HDL-Cholesterin

High-Density Lipoprotein Cholesterol (HDL-C) is a key component of the lipid profile, often referred to as 'good' cholesterol. It is a complex of lipids and proteins that transports cholesterol from the arteries to the liver for excretion or re-utilization. Clinically, HDL-C is significant as it is inversely related to the risk of atherosclerotic cardiovascular disease (ASCVD), which includes coronary artery disease, peripheral vascular disease, and cerebrovascular disease. Low levels of HDL-C are associated with increased risk of these conditions, while high levels are generally protective. In the context of athletic performance and biohacking, maintaining optimal HDL-C levels is considered beneficial for cardiovascular health and longevity. However, very high levels may also pose risks, particularly in the presence of genetic factors. Caveats in measuring HDL-C include potential confounders such as acute illness, medications, and genetic disorders. Fasting is typically required for accurate measurement, and levels can vary based on time of day and other physiological factors.
