Diabetes is none of the most common, chronic diseases worldwide and affects nearly 200 million people. It is the fourth or fifth leading cause of death in developed countries, and it is expected that diabetes will reach epidemic proportions, affecting 333 million people globally by 2025.
The metabolic syndrome is a cluster of the most dangerous cardiovascular risk factors and includes diabetes and pre-diabetes in addition to abdominal obesity, low high-density lipoprotein cholesterol, high triglycerides and hypertension. It is estimated that around a quarter of the world's adult population has metabolic syndrome, and are twice as likely to die and three times as likely to have a heart attack or stroke when compared to people without the syndrome. In addition, non-diabetic people with metabolic syndrome have a fivefold greater risk of developing type 2 diabetes. The clustering of cardiovascular risk factors that typifies the metabolic syndrome is now considered the driving force for a cardiovascular disease epidemic.
Metabolic syndrome has been recently defined by a Consensus Conference of the International Diabetes Federation as a cluster of clinical and laboratory signs characterized by the presence of abnormal deposition of fat tissue in the abdomen and visceral districts, and at least two other clinical and laboratory abnormalities, including altered glucose metabolism or type 2 diabetes and decreased levels of high-density lipoprotein cholesterol. One of the underlying pathophysiological mechanisms of metabolic syndrome is insulin resistance, characterized by an increased glucose output from the liver, and reduced glucose uptake in the muscle and adipose tissue cells. Drugs whose mechanism of action consists of increasing insulin sensitivity in the target tissues are able to reduce the clinical manifestations and consequences of metabolic syndrome.
While each individual component of metabolic syndrome confers an increased risk of cardiovascular-related complications or death, this risk is more pronounced when the syndrome itself is present. The more components of metabolic syndrome are evident, the higher is the cardiovascular mortality rate.
