The mitochondrial dysfunction, alongside the modifiable burden of traditional risk factors, drives the development of early-onset coronary artery disease.

Objective: Mitochondrial dysfunction is associated with increased risk of atherosclerosis by disrupting key cellular processes that contribute to premature vascular ageing. However, the specific role of mitochondrial dysfunction in early-onset coronary artery disease (EOCAD), which is increasing at a particularly alarming rate, remains largely unexplored. This study investigated the association of leukocyte mtDNA-CN and mtDNA deletion with the risk of EOCAD.

The burden of radiation exposure in congenital heart disease: the Italian cohort profile and bioresource collection in HARMONIC project.

Background: The European-funded Health Effects of Cardiac Fluoroscopy and Modern Radiotherapy in Pediatrics (HARMONIC) project aims to improve knowledge on the effects of medical exposure to ionizing radiation (IR) received during childhood. One of its objectives is to build a consolidated European cohort of pediatric patients who have undergone cardiac catheterization (Cath) procedures, with the goal of enhancing the assessment of long-term radiation-associated cancer risk. The purpose of our study is to provide a detailed description of the Italian cohort contributing to the HARMONIC project, including an analysis of cumulative IR exposure, reduction trend over the years and an overview of the prospective collection of biological samples for research in this vulnerable population.

Influence of Chromosome 9p21.3 rs1333049 Variant on Telomere Length and Their Interactive Impact on the Prognosis of Coronary Artery Disease.

Background: Both telomere shortening and the chromosome 9p21.3 (Chr9p21) rs1333049 (G/C) variant are involved in coronary artery disease (CAD) risk, likely affecting mechanisms related to cell cycle arrest and vascular senescence. The aim of the study was to examine the link between Chr9p21 rs1333049 variant and leucocyte telomere length (LTL), as well as their interactive effect on the risk of major adverse cardiovascular events (MACEs).

Clinical and Biological Predictors of Cancer Incidence and Mortality in Patients with Stable Coronary Artery Disease.

Clinical and epidemiological evidence has recently revealed a link between coronary artery disease (CAD) and cancer. Shared risk factors and common biological pathways are probably involved in both pathological conditions. The aim of this paper was to evaluate whether and which conventional risk factors and novel circulating biomarkers could predict cancer incidence and death in patients with CAD.

Biochemical but not imaging parameters are predictive of outcome in septic shock: a pilot study.

Background: Septic shock is a severe form of sepsis marked by hypotension with an ominous outcome despite the introduction of modern intensive care. The aim of the present study is to obtain a panel with biomarkers, echocardiographic and vascular parameters to better risk stratify patients and identify those at higher risk of ominous outcome.

Methods: Between May 2013 and April 2016, 35 consecutive patients admitted at the Intensive Care Unit (ICU) of ASST Great Metropolitan Hospital Niguarda with the diagnosis of severe sepsis or septic shock were enrolled.

Gender-Specific Behaviour in Obesity Stages I-II: Imbalance of Aminothiol Status and Adipomyokine Profile in Subjects with Different Insulin Resistance Severity.

The hyperproduction of oxidative stress and inflammatory biomarkers, which is paralleled by decreased levels of antioxidant and anti-inflammatory mediators, is part of cellular mechanisms that contribute to the disruption of metabolic homeostasis in obesity. Whether gender-specific alterations and gender-restricted associations in these biomarkers underlie the increased cardiometabolic risk in men compared to women is unclear. We enrolled 31 women and 29 men, aged ≥50 and ≤70 years and with body mass index ≥ 30 and <40 kg/m.

Correlates of olfactory impairment in middle-aged non-diabetic Caucasian subjects with stage I-II obesity.

Purpose: This study evaluates among middle-aged subjects with obesity the prevalence of olfactory impairment (OI) with respect to normative values and its correlation with body composition, cognition, sleep quality, and inflammation.

Methods: In 60 (31 women, 29 men) volunteers with a body mass index ≥ 30 to ≤ 40 kg/m, aged ≥ 50 to ≤ 70 years, we assessed olfaction by the Sniffin' Stick test. We measured anthropometrics, body composition and metabolic profiles and evaluated cognition by the MiniMental State Examination (MMSE) and sleep disturbances by the Insomnia Severity Index (ISI).

