目的：通过常规超声心动图测量，确定疑似心力衰竭但收缩功能保留的患者（常说有“舒张性心力衰竭"），可能有轻微的左心室收缩功能障碍，可通过一种新的左心室收缩功能测量方法-左心室收缩房室平面位移检测。设计：观察性研究。设置：直接进入超声心动图。患者：全科医生转诊的147例疑似心力衰竭患者。测量：超声心动图评估左心室收缩功能的常规测量（缩短分数、射血分数（Simpson双平面法）和“眼球”评估）和测量左心室收缩期房室平面位移。之间的21%和33%的患者与“正常”的左心室收缩功能的常规方法被发现有异常的左心室收缩房室平面displacement.Conclusions：约四分之一的患者疑似心力衰竭，但保留收缩功能的常规方法有异常的房室平面位移。这些疑似心力衰竭但常规超声心动图测量收缩功能保留的患者可能是由于轻微的收缩功能障碍而不是孤立的“舒张性心力衰竭”引起的心力衰竭。
Objectives: To determine whether patients with suspected heart failure but preserved systolic function, as determined by conventional echocardiographic measures (often said to have "diastolic heart failure), might have subtle left ventricular systolic dysfunction detectable by a new measure of left ventricular systolic function-left ventricular systolic atrioventricular plane displacement.Design: Observational study.Setting: Direct access echocardiography.Patients: 147 patients with suspected heart failure referred by general practitioners.Measurements: Echocardiographic assessment of conventional measures of left ventricular systolic function (fractional shortening, ejection fraction (by Simpson's biplane method) and "eyeball" assessment) and measurement of left ventricular systolic atrioventricular plane displacement.Results: Between 21% and 33% of patients with "normal" left ventricular systolic function by conventional methods were found to have abnormal left ventricular systolic atrioventricular plane displacement.Conclusions: Approximately one quarter of patients with suspected heart failure but preserved systolic function by conventional methods have abnormal atrioventricular plane displacement. These patients with suspected heart failure but preserved systolic function by conventional echocardiographic measures may have heart failure caused by subtle systolic dysfunction rather than isolated "diastolic heart failure".
