    Abstract: Introduction: External recorders allow for low-cost, non-invasive 1 to 4 weeks monitoring. However, the first 3 months of monitoring duration are the most effective to detect atrial fibrillation (AF). We show the results of the Thunder registry of patients monitored to detect AF during 90 days from the stroke. Methods: A prospective observational study was conducted with consecutive inclusion of patients with cryptogenic stroke after work up (neuroimaging, echocardiography and 24-hour cardiac monitoring) in 5 Comprenhensive Stroke Centers. Patients were continuously monitored for 90 days with a wearable Holter (Nuubo®) after the first 24 hours of the stroke onset. We analyzed the percentage of AF detection in each period (percentage of AF among those monitored), the quality of the monitoring (monitoring time), the percentage of AF by intention to monitor (detection of AF among patient included). Demographic, clinical and echocardiographic predictors of AF detection beyond one week of cardiac monitoring were assessed. Results: A total of 254 patients were included. The cumulative incidence of AF detection at 90 days was 34.84%. The monitoring time was similar among the 3 months (30 days: 544.9 hours Vs 60 days: 505.9 hours Vs 90 days: 591.25 hours) (p=0.512). The number of patients who abandoned monitoring was 7% (18/254). The cumulative percentage of intention to detect AF was 30.88% (Figure). Patients who completed monitoring beyond 30 days had higher score on the NIHSS basal scale (NIHSS 9 IQR 2-17) VS (NIHSS 3 IQR 1-9) (p=0.024). Patients with left atrial volume greater than 28.5ml/m2 had higher risk of cumulative incidence of AF according to the Kaplan Meyer curve beyond the first week of monitoring OR 2.72 (Log-rank (Mantel-Cox test) (p 〈 0.001). Conclusions: In conclusion, intensive 90-day- Holter monitoring with textile Holter was feasible and detected high percentage of AF. Enlarged left atrial volume predicted AF beyond the first week of monitoring.

    Abstract: Background and Purpose— We sought to evaluate the effects of administration of microbubbles (MBs) on the beginning, speed, and degree of middle cerebral artery (MCA) recanalization during systemic thrombolysis and continuous 2-MHz pulsed-wave transcranial Doppler (TCD) monitoring. Methods— We evaluated 111 patients with acute stroke attributable to MCA occlusion treated with intravenous tissue plasminogen activator (tPA). Thirty-eight patients were treated with tPA plus continuous 2-hour TCD monitoring plus 3 doses of 2.5 g (400 mg/mL) of galactose-based MBs given at 2, 20, and 40 minutes after tPA bolus (MB group). These patients were compared with 73 patients who were allocated to receive tPA plus continuous 2-hour TCD ultrasound (US) monitoring (tPA/US group) or tPA plus placebo monitoring (tPA group), most of whom were enrolled in a previous study of US-enhanced thrombolysis. The beginning, degree, and time to maximum completeness of recanalization during the first 2 hours of tPA bolus were recorded. Results— Median prebolus National Institutes of Health Stroke Scale (NIHSS) score was 18. Eighty patients (72%) had a proximal and 31 (28%) a distal MCA occlusion on TCD. Thirty-seven patients (33%) received tPA/US, 38 (34%) received tPA/US/MB, and 36 (32%) were treated with tPA alone. Stroke severity, time to treatment, location of MCA occlusion, and presence of carotid artery disease were similar among groups. Two-hour recanalization was seen in 14 (39%), 25 (68%), and 27 patients (71%) in the tPA, tPA/US, and tPA/US/MB groups, respectively ( P =0.004). Two-hour complete recanalization rate was significantly ( P =0.038) higher in the tPA/US/MB group (54.5%) compared with tPA/US (40.8%) and tPA (23.9%) groups. The time to beginning of recanalization after tPA bolus was 26±18 minutes in the tPA/US group and 19±12 minutes in the tPA/US/MB group ( P =0.12). Four patients (3.6%) experienced symptomatic intracranial hemorrhage: 2 (5.5%), 1 (2.7%), and 1 patient (2.6%) who received tPA only, tPA/US, and tPA/US/MB, respectively, experienced symptomatic intracranial hemorrhage. At 24 hours, 31%, 41%, and 55% of tPA, tPA/US, and tPA/US/MB improved 〉 4 points in the NIHSS score. Conclusions— Administration of MBs induces further acceleration of US-enhanced thrombolysis in acute stroke, leading to a more complete recanalization and to a trend toward better short- and long-term outcome.

