Abstract

Objective: Short episodes of myocardial ischemia during coronary angioplasty may induce oxidative stress and increase lipid peroxidation. The aim of this study was to determine the effect of metoprolol on lipid peroxidation by measurements of malondialdehyde (MDA) and total antioxidant capacity (TRAP) in patients undergoing angioplasty. The relations between homocysteine level and lipid peroxidation were also studied. Methods: Forty-six patients (mean age 57 years, 37 males) undergoing elective angioplasty were enrolled. Metoprolol treatment was initiated in 27 patients (group 1), meanwhile 19 patients could not take metoprolol due to diverse contraindications (group 2). Results: Following angioplasty, while venous MDA levels decreased in group 1 (0.188±0.021 vs. 0.159±0.020 nmol/ml, p=0.05), an increase was detected in group 2 (0.203±0.025 vs. 0.229±0.024 nmol/ml, p=0.045) as compared with baseline levels. In group 1, TRAP levels markedly increased after angioplasty in venous samples (1.201±0.036 vs. 1.478±0.044 mmol/L, p=0.0001). However, small increase was observed for TRAP in group 2 (1.274±0.043 vs. 1.363±0.053 mmol/L, p=0.05). There was no significant change in plasma homocysteine levels with angioplasty. There was no significant correlation between homocysteine, changes in MDA and TRAP levels either. Conclusion: Administration of metoprolol may cause a reduction in the oxidative stress and an increase in the antioxidant activity in patients undergoing elective angioplasty.

Özet

Amaç: Koroner anjiyografi esnasındaki kısa süreli miyokardiyal iskemi atakları oksidatif strese neden olabilir ve lipid peroksidasyonunu artırabilir. Bu çalışmada, anjiyoplasti yapılan hastalarda, malondialdehid (MDA) ve total antioksidan kapasite (TAK) ölçümü yardımı ile metoprololün lipid peroksidasyonu üzerine olan etkisinin araştırılması amaçlandı. Ayrıca homosistein ve lipid peroksidasyon ürünleri arasındaki ilişki incelendi. Yöntemler: Elektif anjiyoplasti yapılan 46 hasta (yaş ortalaması: 57, 37 erkek) çalışmaya alındı. Yirmi yedi hastaya metoprolol tedavisi başlanırken (grup 1), farklı kontrendikasyonlar sebebi ile 19 hasta metoprolol alamadı (grup 2). Bulgular: Anjiyoplasti sonrası, grup 1'de venöz MDA seviyeleri azalırken (0.188±0.021 ve 0.159±0.020 nmol/ml, p=0.05), grup 2'de MDA seviyelerinde artış gözlendi (0.203±0.025 ve 0.229±0.024 nmol/ml, p=0.045). Grup 1'de venöz örneklerde TAK düzeyleri anjiyoplasti sonrası önemli miktarda arttı (1.201±0.036 ve 1.478±0.044 mmol/L, p=0.0001). Fakat, grup 2'de hafif bir artış gözlendi (1.274±0.043 ve 1.363±0.053 mmol/L, p=0.05). Anjiyoplasti ile plazma homosistein seviyelerinde önemli bir değişiklik olmadı. Ayrıca, homosistein düzeyleri ile MDA ve TAK ölçümündeki değişiklikler arasında önemli bir korelasyon gözlenmedi. Sonuç: Elektif anjiyoplastiye giden hastalarda metoprolol kullanımı, oksidatif streste azalma ve antioksidan aktivitede artış sağlayabilir.
