Effect of Icosapent-ethyl Ester (IPE) to Reduce the Residual Risk Cardiovascular Disease.

Summary

Cardiovascular diseases (CVDs) are the leading cause of global mortality, despite significant advances in prevention and treatment. Atherosclerosis, a chronic inflammatory condition, underlies ischemic events such as infarction and stroke, triggered by the instability and rupture of plaques. Current guidelines recommend drugs primarily aimed at reducing Low-Density-Lipoprotein cholesterol (LDL-C), arterial pressure, and glucose levels for atherosclerosis patients. However, there is little option of approved medications specifically targeting inflammation within the arterial plaques. Consequently, a significant proportion of patients face residual risks. On the contrary, numerous studies have highlighted the anti-inflammatory effects provided by omega-3 fatty acids (n-3 FA), specially the eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), and their derived oxylipins. These molecules exhibit the ability to enhance the phenotype of macrophages, increasing their capacity for efferocytosis, thereby improving plaque stability. Icosapent ethyl (IPE) is an esterifed version of eicosapentaenoic acid (EPA) and acts as a prodrug in the body to exert its effects. Icosapent ethyl (IPE) was the first fish oil product approved by the US Food and Drug Administration (FDA) to reduce the risk of atherosclerotic cardiovascular disease (ASCVD) in adults. Hence, the hypothesis of this study is that supplementing patients with IPE, in addition to their standard clinical treatment, will enhance macrophage functionality, thereby reducing inflammatory and oxidative stress biomarkers in comparison to a placebo. To test this hypothesis,a Randomized, Double-blind, Placebo-controlled Clinical trial will be performed, in which 294 patients under secondary prevention for CVDs will receive a 6-month supplementation of purified eicosapentaenoic acid-icosapent ethyl (4.0 g) daily or a Placebo (corn oil). Blood samples and anthropometric measurements will be taken at the beginning and end of the period. Basic clinical markers will be assessed, and monocytes will be collected and characterized. Fatty acid profiles and oxylipins will be determined through chromatography coupled with mass spectrometry. Finally, changes in biomarkers for both groups will undergo multivariate analysis to identify characteristics associated with the response to supplementation. Data from this study aims to provide support for physicians considering the prescription of bioactive compounds as a complementary therapy for atherosclerosis, with the goal of reducing residual risks and subsequently decreasing mortality resulting from cardiovascular events.