    Abstract: Background and Purpose— We evaluated the impact of admission hyperglycemia (HG) on stroke outcome in relation to the timing of reperfusion in patients treated with tissue plasminogen activator (tPA). Methods— We studied 138 consecutive stroke patients with a documented middle cerebral artery (MCA) occlusion treated with intravenous tPA 〈 3 hours of stroke onset. Serum glucose was determined at baseline before tPA administration. HG was defined as a glucose level 〉 140 mg/dL. National Institutes of Health Stroke Scale (NIHSS) scores were obtained at baseline and 24 hour. Transcranial Doppler monitoring of recanalization was conducted during the first 12 hour of stroke onset. mRS was used to assess outcome at 3 months. Results— Median baseline NIHSS score was 17 points. At baseline, 42 (37.3%) patients were hyperglycemic and 96 (62.7%) normoglycemic. Reperfusion was achieved 〈 3 hours of stroke onset in 32 (23%) patients, between 3 to 6 hours in 49 (36%), 6 to 12 hours in 15 (12%), and in 32 (23%) the MCA remained occluded at 12 hours. A logistic regression model revealed that baseline NIHSS score 〉 16 points (odds ratio [OR], 3.32; 95% CI, 2.18 to 24.7; P =0.032) and admission glucose level 〉 140 mg/dL (OR, 5.65; 95% CI, 1.97 to 16.18; P =0.002) independently predicted poor outcome (modified Rankin scale, 3 to 6) at 3 months. After adjusting by age, stroke severity, site of MCA occlusion, and degree of recanalization, the contribution of HG for poor outcome was higher as shorter the time to reperfusion. The highest odds for poor outcome related to HG corresponded to patients who recanalized 〈 3 hour (OR, 3.1; 95% CI, 1.8 to 14.3; P =0.002), as compared with those who recanalized between 3 and 6 hours (OR, 2.1; 95% CI, 1.1 to 16; P =0.034) and between 6 to 12 hours (OR, 1.1; 95% CI, 0.7 to 21; P =0.43). Moreover, baseline glucose level was negatively correlated ( r =−0.45; P =0.001) with the degree of improvement in the NIHSS score at 24 hours after early ( 〈 3 hours) but not after delayed ( 〉 3 hours) or no recanalization. Conclusion— The impact of admission HG on stroke outcome varies depending on the time to tPA-induced reperfusion. The detrimental effect of acute HG is higher after early than after delayed or no reperfusion. Ultra-early glycemic control before reperfusion may improve the efficacy of thrombolytic therapy.

    Abstract: Background and Purpose— Hyperglycemia (HG) has a deleterious effect in stroke patients by accelerating ischemic brain damage; moreover, its antifibrinolytic effect may also influence reperfusion. We aimed to study the effect of acute/chronic HG on tissue-type plasminogen activator (tPA)–induced recanalization. Methods— We studied 139 consecutive stroke patients with documented intracranial artery occlusion treated with intravenous tissue-type plasminogen activator (tPA). Admission glucose levels were recorded (in mg/dL). The existence of previous chronic HG was determined by plasma levels of glycosylated hemoglobin (HbA1c, %) and fructosamine (in μmol/L). Transcranial Doppler monitoring assessed complete recanalization 2 hours after tPA bolus. National Institutes of Health Stroke Scale (NIHSS) scores were obtained at baseline and 48 hours. Results— On admission, the median NIHSS score was 18 and mean glucose value was140±63 mg/dL. At 2 hours, 32% of patients(n=44) achieved complete recanalization. Patients who recanalized showed lower admission glucose levels (127 vs 146 mg/dL; P =0.039) but no differences in HbA1c (6.3% vs 6.3%; P =0.896) or fructosamine (292 vs 293 μmol/L; P =0.957) were observed. Other variables associated with recanalization were initial distal middle cerebral artery occlusion ( P =0.011) and platelet count ( P =0.015). Patients with an admission glucose level 〉 158 mg/dL had lower recanalization rates (16% vs 36.1%; P =0.035) and a higher NIHSS score at 48 hours (7 vs 14.5; P =0.04). After adjustment for stroke etiology, age, and risk factors, the only independent predictors on admission of no recanalization were glucose value 〉 158 mg/dL (odds ratio [OR], 7.3; 95% confidence interval [CI] , 1.3 to 42.3; P =0.027), proximal middle cerebral artery occlusion (OR, 2.6; 95% CI, 1.1 to 6.5; P =0.034), and platelet count 〈 219 000/mL (OR, 2.6; 95% CI, 1.1 to 6.1; P =0.029). Conclusions— In tPA-treated patients, the acute but not chronic HG state may hamper the fibrinolytic process, delaying reperfusion of the ischemic penumbra. Early measures to reduce HG may favor early recanalization.

