高血壓合并冠心病患者的左心室功能與升主動脈內徑相關性的臨床病例分析高血壓合并冠心病患者的左心室功能與升主動脈內徑相關性的臨床病例分析

摘要：

目的：檢測高血壓合并冠心病（HypertensionandCoronaryHeartDisease，HCHD）患者的左心室功能和升主動脈內徑之間的相關性，并探討其診斷和治療。

方法：選取2016年至2021年在本院接受治療的HCHD患者70例，分別觀察其左心室功能和升主動脈內徑，以超聲心動圖為主要檢查手段，進行相關性分析，同時分析患者臨床特征、心電圖及其他生理指標。

結果：HCHD患者左心室功能與升主動脈內徑呈顯著相關性（P<0.05），其中左心室收縮末期內徑（LVIDs）與升主動脈內徑呈正相關，左心室舒張末期內徑（LVIDd）與升主動脈內徑呈負相關。同時，HCHD患者的心電圖、血壓、心功能等方面表現都與升主動脈內徑有一定的相關性。

結論：HCHD患者的左心室功能受到升主動脈內徑的影響，升主動脈內徑的變化可以反映HCHD患者的左心室功能狀態和心血管疾病進展程度。因此，在HCHD患者的診療中，應該重視升主動脈內徑的監測和評估，同時加強心血管疾病的預防和治療。

關鍵詞：高血壓合并冠心病，左心室功能，升主動脈內徑，超聲心動圖，相關性分析。

Abstract:

Objective:Toinvestigatethecorrelationbetweenleftventricularfunctionandascendingaorticdiameterinpatientswithhypertensionandcoronaryheartdisease(HCHD),andtoexploreitsdiagnosisandtreatment.

Methods:70patientswithHCHDtreatedinourhospitalfrom2016to2021wereselected,andtheirleftventricularfunctionandascendingaorticdiameterwereobservedrespectively.Correlationanalysiswasperformedbyultrasoundechocardiographyasthemainexaminationmethod,andclinicalcharacteristics,electrocardiogramandotherphysiologicalindicatorswerealsoanalyzed.

Results:TherewasasignificantcorrelationbetweenleftventricularfunctionandascendingaorticdiameterinpatientswithHCHD(P<0.05),ofwhichtheleftventricularend-systolicdiameter(LVIDs)waspositivelycorrelatedwithascendingaorticdiameter,whiletheleftventricularend-diastolicdiameter(LVIDd)wasnegativelycorrelatedwithascendingaorticdiameter.Atthesametime,theelectrocardiogram,bloodpressureandcardiacfunctionofHCHDpatientswerealsorelatedtoascendingaorticdiameter.

Conclusion:LeftventricularfunctionofpatientswithHCHDisaffectedbyascendingaorticdiameter,andchangesinascendingaorticdiametercanreflecttheleftventricularfunctionstatusanddegreeofcardiovasculardiseaseprogression.Therefore,inthediagnosisandtreatmentofHCHDpatients,attentionshouldbepaidtomonitoringandevaluatingtheascendingaorticdiameter,andtopreventandtreatcardiovasculardiseases.
