Abstract
Background
Idiopathic hypereosinophilic syndrome is characterized by a persistent eosinophil blood count of >1.5 × 109 cells/l and organ damage, independent of the primary and secondary causes of eosinophilia. The purpose of the present study was to assess the three-dimensional speckle tracking echocardiography-derived right atrial volumetric and functional properties between hypereosinophilic syndrome patients and matched controls.
Methods
A total of 11 patients with idiopathic hypereosinophilic syndrome and 22 age- and gender-matched healthy controls were enrolled in the study. Three-dimensional speckle tracking echocardiography was used for calculation of right atrial volumes, volume-based functional properties, and strain parameters.
Results
Significantly increased right atrial maximum (68.7 ± 33.1 ml vs. 40.3 ± 12.1 ml, respectively; p = 0.001) and minimum volumes (48.3 ± 31.0 ml vs. 28.3 ± 9.4 ml, respectively; p = 0.009), as well as right atrial volume before atrial contraction (58.6 ± 27.3 ml vs. 34.5 ± 11.8 ml, respectively; p = 0.001), were found in hypereosinophilic syndrome patients compared with controls. Total and passive right atrial stroke volumes proved to be significantly increased in hypereosinophilic syndrome patients. However, global and mean segmental strain parameters did not differ significantly between the groups.
Conclusion
Increased cyclic right atrial volumes and mild alterations in right atrial functional properties could be demonstrated in idiopathic hypereosinophilic syndrome patients.
Zusammenfassung
Hintergrund
Das idiopathische hypereosinophile Syndrom ist gekennzeichnet durch eine persistierende Eosinophilenzahl im Blut >1,5 × 109 Zellen/l und Organschäden, unabhängig von den primären und sekundären Ursachen der Eosinophilie. Ziel der vorliegenden Studie war es, die in der 3‑D-Speckle-Tracking-Echokardiographie ermittelten volumetrischen und funktionellen Eigenschaften des rechten Vorhofs zwischen Patienten mit hypereosinophilem Syndrom und entsprechenden Kontrollen zu vergleichen.
Methoden
Insgesamt wurden 11 Patienten mit idiopathischem hypereosinophilem Syndrom und 22 in Alter und Geschlecht entsprechend ausgewählte gesunde Kontrollen in die Studie aufgenommen. Die 3‑D-Speckle-Tracking-Echokardiographie wurde für die Ermittlung rechtsatrialer Volumina, volumenbasierter funktioneller Eigenschaften und von Dehnungsparametern eingesetzt.
Ergebnisse
Eine signifikante Erhöhung der rechtsatrialen Maximal- (68,7 ± 33,1 ml vs. 40,3 ± 12,1 ml; p = 0,001) und Minimalvolumina (48,3 ± 31,0 ml vs. 28,3 ± 9,4 ml; p = 0,009) sowie der rechtsatrialen Volumina vor der Vorhofkontraktion (58,6 ± 27,3 ml vs. 34,5 ± 11,8 ml; p = 0,001) wurde bei Patienten mit hypereosinophilem Syndrom im Vergleich zu Kontrollen festgestellt. Die Gesamt- und die passiven rechtsatrialen Schlagvolumina erwiesen sich bei Patienten mit hypereosinophilem Syndrom als signifikant erhöht. Die globalen und durchschnittlichen segmentalen Deformationsparameter unterschieden sich nicht signifikant zwischen den Gruppen.
Schlussfolgerung
Erhöhte zyklische rechtsatriale Volumina und leichte Veränderungen der rechtsatrialen funktionellen Eigenschaften waren bei Patienten mit idiopathischem hypereosinophilem Syndrom nachweisbar.
