Description for medicine or protocol of treatment in detail:

 

纳入标准:

1. X 射线检查对象的年龄在 18 岁以上 90 岁以下 2.以 DICOM 格式提取全分辨率的胸部 X 光片 3. X 光片和超声心动图在 12 个月内完成 4. X 射线图像捕捉到心脏。 5. 仅包括后正前方 X 光片 6.具有所有相关连续三个测量值的超声心动图

Inclusion criteria

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):

①超声心动图诊断心肌肥厚的金标准:男性受试者 IVSd值 > 1.5 厘米 或者 LVPWd值 > 1.5 厘米 ,女性受试者IVSd值 > 1.4 厘米 或者 LVPWd值 > 1.4 厘米。 ②超声心动图诊断左心室舒张功能障碍的金标准:受试者(E/A值 ≤ 0.8 或者 ≥2 )并且 E’值≤50 厘米 / 秒。 ③超声心动图诊断右心室功能障碍的金标准:受试者FAC值 < 35% 或者 TAPSE值 > 15 mm或者 MPI值 > 4.3。

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):

In echocardiography, male subjects with an interventricular septal thickness at end-diastole (IVSd) value > 1.5 cm or a left ventricular posterior wall thickness at end-diastole (LVPWd) value > 1.5 cm, and female subjects with an IVSd value > 1.4 cm or an LVPWd value > 1.4 cm were labeled as having myocardial hypertrophy. Subjects with an early to late diastolic filling velocity ratio (E/A value) <= 0.8 or >= 2 and an early diastolic mitral annular velocity (E’ value) <= 50 cm/s were labeled as having left ventricular diastolic dysfunction. Subjects with a fractional area change of the basal segment (FAC) < 35% or a tricuspid annular plane systolic excursion (TAPSE) > 15 mm or a myocardial performance index (MPI) > 4.3 were labeled as having right ventricular dysfunction.

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):

深度学习模型诊断左右心室功能障碍的概率

Index test:

The probability of diagnosing left ventricular diastolic dysfunction and right ventricular dysfunction by the deep learning model.

例数:

Sample size:

2000

Target condition (The target condition is a particular disease or disease stage that the index test will be intended to identify. Please specify the characteristics in detail; the population should has a complete spectrum and good representative):

例数:

Sample size:

8000

Population with condition difficult to distinguish from the target condition, the normal population in a case-control study design should be avoid:
