3.GOAL,HYPOTHESISANDSPECIFICAIMSTheoverallgoalofthisstudyistoelucidatelong‐termoutcomesofpatientswithmildandrapidly improving stroke and examine the association with tPA treatment. In order toaccomplishthisgoal,wewillpursuethefollowingspecificaims:SpecificAim1.Determinethe90‐dayoutcomesforpatientswithmildstrokesymptomsorrapidly improvingstrokesymptoms.Wehypothesize thatasubgroupofpatientswithmildstrokesymptomsdefinedbytheNIHSS,orwithrapidlyimprovingsymptoms,willhavepooroutcomes.Thepopulationtobestudiedisaprospectivecohortof2650patientsat100GWTG‐Spreselectedhospitalswithmildischemicstroke(NIHSS=or<5)orrapidlyimprovingstrokesymptomswithin4.5hours fromonset,whichprovide informedconsent,andspeakEnglishorSpanish.Outcomeswillbeobtainedthroughastructuredtelephoneinterviewwiththepatientorproxy. Theprimaryoutcome is theproportionofpatientswith amodifiedRankinScore (mRS)=or>2at90days.Secondaryoutcomes include:Barthel Index (BI),StrokeImpactScale(SIS),EuroQOL,at90days,mRSat30days,mortalityat30and90days.SpecificAim1b.Determinethereliabilityofanautomatedpatientreportedoutcome(PRO).WehypothesizethatanautomatedPROisfeasibleandreliable.Asubsetof100patientswithinternetaccesswillbeinvitedtocompleteaweb‐basedPROthatincludesthemRS,BI,SIS‐16,andEuroQOL,whichwillbecomparedtothetelephoneinterview.SpecificAim2.Determinethepredictorsforworse90‐dayoutcomesinpatientswithmild stroke symptoms or rapidly improving stroke symptoms. We hypothesize thatcertain variables can predict poor outcomes. Prediction models will use current GWTG‐Sdemographic, risk factor, and clinicalpresentationvariables, aswell asnewly collected in‐hospitalvariables(individualcomponentsofthebaselineNIHSS,serialin‐hospitalNIHSS,andstrokemechanism.Specific Aim 3. Among patients withmild or rapidly improving stroke symptoms,compare the safetyandefficacyoutcomesof intravenous thrombolysiscompared tonon‐thrombolyzedpatientsafteradjusting for treatmentpredictors. Thehypothesis isthatanalysisoftheinteractionbetweenpredictorsofpooroutcomeandIVrtPAtreatmentcanidentifyasubgroupofpatientswithmildandrapidly improvingstrokesymptomsthatcanpotentiallybenefitfromthrombolytictherapy.Weanticipatethatabout10%ofthepopulationstudiedwillbetreatedwithIVrtPA.Theprimaryefficacyoutcome:mRS0‐1at90‐days.Theprimarysafetyoutcomeissymptomatichemorrhagictransformation.Secondaryoutcomesinclude:90‐dayBI,EuroQOL,andSIS‐16,endovascularacutestrokerescuetreatmentwithin24hours.

