Using transtho- racic echocardiography (TTE), we investigated the frequency of PH caused by pulmonary arteritis. Methods: This cross-sectional study included 70 patients with TA fulfilling the 1990 ACR criteria, 68 healthy controls, and 67 patients with systemic sclerosis (SSc) fulfilling the 1980 ACR criteria repre- senting the disease control group. Patients with severe left heart disease or CTE were excluded. the ESC-ERS guideline definition was considered for diagnosis of PH. Results: the mean systolic pulmonary artery pressure (SPAP) values in TA, SSc, and healthy control groups were 20.93±6.06, 31.57±12.75, and 18.88±5.39 mmHg, respectively. While the SPAP values were similar between TA and healthy groups, the SPAP values in the SSc group were significantly higher than in other groups. Based on conventional and/or magnetic resonance angiography find- ings, pulmonary arteritis was present in 4 out of 70 TA patients; however, PH was not detected in any patients with TA, including those with pulmonary arteritis. Conclusion: the TTE findings suggested that the frequency of PH was not increased in TA. However, a low frequency of pulmonary arteritis in our series might have affected our results.en10.5152/eurjrheum.2018.17052info:eu-repo/semantics/openAccessRomatolojiArticle54249253
