Abstract

Objective: The histological characteristics of plaque may affect the hemodynamic outcome of a given coronary stenosis. In particular, the potential effect of volumetric calcium content and the topographical distribution in the lesion segment on physiological outcome has not yet been investigated. The aim of this study was to identify any potential correlation between patterns of calcification and the fractional flow reserve (FFR) and the coronary remodeling index (RMI).Methods: A total of 26 stable angina pectoris and 34 acute coronary syndrome patients without persistent ST-segment elevation constituted the study population. FFR was used to assess 70 intermediate coronary stenosis lesions. After obtaining hemodynamic measurements, quantitative grayscale and virtual histology-intravascular ultrasound analyses were performed. The depth, length, and circumferential distribution of calcification of the lesions were also recorded.Results: Within the analyzed segment (area of interest, lesion segment), FFR was correlated with maximal thickness of deep calcification (r=-0.285; p=0.021) and calcification angle (r=-0.396; p=0.001). In lesions with a calcification angle >180°, the mean FFR value was significantly lower compared with those

Özet

Amaç: Histolojik plak özellikleri koroner darlıklarının yol açtığı hemodinamik sonuçları etkileyebilmektedir. Kalsiyumun topografik dağılımının koroner darlıklarının yol açtığı fizyolojik sonuçları nasıl etkilediği konusunda henüz bilimsel araştırma yapılmadı. Bu çalışma fraksiyonel akım rezervi (FAR) ile kalsifikasyon paternleri arasındaki olası ilişkiyi ortaya koymayı hedeflemektedir. Ayrıca, kalsifikasyon şekillerinin koroner yeniden şekillenmesi üzerindeki etkisi de araştırılmaktadır.Yöntemler: Kararlı angina pektorisli 26 ve kalıcı ST yükselmesiz akut koroner sendromlu 34 hasta bu çalışmaya dahil edildi. Orta derece (gözle %50 ile %80 arası darlığa sahip olduğu değerlendirilen) 70 lezyon FAR ile değerlendirildi. Hemodinamik ölçümler alındıktan sonra damar içi ultrason ile gri skala ve gerçek histolojik parametreler en küçük lümen alanı ve tüm lezyon için değerlendirildi. Lezyonlar kalsifikasyonun derinliği, uzunluğu ve dairesel dağılımına göre sınıflandırıldı.Bulgular: Analiz edilen segmentte, FAR ile en yüksek derin kalsifikasyon açısı (r=-0.396, p=0.001) ve kalınlığı (r=-0.285, p=0.021) arasında korelasyon saptandı. Kalsifikasyon açısı 180 dereceden geniş olanlarda ortalama FAR değerinin anlamlı derecede daha düşük olduğu tespit edildi (0.64±0.17 ve 0.78±0.08, p=0.024). Koroner yeniden şekillenmesi ile en yüksek yüzeysel (r=-0.437, p
