Results The patients with cardiac amyloidosis had characteristics of large atriums and hypertrophic ventricular walls in echocardiography. And they also had low limb lead voltage in ECG. The ratio of (SV5+RV1) and left ventricle crossing area of all patients were obviously lower than 1.5. Biopsy behaved staining of congo red. And most patients had renal, dermatic and gastrointestinal involvements.

左旋心和孤立左位心的诊断主要依靠肺门切层片或高KV胸片和胸腹部平片。

objective trimetazidine has shown anti-ischemic properties to improve exercise tolerance without haemodynamic effects and direct cyto protective effect on the myocardium.however,it is not clear whether trimetazidine has beneficially effect on severe ischemic cardiomyopathy.methods 19patients（68±9）years with postnecrotic left ventricular dysfunction（ejection fraction31.7%±5.4%）were studied to examine the benefit of adding60mg a day of trimetazidine for3months to the classical therapy.the assessment included clinical evaluation,electrocardiography and echocardiography.results after adding60mg a day of trimetazidine for3months,attack of angina was relieved and dyspnea was improved（p.05）.but heart rate,systolic blood pressure,rate pressure product,ejection fraction,left ventricular volume and global wall motion index were not changed.conclusion trimetazidine seems to improve clinical status while can not change oxygen supply-to-demand ratio without adverse effects in patients on severe ischemic carˉdiomyopathy.

目的 曲美他嗪是一种新型的抗心肌缺血的药物，能够改善患者的运动耐量和心肌的直接保护作用同时并没有血流动力学效应。但目前对于严重缺血性心肌病患者的临床治疗价值还需要进一步观察。方法 19例（68±9）岁确诊为缺血性心肌病（左心室射血分数0%）的患者在常规治疗的基础上加用每日60mg曲美他嗪治疗3个月，随诊观察患者临床情况以及超声心动图指标的变化。结果 19例患者均可耐受在常规治疗基础上加用每日60mg曲美他嗪的治疗，随诊发现患者心绞痛发作明显减少，运动耐量明显改善。同时患者心率、收缩压、心率血压乘积、左心室射血分数、左心室容量以及整体室壁运动指数无明显改变。结论缺血性心肌病的患者在常规治疗基础上加用曲美他嗪是安全的，同时其能明显改善患者的临床状态，而这种作用并不改变心肌氧的供求比值。

Methods:A validated three dimension reconstructional echocardiographic technique for endocardial surface area was used to measure the endocardial surface area of the left ventricleand abnormal wall motionin 70 consecutive patients with first AMI.Patients undertook serial echocardiogram on the day 1,3 and 2 weeks,3 and 6 months after admission.

There was a good correlation between Ptw,AVCtw,MVOtw,PTV,PUV,UntwR and age.2.Assessment of left ventricular twisting and untwisting of DCM patients19 DCM patients(range 18-80 yr,mean age 50.52±17.52 yr,2 females) and 21 age- and sex-matched normal controls(range18-80 yr,mean age 49.05±16.94 yr,5 females) were enrolled into this study.Then DCM patients were divided into two groups:E/A＜2 group and E/A＞2 group.The routine echo showed the left ventricle dilated and EF decreased.The results show that LV rotation degree, rotation velocity at baseline and apex were irregular changeable with the cardiac cycle;the rotation direction was clockwise at the base and counterclockwise at the apex,and are combined to yield a systolic counterclockwise twisting as seen from the apex,but the rotation at the basal and apex were the same direction in some patients.
