Purpose: Ross syndrome (RS) is characterized by selective involvement of post-ganglionic skin sympathetic nerve fibres. We report a follow-up study in 4 patients to clarify whether in RS autonomic dysfunction spreads affecting also cardiovascular system.
Methods: The patients underwent cardiovascular reflexes (CVR) and microneurography recording of muscle sympathetic nerve activity (MSNA) for a follow-up mean period of 5years.
Results: CVR and MSNA were normal at baseline and unchanged over the follow-up.
Conclusions: Cardiovascular autonomic system is spared in RS differently from skin autonomic activity dysfunction which progress over time. However, before drawing any definite conclusion, a large cohort of patients needs to be studied.
