Keywords: Koronararterien-Bypass, Myeloperoxidase, Paraoxonase, Postperikardiotomie-Syndrom, Systemisches inflammatorisches Response-Syndrom Introduction: Postpericardiotomy syndrome (PPS) is a specific form of traumatic pericarditis, developing within the confines of a systemic inflammatory response (SIRS). The absence of prognostic markers, can prevent the development of symptoms and complications such as cardiac tamponade, it determined the relevance of the study. The aim of this study was research of functional relationship between myeloperoxidase (MPO) and paraoxonase (PON) in coronary heart disease after coronary artery bypass grafting (CABG). Methods: The study involved 76 patients with coronary artery disease undergoing coronary artery bypass grafting. The patients were divided into 2 groups: 1.) patients without PPS; 2.) patients with clinically established syndrome. Activity of MPO and arylesterase activity of PON were determined in plasma and pericardial fluid. Results: A high inverse correlation between the activities of the enzymes was founded in plasma, Spearman‘s correlation coefficient was –0.83 (p < 0.05). A test was developed to predict the PPS. It is based on the determination of the ratio of the activities of MPO/PON. For blood plasma sensitivity of method for the plasma is 87.5%, specificity –75%, the overall accuracy –80%. For pericardial fluid test criteria are 71.4%, 80% and 71.4%, respectively. Discussion: The efficiency of applying of ratio of the activities of MPO/PON was proved for predict the development of the PPS. Described test will allow to evaluate the likelihood of the syndrome at minimal postoperative periods and to select group patients at risk for targeted therapy.
Kurzfassung: Einleitung: Das Postperikardiotomie-Syndrom (PPS) ist eine spezifische Form der
traumatischen Herzbeutelentzündung, die sich im
Rahmen eines systemisch inflammatorischen Response-Syndroms (SIRS) entwickelt. Das Fehlen
von Prognosemarkern, welche die Entwicklung
des Syndroms und Komplikationen wie Herzbeuteltamponade
vorhersagen können, verdeutlicht
die Aktualität der vorliegenden Studie. Ziel der
Arbeit ist die Untersuchung des funktionellen Zusammenhangs
zwischen Myeloperoxidase (MPO)
und Paraoxonase (PON) bei koronarer Herzkrankheit
nach Koronar-Bypass-Operation (CABG) zur
Prädiktion des PPS. |
