背景
高二尖瓣流入早期（E）速度与组织多普勒E'比（E/E'）和E与舒张晚期充盈速度比（E/A）用于评价左心室（LV）舒张功能和充盈压，但联合评估的有用性E/E'和E/A尚未完全了解。方法：回顾性分析1,266例经超声心动图检查的患者的心功能。根据E/E'（低E/E'<15，高E/E '≥ 15）和E/A（低E/A≤0.8，高E/A>0.8）值对患者进行分组。结果如下：高E/E'伴高和低E/A组与低E/E'伴高和低E/A组相比，显示出较低的LV射血分数和较高的LV质量指数。高E/E'高、低E/A组的E'速度和左房容积指数均较低E/E'高、低E/A组低，但高E/E'低E/A组的左房容积指数和肺静脉收缩期与舒张期峰值速度比均较高E/E'高E/A组高。高E/E'低E/A组的三尖瓣反流压差低于高E/E'高E/A组。结论：即使在高E/E '的情况下，低E/A也表明左室充盈压较低，液体潴留得到控制。
BACKGROUND
High mitral inflow early (E) velocity to tissue Doppler E' ratio (E/E') and an E to late diastolic filling velocity ratio (E/A) are used to evaluate left ventricular (LV) diastolic function and filling pressure, but the usefulness of combined assessment of E/E' and E/A is not fully understood. Methods: We retrospectively analyzed 1,266 patients who underwent echocardiography to assess cardiac function. Patients were grouped based on the values of E/E' (low E/E'<15, high E/E'≥15) and E/A (low E/A≤0.8, high E/A>0.8). Results: High E/E' with both high and low E/A groups showed lower LV ejection fraction and higher LV mass index compared to low E/E' with both high and low E/A groups. High E/E' with both high and low E/A groups showed slower E' velocity and larger left atrial volume index compared to low E/E' with both high and low E/A groups, but high E/E' with low E/A group exhibited smaller left atrial volume index and higher pulmonary venous systolic to diastolic peak velocity ratio compared to high E/E' with high E/A group. Moreover, high E/E' with low E/A group displayed lower tricuspid regurgitant pressure gradient than the high E/E' with high E/A group. Conclusion: Even in the situation of high E/E', low E/A condition indicated lower LV filling pressure and controlled fluid retention.
