Abstract

Intracoronary thrombus occurring by disruption of atherosclerotic plaque is the cause of acute coronary syndromes. Vulnerable atherosclerotic plaques were found to contain a large number of macrophages and T lymphocytes and that the secretion of neopterin from activated macrophages increased in vulnerable plaques. Our study aimed to assess serum neopterin concentrations as an indicator of intracoronary plaque inflammation and their relation to coronary artery disease severity in patients with acute coronary syndrome (ACS). Consecutive 43 patients with chronic stable angina pectoris (group I), 118 patients with ACS (group II) and age-matched 30 healthy subjects as a control group (group III) were enrolled in our study. Serum neopterin concentration was measured with "enzyme-linked immunosorbent assay" technique. Selective coronary angiography was performed all patients. Significant coronary artery disease was defined as >50% narrowing on coronary angiogram. Severity of coronary artery disease was evaluated using Gensini score. Serum neopterin concentrations were found 12.33±3.94 nmol/L in group I, 22.46±6.75 nmol/L in group II, and 9.02±2.57 nmol/L in group III. Serum neopterin levels were found significantly higher in ACS than in patients with chronic stable angina pestoris (p

Özet

Giriş ve amaç: Aterosklerotik plağın yırtılması ile oluşan intrakoroner trombüs akut koroner sendromun (AKS) temel nedenidir. Yırtılmaya hassas plakların, daha fazla sayıda makrofaj ve T lenfosit ihtiva ettiği çeşitli çalışmalarla tespit edilmiştir. Ayrıca hassas plaklardaki aktive olmuş makrofajlardan da neopterin salgısının arttığı bilinmektedir. Bu çalışma AKS'li ve stabil angina pektorisli olgularda plak inflamasyonunun bir kriteri olarak serum neopterin seviyesinin ölçümü ve bunun koroner arter hastalığının (KAH) anjiyografik şiddeti ile ilişkisi olup olmadığını araştırmak amacı ile yapıldı. Gereç ve yöntem: Çalışmaya ardışık 43 stabil angina (grup I) ve 118 AKS'li (grup II) hasta ile kontrol grubu olarak aynı yaşlarda sağlıklı 30 birey (grup III) alındı. Serum neopterin düzeyi "enzym-linked immunosorbent assay" (ELİSA) tekniği ile ölçüldü. Tüm olgulara selektif koroner anjiyografi yapıldı. Koroner anjiyografide >%50 darlık tespit edilmesi önemli koroner hastalığı olarak kabul edildi. Anjiyografik olarak KAH'ın şiddeti ise Gensini skorlaması ile değerlendirildi. Bulgular: Serum neopterin düzeyi grup I= 12.33±3.94 nmol/L, grup II= 22.46±6.75 nmol/L ve grup III= 9.02±2.57 nmol/L bulundu. AKS'li olgulardaki serum neopterin düzeyi hem stabil anginalı olgulara göre (p
