ObjectivesToevaluatetheeffectofdifferentstylesofcoronaryheartdisease(CHD),differentregionsofacutemyocardialinfarction(AMI),itsriskfactorsandbranchesofcoronarystenosisonleftventricularremodelinganddysfunctionbyapplyingechocardiography.Methods251patientswithCHDand96patientswithoutCHD(NoCHD)wereverifiedbyselectivecoronaryangiography.CHDpatientsweredividedintostableanginapectoris(SAP)26,unstableanginapectoris(UAP)53,acutemyocardialinfarction(AMI)140andoldmyocardialinfarction(OMI)30basedonclinicalsituation,cTnT,cardiacenzymeandEGG.AMIpatientswerefurtherdividedintosubgroupsincludingacuteanteriormyocardialinfarct(Aa,n=53),acuteinferiormyocardialinfarction(Ai,n,=54)andAa+Ai(n=33)basedonECG.Cardiacparameters:end-diastolicinterventricularseptumthickness(IVSd),end-diastolicleftventricularinternaldiameter(LVd),leftventricularmass(LM),end-diastolicleftventricularvolume(EDV),end-systolicleftventricularvolume(ESV)andleftventricularejectionfraction(LVEF)weremeasuredbyACUSON128XP/10echocardiography.MultipleslinearregressionanalyseswereperformedtoteststatisticalassociationsbetweenLVEFandtheinvolvedbranchesofcoronarystenosis,bloodpressure,lipids,glucoseandetcafteronsetofmyocardialinfarction.ResultsEDVandESVwereincreasedandLVEFdecreasedonpatientswithAMI,OMIandUAP(P<0.05-0.0001).LMwasmainlyincreasedinpatientswithOMI(P<0.01)andLVdwasmainlyenlargedinpatientswithAMI.EFwassignificantlydecreasedandEDV,ESV,LMandLVdwereremarkablyincreasedinAMIpatientswithAaandAa+Ai.WiththemultiplelinearregressionanalysesbySPSSsoftware,wefoundthatLVEFwasnegativelycorrelatedtotheinvolvedbranchesofcoronarystenosisaswellastosystolicbloodpressureafteronsetofmyocardialinfarctionwhiletherewasnosignificantcorrelationbetweenLVEFandotherfactors.LVEFwassignificantlydecreased,and
