Beneficial effects of nebivolol treatment on oxidative stress parameters in patients with slow coronary flow

Öz:

Amaç: Koroner yavaş akım (KYA) olan hastalarda oksidatif stres ile antioksidan savunma arasında dengesizlik gösterilmiştir. Bu çalışmada, KYA hastalarında nebivolol tedavisinin oksidatif stres parametreleri üzerine etkisi araştırıldı.Çalışma planı: Çalışmaya KYA saptanan 32 hasta (10 kadın, 22 erkek; ort. yaş 53.3±5.2) ve anjiyografide koroner arterleri normal bulunan 32 kontrol (14 kadın, 18 erkek; ort. yaş 50.6±5.2) alındı. Koroner yavaş akım TIMI kare sayısı yöntemiyle belirlendi. Koroner yavaş akım olan hastalara altı ay süreyle 5 mgr/gün dozunda nebivolol tedavisi uygulandı. Kontrol grubundan ve KYA hastalarından başlangıçta ve altı ay süreyle nebivolol tedavisi sonrasında alınan kan örneklerinde malondialdehit (MDA) ve serum nitrik oksit (NO) düzeyleri, eritrosit katalaz (CAT) ve eritrosit süperoksit dismutaz aktiviteleri (SOD) ölçüldü.Bulgular: İki grup yaş, beden kütle indeksi, kan basıncı, kalp hızı ve lipit profili yönünden benzer özelliklerdeydi. Koroner yavaş akım grubunda sigara içme kontrollere göre daha yaygındı. Sol ön inen, sirkumfleks ve sağ koroner arterlerden ölçülen TIMI kare sayıları KYA grubunda anlamlı derecede fazla bulundu (p<0.0001). Kan incelemesinde başlangıç MDA ve NO düzeyleri ve SOD ve CAT aktiviteleri iki grup arasında anlamlı farklılık gösterdi; MDA KYA grubunda anlamlı derecede artmış bulunurken (p<0.0001), SOD (p<0.0001), CAT (p<0.001) ve NO (p<0.001) anlamlı derecede düşük değerler sergiledi. Nebivolol tedavisi sonrasında altıncı ayda oksidatif stres parametrelerinin tümünde başlangıç değerlerine göre anlamlı düzelmeler görüldü (MDA, SOD, CAT, ve NO için p<0.0001). Bu parametrelerin hepsi kontrol grubundaki değerlere yaklaşmıştı.Sonuç: Bulgularımız nebivolol tedavisinin, aterosklerozun erken evresi olarak kabul edilen KYA’da oksidatif stres parametrelerinin iyileştirilmesinde yararlı olabileceğini göstermektedir.

Objectives: Imbalance between oxidative stress and antioxidant defense has been demonstrated in patients with slow coronary flow (SCF). The aim of this study was to investigate the effect of nebivolol treatment on oxidative stress parameters in SCF patients. Study design: The study included 32 patients (10 females, 22 males; mean age 53.3±5.2 years) with SCF and 32 control subjects (14 females, 18 males; mean age 50.6±5.2 years) with normal coronary arteries on angiography. Coronary slow flow was determined by the TIMI frame count method. Patients with SCF received nebivolol treatment (5 mg/day) for six months. Blood samples were analyzed for malondialdehyde (MDA) and serum nitric oxide (NO) levels, and erythrocyte catalase (CAT) and erythrocyte superoxide dismutase (SOD) activities in the control group and, in SCF patients, at baseline and after six months of nebivolol treatment.Results: The two groups were similar with respect to age, body mass index, blood pressure, heart rate, and lipid profile. Smoking was more frequent in the SCF group compared to the controls. TIMI frame counts measured from the left anterior descending, circumflex, and right coronary arteries were significantly higher in the SCF group (p<0.0001). Baseline MDA and NO levels, and SOD and CAT activities were significantly different between the two groups, with significantly increased MDA (p<0.0001), and significantly decreased SOD (p<0.0001), CAT (p<0.001), and NO (p<0.001) in the SCF group. After six months of nebivolol treatment, all oxidative stress parameters showed significant improvements compared to the baseline values (p<0.0001 for MDA, SOD, CAT, and NO) and approximated to the values of the control group.Conclusion: Our results show that nebivolol treatment may be beneficial to improve oxidative stress parameters in patients with SCF, which is considered to be an early stage of atherosclerosis.
