To determine reference values for tissue Doppler imaging (TDI) and pulsed Doppler echocardiography for left ventricular diastolic function analysis in a healthy Brazilian adult population. Observations were based on a randomly selected healthy population from the city of Vitória, Espírito Santo, Brazil. Healthy volunteers (n = 275, 61.7% women) without prior histories of cardiovascular disease underwent transthoracic echocardiography. We analyzed 175 individuals by TDI and evaluated mitral annulus E'- and A'-waves from the septum (S) and lateral wall (L) to calculate E'/A' ratios. Using pulsed Doppler echocardiography, we further analyzed the mitral E- and A-waves, E/A ratios, isovolumetric relaxation times (IRTs), and deceleration times (DTs) of 275 individuals. Pulsed Doppler mitral inflow mean values for men were as follows: E-wave: 71 ± 16 cm/sec, A-wave: 68 ± 15 cm/sec, IRT: 74.8 ± 9.2 ms, DT: 206 ± 32.3 ms, E/A ratio: 1.1 ± 0.3. Pulsed Doppler mitral inflow mean values for women were as follows: E-wave: 76 ± 17, A-wave: 69 ± 14 cm/sec, IRT: 71.2 ± 10.5 ms, DT: 197 ± 33.3 ms, E/A ratio: 1.1 ± 0.3. IRT and DT values were higher in men than in women (P = 0.04 and P = 0.007, respectively). TDI values in men were as follows: E'S: 11± 3 cm/sec, A'S: 13 ± 2 cm/sec, E'S/A'S: 0.89 ± 0.2, E'L: 14 ± 3 cm/sec, A'L: 14 ± 2 cm/sec, E'L/A'L: 1.1± 0.4. E-wave/ E'S ratio: 6.9 ± 2.2; E-wave / E'L ratio: 4.9 ± 1.7. In this study, we determined pulsed Doppler and TDI derived parameters for left ventricular diastolic function in a large sample of healthy Brazilian adults.
为确定巴西健康成年人群左心室舒张功能分析的组织多普勒成像（TDI）和脉冲多普勒超声心动图的参考值。观察对象基于从巴西圣埃斯皮里图州维多利亚市随机选取的健康人群。无心血管疾病既往史的健康志愿者（n = 275，女性占61.7%）接受经胸超声心动图检查。我们通过TDI分析了175名个体，并评估了来自室间隔（S）和侧壁（L）的二尖瓣环E'波和A'波，以计算E'/A'比值。使用脉冲多普勒超声心动图，我们进一步分析了275名个体的二尖瓣E波和A波、E/A比值、等容舒张时间（IRT）和减速时间（DT）。男性脉冲多普勒二尖瓣血流平均值如下：E波：71±16cm/秒，A波：68±15cm/秒，IRT：74.8±9.2毫秒，DT：206±32.3毫秒，E/A比值：1.1±0.3。女性脉冲多普勒二尖瓣血流平均值如下：E波：76±17，A波：69±14cm/秒，IRT：71.2±10.5毫秒，DT：197±33.3毫秒，E/A比值：1.1±0.3。男性的IRT和DT值高于女性（分别为P = 0.04和P = 0.007）。男性的TDI值如下：E'S：11±3cm/秒，A'S：13±2cm/秒，E'S/A'S：0.89±0.2，E'L：14±3cm/秒，A'L：14±2cm/秒，E'L/A'L：1.1±0.4。E波/E'S比值：6.9±2.2；E波/E'L比值：4.9±1.7。在本研究中，我们确定了大量巴西健康成年人左心室舒张功能的脉冲多普勒和TDI衍生参数。
