Abstract

Background Despite series of endovascular recanalization of chronically occluded ICA (COICA) have been already reported, technical aspects of this strategy were not described. We discussed technical details and feasibility of this strategy. Clinical presentation Five COICA (C1-cavernous ICA) patients presenting symptomatic hypoperfusion were recanalized with multiple coronary and carotid stents. All patients experienced long-term reperfusion with resolution of the clinical symptoms. Conclusion Endovascular revascularization of COICA appears feasible and associated with improvement of the hypoperfusion.

Abstract

BACKGROUND: Patients with peripheral artery disease have an increased risk of cardiovascular morbidity and mortality. Antiplatelet agents are widely used to reduce these complications.METHODS: This was a multicentre, double-blind, randomised placebo-controlled trial for which patients were recruited at 602 hospitals, clinics, or community practices from 33 countries across six continents. Eligible patients had a history of peripheral artery disease of the lower extremities (previous peripheral bypass surgery or angioplasty, limb or foot amputation, intermittent claudication with objective evidence of peripheral artery disease), of the carotid arteries (previous carotid artery revascularisation or asymptomatic carotid artery stenosis of at least 50%), or coronary artery disease with an ankle-brachial index of less than 0·90. After a 30-day run-in period, patients were randomly assigned (1:1:1) to receive oral rivaroxaban (2·5 mg twice a day) plus aspirin (100 mg once a day), rivaroxaban twice a day (5 mg with aspirin placebo once a day), or to aspirin once a day (100 mg and rivaroxaban placebo twice a day). Randomisation was computer generated. Each treatment group was double dummy, and the patient, investigators, and central study staff were masked to treatment allocation. The primary outcome was cardiovascular death, myocardial infarction or stroke; the primary peripheral artery disease outcome was major adverse limb events including major amputation. This trial is registered with ClinicalTrials.gov, number NCT01776424, and is closed to new participants.FINDINGS: Between March 12, 2013, and May 10, 2016, we enrolled 7470 patients with peripheral artery disease from 558 centres. The combination of rivaroxaban plus aspirin compared with aspirin alone reduced the composite endpoint of cardiovascular death, myocardial infarction, or stroke (126 [5%] of 2492 vs 174 [7%] of 2504; hazard ratio [HR] 0·72, 95% CI 0·57-0·90, p=0·0047), and major adverse limb events including major amputation (32 [1%] vs 60 [2%]; HR 0·54 95% CI 0·35-0·82, p=0·0037). Rivaroxaban 5 mg twice a day compared with aspirin alone did not significantly reduce the composite endpoint (149 [6%] of 2474 vs 174 [7%] of 2504; HR 0·86, 95% CI 0·69-1·08, p=0·19), but reduced major adverse limb events including major amputation (40 [2%] vs 60 [2%]; HR 0·67, 95% CI 0·45-1·00, p=0·05). The median duration of treatment was 21 months. The use of the rivaroxaban plus aspirin combination increased major bleeding compared with the aspirin alone group (77 [3%] of 2492 vs 48 [2%] of 2504; HR 1·61, 95% CI 1·12-2·31, p=0·0089), which was mainly gastrointestinal. Similarly, major bleeding occurred in 79 (3%) of 2474 patients with rivaroxaban 5 mg, and in 48 (2%) of 2504 in the aspirin alone group (HR 1·68, 95% CI 1·17-2·40; p=0·0043).INTERPRETATION: Low-dose rivaroxaban taken twice a day plus aspirin once a day reduced major adverse cardiovascular and limb events when compared with aspirin alone. Although major bleeding was increased, fatal or critical organ bleeding was not. This combination therapy represents an important advance in the management of patients with peripheral artery disease. Rivaroxaban alone did not significantly reduce major adverse cardiovascular events compared with asprin alone, but reduced major adverse limb events and increased major bleeding.FUNDING: Bayer AG.

