Summary

The purpose of this monocentric, preliminary study is to assess the evolution of pulmonary capillary blood volume (Vc), measured by the double diffusion nitric oxide/carbon monoxide (NO/CO) method (Guenard et al.; Respir Physiol 1987), from the starting of the anticoagulant therapy to 6 months after, and to search correlations with the evolution of clinical (dyspnea and results of the 6 minutes walking test), biological (BNP; Troponin), echocardiographic (right ventricular dysfunction, pulmonary arterial pressure) and ventilation/perfusion lung scan data.

Conditions

OTHER

diffusion NO/CO method

pulmonary capillary blood volume (Vc), measured by the double diffusion NO/CO method: this method is to inhale during a deep inspiration with a mixture of helium (8-10%), CO (2000 ppm) and NO (20-40 ppm), the O2 (21%)
