THRIVE score predicts outcomes with a third-generation endovascular stroke treatment device in the TREVO-2 trial.

ABSTRACT: Several outcome prediction scores have been tested in patients receiving acute stroke treatment with previous generations of endovascular stroke treatment devices. The TREVO-2 trial was a randomized controlled trial comparing a novel endovascular stroke treatment device (the Trevo device) to a previous-generation endovascular stroke treatment device (the Merci device).We used data from the TREVO-2 trial to validate the Totaled Health Risks in Vascular Events (THRIVE) score in patients receiving treatment with a third-generation endovascular stroke treatment device and to compare THRIVE to other predictive scores. We used logistic regression to model outcomes and compared score performance with receiver operating characteristic curve analysis.In the TREVO-2 trial, the THRIVE score strongly predicts clinical outcome and mortality. The relationship between THRIVE score and outcome is not influenced by either success of recanalization or the type of device used (Trevo versus Merci). The superiority of the Trevo device to the Merci device is evident particularly among patients with a low-to-moderate THRIVE score (0-5; 53.8% good outcome with Trevo versus 27.5% good outcome with Merci). In receiver operating characteristic curve analysis, the THRIVE score was comparable or superior to several other outcome prediction scores (HIAT, HIAT-2, SPAN-100, and iScore).The THRIVE score strongly predicts clinical outcome and mortality in the TREVO-2 trial. Taken together with THRIVE validation data from patients receiving intravenous tissue-type plasminogen activator or no acute treatment, the THRIVE score has broad predictive power in patients with acute ischemic stroke, which is likely because THRIVE reflects a set of strong nonmodifiable predictors of stroke outcome.

Project description:The Totaled Health Risks in Vascular Events (THRIVE) score strongly predicts clinical outcome, mortality, and risk of thrombolytic haemorrhage in ischemic stroke patients, and performs similarly well in patients receiving intravenous tissue plasminogen activator, endovascular stroke treatment, or no acute treatment. It is not known if the THRIVE score predicts outcomes with the Solitaire endovascular stroke treatment device.To validate the relationship between the THRIVE score and outcomes after treatment with the Solitaire endovascular stroke treatment device.The study conducted a retrospective analysis of the prospective SWIFT and STAR trials to examine the relationship between THRIVE and outcomes after treatment with the Solitaire device. We examined the relationship between THRIVE and clinical outcomes (good outcome or death at 90?days) among patients in SWIFT and STAR. Receiver-operator characteristics curve analysis was used to compare THRIVE score performance with other stroke prediction scores. Multivariable modeling was used to confirm the independence of the THRIVE score from procedure-specific predictors (successful recanalization or device used) and other predictors of functional outcome.The THRIVE score strongly predicts good outcome and death among patients treated with the Solitaire device in SWIFT and STAR (Mantel-Haenszel chi-square test for trend P?<?0·001 for good outcome, P?=?0·01 for death). In receiver-operator characteristics (ROC) curve comparisons, totaled health risks in vascular events score is superior to Stroke Prognostication using Age and NIH Stroke Scale score-100 (P?<?0·001) and performed similarly to Houston Intra-Arterial Therapy score (HIAT) (P?=?0·98) and HIAT-2 (P?=?0·54). In multivariable models, THRIVE's prediction of good outcome is not altered after controlling for recanalization or after controlling for device used. The THRIVE score remains a strong independent predictor after controlling for the above predictors together with time to procedure, rate of symptomatic haemorrhage, and use of general anesthesia. Of note, use of general anesthesia was not an independent predictor of outcome in SWIFT?+?STAR after controlling for totaled health risks in vascular events and other factors.The THRIVE score strongly predicts clinical outcome and mortality in patients treated with the Solitaire device in the SWIFT and STAR trials. The lack of interaction between THRIVE and procedure-specific elements such as vessel recanalization or device choice makes the THRIVE score a reasonable candidate for use as a patient selection criterion in stroke clinical trials.

