What is the link between blood cholesterol and heart disease?
Having high blood cholesterol is one of the main risk factors for heart disease. The higher one’s total cholesterol, the greater the chance of developing heart disease and/or having a heart attack according to the National Heart Lung and Blood Institute (NHLBI). High levels of cholesterol in the blood can lead to unwanted build-up in the artery walls, narrowing blood flow to the heart. This decreased blood flow to the heart causes heart disease, which can lead to heart attack, stroke and even death.
