The American College of Cardiology and the American Heart Association released updated clinical guidance on March 28 regarding blood cholesterol screening and management.
Key Updates in Cholesterol Management
The recommendations mark the first revision since 2018 and appear in the Journal of the American College of Cardiology alongside a presentation in New Orleans.
Focus centers on lowering low-density lipoprotein cholesterol alongside other blood fats such as lipoprotein(a). Experts aim to support more informed, shared decisions between patients and clinicians through these steps.
According to Roger S. Blumenthal, chair of the guideline writing committee, lower LDL cholesterol levels reduce the risk of heart attacks and strokes.
Earlier Screening and Genetic Factors
A key shift involves pushing for screening at younger ages and considering personal risk factors like family history.
Doctors are encouraged to evaluate conditions such as rheumatoid arthritis or life events like early menopause when planning treatment.
Individuals with familial hypercholesterolemia should now begin screening earlier in life, starting around age nine.
The guidance also recommends a one-time test for Lp(a), which can raise heart disease risk by about 40% at specific levels.
Implications for Long-Term Health
A new tool for estimating 10- and 30-year risk of heart attack and stroke replaces the previous model.
The PREVENT calculator includes additional measures such as blood sugar and kidney function for use starting at age 30.
Data from 6.6 million people supports this new model compared to just 26,000 in the earlier version.
Experts suggest shifting toward proactive prevention strategies can change the trajectory of cardiovascular disease for decades.
