| 目的 探讨心肌梗死情况下左室假腱索(LVFT)在维持左心室形态、减轻心脏重塑方面的作用。方法 60例前壁或广泛前壁心肌梗死患者分成左室假腱索组(LVFT组,n=21)和非左室假腱索组(NLVFT组,n=39)。应用二维超声心动图(2DE)观察左室射血分数(EF)、节段性左室壁运动障碍总积分(SWMST)、左室舒张末期内径(LVEED)、左室舒张末期短长径比率(SLR)。结果 在主要临床特征差异无显著性前提下,LVFT组及NLVFT组EF分别为(51.6±8.5)%和(43.2±9.3)%(P<0.01),SWMST分别为22.61±4.67和26.77±4.82(P<0.01),LVEDD分别为51.61±4.75和57.33±6.34(P<0.01),SLR分别为0.55±0.04和0.64±0.06(P<0.01)。结论 LVFT的存在可能在一定程度上减少左室前壁大面积心肌梗死后的心脏重塑。 |

| Objective To examine left ventricular false tendons (LVFT) for the limitation of ventricular remodeling in extensive anterior myocardial infarction. Methods Sixty patients with anterior myocardial infarction were divided into 2 groups: patients with LVFT (LVFT, n=21) and with non-LVFT (NLVFT, n=39). Two-dimensional echocardiography (2DE) was performed to evaluate left ventricular ejection fraction (EF), total segmental wall motion score (SWMST), left ventricular end-diastolic diameter (LVEED) and left ventricular short and long axis ratio (SLR). Results In the settings of comparable clinical features between groups of LVFT and NLVFT, EFs of the two groups were (51.6±8.5)% and (43.2±9.3)% (P<0.01), SWMSTs were 22.61±4.67 and 26.77±4.82 (P<0.01), LVEDDs were 51.61±4.75 and 57.33±6.34 (P<0.01), SLRs were 0.55±0.04 and 0.64±0.06, respectively (P<0.01). Conclusion LVFT may limit left ventricular remodeling after extensive anterior myocardial infarction. |