Abstract

PurposeTo evaluate the occurrence and risk factors of acute in-stent thrombosis or stent occlusion in patients with tandem occlusions receiving intracranial mechanical thrombectomy and emergent extracranial internal carotid artery stenting with a dual layer carotid stent.MethodsMulticenter retrospective data collection and analysis of stroke databases of seven comprehensive stroke centers from three European countries.ResultsOverall, 160 patients (mean (SD) age 66 (12) years; 104 men (65%); median (IQR) baseline NIHSS 14 (9–18); IV lysis, n=97 (60.6%)) were treated for a cervical carotid artery occlusion or stenosis using a CASPER stent (MicroVention), and received mechanical thrombectomy for an intracranial occlusion between April 2014 and November 2018. During the procedure or within 72 hours, formation of thrombus and complete occlusion of the CASPER stent was observed in 33/160 (20.8%) and in 12/160 patients (7.5%), respectively. In 25/33 (75.8%) and in 9/12 patients (75%), respectively, this occurred during the procedure. No statistically significant difference was observed between patients with and without thrombus formation with regard to pre-existing long term medication with anticoagulants or intraprocedural administration of heparin, acetylsalicylic acid (ASA), or heparin and ASA. Favorable early neurological outcome was similar in patients with (n=15; 45.5%) and without (n=63; 49.6%) thrombus formation at the CASPER stent.ConclusionAcute thrombosis or occlusion of CASPER stents in thrombectomy patients receiving emergent extracranial internal carotid artery stenting for tandem occlusions were observed more often during the procedure than within 72 hours of follow-up, were less frequent then previously reported, and showed no impact on early neurological outcome.

Abstract

International audience; OBJECTIVES: To gain insight into early mechanisms of aortic widening, we examined associations between the diameter of the abdominal aorta (AD) and cardiovascular disease (CVD) risk factors and biomarkers, as well as measures of subclinical atherosclerosis, in a multi-ethnic population. DESIGN: Cross-sectional cohort. METHODS: A total of 1926 participants (mean age 62, 50% women) underwent chest and abdomen scanning by computed tomography, ultrasound of the carotid arteries, and CVD risk factor assessment. AD was measured 5 cm above and at the bifurcation. RESULTS: In a model containing traditional CVD risk factors, biomarkers and ethnicity, only age (standardized β = 0.97), male sex (β = 1.88), body surface area (standardized β = 0.92), current smoking (β = 0.42), D-dimer levels (β = 0.19) and hypertension (β = 0.53) were independently and significantly associated with increasing AD (in mm) at the bifurcation; use of cholesterol-lowering medications predicted smaller AD (β = -0.70) (P < 0.01 for all). These findings were similar for AD 5 cm above the bifurcation with one exception: compared to Caucasian-Americans, Americans of Chinese, African and Hispanic descent had significantly smaller AD 5 cm above the bifurcation (β's = -0.59, -0.49, and -0.52, respectively, all P < 0.01), whereas AD at the bifurcation did not differ by ethnicity. Physical activity, alcohol consumption, diabetes and levels of IL-6, CRP and homocysteine were not independently associated with AD. Higher aortic and coronary artery calcium burden, but not common carotid artery intima-media thickness, were independently, but modestly (β = 0.11 to 0.19), associated with larger AD. CONCLUSIONS: Incremental widening of the aortic diameter shared some, but not all, risk factors for occlusive vascular disease.

Abstract

Background and Purpose— The association of carotid atherosclerosis with body composition and fat distribution is poorly understood. We aimed to test the cross-sectional association of carotid plaques and common carotid artery intima-media thickness with calf circumference (CC), representing peripheral fat and lean mass, and with waist circumference and waist-to-hip ratio, 2 markers of abdominal obesity. Methods— The study was performed on 6265 subjects aged ≥65 years recruited prospectively from the electoral rolls of 3 French cities. Ultrasound examination and anthropometric measures were performed according to a standardized protocol. Results— Carotid plaques were less frequent with increasing CC, the ORs for the second, third, and fourth quartile of CC compared with the first quartile being 0.98 (95% CI, 0.84 to 1.15), 0.85 (95% CI, 0.72 to 1.01), and 0.71 (95% CI,:0.58 to 0.86; P for trend=0.0002), respectively, independently of age, gender, body mass index, and other vascular risk factors. There was an opposite and multiplicative effect of CC and waist-to-hip ratio on the frequency of carotid plaques (55.1% of individuals in the fourth waist-to-hip ratio quartile and the first CC quartile had carotid plaques, against 31.8% in the first waist-to-hip ratio and the fourth CC quartile). Mean common carotid artery intima-media thickness was larger with increasing waist circumference, waist-to-hip ratio, and CC, but the association with CC disappeared after adjusting for body mass index. Conclusion— The present study shows, for the first time, an inverse relationship between carotid plaques and CC. Although this needs to be confirmed in other populations, it may suggest an antiatherogenic effect of large CC.

