New Cholesterol Guidelines: Why You Need to Lower Your LDL Levels Sooner

Your chances of developing heart disease are affected by a wide range of risk factors – some you can’t control and others that you can. Among the most glaring of the modifiable factors are your cholesterol levels.

Controlling cholesterol – through diet, lifestyle and medications – has long been seen as one of the most effective ways to lower your risk of cardiovascular disease. And now, the American Heart Association (along with nearly a dozen other medical organizations) is urging a more aggressive approach.

Before we look at some of the highlights of the new guidelines, let’s explore why cholesterol is so dangerous for your body. This waxy substance is transported in your body through the blood stream packaged inside lipoproteins including low-density lipoproteins (LDL) and high-density lipoproteins (HDL).

HDL cholesterol is often referred to as “good,” with modestly higher levels offering protection for your heart. LDL cholesterol is known as “bad” because of its role in allowing fatty accumulation on the walls of your arteries. This buildup narrows your arteries, progressively obstructing blood flow and increasing your risk for heart attack, stroke and peripheral artery disease.

The new guidelines urge a more aggressive approach toward managing cholesterol, with changes that will help detect unhealthy levels sooner and push those levels lower than previously recommended. Among the key takeaways:

New Guidelines: Detecting Heart Disease Risk Earlier

Every year that your body deals with high levels of LDL cholesterol, it quietly builds plaque in the arteries and raises the risk to your arteries and heart. As with many things related to health, younger adults don’t often spend much time thinking about their heart disease risk.

The new guidelines suggest an initial screening of children between the ages of 9 and 11 to look for signs of inherited conditions that could increase risk. Follow-up screenings for everyone around the age of 19 (with repeat screenings at five-year intervals) will more quickly identify patients with unhealthy cholesterol levels.

Men 40 and older and women 45 and older may consider a coronary artery calcium scan. The test looks for early signs of plaque buildup in artery walls. The test can help your doctor decide if, or when, cholesterol-lowering medications should be started.

Also recommended are tests for two proteins. The first is a one-time test for every adult for  lipoprotein(a), which can increase your risk for heart disease.  Levels are mostly determined by genetics, vary by ancestry and do not respond to traditional diet or lifestyle changes. The second tests for apolipoprotein B in patients with high triglycerides, metabolic syndrome or type 2 diabetes. The presence of either protein could suggest the need for robust cholesterol treatment.

New Way To Evaluate Risk

There’s also a new risk calculator, PREVENT, to help doctors estimate the risk of developing cardiovascular disease for patients from age 30 to 79. The calculator considers various factors, including cholesterol levels, body mass index and tobacco use to develop a 10-year risk score.

The risk categories:

• Low: less than 3 percent
• Borderline: 3 percent to 5 percent
• Intermediate: 5 percent to 10 percent
• High: 10 percent or higher

Medications may be recommended for anyone whose risk is considered borderline or higher. The calculator can also offer a 30-year risk assessment for some adults.

Aggressive Treatment Goals for LDL Levels

Finding cholesterol issues earlier will provide a head-start on preventive measures. The new guidelines call for earlier and more aggressive efforts to keep LDL levels low. The average LDL level in the U.S. is 110, though one in four people have a score of at least 130. Severe lipid abnormalities with LDL levels greater than 190mg/dL are 1 in 250 to 300 individuals and associated with up to a fourfold higher risk of heart attack or stroke. If the decision is made to initiate therapy, the new goals target:

• LDL levels below 100 for everyone.
• LDL levels below 70 for anyone with an estimated 10 percent risk of heart attack or stroke in the next 10 years.
• LDL levels below 55 for anyone who has already had a heart attack or stroke.

When exercise and diet are not enough, earlier use of cholesterol-lowering medication is recommended.

Cardiovascular disease is the leading cause of death in the U.S., accounting for one in three deaths. The earlier we can identify and adjust key risk factors – including cholesterol levels – the better chance we have at reducing these preventable deaths. If you haven’t had a conversation with your primary care doctor about your cholesterol, it’s never too early.
