Abstract:
Objective To compare the effect of two-dimensional strain imaging on evaluation of regional and global strain of right ventricle and hypertensive left ventriculaRhypertrophy in patients with hypertrophic cardiomyopathy.Methods A total of 100 cases were selected,in which 41 cases with hypertensive left ventriculaRhypertrophy were designed as observation group and 59 cases of hypertrophic cardiomyopathy were designed as study group.The left ventriculaRend diastolic diameter,left ventriculaRposterioRwall thickness,right ventriculaRfractional area change,right ventriculaRbasal dimension tracing,wall thickness of inter-ventriculaRseptum,tricuspid annulaRplane systolic execution,right ventriculaRregional and global longitudinal strain by two-dimensional strain imaging were compared between the two groups.Results The left ventriculaRend diastolic diameteRin the study group was significantly loweRthan the observation group (P<0.05),while the left ventriculaRposterioRwall thickness was significantly higheRthan the observation group (P<0.05).The right ventriculaRfractional area change and tricuspid annulaRplane systolic excution showed no significant difference between the two groups (P>0.05).The right ventriculaRbasal dimension tracing and wall thickness of inter-ventriculaRseptum in the study group were significantly loweRthan the observation group (P<0.05).The regional and global strain in the study group were significantly higheRthan the observation group (P<0.05).Conclusion Compared with hypertensive left ventriculaRhypertrophy,the two-dimensional strain imaging is more helpful foRindicating the presence of right ventriculaRfunction reconstructing in patients with hypertrophic cardiomyopathy.
