Abstract

Objective: Ghrelin exerts protective effects on cardiovascular system by inhibiting progression of atherosclerosis, supres- sion of vascular inflammation, and stimulating angiogenesis. Thus, the aim of this study was to investigate the effect of se- rum ghrelin on coronary collateral development and SYNTAX score in patients with severe coronary artery disease. Methods: Total of 91 patients who had >=90% stenosis in at least one major coronary artery were prospectively included in this cross-sectional, observational study. Collateral degree was graded according to Rentrop-Cohen classification. Pa- tients with grade 2 or 3 collateral degree were allocated to Good Collateral Group and patients with grade 0 or 1 collater- al degree were included in Poor Collateral Group. Ghrelin and vascular endothelial growth factor A (VEGF-A) levels were measured using radioimmunoassay and ELISA kits. Results: Serum ghrelin and VEGF-A levels were significantly higher in Good Collateral Group. Furthermore, ghrelin level showed significant inverse correlation with SYNTAX score (r=- 0.348; p=0.001). In multivariable regression analysis, ghrelin (Odds ratio, 1.013; 95% confidence interval, 1.011-1.017; p=0.013), VEGF-A, fasting plasma glucose and presence of chronic total occlusion were independent predictors of good collateral development. In receiver operating characteristic curve analysis, ghrelin value cut-off point of >=781 pg/mL pre- dicted good collateral development with sensitivity of 73.1% and specificity of 67.7%. Conclusion: Findings suggested that ghrelin has antioxidant and antiinflammatory properties that protect endothelial func- tions and also stimulate angiogenesis, which results in devel- opment of good coronary collateral and inhibition of progres- sion of coronary atherosclerosis.

Özet

Amaç: Ghrelin ateroskleroz ilerleyişini engelleyerek, damarenflamasyonunu baskılayarak ve yeni damar oluşumunu uyararakkardiyovasküler sistem üzerinde koruyucu bir etki yaratmaktadır.Bu nedenle, bu çalışmanın amacı ciddi koronerarter hastalığı olan hastalarda serum ghrelin düzeyinin koronerkollateral gelişimi ve SYNTAX skoru üzerindeki etkisiniincelemektir.Yöntemler: En az bir büyük koroner arterinde >=%90 darlıkolan toplam 91 hasta ileriye dönük olarak bu kesitsel-gözlemselçalışmaya alındı. Kollateral derecelendirilmesi Rentrop-Cohensınıflamasına göre yapıldı. Grade 2 veya 3 kollaterali olanhastalar iyi kollateral grubuna, grade 0 veya 1 kollaterali olanhastalar ise kötü kollateral grubuna dahil edildi. Serum ghrelinve vasküler endotelyal büyüme faktörü A (VEGF-A) düzeyleriradyoimünoanaliz ve ELISA kitleri kullanılarak ölçüldü.Bulgular: Serum ghrelin ve VEGF-A düzeyleri iyi kollateralgrubunda anlamlı derecede daha yüksekti. Üstelik, Spearmankorelasyon analizinde ghrelin ile SYNTAX skoru (r=-0.348,p=0.001) arasında anlamlı ters bir korelasyon vardı. Çokdeğişkenlilojistik regresyon analizinde ghrelin (odds oranı[OO]: 1.013; %95 güven aralığı [GA]: 1.011-1.017; p=0.013),VEGF-A, açlık plazma glukozu ve kronik tam tıkanma varlığı-nın iyi koroner kollateral gelişiminin bağımsız öngördürücüleriolduğu gösterildi. ROC (Receiver operating characteristic) eğ-risi analizinde ise serum ghrelin kestirim değeri >=781 pg/mLalındığında, iyi koroner kollateral gelişimini %73.1 duyarlılıkve %67.7 özgüllük ile öngördürdüğü saptandı.Sonuç: Ghrelinin antioksidan ve antienflamatuvar özelliklerisayesinde endotel fonksiyonlarını koruyarak ve yeni damaroluşumunu uyararak iyi koroner kollateral gelişimini sağlarkenaynı zamanda koroner ateroskleroz gelişimini engellediği sonucuçıkarılabilir.