Irisin and markers of metabolic derangement in non-diabetic Caucasian subjects with stage I-II obesity during early aging.

Irisin concentrations are decreased in subjects with overt diabetes and upregulated in those with obesity or impaired fasting glucose. However, gender-balanced data in older populations, in whom risk factors commonly culminate in overt cardiovascular disease, are scarce. We assessed in non-diabetic Caucasian subjects with stage I-II obesity in the early aging range (50 to 70 years), the relationship between irisin, body composition and markers of metabolic derangement by gender.

Systematic Lab Knowledge Integration for Management of Lipid Excess in High-Risk Patients: Rationale and Design of the SKIM LEAN Project.

SKIM LEAN aims at exploiting Electronic Health Records (EHRs) to integrate knowledge derived from routine laboratory tests with background analysis of clinical databases, for the identification and early referral to specialist care, where appropriate, of patients with hypercholesterolemia, who may be inadequately controlled according to their cardiovascular (CV) risk level. SKIM LEAN addresses gaps in care that may occur through the lack of coordination between primary and specialist care, incomplete adherence to clinical guidelines, or poor patient's compliance to the physician's prescriptions because of comorbidities or drug side effects. Key project objectives include: (1) improved health professionals' competence and patient empowerment through a two-tiered educational website for general practitioners (GPs) and patients, and (2) implementation of a hospital-community shared care pathway to increase the proportion of patients at high/very-high CV risk (Familial Hypercholesterolemia, previous CV events) who achieve target LDL cholesterol (LDL-C) levels.

Galectin-3 and outcomes after anterior-wall myocardial infarction treated by primary percutaneous coronary intervention.

Aim: Galectin-3 (Gal-3), a biomarker of inflammation, tissue repair and fibrogenesis, is associated to left ventricular remodeling after ST-elevated myocardial infarction (STEMI), but its relation with long-term outcomes is unclear.

Methods: In 103 consecutive patients with a first anterior STEMI treated by primary angioplasty, we assayed Gal-3 and NT-proBNP.

Results: Age was 65 (56-76) years, 28% were women.

A serving of blueberry (V. corymbosum) acutely improves peripheral arterial dysfunction in young smokers and non-smokers: two randomized, controlled, crossover pilot studies.

Several studies have documented the important role of polyphenol-rich foods in the modulation of vascular remodelling and function. This study aimed to evaluate the capacity of a single portion of blueberry (V. corymbosum) to acutely improve peripheral arterial dysfunction in a group of young volunteers.

Medium-term effect of sublingual l-glutathione supplementation on flow-mediated dilation in subjects with cardiovascular risk factors.

Objective: Supplementation of glutathione (GSH) may be a positive strategy to improve the endogenous antioxidant defense required to counteract many acute and chronic diseases. However, the efficacy of GSH treatment seems to be closely related to type of administration, degree of absorption, and increase of its concentrations. The aim of this study was to test a new sublingual formulation of L-GSH, which enters directly the systemic circulation, to assess its efficacy on circulating biochemical markers of hepatic metabolism, lipid profile, and oxidative stress and on peripheral vascular function compared with placebo in patients with cardiovascular risk factors (CVRF).

Intra- and interday repeatability of peripheral arterial function: suitability and potential limitations.

Objective: This study aimed to investigate the inter-and intraday repeatability of RHI measured by Endo-PAT in healthy volunteers.

Methods: Interday RHI repeatability was tested in two consecutive days in a group of 31 male subjects. Intraday repeatability was investigated at baseline and after 2 and 4 hour in a group of 16 volunteers.

Antioxidant and inflammatory biomarkers for the identification of prodromal Parkinson's disease.

Objectives: We explored the role of oxidative stress and inflammatory molecules as potential Parkinson (PD) biomarkers and correlated biological with non-motor abnormalities (olfactory impairment and dysautonomia), in patients with idiopathic REM behavior disorder (iRBD) (prodromal PD) and established PD.

