Resumen
ROMERO-ZERTUCHE, Diana et al. Echocardiographic analysis of pulmonary arterial systolic pressure in pulmonary hypertension. Arch. Cardiol. Méx. [online]. 2023, vol.93, n.3, pp.267-275. Epub 04-Sep-2023. ISSN 1665-1731. https://doi.org/10.24875/acm.22000124.
Introduction:
The reliability of pulmonary arterial systolic pressure by transthoracic echocardiography is limited by its variability to define pulmonary hypertension.
Objective:
To know the variability of pulmonary arterial systolic pressure estimated by echocardiography in pulmonary hypertension. Their demographic variables were obtained.
Methods:
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).
Results:
152 subjects, age 60 ± 12 years, were studied. Body mass index 27.64 ± 4.69 kg/m2. 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).
Conclusions:
Variability is wide, and agreement is substantial for pulmonary artery systolic pressure. It is recommended to estimate only as screening for pulmonary hypertension.
