This study aimed to investigate the relationship between echocardiography results and lung ultrasound score (LUS) in coronavirus disease 2019 (COVID-19) pneumonia patients and evaluate the impact of the combined application of these techniques in the evaluation of COVID-19 pneumonia. Hospitalized COVID-19 pneumonia patients who underwent daily lung ultrasound and echocardiography were included in this study. Patients with tricuspid regurgitation within three days of admission were enrolled. Moreover, the correlation and differences between their pulmonary artery pressure (PAP) and LUS on days 3, 8, and 13 were analyzed. The inner diameter of the pulmonary artery root as well as the size of the atria and ventricles were also considered. The PAP on days 3, 8, and 13 of hospitalization was positively correlated with the LUS (r = 0.448, p = 0.003; r = 0.738, p < 0.001; r = 0.325, p = 0.036, respectively). On day 8, the values of both PAP and LUS were higher than on days 3 and 13 (p < 0.01). Similarly, PAP and LUS were significantly increased in 92.9% (39/42) and 90.5% (38/42) of patients, respectively, and at least one of these two values was positive in 97.6% (41/42) of cases. The inner diameters of the right atrium, right ventricle, and pulmonary artery also differed significantly from their corresponding values on days 3 and 13 (p < 0.05). PAP is positively correlated with LUS in COVID-19 pneumonia. The two values could be combined for a more precise assessment of disease progression and recovery status.

超声心动图联合肺部超声评估COVID-19肺炎价值的初步研究

本研究旨在调查 2019 年冠状病毒病 (COVID-19) 肺炎患者的超声心动图结果与肺部超声评分 (LUS) 之间的关系，并评估这些技术联合应用在 COVID-19 肺炎评估中的影响。本研究纳入了接受每日肺部超声和超声心动图检查的住院 COVID-19 肺炎患者。入院三天内出现三尖瓣关闭不全的患者入组。此外，分析了它们在第3、8和13天的肺动脉压（PAP）和LUS之间的相关性和差异。还考虑了肺动脉根部的内径以及心房和心室的大小。住院第 3、8 和 13 天的 PAP 与 LUS 呈正相关（r = 0.448，p = 0.003；r = 0.738，p < 0.001；r = 0.325，p = 0.036，分别）。第 8 天，PAP 和 LUS 的值均高于第 3 天和第 13 天（p < 0.01）。同样，PAP 和 LUS 分别在 92.9% (39/42) 和 90.5% (38/42) 的患者中显着增加，并且这两个值中的至少一个在 97.6% (41/42) 的病例中为阳性。右心房、右心室和肺动脉的内径与第 3 天和第 13 天的相应值也有显着差异（p < 0.05）。PAP 与 COVID-19 肺炎中的 LUS 呈正相关。可以将这两个值结合起来，以更精确地评​​估疾病进展和恢复状态。PAP 和 LUS 分别在 92.9% (39/42) 和 90.5% (38/42) 的患者中显着增加，并且这两个值中的至少一个在 97.6% (41/42) 的病例中呈阳性。右心房、右心室和肺动脉的内径与第 3 天和第 13 天的相应值也有显着差异（p < 0.05）。PAP 与 COVID-19 肺炎中的 LUS 呈正相关。可以将这两个值结合起来，以更精确地评​​估疾病进展和恢复状态。PAP 和 LUS 分别在 92.9% (39/42) 和 90.5% (38/42) 的患者中显着增加，并且这两个值中的至少一个在 97.6% (41/42) 的病例中呈阳性。右心房、右心室和肺动脉的内径与第 3 天和第 13 天的相应值也有显着差异（p < 0.05）。PAP 与 COVID-19 肺炎中的 LUS 呈正相关。可以将这两个值结合起来，以更精确地评​​估疾病进展和恢复状态。PAP 与 COVID-19 肺炎中的 LUS 呈正相关。可以将这两个值结合起来，以更精确地评​​估疾病进展和恢复状态。PAP 与 COVID-19 肺炎中的 LUS 呈正相关。可以将这两个值结合起来，以更精确地评​​估疾病进展和恢复状态。
