An observational study in Pulmonary Embolism, sponsored by Centre Hospitalier Universitaire de Saint Etienne. Completed at 2 sites in France. Open to participants aged 18 Years to 75 Years. Per ClinicalTrials.gov, last updated 2013-11-07.
Sponsored by Centre Hospitalier Universitaire de Saint Etienne · Observational
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.
753 studies on the registry are indexed under Pulmonary Embolism; 157 are open to participants now.
This study's enrollment of 50 is below the median of 370 across 332 observational studies indexed under Pulmonary Embolism.

difference of pulmonary capillary blood volume (Vc) from J0 to 6 months
Time frame: from the starting of the anticoagulant therapy to 6 months after
