二尖瓣环舒张早期血流速度(E‘)与二尖瓣环血流速度(E’)之比可作为评价左心室充盈压的无创性指标。我们评估了174例正常人和86例高血压和左心室肥厚患者，以评估年龄、性别和左心室肥厚对E‘和E/E’的影响。年龄似乎是E‘和E/E’的最强决定因素，提示在正常患者和有左室肥厚的患者中，应考虑年龄相关的临界值。(C)2005年，由Excerpta Medica Inc.
The ratio of the transmitral early peak velocity (E) evaluated by conventional Doppler imaging over early diastolic mitral annulus velocity (E') evaluated by tissue Doppler imaging has been proposed as a noninvasive marker for left ventricular filling pressure. We evaluated 174 normal patients and 86 patients with hypertension and LV hypertrophy to assess the effects of age, gender, and left ventricular hypertrophy on E' and E/E'. Age appeared to be-the strongest determinant of E' and E/E', suggesting that in normal patients and in those with left ventricular hypertrophy, age-dependent cut-off values should be considered.
