High cholesterol is a major cardiovascular risk factor that affects millions worldwide. It can contribute to atherosclerosis, and higher LDL levels increase the likelihood of heart disease and stroke. As you move through this page, you’ll explore who is most affected—such as adults with obesity, diabetes, a family history, or smoking—and the screening, lifestyle, and medication strategies that help lower LDL.
Key Takeaways
- High LDL cholesterol increases heart disease risk by 2-3 times
- High cholesterol causes 4.4 million deaths yearly worldwide
- Atherosclerosis from high cholesterol leads to 17.9 million CVD deaths annually
- Nearly 94 million U.S. adults age 20 or older have borderline high cholesterol
- About 1 in 3 adults in the United States has high cholesterol
- High cholesterol is particularly common among postmenopausal women
- AHA recommends screening every 4-6 years starting age 20
- Limit saturated fats to <6% daily calories
- 150 minutes moderate aerobic exercise weekly
- Obesity is associated with a 2-3 fold increased risk of high cholesterol
- Smoking lowers HDL cholesterol by up to 10%
- Diabetes doubles the risk of high cholesterol complications
- Statins reduce statin users' statin: Statins reduce heart attack risk by 25-35%
- Lifestyle changes lower LDL by 5-10%
- PCSK9 inhibitors reduce LDL by 60%
High LDL cholesterol drives millions of deaths worldwide and raises heart and stroke risk, making regular screening and lifestyle changes vital.
