Hyperlipidemia is associated with a higher rate of cardiovascular, cerebrovascular, and peripheral vascular disease. Conventional drugs such as statins are effective in controlling hyperlipidemia; however, they are associated with various side effects, especially myalgia. Nutraceutical lipid-lowering interventions are becoming increasingly popular, particularly among patients who are intolerant or refractory to statins.

Background: Carbohydrate Antigen 125 (CA125) is the most widely used biomarker in ovarian cancer screening. In patients with heart failure (HF), increased levels of CA125 have been observed and related to disease severity. Our objective was to determine the association of CA125 levels with two biomarkers of adverse remodeling in HF patients with reduced ejection fraction (HFrEF).

Background And Aims: Non-alcoholic fatty liver (FL) is comorbid with obesity, metabolic syndrome and type 2 diabetes. Atherogenic dyslipidaemia (AD), frequent in FL, is associated with risk of micro- and macrovascular complications. Given the paradoxical ocular protection of FL in T2DM, we studied how FL modulates micro- and macrovascular complications as a function of AD.

Inhibitors of sodium-glucose cotransporter 2 (SGLT2) inhibitors have shown effective glucose-lowering effects associated with improved clinical outcomes in diabetic patients and heart failure patients. As SGLT2 inhibitors can increase phosphate levels, they can also modulate FGF-23 production, a hormone directly involved in regulation of bone and mineral metabolism, but also a strong predictor of adverse cardiovascular events. We therefore discuss the relevance of FGF-23 as a companion testing of SGLT2 treatment, in addition to standard clinical biology tests.

Background: Pulmonary transit time (PTT) from first-pass perfusion imaging is a novel parameter to evaluate hemodynamic congestion by cardiac magnetic resonance (cMR). We sought to evaluate the additional prognostic value of PTT in heart failure with reduced ejection fraction over other well-validated predictors of risk including the Meta-Analysis Global Group in Chronic Heart Failure risk score and ischemic cause.

Methods: We prospectively followed 410 patients with chronic heart failure with reduced ejection fraction (61±13 years, left ventricular (LV) ejection fraction 24±7%) who underwent a clinical cMR to assess the prognostic value of PTT for a primary endpoint of overall mortality and secondary composite endpoint of cardiovascular death and heart failure hospitalization.

Aims: Besides regulating calcium-phosphate metabolism, fibroblast growth factor 23 (FGF-23) has been associated with incident heart failure (HF) and left ventricular hypertrophy. However, data about FGF-23 in HF and preserved ejection fraction (HFpEF) remain limited. The aim of this study was to assess the association between FGF-23 levels, clinical and imaging characteristics, particularly diffuse myocardial fibrosis, and prognosis in HFpEF patients.

Background: New recommendations call for lowering LDL- < 55 mg/dL and non-HDL- < 85 mg/dL in very-high cardiovascular risk (VH-CVR) patients with type 2 diabetes (T2DM). This study assessed the proportion of VH-CVR diabetics currently meeting these primary and secondary lipid targets, and which therapies/phenotypes predict combined goals achievement.

Methods: We analysed the cardiometabolic phenotype, use of lipid-modulatind drugs (LMD), pre- and post-LMD lipids levels, and CV complications among 1196 T2DM with high ( = 221; 18%) or VH-CVR ( = 975; 82%).

Background: The usefulness of C-reactive protein (CRP) to predict cardiovascular disease (CVD) in type 2 diabetes (T2DM) remains controversial. As many factors linked to obesity can modulate CRP in T2DM, we comprehensively revisited the cardiometabolic phenotype of patients with normal or raised CRP, taking into account the sexual dimorphism of its serum value.

Methods: 1005 T2DM patients (651 males, 354 females; macroangiopathy 38%; coronary artery disease 26%; microangiopathy 47%) were divided depending on whether CRP level was ≤ or >3 mg/L.

Objectives: This study sought to compare the prognostic value of 2-dimensional (2D) right ventricular (RV) speckle tracking (STE) against cardiac magnetic resonance (CMR) RV ejection fraction (EF) and feature tracking (FT) and conventional echocardiographic parameters on overall and cardiovascular (CV) survival in patients with heart failure with reduced EF (HFrEF).

