Cholesterol and
Cardiovascular Disease
Cardiovascular disease (CVD) is the leading cause of death globally, representing 32%
of all deaths, more than cancer and chronic lower respiratory disease combined.1-3 Nearly all of
us have either known someone affected by CVD, or been affected by it directly.
A major risk factor for cardiovascular disease is low-density lipoprotein cholesterol (LDL-C). LDL-C is a lipoprotein that, along with its backbone, apolipoprotein B (ApoB), carries most of the cholesterol in the blood.5 When LDL-C levels are high, cholesterol particles can become trapped in artery walls, ultimately leading to a blockage of critical arteries in various organ systems, causing heart attacks and strokes. This process, known as atherosclerosis, is the leading cause of cardiovascular disease.5,6
Many factors can impact a person’s risk of having increased levels of LDL-C, many of which we cannot control:7
- Family history of hypercholesterolemia
- Race/ethnicity
- Increasing age
- Medical conditions (such as chronic kidney disease)
- Certain medications
- Unhealthy lifestyle habits
LDL-C builds up in artery walls.
Deposits can cause vessels to suddenly become blocked—or blood
clots to form—causing a heart attack or stroke.
