诊断试验:

Diagnostic Tests:

金标准或参考标准(即可准确诊断某疾病的单项方法或多项联合方法,在本研究中用于诊断是否有该病的临床参考标准):

金标准为右心导管漂浮术,由于注册单位未具有足够样本的手术,本实验采用经胸超声心动图诊断肺动脉高压标准作为参考标准。根据《中国肺动脉高压诊断与治疗指南(2021版)》,经胸超声心动图诊断肺动脉高压标准为三尖瓣流速在2.9m/s及以上,预估肺动脉收缩压(Pulmonary artery systolic pressure,PAP)大于40mmHg。

Gold Standard or Reference Standard (The clinical reference standards required to establish the presence or absence of the target condition in the tested population in present study):

The gold standard was right cardiac catheter flotation. As the registered unit did not have enough samples for the operation, transthoracic echocardiography was used as the reference standard for diagnosing pulmonary hypertension in this study. According to the Chinese Guidelines for the Diagnosis and Treatment of Pulmonary Hypertension (2021 edition), the criteria for the diagnosis of pulmonary hypertension by transthoracic echocardiography are tricuspid valve flow rate of 2.9m/s or above, and the estimated Pulmonary artery systolic pressure (PAP) is greater than 40mmHg.

指标试验(即本研究的待评估诊断试验,无论为方法、生物标志物或设备,均请列出名称):

EIT测量和图像采集是通过EC-100(PRO)平台进行的,这是一个16电极EIT数据采集系统,能够以每秒40帧的频率成像。所有样本阻抗数据与PPG数据按照时间序列对齐。可见PPG在每一心动周期内均存在两个波峰,以周期内较低波峰对应时间点作为参考帧位置(周期起点),较高波峰对应时间点作为前景帧)位置(周期终点)。通过GREIT 算法,基于EIDORS V3.10 软件平台。首先,对各心动周期内阻抗数据进行EIT图像重构,根据胸腔解剖结构与阻抗分布状况划定肺灌注对应感兴趣区。之后,计算每一心动周期ROI各像素点相对变化比例,求取平均值ΔZq,并对屏息段所有心动周期进行叠加平均,以消除周期间误差。

Index test:

The EIT (Electrical Impedance Tomography) measurements and image acquisitions were performed using the EC-100 (PRO) platform, a 16-electrode EIT data acquisition system capable of imaging at a rate of 40 frames per second. All sample impedance data and PPG (Photoplethysmography) data were aligned in a time series. It is observed that PPG shows two peaks within each cardiac cycle. The time point corresponding to the lower peak within the cycle is used as the reference frame position (start of the cycle), and the time point corresponding to the higher peak is used as the foreground frame position (end of the cycle). Using the GREIT algorithm, based on the EIDORS V3.10 software platform, the process begins with the reconstruction of EIT images for each cardiac cycle, identifying the region of interest (ROI) corresponding to lung perfusion based on thoracic anatomy and impedance distribution. Subsequently, the relative change ratio of each pixel within the ROI for each cardiac cycle is calculated to find the average value ΔZq. This process is repeated for all cardiac cycles during the breath-hold phase to average out inter-cycle variations.