    Abstract: Background and Purpose— The molecular pathways involved in the progression of intracranial large artery atherosclerosis (ILA) are largely unknown. Our objective was to prospectively study the relationship between circulating levels of inflammatory markers and fibrinolysis inhibitors, and the risk of progression of symptomatic ILA. Methods— Seventy-five consecutive patients with first-ever symptomatic intracranial atherostenosis were studied. Blood levels of C-reactive protein (CRP), E-selectin, monocyte chemoattractant protein-1, intercellular adhesion molecule-1, matrix metalloproteinases 1, 2, 3, 8, 9, 10, and 13, plasminogen activator inhibitor-1 (PAI-1), and lipoprotein(a) were measured 3 months after the qualifying stroke or transient ischemic attack. Thereafter, patients underwent long-term transcranial Doppler follow-up to detect progression of ILA. Results— During a median follow-up time of 23 months, 25 (33%) patients showed ILA progression. Multivariable adjusted Cox regression models and Kaplan–Meier curves showed that high baseline level of CRP, E-selectin, intercellular adhesion molecule-1, matrix metalloproteinase 9, PAI-1, and lipoprotein(a) predicted ILA progression independently of vascular risk factors. Of them, only CRP (CRP 〉 5.5 mg/L; HR, 5.4 [2.3 to 12.7]; P =0.0001) and PAI-1 (PAI-1 〉 23.1 ng/mL; HR, 2.4 [1.0 to 5.8]; P =0.05) predicted ILA progression also independently of the other studied molecules. Conclusion— Progression of symptomatic ILA is associated with a proinflammatory state, as reflected by high levels of inflammatory markers, and with defective fibrinolysis, as indicated by raised concentrations of endogenous fibrinolysis inhibitors.

    Abstract: Stroke is reported as a consequence of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection in several reports. However, data are sparse regarding the details of these patients in a multinational and large scale. Methods: We conducted a multinational observational study on features of consecutive acute ischemic stroke, intracranial hemorrhage, and cerebral venous or sinus thrombosis among SARS-CoV-2–infected patients. We further investigated the risk of large vessel occlusion, stroke severity as measured by the National Institutes of Health Stroke Scale, and stroke subtype as measured by the TOAST (Trial of ORG 10172 in Acute Stroke Treatment) criteria among patients with acute ischemic stroke. In addition, we explored the neuroimaging findings, features of patients who were asymptomatic for SARS-CoV-2 infection at stroke onset, and the impact of geographic regions and countries’ health expenditure on outcomes. Results: Among the 136 tertiary centers of 32 countries who participated in this study, 71 centers from 17 countries had at least 1 eligible stroke patient. Of 432 patients included, 323 (74.8%) had acute ischemic stroke, 91 (21.1%) intracranial hemorrhage, and 18 (4.2%) cerebral venous or sinus thrombosis. A total of 183 (42.4%) patients were women, 104 (24.1%) patients were 〈 55 years of age, and 105 (24.4%) patients had no identifiable vascular risk factors. Among acute ischemic stroke patients, 44.5% (126 of 283 patients) had large vessel occlusion; 10% had small artery occlusion according to the TOAST criteria. We observed a lower median National Institutes of Health Stroke Scale (8 [3–17] versus 11 [5–17] ; P =0.02) and higher rate of mechanical thrombectomy (12.4% versus 2%; P 〈 0.001) in countries with middle-to-high health expenditure when compared with countries with lower health expenditure. Among 380 patients who had known interval onset of the SARS-CoV-2 and stroke, 144 (37.8%) were asymptomatic at the time of admission for SARS-CoV-2 infection. Conclusions: We observed a considerably higher rate of large vessel occlusions, a much lower rate of small vessel occlusion and lacunar infarction, and a considerable number of young stroke when compared with the population studies before the pandemic. The rate of mechanical thrombectomy was significantly lower in countries with lower health expenditures.

