Koroner Arter Hastalığı ile Karotis İntima-Media Kalınlığı Arasındaki İlişkinin Değerlendirilmesi

Amaç: 64 kesitli bilgisayarlı tomografi anjiografi (BTA) ile tespit edilen koroner arter hastalığı (KAH) ve ultrasonografi (US) ile izlenen ana karotis arterdeki (ACA) intima-media kalınlığı (İMK) arasındaki ilişkiyi araştırmaktır.Gereç ve Yöntem: Çalışmaya koroner BTA için gönderilen 214 olgu dahil edildi. Tüm olgulara 64-kesitli BTA cihazı ile inceleme ve KAH varlığı yönünden Gensini skorlaması (GS) yapıldı. Bütün olgulara 64 kesitli BTA sonrası, İMK açısından ACA’nın değerlendirilmesi için US cihazı ile bakıldı. BTA değerlendirmesi ve US bakısı birbirinden bağımsız iki radyolog tarafından yapıldı. İMK ve plak değerlendirilmesi için Spearman’ın korelasyon testi, ROC analizi, regresyon grafikleri ve linear grafikleri kullanıldı. Bulgular: Çalışmamıza dahil edilen 214 olgudan 94 tanesi erkek, 120 tanesi kadındı. Olguların ortalama yaşı 55,112±0,74 idi. Ortalama GS erkeklerde 8,94±1,038, kadınlarda 5,35±0,715 idi. Cinsiyet ile GS arasında, yaş ile GS arasında, ortalama intima-media kalınlığı (ORT-İMK) ve en yüksek intima-media kalınlığı (EY-İMK) ile GS arasında anlamlı korelasyon olduğu bulundu. Yine plak varlığı ile GS arasında ve yaşla plak arasında anlamlı korelasyon saptandı. Sonuç: Çalışmamızda GS ile yaş arasında anlamlı ilişki izlenmekte olup ileri yaşlarda KAH sıklığında artış görülmekte, ORT-İMK ve EY-İMK değerleri ile plak varlığı ve GS arasında da anlamlı ilişki bulunmaktadır. Ayrıca karotis arterde plak ya da İMK artışı şeklinde izlediğimiz aterosklerotik değişikliklerin KAH’ı öngörmede anlamlı olduğu düşünülmüştür. Popülasyon tabanlı çalışmaların yapılması ile KAH’ın erken tespitinde İMK’nın tarama testi olarak kullanılmasında umut verici sonuçlar ortaya çıkabilir

Koroner Arter Hastalığı ile Karotis İntima-Media Kalınlığı Arasındaki İlişkinin Değerlendirilmesi

Objective: To investigate the relationship between carotid artery disease detected by 64-slice computed tomography angiography (CTA) and the common carotid artery (CCA) in carotid intima-media thickness (IMT) followed by ultrasonography (US). Material and Methods: The study included 214 cases that were referred for coronary CTA. Sixty-four-slice CTA in all cases was performed with the examination for the presence of CAD, Gensini score (GS) was performed. After 64-slice CTA in all cases, the CCA IMT was evaluated by US devices. Evaluation of the CTA and US examination were performed by two radiologists who are independent from each other. Spearman's correlation test for the evaluation of IMT and plaque, ROC analysis, linear regression graphs and charts were used. Results: Of 214 patients, 94 were male, and 120 of them were women. The average age was 55.112 ± 0.74. In females average GS was 5.35 ± 0.715, in men it was 8.94 ± 1.038. Gender, age, average-IMT and maximum-IMT were found to be correlated with the GS. The GS and the presence of plaque, and age and plaque were significantly correlated. Conclusion: We have found a significant correlation between GS and age, increasing CAD risk in older ages. In addition, the average-IMT and the highest-value was significantly correlated with plaque and GS. In addition, we suggest the formation of carotid artery plaque or increased IMT (arteriosclerotic changes) are essential in predicting CAD. Population-based studies for early detection of CAD with the use of IMT as a screening test could yield promising findings
