Brief Summary

Cardiovascular diseases (CVDs) are the leading cause of mortality worldwide, reaching the 31% of deaths in 2012. CVDs represent also the major cause of disability in developed countries and has been estimated that their growing burden could lead to a global increase in loss of disability-adjusted life years (DALY), from a loss of 85 million DALYs of 1990 to a loss of \~ 150 million DALYs in 2020, becoming a major cause of no psychic responsible for lost productivity. Several risk factors contribute to the aetiology and development of CVD. These factors have been traditionally stratified into modifiable risk factors through the lifestyle changes or by taking a pharmacologic treatment (e.g. hypertension, smoking, diabetes mellitus, hypercholesterolemia) and not modifiable risk factors (age, male sex and family history). Essential hypertension is the most common modifiable risk factor in the general population, with a prevalence in Western Countries -including Italy- ranging between about 25-45%. Given the large prevalence of the disease of the general population, hypertension is responsible for the vast majority of CVD in individuals with different CV risk profiles, despite the availability of effective and well tolerated antihypertensive therapies. In this regard, several reports have shown that hypertensive patients often present additional CV and metabolic risk factors, mostly hypercholesterolemia, hypertriglyceridemia, metabolic syndrome and diabetes, which further contribute to increase the individual risk of developing hypertension-related complications, including stroke, end-stage renal disease, congestive heart failure, and CVD death. The concomitant presence of hypertension and dyslipidaemia is also responsible for the objective difficulty in achieving the recommended therapeutic targets for BP and cholesterol levels in a setting of clinical practice. Several pharmacological and non-pharmacological interventions have been proposed for ameliorating the relatively low rates of control of hypertension. Among these, an extensive use of nutrients and food supplements has been shown to provide favourable effects in the management and control of high-normal blood pressure (BP) (or pre-hypertension), that increases the risk of developing hypertension, cardiovascular diseases, and renal failure.
