Assessment of systemic and pulmonary arterial remodelling in women with systemic sclerosis.

Objectives: Systemic sclerosis (SSc) leads to pulmonary circulation dysfunctionand there are some indications of systemic circulation impairment. We evaluated the influence of SSc on the elastic properties of large systemic arterial walls and potential correlations between systemic and pulmonary circulation involvement.Method: We examined 75 consecutive women (mean age 53.13 ± 10.1 years) with confirmed SSc [mean disease duration (DD) 7.1 ± 9.1 years] and 21 age-matched female volunteers (mean age 52.6 ± 8.3 years, ns). Pulse wave velocity (PWV) and transthoracic echocardiography were performed. SSc patients were divided into two groups according to the median of DD: ≤ 3 years (39 patients) and > 3 years (36 patients).Results: Patients with DD > 3 years had higher PWV than those with DD ≤ 3 years and controls (log PWV: 2.23 ± 0.23 vs. 2.13 ± 0.16 and vs. 2.11 ± 0.16 m/s; p = 0.028 and 0.029, respectively). In addition, echocardiographic indices showed impaired right ventricular (RV) function in the patien...
