Summary

The joint ESC/EAS guidelines for the management of dyslipidaemias recommend, for patients at low/moderate CV risk with raised LDL-C, a set of measures collectively defined as "lifestyle interventions", with use of drugs only if the LDL-C levels cannot be controlled with such lifestyle interventions. "Lifestyle interventions" also includes food supplements. The reason is the following: a simple "dietary advice" has been shown (Cochrane review and meta-analysis, Rees et al, 2013) to achieve a modest reduction of total-C and LDL-C. The review reports: Dietary advice reduced total serum cholesterol by 0.15 mmol/L (95% CI 0.06 to 0.23) and LDL cholesterol by 0.16 mmol/L (95% CI 0.08 to 0.24) after 3 to 24 months." An average reduction of LDL-C by 0.16 mmol/L (6.2 mg/dL) is definitely insufficient to control the level of LDL-C in those subjects. Therefore, those subjects would lose motivation to keep dieting. In this context, use of supplements would significantly amplify the result of diet. A significant proportion of ischemic cardiovascular events are believed to be supported by the coexistence of traditional cardiovascular risk factors such as diabetes, hypertension, dyslipidemia, smoking, and others. The aggregation of these factors is accompanied by a significant increase in the risk of cardiovascular events. Observational studies shown the existence of a relationship between cholesterolemia and coronary heart disease, clearly showing that subjects with even modestly increased total cholesterol values over time develop both fatal and non-fatal vascular events with a higher frequency compared to subjects with similar characteristics, but with lower basal values of cholesterol. Numerous controlled intervention studies, on the other hand, have shown that there is a close correlation between cholesterol reduction and cardiovascular risk; in fact, reductions in the plasma concentration of total and LDL-C, obtained through lifestyle modification or specific drugs, result in reductions in the incidence of major coronary events. The effectiveness of these interventions has been demonstrated both in subjects in primary prevention and in patients in secondary prevention.