Project description:BackgroundTimely endovascular thrombectomy (EVT) significantly improves outcomes in patients with acute ischemic stroke (AIS) with large vessel occlusion type. However, whether certain central nervous system-specific plasma biomarkers correlate with the outcomes is unknown. We evaluated the temporal changes and prognostic roles of the levels of these biomarkers in patients with AIS undergoing EVT.MethodsWe enrolled 60 patients who received EVT for AIS and 14 controls. The levels of plasma biomarkers, namely neurofilament light chain (NfL), glial fibrillary astrocytic protein (GFAP), tau, and ubiquitin C-terminal hydrolase L1 (UCHL1), were measured with an ultrasensitive single molecule array before, immediately after, and 24 h after EVT (T1, T2, and T3, respectively). The outcomes of interest were death or disability at 90 days (defined as a modified Rankin Scale score of 3-6) and types of hemorrhagic transformation (hemorrhagic infarction or parenchymal hemorrhage).ResultsOf the 180 blood samples from the 60 patients who received EVT, the plasma NfL, GFAP, and UCHL1 levels at T1 were significantly higher than those of the controls, and the levels of all four biomarkers were significantly higher at T3. Patients with parenchymal hemorrhage had a significantly higher rate of increase in GFAP (Pinteraction = 0.005) and UCHL1 (Pinteraction = 0.007) levels compared with those without parenchymal hemorrhage. In a multivariable analysis with adjustment for age, sex, National Institute of Health Stroke Scale score, history of atrial fibrillation, and recanalization status, higher NfL levels at T1 (odds ratio [OR] 2.05; 95% confidence interval [CI], 1.03-4.08), T2 (OR, 2.08; 95% CI, 1.05-4.01), and T3 (OR, 3.94; 95% CI, 1.44-10.79) were independent predictors of death or disability at 90 days.ConclusionAmong patients with AIS who received EVT, those with hemorrhagic transformation exhibited significant increase in plasma GFAP and UCHL1 levels over time. Higher plasma NfL were predictive of unfavorable functional outcomes.

Project description:Background and purposeThe Interventional Management of Stroke (IMS)-III trial randomized patients with acute ischemic stroke to intravenous tissue-type plasminogen activator (tPA) plus endovascular therapy versus intravenous tPA therapy alone within 3 hours from symptom onset. A predefined secondary hypothesis was that subjects with significant early ischemic change on the baseline scan would not respond to endovascular therapy.MethodsThe primary outcome was 90-day modified Rankin Scale score 0 to 2. The baseline and follow-up computed tomographic (CT) scan images were reviewed centrally and blinded to any clinical information. We assessed whether the baseline Alberta Stroke Program Early CT Score (ASPECTS) predicted outcome and interacted with study treatment. We analyzed subgroups defined by time from onset to intravenous tPA initiation and baseline occlusion status at a prespecified α=0.01.ResultsBaseline demographic and clinical characteristics of 656 randomized patients were similar between subjects with a baseline ASPECTS 8 to 10 (58% of the study sample) versus 0 to 7. Subjects with ASPECTS 8 to 10 were almost twice as likely (relative risk, 1.8; 99% confidence interval, 1.4-2.4) to achieve a favorable outcome. There was insufficient evidence of a treatment-by-ASPECTS interaction. In those treated with onset to intravenous tPA <120 minutes, in CT angiography-proven internal carotid artery or middle cerebral artery occlusion, and in both, results were similar. The probability of achieving recanalization (arterial occlusion lesion, 2-3) of the primary arterial occlusive lesion (relative risk, 1.3; 99% confidence interval, 1.0-1.8) or achieving thrombolysis in cerebral ischemia score 2b/3 reperfusion (relative risk 2.0; 99% confidence interval, 1.2-3.2) was higher among subjects with higher ASPECTS.ConclusionsASPECTS is a strong predictor of outcome and a predictor of reperfusion. ASPECTS did not identify a subpopulation of subjects that particularly benefitted from endovascular therapy immediately after routine intravenous tPA.Clinical trial registration urlhttp://www.clinicaltrials.gov.

Project description:BACKGROUND AND PURPOSE:This study aims to describe the relationship between computed tomographic (CT) perfusion (CTP)-to-reperfusion time and clinical and radiological outcomes, in a cohort of patients who achieve successful reperfusion for acute ischemic stroke. METHODS:We included data from the CRISP (Computed Tomographic Perfusion to Predict Response in Ischemic Stroke Project) in which all patients underwent a baseline CTP scan before endovascular therapy. Patients were included if they had a mismatch on their baseline CTP scan and achieved successful endovascular reperfusion. Patients with mismatch were categorized into target mismatch and malignant mismatch profiles, according to the volume of their Tmax >10s lesion volume (target mismatch, <100 mL; malignant mismatch, >100 mL). We investigated the impact of CTP-to-reperfusion times on probability of achieving functional independence (modified Rankin Scale, 0-2) at day 90 and radiographic outcomes at day 5. RESULTS:Of 156 included patients, 108 (59%) had the target mismatch profile, and 48 (26%) had the malignant mismatch profile. In patients with the target mismatch profile, CTP-to-reperfusion time showed no association with functional independence (P=0.84), whereas in patients with malignant mismatch profile, CTP-to-reperfusion time was strongly associated with lower probability of functional independence (odds ratio, 0.08; P=0.003). Compared with patients with target mismatch, those with the malignant mismatch profile had significantly more infarct growth (90 [49-166] versus 43 [18-81] mL; P=0.006) and larger final infarct volumes (110 [61-155] versus 48 [21-99] mL; P=0.001). CONCLUSIONS:Compared with target mismatch patients, those with the malignant profile experience faster infarct growth and a steeper decline in the odds of functional independence, with longer delays between baseline imaging and reperfusion. However, this does not exclude the possibility of treatment benefit in patients with a malignant profile.
