High-density lipoprotein (HDL) is a set of particles with heterogeneous structures that have different functions due to various compounds including surface charge, size, lipid, and protein compounds. Several prospective epidemiological studies have demonstrated that there is a clear inverse relationship between serum HDL concentration and risk of coronary heart disease, despite this relationship, clinical evidence has only challenged the usefulness of higher levels of HDL-C in predicting the risk of cardiovascular diseases (CVD) and have proven that the structure of HDL is altered and loosed function. Therefore, extensive research is needed to identify new agents and biomarkers to improve HDL function and reduce the risk of cardiovascular disease. Given that the most important function of HDL is to transfer excess cholesterol from peripheral tissues and macrophage cells through a receptor called ABCA1 and direct it to the liver, plays an important role in protecting the formation of atherosclerotic plaque. This molecule can provide a strong protective effect against oxidative damage caused by free radicals with intermittent inhibition of the production of pro-inflammatory oxidized lipids in the intima layer of arteries. There is an inverse relationship between the ability to efflux cholesterol and the prevalence of CVD. The ability to remove cholesterol from macrophages by HDL, it is a crucial criterion for determining HDL performance, and it has a strong inverse relationship with carotid intima-media thickness and coronary artery stenosis in angiography independent of HDL level.

In vitro studies have demonstrated that high density lipoprotein particles (HDL-P) antagonize inflammatory processes. We studied the predictive value of HDL-P and inflammatory markers for incident cardiovascular disease (CVD) and non-CVD, non-cancer, chronic inflammatory-related events. Methods: In the Multi-Ethnic Study of Atherosclerosis, we studied 6475 men and women free of overt CVD, baseline age 45-84 years, who had fasting venous samples for lipid profile, lipoprotein particles, and inflammatory markers Interleukin-6 (IL-6), hs-CRP and D-dimer at baseline. Median follow-up was 10.1 years. Poisson regression models predicted non-CVD, non-cancer, chronic inflammatory-related events (death and hospitalization), based on diagnostic codes, n=1054) and CVD events due to coronary heart disease, myocardial infarction, coronary artery disease requiring revascularization, stroke, peripheral arterial disease, congestive heart failure and CVD or unwitnessed death (adjudicated, n=756). Adjustment was for age, race, gender, clinic, heart rate, smoking, body mass index, blood pressure, blood pressure and lipid lowering medication, diabetes mellitus, plus all lipid, lipoprotein particle and inflammatory variables. Results: Non-CVD, non-cancer, chronic inflammatory-related events were inversely associated with the sum of small+medium HDL-P independent of covariates (relative risk (RR) per standard deviation (95% confidence limits), RR: 0.85 (0.79-0.91, P < 0.0001). Non-CVD, non-cancer, chronic inflammatory-related events were positively associated with IL-6, RR:1.19 (1.11-1.27, P < 0.0001) and D-dimer, RR: 1.10 (1.05-1.16, P < 0.0001). CVD was associated with small+medium HDL-P, RR: 0.90 (0.82-0.99, P < 0.03) and IL-6, RR:1.15 (1.06-1.25 P < 0.0001). hsCRP was unrelated to either outcome after adjustment for other inflammatory markers. Conclusion: The long-term inverse association of small+medium HDL-P with non-CVD, non-cancer, chronic inflammatory-related death and hospitalization was stronger than with fatal and non-fatal CVD in subjects initially free of overt CVD. These findings provide clinical evidence that small+medium HDL-P have anti-inflammatory properties and may rethink the importance of HDL-P beyond CVD.
