Endothelial dysfunction and carotid lesions are strong predictors of clinical events in patients with early stages of atherosclerosis: a 24-month fol…
2008
Background The purpose of this study was to investigate whether the vasodilator response to brachial artery and the presence of carotid lesions may have a prognostic significance in patients with early stages of atherosclerosis. Methods and results Vascular echography was performed to analyze flow-mediated vasodilatation (FMD) at the brachial artery and intima–media thickness (IMT) of carotid arteries in 84 asymptomatic patients. At baseline, we evaluated all the established traditional cardiovascular risk factors. Transient ischemic attack, stroke, effort or unstable angina, acute myocardial infarction, peripheral arterial disease and cerebrovascular and cardiovascular death served as outc…
PREDICTION OF CEREBROVASCULAR AND CARDIOVASCULAR EVENTS IN PATIENTS WITH SUBLINICAL CAROTID ATHEROSCLEROSIS: THE ROLE OF C-REACTIVE PROTEIN
2008
Background Several studies have suggested that inflammation and infection may be important for accelerated progression of atherosclerosis, but few data are available on subjects with early stages of atherosclerosis. Methods and Results We included, in a prospective 5-year follow-up study, 150 patients with subclinical carotid atherosclerosis, evaluating at baseline all established traditional cardiovascular risk factors (eg, older age, male sex, obesity, hypertension, diabetes, smoking, family history of coronary artery disease, and dyslipidemia); 2 markers of inflammation, fibrinogen, and high-sensitivity C-reactive protein (CRP); and the seropositivity to Helicobacter pylori, Chlamydia pn…
Metabolic syndrome (MetS) predicts cardio and cerebrovascular events in a twenty years follow-up. A prospective study.
2012
BACKGROUND AND PURPOSE: Metabolic syndrome (MetS) is a cluster of cardiovascular risk factors, considered as emerging and promoting atherosclerosis. This study aimed at the evaluation of the influence of MetS on the prediction of cerebro and cardiovascular events during a 20 years follow-up period in an asymptomatic population of middle-aged subjects. METHODS: We evaluated 529 asymptomatic persons through a prospective study. Study population was divided into two subgroups: patients with and without MetS. Echo-color-Doppler was used in order to assess the presence of subclinical atherosclerosis. A 20 years follow-up study was carried out in order to estimate the incidence of cerebro and car…
Electrocardiographic abnormalities, preclinical carotid atherosclerosis and cardiovascular risk in an apparently healthy real-world population. Data …
2021
Background: Cardiovascular diseases (CVDs) represent important causes of morbidity and mortality. Our study aimed to evaluate cardiovascular risk using the EuroSCORE, ECG and carotid ultrasound for prevention purpose in a population of companions aged 50-70 years, asymptomatic and without CVD. Methods: History of CVD, risk factors (RF), ECG and carotid ultrasound were evaluated. Intima-media thickness (IMT) was defined as wall thickness >0.9 mm, while focal thickening ≥1.5 mm protruding into the lumen as asymptomatic carotid plaque (ACP). Results: Totally, 1860 subjects were screened. 393 (21.1%) had no RF, 780 (42%) hypertension, 571 (30.7%) hypercholesterolemia, 557 (29.9%) diabetes, 4…
Carotid Atherosclerosis Evolution When Targeting a Low-Density Lipoprotein Cholesterol Concentration70 mg/dL After an Ischemic Stroke of Atherosclero…
2020
Background: The TST trial (Treat Stroke to Target) showed the benefit of targeting a low-density lipoprotein cholesterol (LDL-C) concentration of <70 mg/dL in terms of reducing the risk of major cardiovascular events in 2860 patients with ischemic stroke with atherosclerotic stenosis of cerebral vasculature. The impact on carotid atherosclerosis evolution is not known. Methods: TST-PLUS (Treat Stroke to Target–Plaque Ultrasound Study) included 201 patients assigned to an LDL-C concentration of <70 mg/dL and 212 patients assigned to a target of 100±10 mg/dL. To achieve these goals, investigators used the statin and dosage of their choice and added ezetimibe as needed. Ultrasonographer…
Prediction of cardiovascular events with traditional risk equations and total plaque area of carotid atherosclerosis
2021
Abstract A large number of cardiovascular events occur in seemingly healthy individuals. Atherosclerosis imaging can improve the outcome and treatment regime of such subjects. We aim to assess the predictive value of atherosclerosis imaging beyond traditional risk calculators in subjects aged 40–65 years. We compared PROCAM, SCORE and FRAM with carotid ultrasound (total plaque area, TPA) and arterial age (AA) was calculated in subjects without known cardiovascular diseases. Follow-up was obtained by phone or mail. In 2842 subjects (age 50 ± 8, 38% women) 154 (5.4%) cardiovascular events occurred (ASCVD: 41 myocardial infarctions, 16 strokes or TIA, 21 CABG, 41 PTCA, 35 coronary artery disea…
Necessary Catheter Diameters for Mechanical Thrombectomy with ADAPT
2017
BACKGROUND AND PURPOSE: Large-bore catheters allow mechanical thrombectomy in ischemic stroke by engaging and retrieving clots without additional devices (direct aspiration first-pass technique [ADAPT]). The purpose of this study was to establish a model for minimal catheter diameters needed for ADAPT. MATERIALS AND METHODS: We established a theoretic model for the calculation of minimal catheter diameters needed for ADAPT. We then verified its validity in 28 ADAPT maneuvers in a porcine in vivo model. To account for different mechanical thrombectomy techniques, we factored in ADAPT with/without a hypothetic 0.021-inch microcatheter or 0.014-inch microwire inside the lumen of the aspiration…
CNS manifestations of Fabry's disease
2006
Summary Background Fabry's disease is a rare hereditary lysosomal storage disease with multiorgan involvement. Deficiency of α-galactosidase A activity leads to accumulation of neutral glycosphingolipids, especially in vascular endothelial and smooth-muscle cells. Along with progressive renal and cardiac dysfunction, stroke is a major and often life-threatening burden of the disease. Cerebral vasculopathy, confirmed by neuropathological, neuroradiological, and functional studies, occurs commonly and leads to ischaemic cerebrovascular events at an early age. Recent developments Fabry's disease is an X-linked disease and women have been regarded as only mildly affected carriers. However, rese…
Anaesthetic-related neuroprotection: intravenous or inhalational agents?
2010
In designing the anaesthetic plan for patients undergoing surgery, the choice of anaesthetic agent may often appear irrelevant and the best results obtained by the use of a technique or a drug with which the anaesthesia care provider is familiar. Nevertheless, in those surgical procedures (cardiopulmonary bypass, carotid surgery and cerebral aneurysm surgery) and clinical situations (subarachnoid haemorrhage, stroke, brain trauma and postcardiac arrest resuscitation) where protecting the CNS is a priority, the choice of anaesthetic drug assumes a fundamental role. Treating patients with a neuroprotective agent may be a consideration in improving overall neurological outcome. Therefore, a cl…
Semaphorin 6A Improves Functional Recovery in Conjunction with Motor Training after Cerebral Ischemia
2010
Stroke is a major health problem in industrialized societies. Despite numerous attempts at developing acute stroke therapies aimed at minimizing acute infarct development, the only approved therapy so far is recombinant tissue plasminogen activator (rtPA). In recent years, the attention of the stroke community has therefore also put increased emphasis on understanding processes of post-stroke recovery, and their potential exploitability for therapeutic purposes. The brain has a remarkable ability to adapt to changes after stroke. Mechanisms that contribute to this plasticity are re-mapping and expansion of cortical areas to neighboring regions of functional motor cortex areas after injury […
