Abstract:
Objective:To investigate the clinical-epidemiological characteristics of connective tissue diseases (CTD) complicated with pulmonary hypertension in Shanxi province from 2018 to 2021.Methods:This was a cross-sectional study. Data of CTD patients with pulmonary hypertension from 2018 to 2021 were collected from the Shanxi Provincial Health Statistics Direct Reporting System based on inpatient medical records. The demographic and clinical data of patients with different CTD types were analyzed.Results:A total of 1 697 CTD patients with pulmonary hypertension were included, among whom there were 451 cases (26.58%) of Sj?gren′s syndrome, 392 cases (23.10%) of systemic lupus erythematosus, 289 cases(17.03%) of systemic sclerosis, 109 cases (6.42%) of mixed CTD, 69 cases (4.07%) of Takayasu arteritis, and 387 cases (22.80%) of other CTD. The majority of patients were female (1 410 (83.09%)), and 783 cases (46.14%) were aged between 41 and 65 years, and 6 cases (0.35%) were performed right heart catheterization. The prevalence of CTD with pulmonary hypertension increased from 0.06/10 4 in 2018 to 0.20/10 4 in 2021. There were significant differences in the severity of pulmonary hypertension, New York Heart Association (NYHA) functional class, length of hospital stay, medical costs, and clinical outcomes among patients with different CTD subtypes (all P<0.001). Patients with systemic sclerosis had the highest proportion of NYHA functional class Ⅲ/Ⅳ(65.1%(188/289)), the longest length of hospital stays (13 (9, 18) days), the highest average medical costs (13 622.67 (8 636.38, 20 597.75) ￥(RMB)), and the lowest rate of improvement and discharge (51.90%(150/289)). Conclusions:Between 2018 and 2021, Shanxi province, where CTD is more common in Sj?gren′s syndrome, has a high proportion of women, a high proportion of people aged 41-65 years, and a low prevalence of right ventricular catheterization in patients with CTD complicated with pulmonary hypertension. The prevalence of CTD complicated with pulmonary hypertension shows a rising trend in Shanxi province from 2018 to 2021, while patients with systemic sclerosis exhibit the most severe cardiac impairment and poorer clinical outcomes compared to other subtypes.
