Vulnerable plaque generally contains a thin fibrous cap, lipid pools, and reduced internal plaque collagen. Arterial fluorescence analysis can differentiate atherosclerotic lesions from normal arteries; however, the contribution of the lipid core to atherosclerotic arterial fluorescence remains controversial. This study aimed to identify lipid core fluorophores and to differentiate the lipid co...

our aim was to report techniques and our experience in one-stage angioplasty and stenting of ostium of left common carotid and left internal carotid arteries in an octogenarian man with transient ischemic attack, who was completely recovered from neurologic insults short time after the procedure. an 81-year-old man presented with a transient ischemic attack. neurologic examination showed left s...

Abstract Background The relationship between carotid artery ultrasound findings and clinical outcomes in percutaneous coronary intervention (PCI) patients has not been fully elucidated. Purpose To investigate the cardiovascular risks PCI patients. Methods This was a single-center retrospective study investigating 691 who underwent testing. Maximum intima-media thickness (CIMT) defined as greate...

Objectives: The objective of this case report was to determine radioopacities of the cervical region on panoramic radiographs using doppler ultrasound. Methods: 3 patients with radio-opacities of the cervical region on digital panoramic radiographs were referred to doppler ultrasound for further diagnosis. Results: In 2 cases carotid artery calcifications were identified as an irregular radio-o...

Intravascular ultrasound may be useful for studying the natural history of atherosclerotic lesions of different morphologies and for guiding interventional strategies. This study was designed to test the hypothesis that tissue appearance by intravascular ultrasound is related to the biomechanical properties of atheroma components. Forty-three atheroma caps were obtained from the abdominal aorta...

In this work, we analyse the influence of parameters a mathematical model, previously proposed by authors, for reproducing atheroma plaque in arteries. The model uses Navier–Stokes equations to calculate blood flow along lumen transient mode. It also Darcy’s law, Kedem–Katchalsky equations, and three-pore simulate plasma substance flows across endothelium. behaviours all substances arterial wal...

OBJECTIVES Afro-Caribbean subjects have a higher prevalence of hypertension, a lower prevalence of ischaemic heart disease and a higher premature mortality compared to White Europeans. Left ventricular hypertrophy (LVH) is also more prevalent in Afro-Caribbeans even at similar levels of blood pressure. It is widely believed that carotid artery intima-media thickening (IMT) represents an early m...