Abstract

The critical role of Toll-like receptors (TLRs) in mammalian host defense has been extensively explored in recent years. The capacity of about 10 TLRs to recognize conserved patterns on many bacterial and viral pathogens is remarkable. With so few receptors, cross-reactivity with self-tissue components often occurs. Previous studies have frequently assigned detrimental roles to TLRs, in particular to TLR2 and TLR4, in immune and cardiovascular disease. Using human and murine systems, we have investigated the consequence of TLR3 signaling in vascular disease. We compared the responses of human atheroma-derived smooth muscle cells (AthSMC) and control aortic smooth muscle cells (AoSMC) to various TLR ligands. AthSMC exhibited a specific increase in TLR3 expression and TLR3-dependent functional responses. Intriguingly, exposure to dsRNA in vitro and in vivo induced increased expression of both pro- and anti-inflammatory genes in vascular cells and tissues. Therefore, we sought to assess the contribution of TLR3 signaling in vivo in mechanical and hypercholesterolemia-induced arterial injury. Surprisingly, neointima formation in a perivascular collar-induced injury model was reduced by the systemic administration of the dsRNA analog Poly(I:C) in a TLR3-dependent manner. Furthermore, genetic deletion of TLR3 dramatically enhanced the development of elastic lamina damage after collar-induced injury. Accordingly, deficiency of TLR3 accelerated the onset of atherosclerosis in hypercholesterolemic ApoE −/− mice. Collectively, our data describe a protective role for TLR signaling in the vessel wall.

Abstract

International audience; PURPOSE: The early diagnosis of traumatic internal carotid artery dissection (TICAD) is essential for initiating appropriate treatment and improving outcome. We searched for criteria from transcranial Doppler (TCD) measurements on admission that could be associated with subsequent TICAD diagnosis in patients with traumatic brain injury (TBI). METHODS: We conducted a retrospective 1:4 matched (age, mean arterial blood pressure) cohort study of 11 TBI patients with TICAD and absent or mild brain lesions on initial CT scan, 22 TBI controls with comparable brain CT scan lesions (controls 1), and 22 TBI controls with more severe brain CT scan lesions (controls 2) on admission. TCD measurements were obtained on admission from both middle cerebral arteries (MCA). All patients had subsequent CT angiography to diagnose TICAD. RESULTS: A >25% asymmetry in the systolic blood flow velocity between the two MCA was found in 9/11 patients with TICAD versus 0/22 in controls 1 and 5/22 in controls 2 (p < 0.01). The combination of this asymmetry with an ipsilateral pulsatility index < or =0.80 was found in 9/11 patients with TICAD versus none in the two groups of controls (p < 0.01). CONCLUSIONS: Our results suggest that significant asymmetry in the systolic blood flow velocity between the MCAs and a reduced ipsilateral pulsatility index could be criteria from TCD measurements associated with the occurrence of TICAD in head-injured patients. If prospectively validated, these findings could be incorporated in screening protocols for TICAD in patients with TBI.

Abstract

International audience; OBJECTIVE: Ischemic strokes represent more than 80% of total strokes in Western countries. The influence of dietary factors on ischemic stroke risk is debated mainly because available data are limited. Our objective was to compare the dietary pattern of symptomatic ischemic stroke patients under 65 years old with control subjects using a validated 14-item food frequency questionnaire (FFQ). We also compared symptomatic ischemic stroke patients with carotid atherosclerosis with those without according to the presence or the absence of carotid plaque defined by duplex scanning. METHODS: This was a case-control multi-center study that took place in one University hospital and two general hospitals in France. One hundred twenty-four symptomatic ischemic stroke patients (confirmation by a neurologist and imaging; 66% smokers) and 50 controls (34% smokers) without any known cardiovascular disease or previous nutritional advice were included. The main outcome measure(s) were intake scores for saturated (SFA), monounsaturated (MUFA), Omega-3 polyunsaturated (Omega-3 PUFA), and Omega-6 polyunsaturated fatty acids (Omega-6PUFA). Fruit and vegetables and an overall cardiovascular dietary score were evaluated with the FFQ. The overall cardiovascular score is calculated as (MUFA + Omega-3 PUFA + fruits and vegetables) - (SFA) scores. RESULTS: Compared with controls, ischemic stroke patients had a higher SFA score (6.6 +/- 3.0 vs 4.9 +/- 2.7; P < .001), lower scores of MUFA (0.8 +/- 0.9 vs 1.5 +/- 1.2; P < .001), Omega-3 PUFA (1.7 +/- 1.6 vs 2.2 +/- 1.5; P = .013), Omega-6PUFA (2.6 +/- 2.5 vs 3.9 +/- 2.7; P = .002), fruit and vegetables (2.9 +/- 1.7 vs 3.8 +/- 1.6; P = .005), and a lower overall dietary score (-1.2 +/- 5.0 vs 2.5 +/- 4.4; P < .001). These results remained statistically significant after adjustment for age, gender, and smoking status. Ischemic stroke patients with carotid atherosclerosis (n = 54) had a worse overall cardiovascular dietary score than those without (n = 68): -2.2 +/- 4.4 vs -0.2 +/- 5.2; P = .024. CONCLUSION: Compared with controls, ischemic stroke patients, especially those with carotid atherosclerosis, have an unfavorable dietary pattern (high SFA, low fruit and vegetables, and Omega-3 PUFA consumptions) that may have been a facilitating condition of the ischemic stroke. Dietary recommendations of a healthy diet should be useful in ischemic stroke prevention, especially in patients with cardiovascular risk factors.

