Does continuous positive airway pressure normalize cardiac autonomic and hemodynamic responses to a laboratory stressor in apneic patients?
These results indicate that CPAP normalizes contractility, increases cardiac vagal tone, and changes hemodynamic regulation from being resistance dominated to being cardiac dominated. Thus, after 1 week of treatment with CPAP, many of the indicators of poor cardiac functioning in apnea patients are improved.
Arterial pathology in vEDS individuals is related to the underlying COL3A1 mutation type. The arterial pathology in individuals with HI mutations occurs at later ages with a higher incidence of aortic disease compared with other COL3A1 mutation types. Molecular diagnosis is recommended because diagnosis confirmation, appropriate surveillance, and prophylactic interventions in an elective setting improve surgical outcomes.
