Answer
Coronary Heart Disease is linked with the absence of sufficient LDL receptors. LDL receptors are proteins that bind to LDL particles and transport them into the liver for degradation. When LDL receptors are absent or defective, LDL levels can increase and lead to atherosclerosis, which is the buildup of plaque in the arteries. This plaque can block blood flow to the heart, leading to heart attacks and strokes.