Abstract

Objective— Arterial mechanical properties are of growing interest in the understanding of cardiovascular disease development. We aimed to determine the predictive value of carotid wall mechanics on coronary heart disease (CHD) in the Three-City study. Methods and Results— At baseline, 3337 participants aged ≥65 years underwent a carotid B-mode ultrasonography. During a median follow-up of 43.4 months, 128 CHD occurred. Increased carotid distension (relative stroke change in lumen diameter) was significantly associated with CHD risk. Comparison of subjects in tertile 3 versus those in tertile 1 (reference) showed a hazard ratio (HR) of 1.80 (95% CI, 1.17 to 2.75). Controlling for various confounders including age, heart rate, brachial (or carotid) pulse pressure, and common carotid intima-media thickness did not alter the association between carotid distension and CHD with a HR of 1.79 (95% CI, 1.12 to 2.86; tertile 3 versus tertile 1). Brachial and carotid pulse pressures were also independently associated with CHD. No association was found between CHD and carotid distensibility coefficient, cross-sectional compliance coefficient, Young’s elastic modulus, or β stiffness index. Conclusions— In the elderly, increased carotid distension was independently predictive of CHD. This simple and noninvasive parameter might be of particular interest for cardiovascular risk assessment.

Abstract

International audience; Oxidized LDLs (oxLDLs) induce apoptosis, which contributes to the pathogenesis of atherosclerosis. The 150 kDa oxygen-regulated protein (ORP150), an endoplasmic reticulum (ER)-resident chaperone, is upregulated by hypoxia and prevents ischemia-induced cell death. The aim of this work was to investigate whether and how ORP150 can prevent apoptosis induced by oxLDLs in vascular cells. OxLDLs induced ORP150 expression in the ER of human microvascular endothelial cell line (HMEC-1). ORP150 expression was blocked by antioxidants, by the permeant calcium chelator BAPTA-AM, and by inhibitors of the inositol-1,4,5 trisphosphate (IP3) receptors, 2-aminoethyl diphenylborinate (2-APB) and xestospongin C. ORP150 silencing by siRNA-enhanced oxLDL-induced apoptosis, while forced ORP150 expression increased the resistance of cells via an inhibition of the oxLDL-induced calcium rise, and of subsequent calpain activation, cytochrome c release, caspase 3 activation and apoptosis. A similar protective effect was achieved by BAPTA-AM, 2-APB and xestospongin C. Altogether, these data indicate that (i)ORP150 inhibits oxLDL-induced apoptosis by blocking calcium signaling and subsequent apoptosis, (ii)calcium released from ER stores through IP3 channels is involved in the oxLDL-induced calcium rise and apoptosis, and is inhibited by ORP150. Finally, ORP150 is expressed in advanced atherosclerotic lesions, where it may locally participate to reduce the apoptotic effect of oxLDLs and the subsequent risk of plaque rupture.

