Abstract

The aim of this study was to investigate arterial wall stiffness and its relationship with right ventricle systolic function (RVSF) in patients with interstitial lung disease. Methods. Fifty patients with chronic hypersensitivity pneumonitis (HP) and 26 patients with idiopathic pulmonary fibrosis (IPF) were included. Spirometry,  body plethysmography  were performed,  lung diffusion capacity for carbon monoxide (DLCO), blood gases and arterial wall stiffness were measured. High resolution computed  tomography (HRCT) of the chest was assessed using Kazerooni  scale. Results. The aortic pulse wave velocity (PWV, m/s) was increased in 26 (52%) patients with HP and in 14 patients with IPF. Correlation  analysis showed statistically significant  association  between  PWVАo  and DLCO  (p < 0.05),  partial  oxygen pressure in the arterial  blood (PaO2)  (p < 0.05),  pulmonary  fibrosis (p = 0.001), and the extension of ground glass opacities (p < 0.05). Tricuspid annual plane systolic excursion (TAPSE),  right ventricular myocardial performance  index (MPI)  and tricuspid annular systolic velocity (S’) were significantly related to PWVАo, ambulatory arterial stiffness index (AASI) and augmentation index (AIx) (p < 0.05). Conclusion. Increased arterial stiffness was often found in patients with HP and IPF. The increased arterial stiffness is associated with hypoxemia, pulmonary fibrosis and decreased lung diffusion capacity. The arterial stiffness is also related to the right ventricular systolic dysfunction.
