Relation Between Aortic Knob Calcium Observed by Simple Chest X-Ray or Fluoroscopy and Plaque Components in Patients With Diabetes

We used virtual histology and intravascular ultrasound (VH-IVUS) to evaluate the relation between aortic knob calcium (AKC) and plaque components in diabetic patients. The presence of AKC was assessed by posteroanterior view of chest x-ray or fluoroscopy at the time of coronary angiography. A total...

Description
Summary:We used virtual histology and intravascular ultrasound (VH-IVUS) to evaluate the relation between aortic knob calcium (AKC) and plaque components in diabetic patients. The presence of AKC was assessed by posteroanterior view of chest x-ray or fluoroscopy at the time of coronary angiography. A total of 137 de novo coronary culprit lesions in 137 consecutive diabetic patients were studied and coronary plaque components were analyzed using VH-IVUS according to the presence (n = 45) or absence (n = 92) of AKC. Patients with AKC were significantly older (68 ± 8 vs 62 ± 9 years, p