4.BACKGROUNDANDRATIONALEStrokeisthe5thcauseofdeathintheUSand3rdcauseofdeathworldwide,aswellasaleadingcauseofdisability(1).PopulationbasedstudiesrevealthatabouthalfofallstrokeshavelowNIHSSonpresentation(2,3).Mildandrapidlyimprovingstrokesareacommonreasontonotadminister thrombolytics, although up to one third of patients with mild and rapidlyimprovingstrokesareunabletoreturnhome.Nonetheless,detailed long‐termoutcomesinthosewithmildandorrapidly improvingstrokeare lacking.This isessential todeterminewhethermoreaggressivetreatmentisreasonableforsomethesepatients.Howaremildandrapidlyimprovingsymptomsdefined?Traditionally,theNIHSShasbeenusedtodescribeaseverityofastroke.Mostrecentclinicalstudiesofinterventionforacuteischemicstroke have excluded those with an NIHSS <5 or <6. However, in clinical practice, thedeterminationofmildstrokeasareasonnottoadministerIVrtPAisleftuptotheclinician.Amongst10,295GWTG‐Spatientsnot treatedwithIVrtPAsolelybecauseofamildstroke,94%hadaNIHSSof5orless(4).However,itisclearthatanisolatedaphasicsyndrome,eventhoughitwouldaccruealowNIHSS,wouldbequitedisablingandwouldnotbeconsideredmild.The situation of rapidly improving symptoms is more complicated. Different studies andreportshavedefinedimprovementbytheabsolutechangeinNIHSSpointsfrombaseline,thefinal NIHSS score, or the percent improvement in the NIHSS (5‐10). A recent consensusstatementrecommendeddefiningrapidlyimprovingstrokesymptomsasthosethatimprovetoanNIHSS<5andarenon‐disabling(11).However,alargeproportionoftheimprovementmayoccurpriortohospitalarrival.AlthoughanumberofEMSscalesofseverityareavailable,theyhavenotbeencarefullyanalyzedtoincludepre‐hospitalfluctuationsinthedefinitionofrapidly improvingstroke.Therefore, inpractice, thephysicianascertains ifsymptomshaverapidlyimprovedornot.InGWTG‐S,amongstthosenottreatedduetoonlyrapidlyimprovingsymptoms,26%hadanNIHSS>5suggestingpersistentdisablingsymptomatology(4).Aremildstrokeandrapidlyimprovingstrokesimilar?Althoughtheremaybeoverlapbetweenmildandrapidlyimprovingstroke,withasmanyas1in4patientsrapidlyimprovingtoamildlevel, these conditions have clearly different causes, presentations and outcomes. Rapidimprovementwould suggest rapid recanalizationand reperfusionof ischemic tissue,whilemildstrokesareprobablycausedbypersistentocclusionofavessel.Inaretrospectiveanalysisof GWTG‐S, rapidly improving stroke patients tended to be older, havemore cardiac andcarotiddisease,andhaveahigherNIHSSatbaseline.Afteradjustmentformultiplevariables,rapidly improving strokes that improve to mild had the best outcomes. Therefore, eachcategory(mild,rapidlyimproving,andrapidlyimprovingtomild)hasdistinctcharacteristics.Howcommonaremildandrapidlyimprovingstrokesymptoms?About31‐46%ofpatientsthatpresenttotheEmergencyDepartmentwithin3hoursofonsetwithanacuteischemicstrokehavemildorrapidlyimprovingstrokesymptoms(12‐15).ThelargestavailableseriesincludethelargeGWTG‐Sregistrywhere31.2%of93,517patientsthatarrivedwithin2hoursofonsetwere not treated with intravenous thrombolytics (IV rtPA) because of mild or improvingstroke(14),andthe4‐statePaulCoverdellregistry,inwhichmildorrapidlyimprovingstroke

symptomswerethemaincauses(46.6%)forbeingconsideredineligibleforIVrtPAinthosearrivingwithin2hoursfromsymptomonset(15).What are the outcomes ofmild and rapidly improving stroke symptoms that donot receivethrombolytictherapy?Mostdatacomesfromregistriesorretrospectiveanalysisthatvaryinthedefinitionofmildandrapidlyimprovingstroke.InGWTG‐S,amongst29,200patientswithmildandrapidlyimprovingstrokenottreatedwithIVrtPA,27%wereunabletoreturnhome,and29%couldnotambulateindependentlyatdischarge.Smallserieshaveshownthatat3months,amRSof2‐6waspresentin15%(16)to32%(17).Therefore,asmanyasonethirdhavesuboptimaloutcomes.However,detailedlongtermoutcomesarelackingforthiscohortofpatients.HowmanymildandrapidlyimprovingstrokepatientsreceiveIVrtPA?Alteplaselabelingandprior strokeguidelines (18) recommendagainst IV rtPAadministrationwhenneurologicalsigns are clearing spontaneously and when neurological signs are minor and