Systemic sclerosis patients with and without pulmonary arterial hypertension: a nailfold capillaroscopy study

Our results underline the relevance of early microvascular assessment in patients at risk of developing a severe complication such as PAH that can amplify the systemic microvascular impairment in SSc. More severe NVC abnormalities should lead to strict cardiopulmonary surveillance and a complete NVC study is indicated.
