The latest thinking on inherited high cholesterol
About 5% of Americans have low-density lipoprotein (LDL) values of 190 mg/dL or higher. Their risk of heart disease is five times higher than people with near-optimal values (less than 130 mg/dL). Some have familial hypercholesterolemia, a genetic condition that can lead to LDL values up to 350 mg/dL (or even higher in some cases). Known as FH, it's a common cause of early heart attacks.
Why choose bypass surgery over stents?
People who have stable angina despite taking medications can be treated with stents or bypass surgery. The best choice depends on the location and complexity of the artery blockages and other health conditions.
High lipoprotein(a) raises heart attack risk even in healthy people
High levels of lipoprotein(a), or Lp(a)—a variant of LDL (bad) cholesterol— may triple the risk of a heart attack, even among healthy people with no other known risks for heart disease.
Rethinking HDL cholesterol
The scientific understanding of HDL cholesterol has evolved in recent years, and many cardiologists now believe that HDL may be more of a bystander rather than a "good guy" that helps lower heart disease risk. While some types of HDL are great at plucking excess cholesterol from LDL and artery walls (a process referred to as reverse cholesterol transport) other types of HDL don't do this. In clinical trials, medications to raise HDL levels—including a drug specifically designed to improve reverse cholesterol transport—have not succeeded in lowering heart attacks and strokes.
Can you reduce your cholesterol without taking a drug?
People can reduce their LDL cholesterol in three ways. One strategy involves dietary changes, such as eating more fiber-rich foods and swapping saturated fats for unsaturated fat. Another is to take one of several dietary supplements, including psyllium, plant sterols, or red yeast rice. The third entails taking a prescription medication, such as a statin. Many factors can affect whether these different strategies are advisable or useful, including a person's age and other risk factors for heart disease, their current dietary habits, and the quality of the supplements they take.
Is extra-virgin olive oil extra healthy?
Studies have shown a link between lower risks of cardiovascular disease, some cancers, and even dementia in people who consume higher amounts of olive oil. However, no definitive studies show extra-virgin olive oil has greater benefits than regular olive oil.
Web-based app helps people accurately assess need for statin
Using a Web-based app, most people can correctly assess their need for a cholesterol-lowering statin and take the drug appropriately with good results, according to a 2024 study. If approved, the app could facilitate statin use without a doctor's prescription.
Can your blood tests predict your future risk of stress, anxiety, or depression?
A 2024 study found that people with high blood sugar and high triglycerides are more likely to develop chronic stress, anxiety, or depression later in life, compared with people who have low or normal blood sugar levels.
How low should LDL cholesterol go?
People who are at high risk for cardiovascular disease can benefit from driving down "bad" low-density lipoprotein (LDL) cholesterol levels as low as possible to help reduce their risk for heart attacks and strokes. Guidelines recommend that people at high risk aim for LDL levels below 70 milligrams per deciliter (mg/dL). The general population should strive for levels below 100 mg/dL. Taking statins and adopting healthier lifestyle habits like following a plant-based diet and increasing exercise can help manage LDL levels.
