Abstract

Aim: The slow coronary flow (SCF), a distinct angiographic finding characterized by presence of Thrombolysis in Myocardial Infarction (TIMI) -2 flow in the absence of coronary disease, pathophysiologically related to endothelial' and microvascular dysfunction. Previous studies, it has been shown that oral diprydamole could correct the SCF angiographically. The aim of this study is to evaluate the effect of diprydamole on endothelial; functions tested from the forearm, SCF which is physiopathologically related to endothelial dysfunction.Material and methods: 28 patients (22 male, 6 female, mean age 50±8.0) with angiographicalfy-proyen slow coronary flow at one or more coronary arterieswere included in study. All drugs that may interact with'endothelial functions were stopped 15 days before the study. At the end of 15 days, baseline brachial artery Doppler'exairiinations were performed and diprydamole 75 mg tid. was given to all patients during the nex tone month, and at the end of one month, brachial artery Doppler examinations were reperformed.Results: When the results of the patients before and after use of diprydamole were compared, it was observed that * post-diprydamole flow mediated vasodilatation (FMD) value was significantly higher than the basal FMD value (FMD-prediprydamole: 2.7%±1.9, FMD-postdiprydamole: 3.1%±1.8, p=0.001). Nitroglyserine (NTG), thus shows . endothelium-independent vasodilatation, showed no significant, difference in prediprydamole and postdiprydamole period (NTG-prediprydamole: 13.1%±3.3, NTG-postdiprydamole: 13.0%±3.0, p=0.9). It was also noted that mean corrected TIMI frame count showed strong but inverse relationship with baseline F1VÎD percent (r—0.26, p

Özet

Amaç: Yavaş koroner akım (YKA), anjiyografık olarak belirgin koroneir arter hastalığı1 yokluğunda, Thrombolysis in Myocardial Infarction (TIMI)-2 akımın izlendiği farkı bir anjiyografik bulğu olup patofizyolojisi ile ilgili olarak endotel ve mikrovasküler disfonksiyon üzerinde durulmaktadır. Önceki çalışmalarda oral başlanan: dipridamolün-anjiyografik olarak YKA'ı düzelttiği gösterilmiştir. Bu çalışmanın amacı;fizyopatolojisinde endotel disfonksiyonunun düşünüldüğü YKA'da, dipridamolün endotel fonksiyonları üzerine olan etkisini değerlendirmektir. Gereç ve yöntem: Çalışmaya anjiyografık olarak bir veya daha fazla koroner arterinde yavaş akımın tespit edildiği, 28 hasta (ortalama yaşları 50 ± 8.0 olan 22 erkek 6 kadın) alındı. Çalışmaya katılan hastalarda endotel fonksiyonlarını , etkileyebilecek olan ilaçlar 15 gün öncesinden kesildi. 15. gün sonunda bazal brakiyal arter Doppler incelemesi , yapıldıktan sonra hastalara 1 ay süre ile 75 mg dipridamol günde 3 defa verildi ve 1. ay sonunda brakiyal arter Doppler incelemesi tekrarlandı. Bulgular: Hastaların dipridamol öncesi ve sonrası değerleri karşılaştırıldığında bazal akım aracılı vazodilatasyon (AAD) % değerine göre dipridamol sonrası bakılan % AAD değerinde anlamlı artış izlendi (AAD dipridamol öncesi: %2.7±1.9, AAD dipridamol sonrası; %3.:1 + 1:8, p=0.001). Nitrogliserin (N.TG), yani endotel bağımsız dilatasyonda , dipridamol öncesi ve: sonrası açısından, farklılık, tespit edilmedi (NTG dipiridamo] öncesi: %13.1 ±3.3, NTG dipiridamol sonrası: %13.0±3.0, p=0.9). Ortalama, düzeltilmiş TIMI frame sayısının bazal-AAD yüzdesi ile güçlü fakat : ters bir ilişkigösterdiği belirlendi. (r=-0.26, p