    Abstract: Background and Purpose— We aimed to determine clinical and hemodynamic predictors of early reocclusion (RO) in stroke patients treated with intravenous tissue plasminogen activator (tPA). Methods— We studied 142 consecutive stroke patients with a documented middle cerebral artery (MCA) occlusion treated with intravenous tPA. All patients underwent carotid ultrasound and transcranial Doppler (TCD) examination before tPA bolus. National Institutes of Health Stroke Scale (NIHSS) scores were performed at baseline and serially for 〈 24 hours. TCD monitoring of MCA recanalization (RE) and RO was performed during the first 2 hours after tPA bolus and repeated when clinical deterioration occurred 〈 24 hours after documented RE in absence of intracranial hemorrhage. Results— After 1 hour of tPA administration, RE occurred in 84 (61%) patients (53 partial, 31 complete). Of these, 21 (25%) patients worsened after an initial improvement and 17 (12%) of them showed RO on TCD. RO was identified at a mean time of 65±55 minutes after documented RE. RO was associated ( P =0.034) with a lower degree of 24-hour NIHSS score improvement than sustained RE, and a higher modified Rankin scale score at 3 months ( P =0.002). Age older than 75 years ( P =0.012), previous antiplatelet treatment ( P =0.048), baseline NIHSS score 〉 16 points ( P =0.009), higher leukocytes count ( P =0.042), beginning of RE 〈 60 minutes after tPA bolus ( P =0.039), and ipsilateral severe carotid stenosis/occlusion ( P =0.001) were significantly associated with RO. In a logistic regression model, NIHSS score 〉 16 at baseline (odds ratio [OR], 7.1; 95% CI, 1.3 to 32) and severe ipsilateral carotid disease (OR, 13.3; 95% CI, 3.2 to 54) remained as independent predictors of RO. Conclusions— Stroke severity and ipsilateral severe carotid artery disease independently predict RO after tPA-induced MCA RE.

    Abstract: Background and Purpose— We aimed to evaluate the timing, speed, and degree of tissue plasminogen activator (tPA)–induced recanalization in patients with proximal middle cerebral artery (MCA) occlusion of different stroke subtypes. Methods— We evaluated 72 patients with acute stroke caused by proximal MCA occlusion treated with intravenous tPA in 〈 3 hours. Transcranial Doppler monitoring of recanalization was conducted during tPA infusion and at 6 hours. Strokes were categorized as large-vessel disease strokes, cardioembolic strokes, or strokes of undetermined origin according to Trial of Org 10172 in Acute Stroke Treatment criteria. Results— During 1-hour tPA infusion, recanalization occurred in 34 patients (47%); 32% showed a sudden, 50% showed a stepwise, and 18% showed a slow pattern of recanalization. One-hour recanalization was more frequent in patients with cardioembolic stroke (59%) compared with large-vessel disease (8%) and undetermined origin (50%) strokes. A cardiac source of emboli was identified in 81% of patients who showed a sudden clot breakup during tPA infusion. Rate of complete recanalization at 6 hours was higher ( P =0.006) in patients with cardioembolic stroke (50%) compared with other stroke subtypes (27%). Sudden recanalization was associated ( P =0.002) with a higher degree of neurological improvement at 24 hours compared with stepwise, slow, and no recanalization. A graded response in long-term outcome was observed in relation to the speed of clot lysis during tPA administration. Conclusions— We demonstrate that the pattern of tPA-induced MCA recanalization differs among stroke subtypes. Early recanalization was more frequent, faster, and more complete in patients with cardioembolic stroke compared with other stroke subtypes.