Abstract

Purpose To identify and quantify the potential sources of motion in carotid artery imaging. Materials and Methods Two healthy volunteers and 12 patients (20–75 years old) with atherosclerotic disease were scanned on a Philips Intera 1.5T system. A single-shot balanced-fast field echo (bFFE) sequence was used to acquire real-time axial views of the carotid artery wall (three images per second). A three-step acquisition protocol was performed to analyze the three types of motion (arterial pulsation, breathing, and swallowing) separately. The isocenter carotid artery motion amplitude in either the x or y direction was measured. Radial variation in the carotid lumen between the systolic and diastolic phases was analyzed. Motion frequency was reported for each patient. Results Significant motion related to arterial pulsation (amplitude = 0.27–0.93 mm, mean = 0.6, SD = 0.19), breathing (amplitude = 0.5–3.6 mm, mean = 1.56, SD = 0.99)), and swallowing (amplitude = 1.4–9.2 mm, mean = 4.7, SD = 2.4) were visualized. Conclusion Pulsation, breathing, and swallowing are sources of significant motion in the carotid artery wall. Such motion should be considered in the future to improve carotid artery image quality.

Abstract

Background and Purpose— Gait dysfunction is an important cause of disability among the elderly and may be, in part, of vascular origin. We studied the association between carotid ultrasound parameters and measures of gait and balance in subjects 65 to 85 years of age who participated in the baseline phase of the Three-City Study in the Dijon center. Methods— The study population comprised 2572 noninstitutionalized individuals. Carotid plaques and common carotid artery intima-media thickness (CCA-IMT) were measured using ultrasonography. Gait and balance measures included walking speed and a modified version of the Tinetti scale. Results— Mean maximum walking speed (MWS) decreased with increasing CCA-IMT and number of plaques ( P −4 ). Compared with subjects in the lowest CCA-IMT quintile, the odds ratio (95% CI) for being in the lowest MWS quartile was 1.1 (0.8 to 1.6) in the second, 1.3 (0.9 to 1.8) in the third, 1.7 (1.2 to 2.4) in the fourth, and 2.2 (1.6 to 3.1) in the higher CCA-IMT quintile ( P −4 ). Mean (SD) CCA-IMT was 0.716 (0.118) mm in subjects with a modified Tinetti score P =0.006). The proportion of subjects in the lowest MWS quartile ( P =0.006) or with a modified Tinetti score P =0.05) increased with the number of plaques. These relations were attenuated after adjustment for vascular risk factors. Conclusions— Carotid plaques and higher CCA-IMT values are associated with worse performances on gait and balance tests. Our results suggest that vascular factors may play an important and under-recognized role in motor function.

Abstract

Proliferation of vascular smooth muscle cells (VSMC) is a primary cause of vascular disorders and is associated with major alterations in Ca 2+ handling supported by loss of the sarco/endoplasmic reticulum calcium ATPase, SERCA2a. To determine the importance of SERCA2a in neointima formation, we have prevented loss of its expression by adenoviral gene transfer in a model of balloon injury of the rat carotid artery. Two weeks after injury, the intima/media ratio was significantly lower in SERCA2a-infected than in injured noninfected or injured β-galactosidase–infected carotids (0.29±0.04 versus 0.89±0.19 and 0.72±0.14, respectively; P

Abstract

Background: Information on the impact of hormone replacement therapy (HRT) on carotid atherosclerosis is limited. Moreover, transdermal estrogens have not been investigated. Methods: We examined association of HRT use with ultrasonographically assessed carotid atherosclerotic plaque occurrence and mean common carotid artery intima-media thickness (CCA–IMT) progression. Within the Vascular Aging (EVA) Study, a community-based cohort, 815 postmenopausal women aged 59–71 have been followed during 4 years. Among these women, 166 had already used HRT. Results: Women who had ever used HRT experienced a lower occurrence of plaques (8.6 versus 19.1%, P =0.003). After adjustment for the main cardiovascular risk factors, odds-ratio for plaque occurrence was 0.41 (95% confidence interval 0.21–0.78, P =0.01) among ever users of HRT compared with never users. When transdermal route of estrogen administration was used, adjusted odds-ratio was 0.66 (95% confidence interval 0.47–0.99, P =0.04). The progression of IMT, which was measured at a plaque-free site and adjusted on initial levels of CCA–IMT did not differ between ever and never users of HRT. It was 0.011 mm per year among ever users and 0.012 mm per year among never users ( P =0.61). Conclusion: These data suggest that HRT use may prevent the development of atherosclerotic plaques in postmenopausal women, especially when estrogens are administered by transdermal route.
