What if we told you that what you think you know about HDL “good” cholesterol is wrong? A new study from researchers at the Cleveland Clinic has some shocking findings about cholesterol. HDL is known for preventing plaque buildup in arteries, but researchers are realizing that it can also turn and contribute to heart disease.
In its good form, HDL is meant to take molecules of cholesterol away from vessel walls and parts of the body to the liver to be removed. However, in the newly discovered dysfunctional or “bad” form of HDL, these molecules that are meant to be removed never make it to the liver. Due to this, it causes inflammation in vessel walls, and people who have a high level of the dysfunctional version are now at a higher risk for developing heart disease.
So, how are doctors able to differentiate between the two different forms of HDL? Researchers developed their own blood test through the Cleveland HeartLab, but may release it as soon as the end of this year. The blood test specifically tests for a protein found in HDL that when it is oxidized starts to cause problems for the heart and artery walls.
Connection Between Cholesterol and Heart Disease
Cholesterol has long been linked to heart disease, and LDL is the “bad” cholesterol which carries 65% of cholesterol in the blood stream. LDL can help form plaque that builds up along artery walls that feed the heart and brain. When HDL works as it should, the “good” cholesterol carries LDL away to the liver and a high level helps to prevent heart disease.
High levels of LDL contribute to a condition called atherosclerosis, a hardening of the arteries, which raises risk for heart attack and stroke.
More than 60% of adults in the U.S. don’t know their cholesterol levels. Knowing these simple facts is an important step towards a healthy future, and at Life Line Screening we offer high cholesterol screenings with a lipid panel test. Learn more about our cholesterol screenings now.