Methods: We recruited 11 iRBD and 15 patients with idiopathic PD (Hohen&Yahr 1-3, on L-DOPA and dopamine agonists combination therapy) and 12 age- and sex-matched controls (CTRL). We measured total olfactory score (TOS), autonomic function [deep breathing (DB), lying to standing (LS) and Valsalva manoeuvre (VM) ratios], blood reduced glutathione (Br-GSH), oxidative stress and inflammatory markers (neopterin).

Galectin-3 predicts left ventricular remodelling after anterior-wall myocardial infarction treated by primary percutaneous coronary intervention.

Objectives: Despite modern reperfusion therapies, left ventricular remodelling (LVR) occurs frequently after an ST-elevated myocardial infarction (STEMI) and represents a strong predictor of mortality and heart failure. Galectin-3 (Gal-3), a novel biomarker involved in inflammation, tissue repair and fibrogenesis, might be a valuable predictor of LVR.

Methods: We enrolled consecutively admitted patients with a first anterior STEMI and left anterior descending artery occlusion treated by primary percutaneous coronary intervention (pPCI).

Inflammatory and antioxidant pattern unbalance in "clopidogrel-resistant" patients during acute coronary syndrome.

Background: In acute coronary syndrome (ACS), inflammation and redox response are associated with increased residual platelet reactivity (RPR) on clopidogrel therapy. We investigated whether clopidogrel interaction affects platelet function and modulates factors related to inflammation and oxidation in ACS patients differently responding to clopidogrel.

Material And Methods: Platelet aggregation was measured in 29 ACS patients on dual (aspirin/clopidogrel) antiplatelet therapy.

Myocardial interleukin-6 in the setting of left ventricular mechanical assistance: relation with outcome and C-reactive protein.

Background: In left ventricular assist device (LVAD) recipients, plasma levels of interleukin (IL)-6 are associated with Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) profiles, reflecting post-operative risk. However, it is not clear how the cardiac level of IL-6, detectable on the tissue samples at the time of implantation, can contribute to predict the post-operative outcome.

Methods: In 40 LVAD recipients, blood and myocardial samples from LV-apex were collected at the time of implantation to assess plasma and cardiac IL-6 levels.

Identification of genetic markers for treatment success in heart failure patients: insight from cardiac resynchronization therapy.

Background: Cardiac resynchronization therapy (CRT) can improve ventricular size, shape, and mass and reduce mitral regurgitation by reverse remodeling of the failing ventricle. About 30% of patients do not respond to this therapy for unknown reasons. In this study, we aimed at the identification and classification of CRT responder by the use of genetic variants and clinical parameters.

Effects of sapropterin on endothelium-dependent vasodilation in patients with CADASIL: a randomized controlled trial.

Background And Purpose: Cerebral autosomal-dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), a rare autosomal dominant disorder caused by NOTCH3 mutations, is characterized by vascular smooth muscle and endothelial cells abnormalities, altered vasoreactivity, and recurrent lacunar infarcts. Vasomotor function may represent a key factor for disease progression. Tetrahydrobiopterin, essential cofactor for nitric oxide synthesis in endothelial cells, ameliorates endothelial function.

Relationship between early inflammatory response and clinical evolution of the severe multiorgan failure in mechanical circulatory support-treated patients.

Background: The mechanical circulatory support (MCS) is an effective treatment in critically ill patients with end-stage heart failure (ESHF) that, however, may cause a severe multiorgan failure syndrome (MOFS) in these subjects. The impact of altered inflammatory response, associated to MOFS, on clinical evolution of MCS postimplantation patients has not been yet clarified.

Methods: Circulating cytokines, adhesion molecules, and a marker of monocyte activation (neopterin) were determined in 53 MCS-treated patients, at preimplant and until 2 weeks.

[Screening of asymptomatic left ventricular systolic dysfunction in a population sample at high cardiovascular risk in Lombardy (Italy): the DAVID-Berg study].

Background: Prevalence of asymptomatic left ventricular systolic dysfunction (ALVSD) increases with age and cardiovascular (CV) risk exposure. Early diagnosis and treatment allow reducing heart failure and fatal and non-fatal event rates. Data on ALVSD prevalence in Italy are still scarce and ALVSD remains commonly under-diagnosed in primary care, where diagnostic facilities are limited.
