Understanding Your Cholesterol Numbers (post 2 of 3)
By Robert Pilchik, MD, Chief of Cardiology at Northern Westchester Hospital
First, a short review of cholesterol basics: The two types of cholesterol in your body – low-density lipoprotein (LDL) and high-density lipoprotein (HDL) – behave totally differently. Over time, excess LDL in your body, largely from fatty foods you eat, builds up in your artery walls as hard plaque, narrowing these vessels and restricting blood flow to your heart and brain. This condition, atherosclerosis, is THE leading cause of heart attack and stroke. By contrast, HDL acts as a vacuum, ridding the arterial walls of cholesterol and flushing it from the body.
