In recent years, the significant limitations associated with the use of vitamin K antagonists (VKA) have encouraged the development of new agents. Based upon the central roles played by the serine proteases thrombin and Factor Xa in the blood coagulation cascade, direct thrombin inhibitors and direct Factor Xa inhibitors have been developed. These agents,(More)
BACKGROUND Toxoplasmosis is one of the most common human zoonosis, and is generally benign in most of the individuals. Pulmonary involvement is common in immunocompromised subjects, but very rare in immunocompetents and there are scarce reports of tomographic findings in the literature. The aim of the study is to describe three immunocompetent patients(More)
OBJECTIVE To evaluate the role of right heart catheterization in the diagnosis of pulmonary arterial hypertension (PAH).

BACKGROUND Pulmonary arterial hypertension is a progressive disease that is characterized by dyspnea and exercise intolerance. Impairment in skeletal muscle has recently been described in PAH, although the degree to which this impairment is solely determined by the hemodynamic profile remains uncertain. The aim of this study was to verify the association of(More)
BACKGROUND Schistosomiasis associated pulmonary arterial hypertension (Sch-PAH) might represent the most prevalent form of PAH worldwide. In Sch-PAH, the presence of aneurismal dilation of the pulmonary artery has been described, although it is still a matter of debate whether on average the pulmonary artery is more enlarged in Sc-PAH than IPAH.
