Abstract:
Objective:To explore the diagnostic value of cardiac color Doppler ultrasonography for left ventricular hypertrophy(LVH)complicated left heart failure(LHF).Methods:A total of 117 LVH patients complicated LHF admitted in Ningde City Hospital Affiliated to Ningde Normal College between January 2019 and January 2023(heart failure group)and 100 healthy people(control group)who underwent general physical examination in our hospital simultaneously were selected for the study.Left ventricular ejection fraction(LVEF),left atrial diameter(LAD),left ventricular end-diastolic diameter(LVEDd),early diastolic peak flow velocity/late diastolic peak flow velocity(E/A)were measured by cardiac color Doppler ultrasound in two groups.Receiver operating charac-teristic(ROC)curve was used to analyze the diagnostic value of cardiac color Doppler ultrasound indexes for LVH complicated LHF.In addition,the 117 patients with LVH and LHF were divided into mild group(n=54)and moderate to severe group(n=63)according to cardiac function class.Spearman correlation analysis was used to an-alyze the associationof cardiac color ultrasound parameters with cardiac function class.Results:Compared with par-ticipants in control group,those in heart failure group had significant lower LVEF[(47.88±4.75)% vs.(69.81±5.64)%],and significant higher LAD[(44.03±4.88)mm vs.(27.56±2.76)mm vs.],LVEDd[(55.68±5.04)mm vs.(42.19±1.38)mm],E/A[(13.04±3.58)vs.(6.60±1.67)](P<0.001 all).ROC analysis indicated that the area under the curve(AUC)of the combination of various parameters of cardiac ultrasound for diagnosing LVH with LHF was significantly higher than those of the single tests(Combined detection:AUC=0.901,95%CI 0.853~0.937 vs LVEF:AUC=0.644,95%CI 0.577~0.708,LAD:AUC=0.703,95%CI 0.637~0.763,LVEDd:AUC=0.633,95%CI 0.565~0.697,E/A:AUC=0.748,95%CI 0.685~0.804,Z=7.062,5.764,7.292,4.864,P<0.001 all).Compared with patients in mild group,those in moderate to severe group had signifi-cant lower LVEF[(45.67±3.37)% vs.(50.47±4.86)%],and significant higher LAD[(46.31±4.42)mm vs.(41.36±3.98)mm],LVEDd[(60.09±1.75)mm vs.(50.53±1.41)mm]and E/A[(13.99±2.96)vs.(11.93±3.92)](P<0.01 all).Spearman correlation analysis indicated that LVEF was negatively correlated with cardiac function class(r=-0.474),while LAD(r=0.511),LVEDd(r=0.863),E/A(r=0.269)were positively corre-lated with cardiac function class(P<0.01 all).Conclusion:Cardiac color Doppler ultrasound could better diagnose LVH complicated LHF,and also could effectively predict the cardiac function of patients with LVH and LHF.
