Abstract
Koroner arter hastalığı nedeniyle sol ventrikül fonksiyonları bozulmuş 16 olgunun koroner by-pass ameliyatından önce ve sonra, sol ventrikül fonksiyonları değerlendirilerek miyokard hibernasyonu ve ameliyatın sol ventrikül fonksiyonlarına etkisi araştırıldı. Bu amaçla ameliyat öncesi ve ameliyat sonrası koroner anjiyografi ve sol ventrikülografi yapıldı. Ameliyat sonrasında olguların 11 'inde (% 68) sol ventrikül ejeksiyon fraksiyonu artmış olmasına rağmen 16 olguda toplam 128 miyokard bölgesinden sadece 13 'ünde (% 10) belirgin fonksiyonel iyileşme saptandı. Bu bulgular, miyokard hibernasyonunun koroner arter hastalarında oldukça sınırlı ama çok önemli etkisi olduğunu ortaya koymaktadır.
Sixteen patients with coronary artery disease and impaired left ventricular function underwent coronary artery revascularization in a period of one year. The left ventricular function was measured before and after surgery in all cases. The effect of the surgery on the myocardial hibernation and the left ventricular function was investigated by means of coronary angiography and left ventriculography performed before and after surgery. Although there was an improvement in the left ventricular ejection fraction in 11 (68 %) out of 16 patients, the significant functional improvement was observed only in 13 (10 %) out of 128 myocardial segments in 16 patients. In conclusion, myocardial hibernation has a limited but very important effect in patients undergoing coronary artery revascularization.
