摘要
目的探讨缩窄性心包炎患者组织应变成像的特征及其诊断价值。方法对26例缩窄性心包炎患者、30例对照者,在心尖四腔观组织多普勒图上同步定量显示室间隔和左室侧壁的中段应变曲线图,测量收缩期最大应变值。计算室间隔与左室侧壁最大应变量的绝对值及应变比值。结果缩窄性心包炎患者左室侧壁应变明显小于室间隔[(-5.60±3.46)%对(-14.14±4.11)%,P<0.05];应变差绝对值及比值明显高于对照组[差值(16.40±5.05)%对(3.26±1.95)%,比值5.97±5.67对1.12±0.37,P<0.05]。结论缩窄性心包炎患者应变曲线特征明显,直观易辨,有重要的诊断价值。
Objective To investigate the characteristics and the diagnostic value of the tissue strain imaging in constrictive pericarditis （CP）. Methods Twenty-six patients and thirty controls underwent comprehensive echocardiography with apical four chamber tissue Doppler imaging and strain imaging. Peak strain of the middle segments of the inter-ventricle septum and left ventricular lateral wall was recorded. The peak strain difference and strain ratio between the two segments were calculated. Results In patients with CP peak strain of the left ventricle lateral wall was significantly lower than that of the septum[-（ - 5.60±3.46） % vs （ - 14.14 ± 4. 11 ） %, P d0. 053 ;The strain difference and the strain ratio between the two segments were higher markedly in patients than in controls [difference （16.4± 5.05）% vs （3.26±1.95）%,ratio 5.97 ±5.67 vs 1.12±0.37, P〈0. 053. Conclusions The strain curve of the patients with CP was very distinctive, the peak strain value of the left ventrieular lateral wall was significantly lower than the septum. This is an objective and easy distinguished sign as an important diagnostic value.
