| 摘 要： | 目的应用超声心动图分析肥厚型心肌病(hypertrophic cardiomyopathy,HCM)左室流出道压力阶差(LVOTPG)与左心房(LA)大小的关系.方法随机选择肥厚梗阻性心肌病(HOCM)45例、肥厚型非梗阻性心肌病(HNOCM)40例、正常人52例,分别测量左室流出道(LVOT)宽度、左室流出道压力阶差(LVOTPG)及左心房的大小.结果正常对照组LVOT的宽度18.2 mm,LVOTPG 8.76 mm Hg,LA31.5 mm;HNOCM组LVOT的宽度15.18 mm,LVOTPG 13.13 mm Hg,LA 39.12 mm;HOCM组LVOT的宽度 9.28 mm,LVOTPG 38.74 mm Hg,LA 43.21 mm.结论 HOCM患者LVOTPG对左房功能的影响较HNOCM患者大,而与正常人相比对左房功能的影响更加明显.

Relationship Between Left Ventricular Out Tract Pressure Gradients and Left Atrium Width in Hypertrophic Cardiomyopathy:A Comparative Echocardiographic Study |
| |
| Abstract: | Objective To analyze the relationship between the pressure gradient of left ventricular out Tract(LVOTPG)and the width of left atrium(LA)in hypertrophic cardiomyopathy(HCM)using echocardiography.Methods Fourty five cases with hypertrophic obstructive cardiomyopathy(HOCM),40 cases with hypertrophic nonobstructive cardiomyopathy(HNOCM)were randomized selected and 52 subjects selected as normal control group.The width of LVOT,LVOTPG and the width of LA were meausred in all the 3 groups.Results The width of LVOT,LVOTPG and LA width in HOCM,HNOCM and normal groups were 9 28 mm,38 74 mm Hg,43 21 mm;15 18 mm,13 13 mm Hg,39 12 mm;18 12 mm,8 76 mm Hg,36 5 mm respectively.Conclusions The influence of LVOTPG on the left atrial function in HOCM is more significant than that of HNOCM group,and the most significant than that of the control group(All P <0 05). |
