Abstract

fetched live from OpenAlex

Amaç: Bu çalışmada, koroner arter baypas cerrahisi (KABC) ile tam revaskülarizasyon sağlanamayan hastalarda transmiyokardiyal lazer revaskülarizasyonu (TMR) uygulamasının anjinal yakınmalar ve klinik sonuçlar üzerindeki etkileri araştırıldı. Ça­lış­ma pla­nı: 2003-2006 yılları arasında KABC uygulanan ancak tam revaskülarizasyon sağlanamayan 45 hastaya ait veriler geriye dönük olarak incelendi. Bu gruptan 35 hastaya (ort. yaş 61.7) sadece KABC, 10 hastaya (ort. yaş 62) ise KABC ile eşzamanlı olarak TMR işlemi yapılmıştı. Hastalar üçüncü ayda ve ortalama 22.3±6.1 ay olan takip süresinin sonunda transtorasik ekokardiyografi ve perfüzyon sintigrafisi ile incelendi. Anjinal semptomlar CCS (Canadian Cardiovascular Society) sınıflamasına göre değerlendirildi. Bul­gu­lar: İki grubun ameliyat öncesi verileri benzer bulundu. Hastaların tümü semptomatikti (CCS sınıfı TMR grubunda 2.6±0.5, sadece KABC grubunda 2.3±0.8). Kardiyopulmoner baypas (KPB) süresi TMR grubunda daha uzun idi (p=0.022). Ameliyat sonunda TMR grubunda düşük-orta doz inotrop desteğine daha az ihtiyaç duyuldu (TMR grubunda %10, sadece KABC grubunda %48.6; p=0.034). Erken mortalite hiçbir hastada gözlenmezken, üç hastada (TMR grubunda 1 hasta, sadece KABC grubunda 2 hasta; p=0.329) geç mortalite görüldü. Üçüncü ayda TMR grubundaki hastaların %50’si (n=5) asemptomatik iken, sadece KABC grubunda hastaların %14.3’ü (n=5) asemptomatikti (p=0.016). Anjinal semptomlarda düzelme TMR grubunda anlamlı derece daha fazla idi (CCS sınıfı 3. ay 1.2±0.6 ile 2.2±0.7; p=0,001 ve takip sonu 1±0.6 ile 2±0.7; p=0.001). Miyokart perfüzyon sintigrafisi ve ekokardiyografi ile kontrollerde iki grup arasında anlamlı fark görülmedi. So­nuç: Tam cerrahi revaskülarizasyon sağlanamayan hastalarda TMR uygulaması KPB’den ayırma işlemi sırasında inotropik destek ihtiyacını, kısa ve orta dönemde anjinal yakınmaları azaltmaktadır.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
