Coronary atheroma regression and adverse cardiac events: A systematic review and meta-regression analysis.

The relationship between plaque regression induced by dyslipidemia therapies and occurrence of major adverse cardiovascular events (MACE) is controversial. We performed a systematic review and meta-regression of dyslipidemia therapy studies reporting MACE and intravascular ultrasound (IVUS) measures of change in coronary atheroma.

Novel laser-based catheter for peripheral atherectomy: 6-month results from the Eximo Medical B-Laser™ IDE study.

The B-Laser™ atherectomy system (Eximo Medical, Israel) is a 355 nm solid-state Nd:YAG short pulse laser for de-novo and restenotic infrainguinal PAD with enhanced affinity for atheroma and calcified plaque.

Retrograde aortic blood flow as a mechanism of stroke: MR evaluation of the prevalence in a population-based study.

Retrograde blood flow from complex atheroma in the descending aorta (DAo) has only recently been described as a potential mechanism of stroke. However, prevalence of this mechanism in the general population and the exact factors influencing stroke risk are unclear.

Impact of Aortic Atherosclerosis Burden on Outcomes of Surgical Aortic Valve Replacement.

Epiaortic ultrasound detects and localizes ascending aortic atherosclerosis. In this analysis we investigated the association between epiaortic ultrasound-based atheroma grade during surgical aortic valve replacement (SAVR) and perioperative adverse outcomes.

Plasma Levels of Receptor Interacting Protein Kinase-3 Correlated with Coronary Artery Disease.

Necroptosis plays an important role in human atherosclerosis and atheroma development. Since receptor interacting protein kinase-3 (RIP3) acts as a key mediator of necroptosis, this study aimed to explore its relationship between plasma RIP3 levels and coronary artery disease (CAD) and discover a potential new biomarker for screening CAD subtypes and severity.

Stage-dependent differential effects of interleukin-1 isoforms on experimental atherosclerosis.

Targeting interleukin-1 (IL-1) represents a novel therapeutic approach to atherosclerosis. CANTOS demonstrated the benefits of IL-1β neutralization in patients post-myocardial infarction with residual inflammatory risk. Yet, some mouse data have shown a prominent role of IL-1α rather than IL-1β in atherosclerosis, or even a deleterious effect of IL-1 on outward arterial remodelling in atherosclerosis-susceptible mice. To shed light on these disparate results, this study investigated the effect of neutral...

Stroke in a young man: a late complication of radiation therapy.

This 37-year-old man presented with left sided facial warmth and numbness associated with new sudden-onset right hemiparesis. The patient first developed sudden numbness of his left lip and warmth in left ear which travelled to the rest of left face. His past medical history was significant for hypertension, Hodgkin lymphoma treated with radiation therapy at the age of 10, and sleeve gastrectomy for obesity 1 year ago complicated by bilateral ischaemic cerebral infarctions with residual left hemiparesis. ...

Comparison of Rosuvastatin Versus Atorvastatin for Coronary Plaque Stabilization.

Statins are widely used to lower cholesterol and to reduce cardiovascular events. Whether all statins have similar effects on plaque stabilization is unknown. We aimed to investigate coronary plaque response to treatment with different statins that result in similar lipid reduction using serial multimodality intracoronary imaging. Patients with de novo coronary artery disease requiring intervention were randomized to rosuvastatin 10 mg (R10) or atorvastatin 20 mg (A20) daily. Optical coherence tomography an...

Curcumin as a potential modulator of M1 and M2 macrophages: new insights in atherosclerosis therapy.

Accumulation of macrophages within the artery wall is an eminent feature of atherosclerotic plaques. Macrophages are influenced by various plaque microenvironmental stimuli, such as oxidized lipids, cytokines, and senescent erythrocytes, and thereby polarize into two main phenotypes called proinflammatory M1 and anti-inflammatory M2 macrophages. In the hemorrhagic zones of atheroma, upon exposure to iron, sequestration of iron by M1 macrophages results in an uncontrolled proinflammatory phenotype impairing ...

Clinical Utility of Carotid Ultrasonography - Application for the Management of Patients with Diabetes.

