Dysglycemia as a pre-stage of diabetes mellitus and abdominal obesity are closely interrelated at multiple levels and by a whole array of complex mechanisms, many of which seem to have the potential of causing harm to large blood vessels, in particular to coronary and peripheral vascular segments. Both conditions are associated with elevated circulating concentrations of free fatty acids in conjunction with insulin resistanc Read More

The present paper examines major evidences on the correlation between pre-diabetes, diabetes and cardiovascular risk, especially focusing on early and multifactorial treatment strategies holding the potential to delay the occurrence of micro- and macro-vascular complications causing impaired quality of life and reduced survival.

Diabetic dyslipidemia is due to a multiple array of metabolic abnormalities determining a typical phenotype characterized by increased plasma triglycerides, reduced HDL and a preponderance of small, dense LDL. This dyslipidemia, defined as atherogenic dyslipidemia, is thought to be highly responsible for the increased cardiovascular risk in diabetes mellitus. Several lines of evidence indicate that the increased liver producti Read More

In almost every epidemiological analysis so far performed a strong correlation always emerges between degree of hyperglycemia and risk of both micro- and macrovascular complications. However, whereas lowering plasma glucose levels by intensive treatment has proven to reduce the risk of development of retinopathy, nephropathy and neuropathy, the effect on macrovascular complications has remained quite doubtful. Mult Read More

Patients with diabetes and prediabetes are at high risk for micro- and macrovascular complications. A multifactorial management strategy improves their prognosis considerably. Of concern is that these patients often fall between two specialties: cardiovascular medicine and diabetology. Practice guidelines for this patient category have been issued in collaboration between the European Society of Cardiology Read More

Atherosclerosis is a chronic inflammatory disease that is based on the interaction between inflammatory cell subsets and specific cells in the arterial wall. SIRT1 deacetylates histone and non-histone proteins and has been implicated in protective effects of caloric restriction on lifespan and metabolic pathways in yeast, nematodes, and mice. In the vasculature of rodents, SIRT1 mediates vasodilatation through the release of Read More

The present work is addressing the latest advances made in understanding the molecular mechanisms of vascular aging. Increased production of reactive oxygen species (ROS) is the common denominator of vascular aging, endothelial dysfunction and atherosclerosis. ROS are generated by different intracellular molecular pathways. In view of its role in determining the redox state of the cells and their responses to free radic Read More

Cardiovascular disease is multidimensional and new ideas are needed to develop the conventional risk factor paradigm that has been based on the Framingham Heart Study since more than 30 years. Traditional risk factors such as hypertension, smoking, hyperlipidemia and diabetes can only explain about 50% of the distribution of coronary heart disease whereas the inclusion of new risk markers or protective markers may inc Read More

Arterial aging, characterized by arterial stiffening that is clinically evaluable as aortic pulse wave velocity, is risky for CV events, disability, and loss of cognitive function. Today the only adopted strategy to decrease arterial aging/ arterial stiffness is represented by decreasing BP. Selective antihypertensive drug classes (calcium channel blockers, converting enzyme inhibitors, angiotensin type 1 receptor antagonists) showed Read More

Loss of normal endothelial function and bioactivity of nitric oxide (NO), associated with increased production of reactive oxygen species (ROS), are characteristics of cardiovascular disease states. There is good experimental evidence that these abnormalities are causally related to cardiovascular disease pathogeneses, and are amenable to therapeutic intervention. However, simple attempts to increase NO levels or Read More

Although the impressive progression of modern diagnostic opportunities and therapeutic options, cardiovascular diseases still represent the leading causes of morbidity and mortality, worldwide. Beyond the effective pharmacological treatment of major cardiovascular disease or sequelae, however, cardiovascular diseases developing in adult individuals are largely preventable. The substantial failure to prevent cardiovascul Read More

The need of early, preclinical detection of disease is given by the fact that in 50% of patients dying due to coronary death, mortality is neither heralded by cardiac symptoms nor diagnosis make .The risk during life of suffering of consequences of atherosclerosis can be efficiently assessed through the Framingham risk score (among several other global risk scores). Global risk scores although originally formulated to give a Read More

All coronary patients should be advised and have the opportunity to access a comprehensive cardiovascular prevention and rehabilitation programme, addressing all aspects of lifestyle - smoking cessation, healthy eating and being physically active - together with more effective management of blood pressure, lipids and glucose. To achieve the clinical benefits of a multidisciplinary and multifactorial prevention pr Read More

Low high-density lipoprotein (HDL) cholesterol levels are associated with an increased risk of coronary artery disease and myocardial infarction. Experimental studies have identified several potential anti-atherogenic properties of HDL, including promotion of macrophage cholesterol efflux, endothelial nitric oxide stimulation, anti-inflammatory and anti-thrombotic effects. These observations have lead to the important questi Read More

The plasma levels of high-density lipoprotein (HDL) cholesterol are inversely related to cardiovascular risk. Traditional HDL-raising therapies, like fibrates, PPAR-γ agonists, and nicacin, among others, are associated with undesirable side effects, limited efficacy, or have not yet been shown to improve morbidity and mortality on top of statins in clinical outcome trials. A novel pharmacological target for raising circulating HDL-C l Read More

Among patients with atherothrombosis, including coronary artery disease (CAD), cerebrovascular disease (CVD), and peripheral arterial disease (PAD), patients with PAD generally have the worse prognosis. The Reduction of Atherothrombosis for Continued Health (REACH) Registry characterized the atherothrombotic risk factor profile, and evaluated treatment intensity and cardiovascular events among different ath Read More

Multisite artery or polyvascular disease is common. In the REACH registry, 15.9% of patients with either established atherosclerotic arterial disease or at least 3 risk factors for atherothrombosis had symptomatic polyvascular disease. History of risk factors and known co-morbidities, as well as a thorough physical examination, are mandatory in the initial screening and diagnostic work-up. Various non-invasive imaging techniques ( Read More

Multisite artery disease (MSAD) affects 15% to 30% of patients with clinically manifest atherosclerosis, and has a relevant negative impact on prognosis. However, studies specifically focused on MSAD are very few, and available evidence is scarce. Importantly, patients with MSAD require an integrated management, possibly by a “Vascular Team” composed of the different specialists involved in the treatment of atheroscler Read More
