Abstract
Introduction
Inflammation has been reported to be associated with aortic dissection (AD), from the development to the prognosis of AD. In this study we aimed to find the role of the neutrophil-lymphocyte ratio (NLR) in the prediction of clinical events in patients with acute AD type A.
Patients and methods
The study comprised 37 patients who were hospitalized at our center between 2009 and 2013 with the diagnosis of acute AD type A.
Results
The mean NLR was significantly higher in patients with pericardial effusion than those without effusion (15.6 ± 11.4 vs. 7.5 ± 4.8, p = 0.005). An NLR value > 8.51 yielded an area under the curve (AUC) value of 0.829 [95 % confidence interval (CI) 0.674–0.984, p = 0.004], which demonstrated a sensitivity of 77 % and specificity of 74 % for the prediction of mortality.
Conclusions
The novel inflammatory marker NLR could be used to predict pericardial effusion and in-hospital mortality in patients with acute AD type A.
Zusammenfassung
Einleitung
Zum Zusammenhang von Inflammation und Aortendissektion (AD) ist publiziert worden, von ihrer Entwicklung einer AD bis zu ihrer Prognose. Ziel der Studie war es, die Rolle des Verhältnisses von Neutrophilen zu Lymphozyten („neutrophil/lymphocyte ratio“, NLR) in der Prädiktion von klinischen Ereignissen bei Patienten mit akuter AD vom Typ A zu eruieren.
Methoden
Die Studienpopulation bestand aus 37 Patienten, die zwischen 2009 und 2013 mit der Diagnose akute AD Typ A in unsere stationäre Behandlung aufgenommen worden waren.
Ergebnisse
Bei Patienten mit Pleuraerguss war die NLR signifikant höher als bei Patienten ohne Erguss (15,6 ± 11,4 vs. 7,5 ± 4,8, p = 0,005). Der NLR-Wert > 8,51 ergab einen AUC („area under the curve“)-Wert von 0,829 (95 %-KI 0,674–0,984; p = 0,004), entsprechend einer Sensitivität von 77 % und einer Spezifität von 74 % für die Prädiktion der Mortalität.
Fazit
Der neue Inflammationsmarker NLR ermöglicht bei akuter AD vom Typ A eine Prädiktion von Perikarderguss und stationärer Mortalität.
