OR = 2.306, p < 0.01; OR = 1.988, p < 0.01), a greater proportion of female patients (OR = 1.717, p < 0.01; OR = 2.095, p < 0.01), higher incidence of diabetes mellitus (OR = 1.341, p < 0.01; OR = 1.261, p = 0.106) and more patients in old age (OR = 1.084, p < 0.01; OR = 1.101, p < 0.01).ConclusionsOur study demonstrates a need for thorough and systematic monitoring of post-ischemic stroke patients in whom AF has not been detected and who display other important risk factors. Regardless of the stroke, these factors may be responsible for development of AF.

Background and Purpose: Endovascular techniques are frequently employed to treat large artery occlusion in acute ischemic stroke (AIS). We sought to determine the predictors and clinical impact of intracranial hemorrhage (ICH) after endovascular therapy. Methods: Retrospective analysis of consecutive patients presenting to 13 high-volume stroke centers with AIS due to proximal occlusion in the anterior circulation who underwent endovascular treatment within 8 hours from symptom onset. Logistic regression was performed to determine the variables associated with ICH, hemorrhagic infarction (HI), and parenchymal hematomas (PH) as well as 90-day poor outcome (mRS≥3), and mortality. Results: A total of 1122 patients (mean age, 67±15 years; median NIHSS, 17 [IQR13-20]) were studied. Independent predictors for HI included diabetes mellitus (OR 2.27, 95%CI [1.58-3.26], p<0.0001), pre-procedure IV tPA (1.43[1.03-2.08], p<0.037), Merci thrombectomy (1.47[1.02-2.12], p<0.032), and longer time to puncture (1.001[1.00-1.002], p<0.026). Patients with atrial fibrillation (1.61[1.01-2.55], p<0.045) had a higher risk of parenchymal hematomas (PH) while the use of intra-arterial tPA (0.57[0.35-0.90], p<0.008) was associated with lower chances of PH. Both the presence of HI (2.23[1.53-3.25], p< 0.0001) and PH (6.24[3.06-12.75], p< 0.0001) were associated with poor functional outcomes; however, only PH was associated with higher mortality (3.53[2.19-5.68], p<0.0001). Conclusions: In AIS patients undergoing endovascular therapy, diabetes mellitus, longer time to treatment, and Merci thrombectomy appear to be associated with a higher risk for HI while atrial fibrillation appears to result in a higher risk for PH. While both HI and PH are associated with poor outcomes only PH is associated with higher mortality.

BackgroundThere is sparse literature on the natural history of blood pressure (BP) after intra-arterial therapy (IAT) for acute ischemic stroke (AIS).MethodsA retrospective analysis was performed of patients with AIS who underwent IAT without endotracheal intubation for internal carotid artery terminus (ICA-T) or M1 middle cerebral artery occlusion from January 2008 to February 2012. Systolic BP (SBP) values at the beginning (First) and end (End) of IAT and for 36 h after the procedure were collected. Successful recanalization was defined as Thrombolysis In Cerebral Infarction (TICI) 2b–3.ResultsSixty-two patients (14 (22.5%) ICA-T, 46 (74.2%) M1, 2 (3.2%) ICA-T+M1) met the study criteria and 37 (59.7%) achieved successful recanalization. The First and End SBP values were similar in the successful (Group R) and unsuccessful (Group NR) recanalization groups. Taking the whole cohort, End SBP was significantly lower than First SBP, but this decline was significant only in Group R. Subsequently, absolute SBP values in Group R were not significantly different from Group NR. However, when comparing the hourly decline of SBP with First SBP, Group R demonstrated a greater fall than Group NR and the decline was significantly different from hours 8 to 12 post-procedure. The SBP in Group NR then decreased further, and its difference from baseline was similar to Group R from hour 14 onwards. Mean SBP and SBP variability over 36 h were similar between the two groups.ConclusionsSBP falls significantly in patients with AIS with large vessel occlusion who recanalize with IAT. While SBP in non-recanalized patients also drops from baseline, it occurs to a lesser degree and stays higher only for a short period of time before falling to similar levels as in recanalized patients.

Abstract Background and objective The effect of atrial fibrillation (AF) on outcomes of endovascular treatment (EVT) for acute ischemic stroke (AIS) is controversial. This study aimed to investigate the association of AF with outcomes after EVT in AIS patients. Methods Subjects were selected from ANGEL-ACT registry (Endovascular Treatment Key Technique and Emergency Work Flow Improvement of Acute Ischemic Stroke) - a prospective consecutive cohort of AIS patients undergoing EVT at 111 hospitals in China between November 2017 and March 2019, and then grouped according to having a history of AF or not. After 1:1 propensity score matching, the outcome measures including the 90-day modified Rankin Scale (mRS) score, successful recanalization after final attempt, symptomatic intracranial hemorrhage (ICH) within 24 h, and death within 90 days were compared. Results A total of 1755 patients, 550 with AF and 1205 without AF, were included. Among 407 pairs of patients identified after matching, no significant differences were found in the mRS score (median: 3 vs. 3 points; P = 0.29), successful recanalization (87.2 vs. 85.3%; P = 0.42), symptomatic ICH (9. 4 vs. 9.1%; P = 0.86) and death (16.3 vs. 18.4%; P = 0.44) between patients with and without AF. Conclusion The findings of this matched-control study show comparable outcomes of EVT in Chinese AIS patients with and without AF, which do not support withholding EVT in patients with both AIS and AF.
