Abstract

Objective: Slow coronary flow (SCF) is an angiographic finding characterized with delayed opacification of epicardial coronary arteries without obstructive coronary disease. CD40/CD40 ligand (CD40L) signaling seems closely related to atherosclerosis due to increased inflammation and prothrombotic state. We investigated whether soluble CD40 (sCD40), an indirect marker of CD40/CD40L dyad, is related to SCF. Methods: The present study was cross-sectional and observational, consisting of seventy individuals who underwent coronary angiography with suspicion of CAD and had angiographically normal coronary arteries of varying coronary flow rates. The relationship between sCD40, C-reactive protein (CRP) and SCF phenomenon was investigated. Fifty patients with isolated SCF (mean age: 56±10 years) and 20 age- and gender-matched control participants with normal coronary flow (NCF) and normal coronary arteries (NCA), (mean age: 55±10 years) were included in the study. We used logistic regression analysis to determine the predictors of SCF. Results: The clinical characteristics were not statistically significant different between SCF and NCA group. Serum CRP levels were also simi- lar between two groups. Serum sCD40 level was significantly higher in the SCF group compared to control group (74±31 vs. 59±16 pg/mL, p=0.014). In multiple regression analyses, mean coronary diameter strongly (OR: 7.358, 95% CI: 1.990-27.20, p=0.003) and sCD40 (OR: 1.044, 95% CI: 1.006-1.084, p=0.023) weakly predicted SCF. Conclusion: This study revealed, significantly increased serum sCD40 levels in patients with SCF. Although we cannot conclude the underlying pathological process of SCF, we believe that these findings may be pivotal for further studies searching the specific roles of CD40/CD40L signal- ing on SCF phenomenon in coronary vasculature.

Özet

Amaç: Koroner yavaş akım (KYA) epikardiyal koroner arterlerin obstrüktif hastalık olmaksızın yavaş dolması ile karakterize bir durumdur. CD40/ CD40 ligandı (CD40L) sistemi artmış enflamasyon ve protrombotik yatkınlık sebebiyle aterosklerozla yakın ilişkili gibi görünmektedir. Biz, CD40/ CD40L ikilisinin indirekt bir göstergesi olan serum çözünmüş CD40 (çCD40) düzeylerinin KYA ile ilişkisini araştırmayı hedefledik. Yöntemler: Çalışmamız gözlemsel ve kesitsel nitelikte olup, koroner arter hastalığı şüphesi ile koroner anjiyografi yapılan ve değişken akım hızlarında normal koroner arterler saptanan 70 hasta içeriyordu. KYA, çCD40 ve C-reaktif protein (CRP) arası ilişki incelendi. Çalışmaya KYA’sı olan 50 hasta (ort. yaş 56±10) ve koroner akımı ve koroner arterleri normal (NKA) 20 yaş-cinsiyeti uyumlu kontrol hastası (Ort. yaş 55±10) alındı. KYA’ın öngörücülerini belirlemede lojistik regresyon analizi kullanıldı. Bulgular: KYA ve NKA grubu arasında klinik karakteristikler ve CRP düzeyleri açısından farklılık saptanmadı. Serum çCD40 düzeyi KYA grubunda NKA grubuna göre anlamlı düzeyde yüksek (74±31 - 59±16 pg/mL, p=0.014) saptandı. Çok değişkenli analizde, ortalama koroner çapı kuvvetli (OR: 7.358, %95 CI: 1.990-27.20, p=0.003) ve çCD40 (OR: 1.044, %95 CI: 1.006-1.084, p=0.023) düzeyi zayıf bir KYA belirteci olarak saptandı. Sonuç: Çalışmamızda, KYA akım hastalarında artmış çCD40 konsantrasyonun var olduğunu ilk defa ortaya koyduk. Biz, KYA’nın altta yatan patofizyolojik sürecini netleştiremesek de, bulgularımızın KYA fenomeni gelişiminde çCD40/CD40L sisteminin özgül rollerinin daha iyi anlaşılmasında öncül rol oynayabileceğine inanıyoruz.
