Sol Koroner Arter Bifurkasyon Açısı ve Sol Ana Koroner Arter Uzunluğunun Aterosklerotik Plak Yükü Üzerine Etkisi

ÖZ GİRİŞ ve AMAÇ: Koroner arter hastalığı (KAH) önemli bir halk sağlığı sorunudur. Gensini skorlama sistemi (GS) klinik pratikte ateroskleroz yükü, KAH yaygınlığı ve ciddiyetini belirlemede kullanılan en popüler skorlama yöntemlerinden birisidir. Daha önce yapılmış çalışmalarda geniş açılanma ile ciddi koroner arter darlığı arasında korelasyon olduğu gösterilmiştir. Bu çalışmada, koroner arter bifurkasyon açısı ve LMCA uzunluğunun koroner aterosklerotik yük ile ilişkini incelemeyi amaçladık. YÖNTEM ve GEREÇLER: Koroner anjiografi yapılan hastalar incelendi. Akut koroner sendromu, normal koroner arterleri, LMCA osteal lezyonu, LAD osteal lezyonu, CX osteal lezyonu, bifurkasyon açısının ölçümü için yeterli görüntüleme yapılamamış olan hastalar dışlandı. 2 deneyimli kardiyolog tarafından "extreme pacs" yazılım sistemi kullanılarak çalışmaya dahil edilen hastaların LAD-CX bifurkasyon açısı ve LMCA uzunluğu ölçüldü. Dahil edilen hastaların aterosklerotik plak yükü GS kullanılarak hesaplandı. BULGULAR: 63 hasta (36 erkek, 27 kadın) çalışmaya dahil edildi. LAD-Cx bifurkasyon açısı ile gensini skoru arasında kuvvetli pozitif korelasyon mevcuttu (r= 0,854; p

Effect of Left Coronary Bifurcation Angle and Left Main Coronary Artery Length on Coronary Artherosclerotic Plaque Burden

ABSTRACTINTRODUCTION: Coronary artery disease (CAD) is animportant public health problem. The Gensini score system(GS) is one of the most popular coronary scoring systems usedin clinical practice to determine the atherosclerotic burden,extent and severity of CAD. Previous studies have showed thedirect correlation between wide angulation and significantcoronary stenosis. In this study we analysed the effect ofcoronary bifurcation angle and left main coronary artery(LMCA) length on the coronary atherosclerotic burden.METHODS: Patients, who underwent coronary angiographywere scanned. Patients having; acute coronary syndrome,normal coronary arteries, LMCA lesion, osteal left anteriordescending (LAD) coronary artery lesion, osteal circumflex(CX) coronary artery lesion, inadequate visualisation forbifurcation angle measurement were excluded. LAD-CXcoronary artery bifurcation angle and LMCA length ofincluded patients were analysed by 2 experienced cardiologistsby using "extreme pacs" software system. Atheroscleroticburden of included patients were determined by GS.RESULTS: 63 patients (36 male, 27 female) were included.There was a strong positive correlation between LAD-CXbifurcation angle and gensini score (r= 0,854; p