Carotid ultrasonography is a noninvasive, simple, and inexpensive modality to assess the severity of atherosclerosis. This article reviews related articles, summarizes the rationale for the application of carotid ultrasonography in clinical practice, and addresses the features and the limitations of carotid ultrasonography in cardiovascular risk prediction. Numerous large studies have confirmed that various carotid ultrasound measures, such as carotid intima-media thickness (CIMT), presence or absence of ca...

Interactons of cholesterol and 7‑ketocholesterol with unsaturated fatty acids of different unsaturation degree - The monolayer study.

Unsaturated fatty acids (UFAs) are known to lower the level of sterols in blood, which accounts for their cardioprotective effect. To understand the molecular basis of this effect, Langmuir monolayer studies have been performed. A series of UFAs differing in the length of the fatty acid chain and the number of double bonds (oleic acid, OA; linoleic acid, LA; stearidonic acid, SDA; eicosanoic acid, EA) were mixed with cholesterol and its more toxic oxidized derivative, 7‑ketocholesterol (7-KC), abundantly ...

Lipid core nanoparticles as vehicle for docetaxel reduces atherosclerotic lesion, inflammation, cell death and proliferation in an atherosclerosis rabbit model.

Chemotherapeutic agents used in cancer treatment associated to nanoparticles (LDE) that mimic the composition of low-density lipoprotein and buffer their toxicity can have strong anti-atherosclerosis action, as we showed in cholesterol-fed rabbits. Here, a novel preparation of docetaxel (DTX) carried in LDE was evaluated. Eighteen rabbits were fed 1% cholesterol during 8 weeks. After the first 4 weeks, 9 animals were treated for 4 weeks with intravenous LDE-DTX (1 mg/kg/week) and 9 with LDE only (co...

DNA methyltransferase 1 and Krüppel-like factor 4 axis regulates macrophage inflammation and atherosclerosis.

Macrophage-mediated inflammatory responses occur throughout all stages of atherosclerosis. DNA methylation is one of the critical epigenetic mechanisms and is associated with the development of atherosclerosis. The underlying mechanism of epigenetic regulation of macrophage inflammation (M1 activation) remains unclear. Here we aim to study the role of DNA methyltransferase 1 (DNMT1) in modulating macrophage inflammation and atherosclerosis. DNMT1 expression is up-regulated in THP-1-derived macrophages upon ...

Down syndrome, Alzheimer disease and cerebral amyloid angiopathy: the complex triangle of brain amyloidosis.

Down syndrome (DS) is the main genetic cause of intellectual disability worldwide. The overexpression of the Amyloid Precursor Protein, present in chromosome 21, leads to β-amyloid deposition that results in Alzheimer disease (AD) and, in most cases, also to cerebral amyloid angiopathy (CAA) neuropathology. People with DS invariably develop the neuropathological hallmarks of AD at the age of 40, and they are at an ultra high risk for suffering AD-related cognitive impairment thereafter. In the general popu...

Biological function of endoecology (cleanliness of intercellular environment) realize two biolocical reactions: excretion reaction and inflammation reaction - utilization in vivo, in situ catabolites of the large molecular mass.

For the biological functions of trophology (nutrition) and homeostasis, we believe that the third place is occupied by the function of endoecology: in a single pool of intercellular environment in vivo it must be "pure". The biological function of endoecology, realizes two biological reactions: the reaction of excretion and the reaction of inflammation. The biological reaction of excretion is the filtration of phlogogens of a small mol. mass through the basement membrane of the glomerulus of the nephron and...

Keep recycling going: new approaches to reduce LDL-C.

Hypercholesterolemia represents a leading cause in the development of atherosclerotic plaques, increasing the risk for ACVS. It actually counts as a major cause of cardiovascular disease etiopathogenesis. The causes of hypercholesterolemia are multifactorial, spanning from genetic constitution, age, sex, to sedentary lifestyle and diets rich in sugars and lipids. Although dietary restriction in saturated fats, increased exercise, and other modification in lifestyle represent a first-line approach to treat v...