Background: Prior works showed that RV systolic function predicts prognosis in HFrEF. 2D RVSTE had recently been proposed as new echocardiographic method to evaluate RV dysfunction.

Fibroblast growth factor 23 (FGF-23), a key hormone for the regulation of the phosphorus homeostasis, has also several direct effects on cardiac function. In heart failure (HF), the increase of FGF-23 participates to cardiac hypertrophy and remodeling. Measurement of the intact, biologically active hormone is now available.

Background: This study investigated the isolated and crossed effects of familial histories (FH) of early onset coronary heart disease (EOCHD) and type 2 diabetes mellitus (T2DM) on diabetic offspring.

Methods: The cardiometabolic phenotype of 1098 T2DM patients was analyzed according to an FH of T2DM and/or EOCHD, including body composition, fasting insulinemia, insulin sensitivity, β-cell function (BCF), lipids, lipoprotein(a), high-density lipoprotein (HDL) number and functionality, and micro- and macrovascular complications.

Results: Mean age and T2DM duration were 69 and 18 years, respectively; 64% of patients were male, 50% (n = 550) had an FH of T2DM (DM[+]), and 13% (n = 145) had an FH of EOCHD (EOCHD[+]).

Cholesfytol, a lipid-lowering dietary supplement with antioxidant and anti-atherosclerotic properties, combines red yeast rice (RYR) and olive extract (5mg hydroxytyrosol equivalent) and represents an alternative for patients who do not wish or are unable to use chemical statins, including individuals with previous statin-associated muscle symptoms (SAMS). A 2-months observational non-randomized study was performed to evaluate the efficacy, tolerance and safety of Cholesfytol (1 tablet/day) in 642 hypercholesterolemic patients (mean age: 59 yrs; total cholesterol (TC) ≥200; LDL-C ≥140mg/dl). Patients were followed by 126 GPs, and included irrespective of SAMS history and/or diabetes.

Aims: Although women have higher high-density lipoprotein cholesterol (HDL-C) than have men, their HDL particles are also prone to become small, dense, and dysfunctional in case of type 2 diabetes mellitus (T2DM). To assess the vascular risk related to HDLs of different sizes/densities without direct measurement, we adjusted HDL-C to its main apolipoprotein (apoA-I) as [HDL-C/apoA-I]. This ratio estimates HDL sizes and provides indices as to their number, cholesterol load, and density.

Background: Lipoprotein(a) (Lp(a)), a variant low-density lipoprotein (LDL), is a major genetic risk factor for cardiovascular disease. It is unknown whether an inverse relationship exists between Lp(a) and β-cell function (BCF), as for LDL-cholesterol (LDL-C) lowering by statins. We therefore assessedthe cardiometabolic phenotype of 340 men with type 2 diabetes mellitus (T2DM) in relation to Lp(a), focusing on BCF and hyperbolic product [BxS], which adjusts BCF to insulin sensitivity and secretion.

The role of high-density lipoprotein cholesterol (HDL-C) as modifiable risk factor for cardiovascular (CV) disease is increasingly debated, notwithstanding the finding that small-dense and dysfunctional HDL are associated with the metabolic syndrome and T2DM. In order to better clarify the epidemiological risk related to HDL of different size/density, without resorting to direct measures, it would seem appropriate to adjust HDL-C to the level of its main apolipoprotein (apoA-I), thereby providing an [HDL-C/apoA-I] ratio. The latter allows not only to estimate an average size for HDLs, but also to derive indices on particle number, cholesterol load, and density.

Soluble fms-like tyrosine kinase-1 (sFlt-1) is an endogenous inhibitor of endothelial growth factors, such as placental growth factor (PlGF), which modulates cardiovascular (CV) remodeling. We determine sFlt-1 levels in patients with heart failure (HF) and its relationship to adverse cardiovascular (CV) events and biomarkers of cardiovascular risk. Levels of sFlt-1 and PlGF levels were also determined in healthy volunteers and patients with type 2 diabetes mellitus (T2DM).

Background: Type 2 diabetes (T2DM) is associated with obesity, insulin resistance and the metabolic syndrome (MetS). In non-diabetic populations, features of metabolic obesity (MO) are observed in a minority of normal-weight (NW) subjects. The cardiometabolic status of metabolically obese but normal-weight (MONW) individuals has not yet been phenotyped in T2DM.
