Non-invasive diagnostic and functional evaluation of cardiac and pulmonary involvement in systemic sclerosis.

Abstract

Taken together these results indicate that a pulmonary involvement occurs both in limited and in diffuse cutaneous SSc patients and develops, in 83% of the cases, without any regional lung perfusion abnormality. Furthermore, cardiac involvement is detected in 65% of the cases as a consequence of a range of noxious events including myocardial ischemia, fibrosis and pressure overload which may result in ventricular dysfunction and arrhythmias. Lung perfusion MRI should be considered as a complementary diagnostic method for the functional evaluation of these symptoms in systemic sclerosis.
