Thrombo-Inflammation in Cardiovascular Disease
2020
AbstractThrombo-inflammation describes the complex interplay between blood coagulation and inflammation that plays a critical role in cardiovascular diseases. The third Maastricht Consensus Conference on Thrombosis assembled basic, translational, and clinical scientists to discuss the origin and potential consequences of thrombo-inflammation in the etiology, diagnostics, and management of patients with cardiovascular disease, including myocardial infarction, stroke, and peripheral artery disease. This article presents a state-of-the-art reflection of expert opinions and consensus recommendations regarding the following topics: (1) challenges of the endothelial cell barrier; (2) circulating …
Relationship between olive oil consumption and ankle-brachial pressure index in a population at high cardiovascular risk.
2020
[Background and aims]: The aim of this study was to ascertain the association between the consumption of different categories of edible olive oils (virgin olive oils and olive oil) and olive pomace oil and ankle-brachial pressure index (ABI) in participants in the PREDIMED-Plus study, a trial of lifestyle modification for weight and cardiovascular event reduction in individuals with overweight/obesity harboring the metabolic syndrome.
Vitamin D and Cardiovascular Health
2021
The principal source of vitamin D in humans is its biosynthesis in the skin through a chemical reaction dependent on sun exposure. In lesser amounts, the vitamin can be obtained from the diet, mostly from fatty fish, fish liver oil and mushrooms. Individuals with vitamin D deficiency, defined as a serum level of 25 hydroxyvitamin D < 20 ng/dl, should be supplemented. Vitamin D deficiency is a prevalent global problem caused mainly by low exposure to sunlight. The main role of 1,25 dihydroxyvitamin D is the maintenance of calcium and phosphorus homeostasis. However, vitamin D receptors are found in most human cells and tissues, indicating many extra-skeletal effects of the vitamin, particula…
Human-based evidence for the therapeutic potential of arginase inhibitors in cardiovascular diseases
2020
Arginase is a ubiquitous enzyme that regulates polyamine- and nitric-oxide-requiring vascular functions. It is well-established that, in mammals, arginase overactivation contributes to endothelial dysfunction, a hallmark of cardiovascular diseases. The pharmacological potential of arginase inhibition for improving vascular function is largely supported by a wide range of data from animal studies. However, caution is required before extrapolating animal data to humans because interspecies differences in arginase expression and localization have been observed. For this reason, this review presents the existing arguments from human data in favor of a role of arginase in cardiovascular diseases…
7-ketocholesterol and 7β-hydroxycholesterol: in vitro and animal models used to characterize their activities and to identify molecules preventing th…
2020
International audience; Oxysterols are molecules derived by the oxidation of cholesterol and can be formed either by auto-oxidation, enzymatically or by both processes. Among the oxysterols formed by auto-oxidation, 7-ketocholesterol and 7beta-hydroxycholesterol are the main forms generated. These oxysterols, formed endogenously and brought in large quantities by certain foods, have major cytotoxic properties. They are powerful inducers of oxidative stress, inducing dysfunction of organelles (mitochondria, lysosomes and peroxisomes) that can cause cell death. These molecules are often identified in increased amounts in common pathological states such as cardiovascular diseases, certain eye …
Mediterranean Diet Improves High-Density Lipoprotein Function in High-Cardiovascular-Risk Individuals: A Randomized Controlled Trial.
2017
Background: The biological functions of high-density lipoproteins (HDLs) contribute to explaining the cardioprotective role of the lipoprotein beyond quantitative HDL cholesterol levels. A few small-scale interventions with a single antioxidant have improved some HDL functions. However, to date, no long-term, large-scale, randomized controlled trial has been conducted to assess the effects of an antioxidant-rich dietary pattern (such as a traditional Mediterranean diet [TMD]) on HDL function in humans. Methods: This study was performed in a random subsample of volunteers from the PREDIMED Study (Prevención con Dieta Mediterránea; n=296) after a 1-year intervention. We compared the effects …
Statins in liver disease: not only prevention of cardiovascular events
2018
Statins are lipid-lowering agents and one of the most pre-scribed drugs worldwide. Their main mechanism of action –inhibition of the mevalonate pathway through an effect on hydroxy-methylglutaryl CoA reductase, thus affecting the synthesis of cholesterol in the liver – makes this class of drugs pivotal in primary and secondary prevention of cardio-vascular risk, as extensively demonstrated in large prospective, randomized controlled trials. Along the years, we learned that the lower the better, and LDL-cholesterol targets have been progressively reduced to values ≤70 mg/dL for secondary prevention or in the presence of diabetes.
Can we prevent and modify cardiometabolic disorders by controlling HCV infection?
2017
HCV infection has an estimated global prevalence of 1.0%, corresponding to roughly 71.1 million of infected individuals in 2015, with major geographical heterogeneity.1 Due to the large burden of infected individuals in the general population, the likelihood of co-occurrence of chronic HCV infection and common comorbidities is substantial regardless of causal linkages. Population-based studies show a higher overall mortality, both for liver-related and unrelated causes in HCV infected subjects compared with those uninfected, and cross-sectional and cohort studies identify HCV as an independent risk factor for extrahepatic manifestations.2 These issues are summarised in two meta-analyses rep…
Do urocortins have a role in treating cardiovascular disease?
2018
Corticotropin-releasing factor (CRF) and the three homolog neuropeptides, urocortin (UCN) 1, 2 and 3, are the major neuroendocrine factors implicated in the response of the body to stress. Recent evidence suggests that UCNs have a significant role in the pathogenesis and management of cardiovascular disease, such as congestive heart failure, ischemic heart disease, and hypertension. These data led to the initiation of clinical trials testing a possible role of UCNs in the diagnosis and therapy of cardiovascular disease, with encouraging results. Here, we summarize the available literature concerning the role of UCNs in the cardiovascular system, focusing on the emerging data creating a pote…
Cardiovascular outcomes trials with incretin-based medications: a critical review of data available on GLP-1 receptor agonists and DPP-4 inhibitors
2020
Glucagon-like peptide-1 receptor agonists (GLP-1RAs) and dipeptidyl peptidase-4 (DPP-4) inhibitors are so called “incretin-based therapies” (IBTs) that represent innovative therapeutic approaches and are commonly used in clinical practice for the treatment of type 2 diabetes mellitus (T2DM). The cardiovascular outcome trials (CVOTs) have provided useful information that has helped to shape changes in clinical practice guidelines for the management of T2DM. At the same time, the mechanisms that may explain the nonglycemic and cardiovascular (CV) benefits of these medications are still being explored. A summary of the main findings from CVOTs performed to-date with particular emphasis on vari…
