Quantitative Ultrasound Measurements of Common Carotid Artery Blood Flow Velocity Patterns in Patients with Coronary Slow Flow

Abstract

Amaç: Koroner yavaş akımlı (CSF) hastalarda karotis akım hızı (CFV) değişkenlerini analiz etmeyi amaçladık.

Yöntem Çalışmaya anjiyografi k olarak normal koroner arter yapısına sahip CSF' lu 66 hasta ve normal koroner arter ve normal kan akımına sahip

53 kontrol alındı. Koroner akım, miyokard İnfarktüsü frame Sayımı (cTFC) için düzeltilmiş tromboliz ile ölçümü ile hesaplandı. İntima

media kalınlığı (IMT) ve CFV ölçüldü. Brakiyal arter endotel bağımlı dilasyon (EDD) hesaplandı.

Bulgular IMT, pulsatilite indeksi (PI) ve direnç indeksi (RI) CSF grubunda anlamlı derecede yüksek, aksine pik sistolik hız (PSV), uç diyastolik hız

(EDV), ortalama hız (MV), çapa bağlı akımda yükselme (FMID), EDD, nitrogliserinle indüklenen dilatasyon (NID) ve hiperemi anlamlı

olarak bu grupta düşük izlendi (p < 0,001, hepsi için). Spearman korelasyon analizi karotid arter kan akım hızı paternleri ile CSF arasında

orta derecede güçlü bir ilişki olduğunu göstermiştir (p <0,05, hepsi için).

Sonuç CSF' lu hastalarda CFV azalmıştır. CSF' da olduğu gibi karotis akış hızındaki azalmanın nedenleri, endotel disfonksiyonu, mikrovasküler

direnç ve küçük damar hastalığı olabilir
