Abstract:
Hintergrund: Das Blut- und Gerinnungssystem beim Marfan-Syndrom ist bisher nur unzureichend untersucht worden. Durch die Erweiterung des Aortenbulbus kann es bei Patienten mit Marfan-Syndrom zu Veränderungen der Hämostase kommen, da diese zu veränderten Flusseigenschaften des Blutflusses führt. Die vorliegende Studie soll helfen, Ursachen und Mechanismen von Hämostasestörungen bei Marfan-Patienten besser zu verstehen, um künftig noch bessere Behandlungsmöglichkeiten anbieten zu können.

Translated abstract:
Background: Aortic root ectasia might induce hemostatic disorders in patients with Marfan syndrome (MFS) vie altered blood flow and rheology. the aim of this study was to explore the hemostasis in patients with MFS compared with healthy controls. Methods: In this corss-sectional case-control study we included patients with verified MFS (n=51) and sex- and age-matched healthy controls (n=50). Main criteria were the aortic root in echocardiography and cardiac magnetic resonance imaging (MRI), and the coagulation status. Results: When compared with healthy controls, patients with MFS showed significantly increased diameters of the aortic roots (P<0.001) and aortic Z-Scores (P<0.001), considerably higher values of Multiplate tests (P<0.001) and PFA-100 tests (P<0.05), PTT (P<0.05) and D-dimers (p<0.001). In MFS von Willebrand factor (VWF) activity (P<0.05) and antigen(P<0.05) and factor VIII activity (P<0.05) were reduced. Significant positive correlations were found between aortic diameters and D-dimers (all p<0.05), as well as PFA Col/ADP (P<0.01) in MFS patients. Factor VIII activity correlated significantly negatively with the diameter of the aortic root in MFS (P<0.05). Conclusions: In conclusion, our study reveals hemostatic deviations in patients with MFS. Further studies are necessary to understand the causal relationship and the exact pathomechanism.
