测量左心室（LV）充盈压可用于各种心血管疾病的决策和预后预测。有创心导管插入术是LV充盈压测量的金标准，但存在并发症风险，并且与超声心动图无创LV充盈压估计相比，其临床结局预测值相似。已经提出了多种超声心动图测量方法来估计LV充盈压。最常用于此目的的方法是二尖瓣早期流入速度与二尖瓣环舒张早期速度之间的比值（E/e '），这已成为舒张评估指南的核心。本文将讨论使用E/e'比率预测左室充盈压及其潜在的缺陷。
Measurement of left ventricular (LV) filling pressure is useful in decision making and prediction of outcomes in various cardiovascular diseases. Invasive cardiac catheterization has been the gold standard in LV filling pressure measurement, but carries the risk of complications and has a similar predictive value for clinical outcomes compared with non-invasive LV filling pressure estimation by echocardiography. A variety of echocardiographic measurement methods have been suggested to estimate LV filling pressure. The most frequently used method for this purpose is the ratio between early mitral inflow velocity and mitral annular early diastolic velocity (E/e'), which has become central in the guidelines for diastolic evaluation. This review will discuss the use the E/e' ratio in prediction of LV filling pressure and its potential pitfalls.
