İşte, HM bizim domuz modeli doğru bir şekilde tek damar hastalığı olan hastalarda klinik deneyimi taklit eder ve sol ventrikül fonksiyonları korunmuş göstermektedir. Revaskülarizasyon öncesinde tek gemi HM hayvanlarla ejeksiyon fraksiyonu göre ölçülen genel işlevinde en az bozulma ama bölgesel duvar kalınlaşma Haritayı önemli azalma sergi. Revaskülarizasyon CMR düşsel vasıl bir ya da üç ay kurtarma kalıcı bölgesel fonksiyon bozukluğu, düşük doz dobutamin stres testi ile contractile rez...

Koroner kalp hastalığı (KKH) yaklaşık 15.5 milyon kişi Amerika Birleşik Devletleri 1 etkiler ve genel olarak ölüm sebeplerinden biridir. KKH ile ilişkili ölüm oranı son yıllarda aşağı gitti, insidans ve hastalar ve sağlık sistemi üzerindeki yükü yüksek 1kalır. Birincil şiddetli CAD revaskülarizasyon, hayatta kalma geliştirir ve angina2,3,4azaltır tedavisidir. Ancak, kardiyak fonksiyon kez özellikle artan iş yükü altında depresif kalır ve kalp yetmezliği5,-6ilerleyebilir. Klinik denemelerin koroner arter bypass cerrahisi (CABG) Kronik iskemi için hayatta kalma ve belirtileri göstermek ama ejeksiyon fraksiyonu % 8-10 7,8sadece mütevazı gelişmeler gösterir. Yenilikçi ve iyi karakterize domuz modelimiz kronik miyokardiyal iskemi klinik CAD ilerici damar darlığı ile bir modeldir. Kan akışı 9kademeli azaltma kaynaklanan indirimli miyokard contractility göstermiştir. Miyokardiyum değil enfarktüsü yapar ve bu senaryoya göre canlı kalabilir. Sonuçlar zamanında revaskülarizasyon değişkenle bile olsa kurtarma mümkündür. Kronik olarak uygun kalır iskemik Miyokardiyum düşük kan akımı ile karakterize ve fonksiyon için tutulan contractile rezerv dinlenerek HM olarak adlandırdığı ve CABG tedavi gerektirir. Her ne kadar HM revaskülarizasyon contractile işlevi geri yüklemelisiniz, deneysel ve klinik gözlem kurtarma eksik8,10olduğunu ispat.
Bölgesel kan akışı11varlığı işlevsiz Miyokardiyum azaltılmış henüz HM uygun varlığı ile karakterizedir. Rağmen contractility Engelli ve istirahat, HM metabolik aktivite fonksiyonel ve metabolik rezerv inotropic stimülasyon12altında göstermek yapabiliyor. HM CAD ile hastaların bir çoğu şüpheli olduğunu ve hastalık geniş bir yelpazede kapsar. Bu protokol için klinik senaryo taklit eder delikanlı arter ile sol iç meme arter (LIMA) ile yan yol HM bizim kurulan domuz modeli göstermektedir. Domuz epicardial köprüleme de¤erler yok gibi diğer büyük hayvanlar üzerinde kalp hastalığı mükemmel bir model sağlar. Bu yalnız bölgesel iskemi13' te neden delikanlı stenoz sağlar.
Burada, biz delikanlı arter tek-damar darlığı oluşturarak domuz hazırda bekleme Miyokardiyum inducing cerrahi yöntemi açıklanmaktadır. Kronik iskemi kurulduktan sonra (8 hafta sonrası delikanlı yılanı implant), biz bizim domuz modelindeki HM için tedavi klinik yeniden oluşturma yöntemi açıklamak: bir "off-pump" koroner arter bypass greft. Bu cerrahi yöntemler sadece kronik kalp iskemi, klinik bir modeli eğitim için ama aynı zamanda kalp iskemi bypass cerrahisi etkilerini araştırmak yanı sıra potansiyel alternatif veya ek tedaviler kardiyak iskemi için test için kullanılabilir.

surgical swine model of chronic cardiac ischemia treated by off-pump coronary artery bypass graft surgery

Kardiyak fonksiyon bozar ama enfarktüsü, yol açmaz kronik kalp iskemi hazırda bekleme Miyokardiyum (HM) olarak adlandırılır. Koroner arter hastalığı (CAD) hastaların büyük bir klinik alt var HM, hangi engelliler fonksiyonu, neden yanı sıra aritmi ve gelecekteki kardiyak olaylar için daha yüksek risk altında yerleştirmektedir. Bu durum için standart tedavi revaskülarizasyon olmakla beraber bu kusurlu bir terapi olarak gösterilmiştir. Önceden klinik kardiyak araştırma çoğunluğu bırakarak bu alt büyük ölçüde az hizmet kronik iskemi hastaların kardiyak iskemi, enfarktüsü modelleri üzerinde duruluyor. Domuz insan kalp hastalığı için ideal translasyonel modelleri gibi araştırma bu boşluğu adrese biz domuz, hazırda bekleme Miyokardiyum iyi karakterize ve son derece tekrarlanabilir model geliştirdik. Bu benzersiz hastalığı model oluşturmanın yanı sıra, domuz koroner arter bypass cerrahisi klinik tedavi modeli optimize. Bu doğru bir şekilde kalp hastalığı bypass cerrahisi etkilerini incelemek, hem de ek veya alternatif terapiler araştırmak için bize izin verir. Bu model ameliyatla sol ön inen (evlat) arter içinde genç bir domuz üzerinde bir yılanı Reproduction tarafından tek damar darlığına neden olmaktadır. Domuz büyüdükçe, yılanı kronik iskemi Engelli bölgesel fonksiyon ile sonuçlanan, ancak doku canlılığı koruyarak kademeli bir stenoz oluşturur. Hazırda bekleme Miyokardiyum fenotip kurulması gerçekleştiriyoruz "off-pump" koroner arter bypass greft cerrahisi iskemik bölgenin revascularize için altın standart tedavi kliniği hastalarda için taklit.

İlk hazırda bekleme ameliyat stenoz 70 %'den büyük klinik görüntüleme teknikleri gibi anjiyografi veya kardiyak MRG (şekil 1A) tarafından uyulması gerekir. 8 hafta delikanlı yılanı cerrahi uygulama aşağıdaki bölgesel işlev yankı ya da kardiyak MRG tarafından analiz azaltılmış işlev artan iş yükü (Şekil 2) altında ortaya koymaktadır. Bu dobutamin (5 mg/kg/dak) kalple uyarıcı ve çev...
