Abstract:
Purpose To explore the characteristics of left and right ventricular myocardial strain in hypertensive heart disease(HHD)assessed by magnetic resonance feature tracking technique,and to assess the effect of HHD on right ventricular function.Materials and Methods A retrospective analysis was performed on 40 patients with HHD at the General Hospital of Ningxia Medical University from January 2022 to August 2023.Among these 40 HHD patients,19 presented with a left ventricular ejection fraction(LVEF)of≥50%,and 21 presented with an LVEF of<50%.Additionally,25 healthy controls were enrolled.All subjects underwent cardiac magnetic resonance imaging.The cine sequence images were imported into cardiac post-processing analysis software(QIR suite software).The left ventricular radial strain(LVRS),left ventricular circumferential strain(LVCS),left ventricular longitudinal strain(LVLS)and right ventricular longitudinal strain(RVLS)were measured,and left and right ventricular strain parameters of the three groups were analyzed statistically.Results The absolute values of LVRS,LVCS,LVLS and RVLS in the HHD group with LVEF<50%were lower than those in the normal control group(t=7.48,-12.69,-8.19,-6.32,all P<0.001)and those in the HHD group with LVEF≥50%(t=5.97,-8.88,-4.50,-4.90,all P<0.001);the area under the curve values of LVRS,LVCS,LVLS and RVLS for distinguishing HHD from normal controls were 0.804,0.785,0.829,0.832,respectively,and the cut-off values of LVRS,LVCS,LVLS and RVLS were 22.9%,-10.0%,-11.9%and-18.7%,respectively.Conclusion Magnetic resonance feature tracking technique can detect left and right ventricular myocardial dysfunction in HHD at an early stage and can provide a new basis for evaluating cardiac function.
