- W1818083945 abstract "Background: Transtchoracic echocardiography (TTE) is accepted as screening tool for pulmonary hypertension (PAH), nerveless it is rarely performed in COPD patients due to possible difficulties caused by hyperinflated lungs.Aims and objectives: The aim of our study was to find out whether it would be possible to predict if TTE is capable to assess pulmonary artery pressure (PAP) in patients with COPD exacerbation.Methods: 40 consecutive patients with COPD exacerbation were enrolled. TTE directed for diagnosis of PAP, pulmonary function tests, blood gases, six minute walking test and BORG scale were performed at baseline and after successful treatment.Results: It was possible to perform TTE in 17 (42,5%) subjects on admition and in 26 (65%) at discharge. PAH was present in 88,2% pre-treatment, and in 80,8% post-treatment (PAP mean≥25 mmHg), and in 35,3% pre-treatment and in 52,9% post-treatment (RVSP>35 mmHg). It was possible to measure PAPmean in 94,1% patients pre-treatment, and in 96,2% post-treatment, whereas it was possible to measure RVSP in 58,8% patients pre-treatment before, and 65,4% post-treatment. Simple as well as multivariable analysis did not find predictive value (p>0,05) of the following parameters: FEV1, FVC, IC, RV%TLC, TLC, ITGV, TLCO/VA, pO2, pCO2, 6MWT distance, BORG scale, COPD stage (GOLD), BMI, pack-years, sputum purulence to prognose possibility of obtaining accurate TTE results.Conclusions: TTE may be used as noninvasive tool in assessment of PAPmean and in much smaller extent in assessment of RVSP in patients with COPD exacerbation, but it still seems impossible to predict in which patients it would be possible to perform accurate TTE." @default.
