Antioxidant and antiplatelet activity by polyphenol-rich nutrients: focus on extra virgin olive oil and cocoa.

Cardiovascular disease is the most common cause of death in the Western world. In the last decades nutraceutical approaches have been proposed to counteract atherosclerotic complications. In particular, polyphenols, a class of bio-active molecules prevalently contained in foods such as cocoa, fruits, vegetables, wine and tea, have been widely studied for their beneficial properties.

Relation of female sex to left atrial diameter and cardiovascular death in atrial fibrillation: The AFFIRM Trial.

Background: Female sex is associated with thromboembolism related to atrial fibrillation (AF). Left atrial (LA) diameter independently predicted incident cardiovascular (CV) major events in the general population. In AF patients, LA enlargement is associated to AF occurrence and recurrence.

Ankle-Brachial Index and cardiovascular events in atrial fibrillation. The ARAPACIS Study.

Atrial fibrillation (AF) patients are at high risk for thrombotic and vascular events related to their cardiac arrhythmia and underlying systemic atherosclerosis. Ankle-Brachial Index (ABI) is a non-invasive tool in evaluating systemic atherosclerosis, useful in predicting cardiovascular events in general population; no data are available in AF patients. ARAPACIS is a prospective multicentre observational study performed by the Italian Society of Internal Medicine, analysing association between low ABI (≤ 0.

Does Lysosomial Acid Lipase Reduction Play a Role in Adult Non-Alcoholic Fatty Liver Disease?

Lysosomal Acid Lipase (LAL) is a key enzyme involved in lipid metabolism, responsible for hydrolysing the cholesteryl esters and triglycerides. Wolman Disease represents the early onset phenotype of LAL deficiency rapidly leading to death. Cholesterol Ester Storage Disease is a late onset phenotype that occurs with fatty liver, elevated aminotransferase levels, hepatomegaly and dyslipidaemia, the latter characterized by elevated LDL-C and low HDL-C.

Antiphospholipid syndrome and anticoagulation quality: a clinical challenge.

Background And Aims: Antiphospholipid Syndrome (APS) is often complicated by ischemic vascular events. Vitamin K Antagonists (VKAs) reduce the risk of recurrent thrombosis. Quality of VKAs treatment, as assessed by the Time in Therapeutic Range (TTR), has never been investigated in APS patients.

Polypharmacy and major adverse events in atrial fibrillation: observations from the AFFIRM trial.

Background: Polypharmacy, as the use of five or more drugs, has commonly been associated with the elderly and multiple co-morbidities and related to impairment of clinical state and adverse outcomes, in general population. Limited data are available on the relationship between polypharmacy and adverse outcomes in atrial fibrillation (AF). We describe the prevalence of polypharmacy and AF, and its association with major adverse events, such as stroke and cardiovascular (CV) death.

Cardiovascular risk stratification in patients with non-valvular atrial fibrillation: the 2MACE score.

Recent findings suggest that patients with non-valvular atrial fibrillation (AF), in addition to having a high risk for ischemic stroke, are also at risk for myocardial infarction (MI). The aim of the study was to combine factors predicting Major Adverse Cardiovascular Events (MACE) in AF patients, including fatal/nonfatal MI, cardiac revascularization, and cardiovascular death, into a simple risk score. Predictors of MACE were obtained from a prospective observational cohort study, including 1019 AF patients taking vitamin K antagonists from the Atherothrombosis Center, of Sapienza University of Rome.

Urinary 11-dehydro-thromboxane B2 is associated with cardiovascular events and mortality in patients with atrial fibrillation.

Background: Patients with nonvalvular atrial fibrillation (AF) show high residual cardiovascular (CV) risk despite oral anticoagulants. Urinary 11-dehydro-thromboxane B2 (TxB2) is associated with an increased risk of CV events (CVEs), but its predictive value in patients with anticoagulated AF is unknown.

Methods: A prospective single-center cohort study, including 837 patients with AF, was conducted.

