The reliability of pulmonary arterial systolic pressure by transthoracic echocardiography is limited by its variability to define pulmonary hypertension.
To know the variability of pulmonary arterial systolic pressure estimated by echocardiography in pulmonary hypertension. Their demographic variables were obtained.
From 2016-2020 subjects with pulmonary hypertension were recruited, with pulmonary artery systolic pressure estimated by transthoracic echocardiography and by right heart catheterization. Data were analyzed using the Bland-Altman descriptive statistic and the intraclass correlation coefficient (95% confidence interval).
152 subjects, age 60 ± 12 years, were studied. Body mass index 27.64 ± 4.69 kg/m. The pulmonary artery systolic pressure estimated by transthoracic echocardiography 58.99 ± 18.62 vs. cardiac catheterization 55.43 ± 16.79 mmHg. Mean difference (bias) -3.6 (29.1, -36.2) and intraclass correlation coefficient 0.717 (0.610, 0.794).
Variability is wide, and agreement is substantial for pulmonary artery systolic pressure. It is recommended to estimate only as screening for pulmonary hypertension.
经胸超声心动图测量的肺动脉收缩压的可靠性受到其变异性的限制,无法准确定义肺动脉高压。
了解超声心动图评估肺动脉高压时肺动脉收缩压的变异性。获取其人口统计学变量。
从 2016 年至 2020 年,招募了肺动脉高压患者,通过经胸超声心动图和右心导管术评估肺动脉收缩压。采用 Bland-Altman 描述性统计和组内相关系数(95%置信区间)分析数据。
研究纳入了 152 名年龄 60±12 岁的患者。体重指数 27.64±4.69kg/m。经胸超声心动图估计的肺动脉收缩压为 58.99±18.62mmHg,与右心导管术的 55.43±16.79mmHg 相比。平均差值(偏差)为-3.6(29.1,-36.2),组内相关系数为 0.717(0.610,0.794)。
肺动脉收缩压的变异性较宽,一致性较好。建议仅将其作为肺动脉高压的筛查手段。
