目前认为临床上约有三分之一的充血性心力衰竭患者是由于左室舒张功能衰竭所致。而且在没有出现明确的心力衰竭症状之前,左心室的舒张功能已经出现障碍。我们对临床上诊断为左室舒张功能不全所致的充血性心力衰竭患者进行二维超声心动图测定其舒张末期左室内经(Dd),室间隔厚度(IVSd)、左室后壁厚度(LVPwd),并计算R(radigo)、Th(Thickness)比值,以期探讨左室舒张不全心衰患者的R/Th比值的变化。 1 材料和方法 1.1 心衰组 临床上明确诊断为左室舒张功能不全所致心力衰竭患者24例。男性16例,女性8例。年龄:62±14岁。其中冠心病6例,高血压性心脏病14例,肥厚型心肌病4例。
At present, about one-third of patients with congestive heart failure clinically due to left ventricular diastolic dysfunction. And in the absence of a clear symptom of heart failure, left ventricular diastolic dysfunction has emerged obstacles. We performed a two-dimensional echocardiographic analysis of left ventricular end diastolic dimension (Dd), interventricular septum thickness (IVSd), left ventricular posterior wall thickness (LVPwd), left ventricular diastolic dimension (LVPwd) in patients with congestive heart failure due to clinically diagnosed left ventricular diastolic dysfunction ), And R (radigo), Th (Thickness) ratio was calculated in order to investigate the changes of R / Th ratio in patients with left ventricular dysfunction. 1 Materials and Methods 1.1 Heart failure group clinically diagnosed as 24 cases of heart failure caused by left ventricular diastolic dysfunction. 16 males and 8 females. Age: 62 ± 14 years old. Including coronary heart disease in 6 cases, 14 cases of hypertensive heart disease, hypertrophic cardiomyopathy in 4 cases.