Inadequate anticoagulation by Vitamin K Antagonists is associated with Major Adverse Cardiovascular Events in patients with atrial fibrillation.

Background: Time in therapeutic range (TTR) reflects the quality of anticoagulation and is inversely correlated with ischemic stroke in atrial fibrillation (AF) patients. Few data on the relationship between TTR and myocardial infarction (MI) are available. We investigated the association between TTR and Major Adverse Cardiovascular Events (MACE) in a cohort of anticoagulated AF patients.

Circulating miR-33a and miR-33b are up-regulated in familial hypercholesterolaemia in paediatric age.

Hypercholesterolaemia is one of the major causes of CVD (cardiovascular disease). It is associated with enhanced oxidative stress, leading to increased lipid peroxidation which in turn determines endothelial dysfunction and susceptibility to coronary vasoconstriction and atherosclerosis. Different miRNAs are involved in the pathogenesis of CVD and play an important role in inflammatory process control, therefore, together with atherogenic factors, they can stimulate atherosclerotic degeneration of the vessel walls of arteries.

Frequency of Left Ventricular Hypertrophy in Non-Valvular Atrial Fibrillation.

Left ventricular hypertrophy (LVH) is significantly related to adverse clinical outcomes in patients at high risk of cardiovascular events. In patients with atrial fibrillation (AF), data on LVH, that is, prevalence and determinants, are inconsistent mainly because of different definitions and heterogeneity of study populations. We determined echocardiographic-based LVH prevalence and clinical factors independently associated with its development in a prospective cohort of patients with non-valvular (NV) AF.

The CHADS2 and CHA2DS2-VASc scores for predicting ischemic stroke among East Asian patients with atrial fibrillation: A systemic review and meta-analysis.

Background: Both the CHADS2 and CHA2DS2-VASc scores are well-validated in Western populations for predicting risk of stroke among patients with atrial fibrillation (AF). There is some uncertainty as to which risk score is best to guide optimal anticoagulant therapy among Asian populations with AF.

Methods: A systemic literature search of Cochrane library, Scopus, and PubMed databases was conducted using search terms: atrial fibrillation, CHADS2 and CHA2DS2-VASc.

Relationship between low Ankle-Brachial Index and rapid renal function decline in patients with atrial fibrillation: a prospective multicentre cohort study.

Objective: To investigate the relationship between Ankle-Brachial Index (ABI) and renal function progression in patients with atrial fibrillation (AF).

Design: Observational prospective multicentre cohort study.

Setting: Atherothrombosis Center of I Clinica Medica of 'Sapienza' University of Rome; Department of Medical and Surgical Sciences of University Magna Græcia of Catanzaro; Atrial Fibrillation Registry for Ankle-Brachial Index Prevalence Assessment-Collaborative Italian Study.

Asymptomatic versus symptomatic atrial fibrillation: A systematic review of age/gender differences and cardiovascular outcomes.

Up to 40% of atrial fibrillation (AF) patients are asymptomatic. Despite this, scarce data are available about asymptomatic AF, with regard to its clinical profile and relationship to cerebrovascular and cardiovascular risks. Our objective was to conduct a systematic review and meta-analysis was to study the relationship between age and gender with asymptomatic AF and to establish whether patients with asymptomatic AF have a higher risk of death (all-cause and cardiovascular) and stroke/systemic thromboembolism, when compared to symptomatic AF patients.

Does Mediterranean Diet Reduce Cardiovascular Events and Oxidative Stress in Atrial Fibrillation?

Atrial fibrillation (AF) is characterized by enhanced oxidative stress and is complicated by cardiovascular events (CVEs), which are only partially prevented by anticoagulant treatment. The Mediterranean diet (Med-Diet) has a positive effect on atherosclerotic progression. In a prospective cohort of 709 anticoagulated AF patients, adherence to Med-Diet was assessed to investigate whether Med-Diet may reduce CVEs by lowering oxidative stress.
