Coronary computed tomographic angiography findings in diabetic patients: A tertiary clinic findings

Öz

Aim: The aim of this study is to identify different types of plaques in diabetic patients suspected of coronary atherosclerosis using coronary computed tomography angiography (CCTA) and assess the extent of coronary artery disease (CAD). Material and Methods: Data from 252 diabetic patients who underwent CCTA were reviewed retrospectively. The mean age of the patients was 60 ± 10 years, and all underwent MSCT angiography. Plaque types were categorized into three groups: calcified, soft, and mixed. Statistical analyses were performed using SPSS v. 15.0 software. Results: Of the 252 diabetic patients, 137 (54.4%) were male and 115 (45.6%) were female. CCTA detected stenosis ≥30% in 40 patients (15%). Calcified plaques (38%) and soft plaques (40%) were observed most frequently in the proximal LAD. CCTA results showed high sensitivity and specificity when compared to invasive angiography. Conclusion: While invasive coronary angiography is considered the gold standard, coronary CTA is a reliable and non-invasive method for evaluating atherosclerosis in diabetic patients. Its high negative predictive value may be effective in ruling out bypass graft stenosis and can reduce the need for invasive procedures, minimizing patient risk.

Diyabetli hastalarda koroner bilgisayarlı tomografi anjiyografi bulguları: Üçüncü basamak klinik bulguları

Öz

Amaç: Bu çalışmanın amacı, koroner ateroskleroz şüphesiyle değerlendirilen diyabetik hastalarda, koroner bilgisayarlı tomografi anjiyografi (CCTA) kullanarak farklı plak tiplerini tanımlamak ve koroner arter hastalığının (KAH) kapsamını değerlendirmektir. Gereç ve Yöntemler: CCTA uygulanan 252 diyabetik hastanın verileri retrospektif olarak incelendi. Hastalara CT anjiyografi uygulandı. Plak tipleri, kalsifiye, yumuşak ve miks olmak üzere üç gruba ayrıldı. İstatistiksel analizler SPSS v. 15.0 yazılımı ile yapıldı. Bulgular: Toplamda 252 diyabetik hastanın 137'si (%54,4) erkek, 115'i (%45,6) kadındır. CCTA, %30 ve üzeri darlık bulunan 40 hastada %15 oranında stenoz bulguları tespit etti. En çok kalsifiye (%38) ve yumuşak plaklar (%40) proximal LAD’de gözlemlendi. Koroner anjiyografi sonuçları ile CCTA'nın bulguları karşılaştırıldığında, CCTA'nın tespit ettiği progresyonlar arasında yüksek bir duyarlılık ve özgüllük olduğu görüldü. Sonuçlar: İnvaziv koroner anjiyografi altın standart olarak kabul edilse de , koroner CCTA, diyabetik hastalarda aterosklerozun değerlendirilmesi için güvenilir ve non-invaziv bir yöntemdir. CCTA'nın yüksek negatif prediktif değeri, bypass greft stenozunu dışlamakta etkili olabilir ve invazif prosedür gereksinimini azaltarak hasta riskini minimize edebilir.
