目的:探讨右心房容积、心肌应变、应变率在评价左心室射血分数正常的原发性高血压患者右心房功能中的应用价值。方法:回顾性收集2018年3月至2020年5月南京医科大学附属常州第二人民医院就诊的左心室射血分数正常的原发性高血压患者126例，其中男66例，女60例，年龄18~83（48±15）岁。根据左心室心肌质量指数将其分为左心室壁无增厚组66例、左心室壁增厚组60例。选取体检正常者83名作为对照组，其中男42名，女41名，年龄14~88（48±16）岁。运用右心房容积法分别测量受试者的右心房最大排空分数、右心房被动收缩排空分数和右心房主动收缩排空分数；二维斑点追踪成像技术测量右心房心肌应变（存储功能应变、通道功能应变和泵功能应变）和应变率（存储功能应变率、通道功能应变率和泵功能应变率），其中右心房存储功能指标为最大排空分数、存储功能应变和存储功能应变率，右心房通道功能指标为被动收缩排空分数、通道功能应变和通道功能应变率，右心房泵功能指标为主动收缩排空分数、泵功能应变和泵功能应变率。分别比较原发性高血压组与对照组两组间，以及原发性高血压左心室壁无增厚组、原发性高血压左心室壁增厚组及对照组三组间存储功能、通道功能及泵功能指标的差异。结果:原发性高血压组主动收缩排空分数低于对照组（40.1%±10.5%比45.4%±11.1%，n P=0.001）；原发性高血压左心室无增厚组、左心室壁增厚组及对照组三组间的被动收缩排空分数及主动收缩排空分数值差异均具有统计学意义（被动收缩排空分数：40.2%±9.3%比36.4%±10.7%比36.5%±9.4%，n P=0.038；主动收缩排空分数：39.8%±10.6%比40.4%±10.4%比45.4%±11.1%，n P=0.002）。原发性高血压组的存储功能应变、通道功能应变、泵功能应变、存储功能应变率、通道功能应变率和泵功能应变率与对照组比较，差异均具有统计学意义［存储功能应变：34.8%±13.7%比45.0%±13.3%，通道功能应变：18.3%±9.4%比26.5%±9.6%，泵功能应变：16.4%±7.3%比18.6%±7.1%，存储功能应变率：（1.6±0.6）/s比（2.0±0.6）/s，通道功能应变率：（-1.2±0.5）/s比（-1.6±0.6）/s，泵功能应变率：（-1.7±0.6）/s比（-2.3±0.6）/s；均n P原发性高血压左心室壁无增厚组>原发性高血压左心室壁增厚组（均n P<0.001）。n 结论:同时运用右心房容积、右心房应变、应变率可以全面评估原发性高血压患者右心房存储、通道及泵功能的受损，且原发性高血压左心室壁增厚组的右心房通道功能受损更为明显。“,”Objective:To explore the application values of right atrial (RA) volume, myocardial strain and strain rate in evaluating right atrial functions in patients with essential hypertension (EHT) with normal left ventricular ejection fraction (LVEF).Methods:We retrospectively collected a total of 126 EHT patients with normal LVEF, including 66 males and 60 females, age from 18 to 83(48±15) years from the Affiliated Changzhou No.2 People′s Hospital with Nanjing Medical University from March, 2018 to May, 2020. According to the left ventricular mass index, those patients were divided into without left ventricle hypertrophy (LVH) group (n n=66) and LVH group (n n=60), and 83 healthy volunteers were enrolled as control group, which including 42 males and 41 females, age from 14 to 88 (48±16) years. The total, passive and active RA emptying fraction (total RAEF, passive RAEF and active RAEF) were measured by using RA volumes method. The RA strain (S-reservoir, S-conduit, S-booster pump) and the strain rate (SR-reservoir, SR-conduit, SR-booster pump) were measured by two-dimensional speckle tracking echocardiography. Total RAEF, S-reservoir, and Sr-reservoir represented the reservoir function, while passive RAEF, S-conduit, and Sr-conduit represented the conduit function, and active RAEF, S-booster pump and Sr-booster pump represented the booster pump function, respectively. Than the values between the EHT patients and normal subjects, and the values among the EHT patients without LVH, EHT patients without LVH and normal subjects were compared.n Results:The value of active RAEF was significantly lower in EHT patient than normal controls (40.1%±10.5% vs 45.4%±11.1%,n P=0.001). There were significant differences among EHT patients without LVH, EHT patients with LVH and normal subjects in passive RAEF and active RAEF (passive RAEF: 40.2%±9.3% vs 36.4%±10.7% vs 36.5%±9.4%, n P=0.038, active RAEF: 39.8%±10.6% vs 40.4%±10.4% vs 45.4%±11.1%, n P=0.002). There were significant differences in S-reservoir, S-conduit, S-booster pump, SR-reservoir, SR-conduit and SR-booster pump between EHT patients and normal subjects [S-reservoir: 34.8%±13.7% vs 45.0%±13.3%, S-conduit: 18.3%±9.4% vs 26.5%±9.6%, S-booster pump: 16.4%±7.3% vs 18.6%±7.1%, SR-reservoir: (1.6±0.6)/s vs (2.0±0.6)/s, SR-conduit: (-1.2±0.5)/s vs (-1.6±0.6)/s, SR-booster pump: (-1.7±0.6)/s vs (-2.3±0.6)/s; all n P<0.05]. The trend tests showed normal controls achieved the largest the absolute values of S-reservoir, S-conduit, SR-reservoir, SR-conduit, SR-booster pump, followed by EHT patients without LVH and EHT patients with LVH(alln P<0.001).n Conclusions:Using RA volume, myocardial strain and strain rate can detect the RA impaired reservoir, conduit, and the booster pump functions in EHT patients with normal LVEF, and the RA functions were damaged more significantly in EHT patients with LVH.
