1 :
HDL carries cholesterol from the body tissues to the liver. Lower HDL levels result in more cholesterol in blood leading to increased risk of atheroma formation,and Coronary Heart Disease.
2 :
Coronary Heart Disease is primarily caused by inflammation and infection. HDL is a major carrier of antioxidant enzymes such as paraoxonase, which reduce inflammation. HDL is only weakly related to the total amount of cholesterol in the blood. HDL is one of the proteins that transport cholesterol and cholesterol esters in the blood. Low HDL does not cause heart disease, anymore than high LDL does. However, low HDL can be a marker for chronic inflammatory states that contribute to arterial wall damage
