本文研究肥厚型心肌病的超声心动图改变特点。受试对象包括32例患者和32例正常人,M型超声心动图检查按美国标准,二维超声心动图检查依Kolter氏法。资料表明,肥厚型心肌病超声心动图的主要改变为:室间隔/左室后壁厚度比>1.3,室隔厚度增加(16.2±2.7mm);左房扩大(36.4±5.5mm)和左室内径缩小(舒张末径43.1±5.8mm)。较少见的改变是二尖瓣前叶收缩期向前运动(SAM,37.5％)和主动脉瓣收缩中期关闭(28.1％),M型和二维心动图测量房室内径相关性甚好(r=0.87～0.94,P<0.001)。作者探讨心动图和临床表现之间的联系,具有SAM的患者均有严重胸痛和晕厥,胸骨左缘有收缩期喷射性杂音(第三、四肋隙);可能与左室—主动脉压力阶差有关,其他心动图改变和临床表现之间未发现直接联系。
This article studies hyperthyroid cardiomyopathy echocardiography changes characteristics. Subjects included 32 patients and 32 normal subjects. M-mode echocardiography was performed according to U.S. standards and two-dimensional echocardiography was performed by Kolter’s method. The data showed that the main changes of echocardiography of hypertrophic cardiomyopathy were: the ratio of interventricular / left ventricular wall thickness> 1.3, the increase of ventricular septum thickness (16.2 +/- 2.7mm); the enlargement of left atrium (36.4 +/- 5.5mm) and the left ventricular Diameter reduction (diastolic diameter 43.1 ± 5.8mm). Less common changes were mitral valve anterior systole forward movement (SAM, 37.5%) and aortic valve contracting mid-term closure (28.1%), and M-mode and two-dimensional cardiometry were associated with atrioventricular diameter r = 0.87 ~ 0.94, P <0.001). The authors explored the link between cardiogram and clinical manifestations. Patients with SAM had severe chest pain and syncope. Systolic ejection murmurs (third and fourth rib spaces) were found on the left side of the sternum, possibly related to left ventricular-aortic pressure Poor, no direct correlation between other cardiogram changes and clinical manifestations.
