Vascularized Carotid Atherosclerotic Plaque Models for the Validation of Novel Methods of Quantifying Intra-Plaque Neovascularization.

J Am Soc Echocardiogr 2021 Jun 12. Epub 2021 Jun 12.

Department of Biomedical and Molecular Sciences, Queen's University, Kingston, Canada;; Department of Medicine, Cardiovascular Imaging Network at Queen's (CINQ), Queen's University, Canada. Electronic address:

Background: Intraplaque neovascularization (IPN) in advanced lesions of the carotid artery has been linked to plaque progression and risk of rupture. Quantitative measurement of IPN may provide a more powerful tool for the detection of such "vulnerable" plaque than the current visual scoring grading method. The aim of this study was to develop a phantom platform of a neovascularized atherosclerotic plaque within a carotid artery to assess new methods of quantifying IPN. Read More

Symptomatic internal carotid artery dissection and kinking in a patient with fibromuscular dysplasia.

J Vasc Bras 2021 May 31;20:e20200243. Epub 2021 May 31.

"Vita - Salute" University, Scientific Institute H. San Raffaele, Milan, Italy.

Isolated dissection of the internal carotid artery (ICA) is rare in young patients and is a cause for strong suspicion of fibromuscular dysplasia (FMD), especially when associated with artery elongation and tortuosity. The natural history of cerebrovascular FMD is unknown and management of symptomatic patients can be challenging. We report the case of a 44-year-old female patient with a history of transient ischemic attack in the absence of cardiovascular risk factors, associated with an isolated left ICA dissection and kinking.

Coherent Plane Wave Compounding Combined with Tensor Completion Applied for Ultrafast Imaging.

IEEE Trans Ultrason Ferroelectr Freq Control 2021 Jun 8;PP. Epub 2021 Jun 8.

To solve the problem of resolution and contrast in plane wave imaging (PWI), coherent plane wave compounding (CPWC) was introduced, in which scanning was performed at different angles, which can achieve the desired image quality by combining the images obtained from PWI at different angles. However, the application of this idea reduces the frame rate in proportion to the number of plane waves (PW) or angles, so that in this modality, when dealing with some applications such as shear wave imaging (SWI) and strain imaging, there is always a compromise between the frame rate and the image quality. Tensor completion (TC) is a powerful technique to recover missing information of a low-rank tensor from limited observations based on rank minimization. Read More

Hemodynamic arterial changes in heart failure: a proposed new paradigm of "Heart and Vessels Failure (HVF)".

Minerva Cardiol Angiol 2021 Jun 8. Epub 2021 Jun 8.

Heart Failure Unit and Division of Cardiology, Cardiothoracic and Vascular Department, San Raffaele Hospital and Scientific Institute (IRCCS), Milan, Italy.

Background: Although heart failure (HF) is one of the most common conditions affecting the heart, little attention has been placed on the role of arteries in contributing to the progression of this disease. We sought to determine the hemodynamic change of arteries in HF patients subdivided according to left ventricular ejection fraction. The major goal was to establish the active compensatory role of arteries in HF. Read More

Age and Interleukin-15 Levels Are Independently Associated With Intima-Media Thickness in Obesity-Related NAFLD Patients.

Front Med (Lausanne) 2021 21;8:634962. Epub 2021 May 21.

Clinical Pharmacology Consultant, Casoria, Italy.

Common carotid intima-media thickness (IMT) represents a functional and structural marker of early, precocious, and subclinical atherosclerosis, independently from the carotid plaque. Macrophage cells, which have been detected in adipose tissue and atherosclerotic plaques, are regulated by interleukin-15 (IL-15). At the light of the conflicting results concerning the role of IL-15 in atherosclerosis, the aim of the study was to retrospectively evaluate in a population of 80 obese patients, with median age of 46 years (IQR 34-53 years), with a low rate of comorbidities but with non-alcoholic fatty liver disease (NAFLD) or hepatic steatosis (HS), the relationship between IMT and serum concentrations of IL-15.

Refractory vasospastic angina in a patient with fibromuscular dysplasia: A case report.

J Cardiol Cases 2021 Jun 26;23(6):261-263. Epub 2020 Dec 26.

Division of Cardiology, Department of Medicine, University of Verona, Verona, Italy.

A 49-year-old woman affected by fibromuscular dysplasia (FMD) of the carotid artery with recurrent coronary vasospasm, refractory to medical therapy was admitted for anginal pain. Coronary involvement related to FMD is uncommon and its diagnosis "in vivo" still represents a challenge. Although a clear association between FMD and spontaneous coronary artery dissections is described, the presentation as severe coronary vasospasm is rare and it is associated with unfavorable outcome, especially when treated by means of percutaneous coronary intervention.

Disease activity influences the reclassification of rheumatoid arthritis into very high cardiovascular risk.

Arthritis Res Ther 2021 Jun 4;23(1):162. Epub 2021 Jun 4.

Epidemiology, Genetics and Atherosclerosis Research Group on Systemic Inflammatory Diseases, Hospital Universitario Marqués de Valdecilla, IDIVAL, Santander, Spain.

Background: Previous studies have shown that risk chart algorithms, such as the Systematic Coronary Risk Assessment (SCORE), often underestimate the actual cardiovascular (CV) risk of patients with rheumatoid arthritis (RA). In contrast, carotid ultrasound was found to be useful to identify RA patients at high CV. In the present study, we aimed to determine if specific disease features influence the CV risk reclassification of RA patients assessed by SCORE risk charts and carotid ultrasound. Read More

Predictors for carotid and femoral artery intima-media thickness in a non-diabetic sleep clinic cohort.

PLoS One 2021 4;16(6):e0252569. Epub 2021 Jun 4.

Ludwig Engel Centre for Respiratory Research, The Westmead Institute for Medical Research, Westmead, Sydney, New South Wales, Australia.

Introduction: The impact of sleep disordered breathing (SDB) on arterial intima-media thickness (IMT), a surrogate measure for cardiovascular disease, remains uncertain, in part because of the potential for non-SDB vascular risk factor interactions. In the present study, we determined predictors for common carotid (CCA) and femoral (CFA) artery IMT in an adult, sleep clinic cohort where non-SDB vascular risk factors (particularly diabetes) were eliminated or controlled.

Methods: We recruited 296 participants for polysomnography (standard SDB severity metrics) and CCA/CFA ultrasound examinations, followed by a 12 month vascular risk factor minimisation (RFM) and continuous positive pressure (CPAP) intervention for participants with a range of SDB severity (RFM Sub-Group, n = 157; apnea hyponea index [AHI]: 14.
