Abstract

Preoperative evaluation of the present myocardial stunning in coronary by pass planned patients is an important factor for determination of the surgical strategy. If with an eye to the myocardial pathophylogic differences which occurred after ischemia reperfusion too, the importance of the myocardial damaged coming much definitive. In this study we researched the effect of the EGB 761 extract on myocardial pathologic changes which occurred reperfusion period.This study verified with, randomized, double blind, placebo controlled, elective coronary by pass operation planned, left ventricular functions normal 18 patients. 3x80 mgr EGB 761 extract applied per orally 9 of the patients 5 days before and 2 days after operation. Before, on time and after operation hemodynamic and biochemical differences between groups were evaluation statistically.There were not meaningful differences between groups' mean age, body surface areas, ejection fractions, functional capacities, cross clamp times, CPB times and anastomosis counts. In spite of three patients arrhythmic, one patient needed medical support and respiratory insufficiency developed in one patient in group A, there were not any problem in applied EGB761 group B.As result, symptomatic or asymptomatic myocardial stunning is present in a part of the coronary by pass applied patients. For this reason we are thinking that the use of the EGB761 extract with routinely using myocardial protection methods may be helper for myocardial protection.

Özet

Koroner bypass operasyonu uygulanacak hastalardaki mevcut miyokardiyal stunning'in preoperatif değerlendirmesi cerrahi stratejiyi belirlemede önemli bir faktördür. İskemi sonrası reperfüzyonda ortaya çıkan miyokardiyal fizyopatolojik değişiklikleri de göz önüne alırsak, miyokardiyal korumanın önemi daha belirgin hale gelmektedir. Bu çalışmamızda, reperfüzyon döneminde miyokartta ortaya çıkan patolojik değişikliklere EGb 761 ekstraktının etkisini araştırdık.Bu çalışma, randomize, çift kör, plasebo kontrollü olarak, elektif koroner bypass operasyonu uygulanacak, sol ventrikül fonksiyonları bozulmamış 18 hasta ile gerçekleştirildi. Hastaların 9'una operasyon öncesi 5 gün, operasyon sonrası 2 gün süre ile 3x80 mg EGb 761 ekstraktı oral verildi. Guruplar arasındaki operasyon öncesi, operasyon ve operasyon sonrası; hemodinamik ve biyokimyasal farklılıklar istatistiksel olarak değerlendirildi.Gruplar arasında ortalama yaş, vücut yüzey alanları, ejeksiyon fraksiyonları, fonksiyonel kapasiteleri, kros klemp zamanları, CPB zamanları ve anastomoz sayısı arasında anlamlı bir fark yoktu. Grup A' da üç hastada aritmi, bir hastada medikal destek ve bir hastada solunum yetersizliği gelişmesine rağmen, EGB 761 verilen grup B'de herhangi bir problemle karşılaşılmadı.Sonuç olarak, koroner bypass cerrahisi uygulanan hastaların bir kısmında semptomatik ya da asemptomatik miyokardiyal stunning mevcuttur. Bu nedenle, günümüzde rutin olarak kullanılan miyokardiyal koruma yöntemleri ile birlikte EGB 761 ekstraktının kullanımının miyokardın korunmasında yardımcı olabileceği düşüncesindeyiz.
