The objective of this study was to assess transthoracic echocardiography (TTE) parameters in pregnancy by race and ethnicity.
We performed a retrospective cohort study of pregnant individuals without cardiovascular disease who underwent a perinatal TTE between October 2017 and May 2022. Demographics and echocardiographic parameters were compared by race/ethnicity. Multivariate regression analysis was performed for TTE parameters after adjusting for age and hypertension.
During the study period, 369 individuals had TTEs with a mean age of 31.8 ± 6.0 years old. Subjects were 55.3% White, 24.7% Hispanic, 14.1% Black, and 6.0% Asian. TTE parameters of left ventricular (LV) ejection fraction and LV mass index differed by race/ethnicity, though no difference was seen in cardiac geometry.
The differences in TTE parameters may not be clinically significant as most values fall within normal clinical ranges. Further prospective studies are needed to better evaluate cardiac outcomes by differences in echocardiographic parameters in pregnancy.
本研究的目的是按种族和民族评估孕期经胸超声心动图（TTE）参数。
我们对2017年10月至2022年5月期间接受围产期TTE检查的无心血管疾病孕妇进行了一项回顾性队列研究。按种族/民族比较人口统计学和超声心动图参数。在调整年龄和高血压因素后，对TTE参数进行多变量回归分析。
在研究期间，369名个体接受了TTE检查，平均年龄为31.8±6.0岁。受试者中55.3%为白人，24.7%为西班牙裔，14.1%为黑人，6.0%为亚洲人。左心室（LV）射血分数和LV质量指数的TTE参数因种族/民族而异，不过心脏几何形状未见差异。
由于大多数值落在正常临床范围内，TTE参数的差异可能无临床意义。需要进一步的前瞻性研究，以通过孕期超声心动图参数的差异更好地评估心脏结局。