isolated.However,newerguidelinesrecognizethatsomeofthesepatientsmayhavepooroutcomesandthereforerecommendtreatmentofmildbutdisablingstrokewithin3hoursofsymptomonset(19).Thiscoincidedwitharevisionofthealteplaseprescribinginformationin2015thatdoesnotincludetheseexclusions.Althoughtreatmentatacademicorhighvolumescentersreportthatasmanyas21%ofmildstrokesreceiveIVrtPAtreatment(4,20),nationalregistriesshowmoremodestratesof10%to12%(21,22).DothosethatreceiveIVrtPAdobetterthanthosethatareuntreated?Thisisanopenquestionand the subject of ongoing research. It is difficult to compare outcomes outside of arandomizedcontrolledtrialasthereisthepotentialforbias(confoundingbyindication);thatis,specifichigherseveritymarkersmayguidethecliniciantoadministerIVrtPAtoonepatientbut not to another. The largest report suggests that although the risk of symptomatichemorrhageis<2%,outcomesatdischargewerepoor,with29%notdischargedhomeand31% unable to ambulate independently at discharge (4). Delayed 3‐month outcomes areavailableonlyfromsmallseriesshowingmRS2‐6in17%(23)to42%(24).Whatunderliespooroutcomesinmildandrapidlyimprovingstroke?PooroutcomesmaybeduetoanisolatedbutdisablingsymptomsuchasaphasiathatmaynottranslateintoahighNIHSSscore(25).Also,earlyprogressionofmildsymptomsisnotuncommon.Asinglecenterstudyreportedthat8.3%of229patientswithamildstrokeorTIA(NIHSS<5)hadprogressionofsymptomswithin72hours,similartothosewithmoreseverestrokes(26).Similarly, inanMRIbasedstudy,10%of thoseexcluded fromthrombolytic therapy formildor improvingsymptoms had early neurologic deterioration and infarct expansion and 20% had poordischargeoutcome(27).Rapidlyimprovingsymptomsmaysubsequentlydeteriorate.Smithandcolleagues(28)reportedthat11/41patientswithmild/improvingsymptomsnottreatedwith tPA were not discharged home; 6 of them had early worsening. Early worsening isthought to be due to hemodynamic failure, or re‐occlusion of a spontaneously reanalyzedvessel, whichmay occur in 12% of all tPA‐treated patients and 27% of thosewith initialrecanalization(29).AnORof4.1 forsubsequentdeteriorationwasdescribedinthosewithrapidlyimprovingsymptomscomparedtothosewithoutrapidimprovement(28).

More detailed outcomemeasures are needed to better understand functionaloutcomesaftermildandrapidlyimprovingstroke.OthermeasuresalsoemployedinMaRISSassecondaryoutcomesincludetheBarthel Index(BI), theStrokeImpactScale‐16(SIS‐16),andEuroQOL(EQ‐5D).TheBImeasuresactivitiesofdailyliving;ascoreof>85correspondstoindependencewithminimalassistance,whileascore>95tominimalornodisability(32‐34). The SIS‐16 concentrates on the physical domains rather than cognitive or emotionaldomains (31,35,26). The EQ‐5D measures health outcomes and explores non‐physicaldomains(37,38).Canpooroutcomesbepredictedatbaselineevaluation?Wehaveassessedpredictorsofpooroutcome inmildandrapidly improvingstroke inGWTG‐S,andfoundthatolderage,AfricaAmericans, the greater burden of stroke risk factors such as hypertension, diabetes, priorstroke, atrial fibrillation, heart failure and peripheral vascular disease, as well as delayedarrivalandhigherNIHSSareassociatedwithworsedischargeoutcomes,whilethebaselineuseofantiplatelet,antihypertensiveandantilipidemicmedicationwasassociatedwithbetteroutcomes.Othershavefoundthatlargevesselocclusionanddistalhypoperfusionpredictedstrokeprogression(27,39).However,theinfluenceofstrokemechanismandearlyin‐hospitalfluctuationsonoutcomesisnotcurrentlyknown.SummaryofbackgroundforMaRISS.Mildandrapidlyimprovingstrokesymptomsarecommonpresentationsofacute ischemicstroke.Thegreatmajorityofpatientsarenot treatedwiththrombolytics.Theoutcomesofmildandrapidlyimprovingstrokearesuboptimalwithalmost1 in 3 unable to return home or ambulate independently at discharge. Nevertheless,continuousimprovementmayoccurinthefirst3monthsafterdischarge(40),but3‐monthoutcomesareavailable fromonlysmall series, includeonly themRS,andvaryextensively.Therefore,thelong‐termoutcomesandpredictorsofpooroutcomearenotwellcharacterized.MaRISSwilldescribethelong‐termoutcomeswithabatteryofsensitiveoutcomemeasures,and will elucidate predictors of poor outcome by carefully analyzing stroke baselinecharacteristicsandearlyfluctuations.
