Statistically significant increases in lumen diameter and area were observed in nifedipine (p=0007), amlodipine (p=0.003) and nebivolol (p=0.047) groups.Conclusion: Our results demonstrate that calcium channel antagonists are not equally effective in radial artery vasodilatation.

Abstract

Background: In this study, the vasodilatory effects of calcium antagonists and beta-blockers were investigated.Methods: After obtaining Faculty Ethics Committee approval and written informed consent from the patients, 72 adult patients (50 males, 27 females; mean age 62.9±9.3 years; range 37 to 75 years) who will undergo elective coronary artery bypass grafting (CABG) surgery were included in this study. We evaluated the vasodilatory effect of diltiazem alone (group 1), nifedipine alone (group 2), amlodipine alone (group 3), nebivolol alone (group 4) and nifedipine in combination with metoprolol (group 5). Seventy-seven patients who would undergo isolated CABG using radial artery were prospectively randomized to oral agents four or five days before operation. The dilatation of the lumen diameter and area of the radial artery were evaluated with high-resolution ultrasonography just before and 4-5 days after medical treatment.Results: Diltiazem alone group (p=0.058) and niphedipine in combination with metoprolol group (p=0.067) did not show a significant increase in the lumen diameter and area after medical treatment compared to the pretreatment values. Statistically significant increases in lumen diameter and area were observed in nifedipine (p=0007), amlodipine (p=0.003) and nebivolol (p=0.047) groups.Conclusion: Our results demonstrate that calcium channel antagonists are not equally effective in radial artery vasodilatation. Nifedipine, amlodipine and nebivolol appear to be the most effective agents in reducing radial artery spasm. Nebivolol is a betablocker and also has a potent vasodilatory effect on radial ar tery vasospasm.

Özet

Amaç: Bu çalışmada kalsiyum antagonistleri ve betablokörlerin vazodilatatör etkileri araştırıldı.Çalışma planı: Fakülte Etik Kurul onayı ve hastaların yazılı bilgilendirilme onamı alındıktan sonra elektif koroner arter bypass greftleme (KABG) ameliyatı planlanan 72 erişkin hasta (50 erkek, 27 kadın; ort. yaş 62.9±9.3 yıl; dağlım 37-75 yıl) bu çalışmaya dahil edildi. Tek başına diltiazemin (grup 1), tek başına nifedipinin (grup 2), tek başına amlodipinin (grup 3), tek başına nebivololün (grup 4) ve nifedipinin metoprolol ile kombinasyonunun (grup 5) vazodilatatör etkileri değerlendirildi. Radial arter kullanılarak izole KABG ameliyatına giden ardışık 77 hasta ileriye dönük olarak ameliyattan dört ila beş gün önce oral ajanlara randomize edildi. İlaç tedavisinden hemen önce ve tedaviden 4-5 gün sonra radial arterin lumen çapı ve alanındaki dilatasyonu yüksek çözünürlüklü ultrasonografi ile değerlendirildi.Bulgular: Tek başına diltiazem grubu (p=0.058) ve metoprolol ile kombine edilen nifedipin grubu (p=0.067), ilaç tedavisinden önceki lümen çap ve alanları ile kıyaslandığında anlamlı bir artış göstermedi. Nifedipin (p=0.007), amlodipin (p=0.003) ve nebivolol (p=0.047) grubunda lümen çap ve alanında istatistiksel olarak anlamlı artışlar gözlemlendi.Sonuç: Sonuçlarımız kalsiyum kanal antagonistlerinin radial arterin vazodilatasyonunda aynı derecede etkili olmadığını göstermektedir. Nifedipin, amlodipin ve nebivolol radial arter spazmının azaltılmasında en etkili ajanlar gibi görünmektedir. Nebivolol bir beta-blokerdir ve aynı zamanda radial arter vazospazmı üzerinde güçlü bir vazodilatör etkiye sahiptir.
