国际精神病学杂志JOURNALOFINTERNATIONALPSYCHIATRY2023年第50卷第3期-434-◎临床研究◎Clinicalresearch不同剂量的奥氮平对精神分裂症患者心电图及心肌酶的影响张珉【摘要】目的探讨不同剂量奥氮平对精神分裂症患者心电图及心肌酶的影响。方法本研究选择2021年2月~2022年8月86例精神分裂症患者为观察对象,根据奥氮平服药剂量设为低剂量组(≤10mg/d)以及高剂量组(>10mg/d),分别为48例、38例,比较治疗期间窦性心动过速、ST段改变等异常心电图发生情况以及治疗前后血清肌酸激酶(CK)、乳酸脱氢酶(LDH)以及肌酸激酶同工酶(CK-MB)等心肌酶水平。结果高剂量组窦性心动过速、ST段改变、窦性心律不齐、T波改变等异常心电图发生率显著高于低剂量组(P<0.05),两组窦性心动过缓、Q-T间期延长等发生率差异无统计学意义(P>0.05);两组治疗后血清CK、LDH、CK-MB水平均显著升高,且治疗后高剂量组显著高于低剂量组(P<0.05)。结论奥氮平治疗精神分裂症均会造成一定的心脏副作用,但高剂量奥氮平引起的心电图的异常以及心肌酶水平升高情况更显著。【关键词】不同剂量;奥氮平;精神分裂症;心电图;心肌酶【中图分类号】R749.053【文献标识码】A【文章编号】1673-2952(2023)03-0434-03EffectsofdifferentdosesofolanzapineonelectrocardiogramandmyocardialenzymesinpatientswithschizophreniaZHANGMin.FourthPeople'sHospitalofLiaochengCity,Liaocheng252000,China【Abstract】ObjectiveToexploretheeffectofdifferentdosesofolanzapineonelectrocardiogramandmyocardialenzymesinpatientswithschizophrenia.MethodsEighty-sixschizophrenicpatientsfromFebruary2021toAugust2022wereselectedasthestudysubjects.Accordingtothedosageofolanzapine,48casesand38casesweredividedintolow-dosegroup(≤10mg/d)andhigh-dosegroup(>10mg/d).TheoccurrenceofabnormalECGsuchassinustachycardiaandSTsegmentchangesduringtreatmentandthelevelsofserumcreatinekinase(CK),lactatedehydro-genase(LDH)andcreatinekinaseisoenzyme(CK-MB)werecomparedbeforeandaftertreatment.ResultsTheinci-denceofabnormalECGsuchassinustachycardia,STsegmentchanges,sinusarrhythmiaandTwavechangesinthehigh-dosegroupwassignificantlyhigherthanthatinthelow-dosegroup(P<0.05).Therewasnosignificantdifferenceintheincidenceofsinusbrad...
