Abstract

Objectives: Although clinical and pathophysiologic features of slow coronary artery flow (SCAF) have been previously described, the underlying pathophysiology has not been fully elucidated. The aim of this study was to investigate the association between DNA damage and SCAF.Study design: The study was comprised of 23 patients with SCAF and 23 healthy volunteers. DNA damage was assessed by the alkaline comet assay in peripheral lymphocytes and plasma total antioxidant capacity (TAC) was determined by a novel, automated method.Results: Although DNA damage was higher in the SCAF group than in controls, this did not reach significance (106.6±38.2 AU vs 80.5±51.7 AU; p=0.055). Similarly, TAC levels did not differ significantly between the two groups (1.32±0.32 mmol Trolox equiv./L vs 1.35±0.26 mmol Trolox equiv./L, p=0.667). In the patient group, DNA damage showed a positive correlation with age (r=0.775, p

Özet

Amaç: Koroner yavaş akımın klinik ve patofizyolojik özellikleri tarif edilmesine karşın, altta yatan esas mekanizma tam olarak aydınlatılamamıştır. Bu çalışmada koroner yavaş akım ile DNA hasarı arasındaki ilişki değerlendirildi.Çalışma planı: Yavaş akımlı 23 hasta ve 23 sağlıklı gönüllü çalışma gruplarını oluşturdu. DNA hasarı periferik kanda lenfositte alkalen comet yöntemiyle, plazma total antioksidan kapasitesi ise yeni geliştirilen otomatik yöntemle ölçüldü.Bulgular: Koroner yavaş akımlı olgularda DNA hasarı kontrol grubundan daha fazla bulunmasına karşın aradaki fark anlamlı değildi (sırasıyla 106.6±38.2 AU ve 80.5±51.7 AU; p=0.055). İki grup arasında total antioksidan kapasite değerleri açısından da anlamlı farklılık bulunmadı (1.32±0.32 mmol Trolox equiv./L’e karşın 1.35±0.26 mmol Trolox equiv./L, p=0.667). Yavaş akımlı olgularda DNA hasarı yaşla pozitif (r=0.775, p
