Heart-healthy diets including phytostanol ester consumption to reduce the risk of atherosclerotic cardiovascular diseases. A clinical review.

The risk of atherosclerotic cardiovascular diseases (ASCVDs) can be reduced by lowering low-density lipoprotein cholesterol (LDL-C) concentrations. Nevertheless, ASCVDs still cause most deaths worldwide. Here, we discuss the prevention of ASCVD and the event risk with a focus on heart-healthy diets, i.e., low intakes of saturated and trans-fatty acids and cholesterol, and high intakes of unsaturated fatty acids, viscous fibre, and dietary phytostanols as fatty acid esters, according to international dyslipidaemia treatment guidelines. Calculations based on both FINRISK and Cholesterol Treatment Trialists' Collaborators regression equations indicate that heart-healthy diets combined with phytostanol ester reduce LDL-C concentrations to such an extent that the 10-year estimated reduction in the incidence of coronary artery disease would be 23%. This information can be used, in particular, to prevent the development of subclinical atherosclerosis in healthy middle-aged populations and the progression of atherosclerosis to ASCVD. The outcome of simple and feasible dietary changes, and, when needed, combined with statins, can be significant: reduced mortality, an increased number of healthy life-years, and reduced healthcare costs.
