Postprandial Dyslipidemia clinical trials

Relation Between Postprandial Lipogram and Coronary Artery Disease Severity

Coronary artery disease (CAD) is usually used to refer to the pathological problem affecting the coronary arteries (usually atherosclerosis) that leads to Coronary Heart disease (CHD) which includes the diagnoses of angina pectoris, MI and silent myocardial ischemia. Despite the mortality for this condition has gradually declined over the last decades in western countries, it still causes about one-third of all deaths in people older than 35 years. Dyslipidemia is very important risk factors of atherosclerosis that is one of the causes leading to cardiovascular disease Despite management of dyslipidemia by controling fasting total plasma cholesterol and LDL cholesterol as these are the best biomarkers for prediction of cardiovascular diseases (CVD) risk. LDL elevation is absent in many patients with atherosclerosis and about 1/3 of cardiac events remains to be unpredicted using this method. Even more, in fasting normolipidemic subjects, increased CVD risk is associated with an exaggerated postprandial lipemic response. Postprandial dyslipidemia is defined as a rise in triglyceride-rich lipoproteins (TRLs), including chylomicron remnants (CMRs) and remnant lipoproteins (RLPs), after eating, has drawn an increasing interest recently because of its association with cardiovascular events. Chylomicron remnants (CMRs) have been shown to penetrate the artery wall and to be retained within the intima. Endothelial dysfunction is an initial process of atherogenesis and it contributes to the pathogenesis of CHD. Postprandial hyperlipidemia (postprandial hypertriglyceridemia) is involved in the production of proinflammatory cytokines, recruitment of neutrophils, and generation of oxidative stress, resulting in endothelial dysfunction
