Elevated whole blood viscosity is associated with an impaired insulin-stimulated myocardial glucose metabolism.

Background: Increased whole blood viscosity (WBV) was associated with impaired peripheral glucose metabolism, type 2 diabetes, and cardiovascular disease (CVD). Impaired myocardial glucose metabolism is a risk factor for CVD. Whether an increased WBV is associated with impaired myocardial glucose metabolism is still undefined.

Differences in target organ damage in individuals with intermediate hyperglycemia and type 2 diabetes identified by 1-hour plasma glucose during an oral glucose tolerance test.

Aims: The International Diabetes Federation (IDF) has recently recommended determination of 1-hour glucose during an oral glucose tolerance test (OGTT) to diagnose intermediate hyperglycemia (IH) and type 2 diabetes (T2D). Herein, we investigated the implications of IDF recommendation for characterizing the risk of cardiovascular target organ damage including left ventricular mass normalized by body surface area (LVM index [LVMI]), and myocardial mechano-energetic efficiency normalized by LVM (MEEi) in individuals with IH and T2D.

Methods: LVMI, and MEEi were assessed in 1847 adults classified on the basis of fasting, 1-hour and 2- hour glucose during an OGTT according to the IDF recommendation as having normal glucose tolerance (NGT, n = 736), isolated impaired fasting glucose (iIFG, n = 105), IH (n = 676), and newly diagnosed T2D (n = 330).

Effects of Continuous Positive Airway Pressure Treatment on Vascular Function in a Real-Life Cohort of Elderly Patients with Obstructive Sleep Apnoea Syndrome.

Background: Obstructive sleep apnoea syndrome (OSAS) is an independent risk factor for cardiovascular morbidity and mortality and has a detrimental effect on vascular function, in particular on arterial stiffness and endothelial function. Continuous positive airway pressure (CPAP) is the gold-standard therapy for OSAS and its effects on arterial stiffness and endothelial function have been demonstrated in non-elderly patients.

Objectives: The objective of this study was to evaluate the effect of one year of CPAP treatment on arterial stiffness, through assessment of carotid-femoral pulse wave velocity (cf-PWV), and on endothelial function, through the reactive hyperaemia index (RHi), in a real-life cohort of elderly patients with moderate-to-severe OSAS and several comorbidities.

Individuation of a cut-off value of triglyceride-glucose index for incident diabetes mellitus in patients with essential hypertension.

The prevalence of obesity and diabetes, risk factors for atherosclerotic vascular diseases, is increasing worldwide; therefore, it is desirable to early identify them to reduce cardiovascular events. Thus, we investigated whether the triglyceride-glucose index (TyG index), a new marker of insulin resistance, is associated with incident diabetes in patients with newly diagnosed arterial hypertension. We selected 585 patients with newly diagnosed arterial hypertension referred to our tertiary Clinic of Catanzaro University Hospital for the evaluation of their cardiometabolic risk profile.
