Factors Associated With Suggestive of Pulmonary Hypertension Measured by Echocardiography in Patients With A Mediastinal Tumor: A Single-Center Study

Ultrasound techniques are generally not used as a primary tool in the evaluation of mediastinal tumors and cysts. This study aimed to identify factors associated with pulmonary hypertension (PH) measured by transthoracic echocardiography (TTE) in patients with a mediastinal tumor. This retrospective, observational study was performed from January 2015 to December 2020. Fifty-five patients (mean age, 62 ± 13 years; 31 [56%] women) who had a mediastinal tumor and underwent TTE were included. Patients were classified as with PH or without PH. We analyzed clinical factors and echocardiographic parameters. PH was found in 21 (38%) patients. Twenty-two patients were asymptomatic, and none had symptoms associated with PH. Forty-seven (86%) patients underwent surgery, and 23 (42%) patients were diagnosed with malignant tumors. The presence of PH was not related with malignancy. Patients with PH were older than those without PH (67 ± 10 versus [vs.] 59 ± 14 years, p = 0.017). Small left ventricular (LV) systolic dimension (29.4 ± 3.6 vs. 31.6 ± 3.6 mm, p = 0.040) and dimension (4.2 ± 0.3 vs. 4.5 ± 0.3 mm, p = 0.004) and hyperdynamic LV ejection fraction (EF, 69 ± 6 vs. 65 ± 5%, p = 0.019) were associated with PH. Among them, older age, small LV dimension, and high EF were independently associated with PH.The presence of PH had no significant effect on patients’ clinical manifestation or malignancy.
