A one-time infusion of a gene-editing therapy called CTX310 may safely lower cholesterol and triglyceride levels, according to a small preliminary trial. The first-in-human study, published in 2025, included 15 people with uncontrolled LDL cholesterol, triglycerides, or both.

For stroke survivors, reaching a very low LDL (bad) cholesterol level may reduce their risk of future strokes and other cardiovascular problems, according to a 2025 study.

An apolipoprotein B (apoB) test counts the number of LDL particles in the bloodstream as well as other particles that can contribute to clogged arteries and heart attacks. All of these so-called atherogenic particles carry a single apoB molecule but varying amounts of cholesterol. ApoB values are more closely linked to heart disease risk than LDL cholesterol. People with signs of an unhealthy metabolism-such as prediabetes, a big belly, or elevated triglycerides-are far more likely to have a high apoB.

Eating a variety of flavonoid-rich foods may offer greater protection against cardiovascular disease and cancer than eating only a few high-flavonoid foods, according to a 2025 study.

Lowering high levels of low-density lipoprotein (LDL), or "bad" cholesterol, is important for preventing and treating heart disease. The other cholesterol-high-density lipoprotein (HDL)-is often called "good" cholesterol, but this may be misleading. While some HDL particles gather excess cholesterol from the bloodstream and artery walls and deliver it to the liver where it's excreted, other particles are not good at this job, and some can even increase levels. People should focus on their LDL and not focus as much on HDL unless it's very low or very high.

Metabolic syndrome is defined as having at least three of the following: abdominal obesity, high blood triglyceride levels, high blood pressure, high blood sugar levels, and low HDL cholesterol levels. The condition significantly increases the risk for cardiovascular disease, diabetes, kidney disease, fatty liver disease, and sleep apnea. While each factor is problematic, the main driver is abdominal obesity, from visceral fat surrounding internal organs. The best way to reduce visceral fat is aerobic exercise, strength training, and a plant-based diet.

Older adults are especially vulnerable to heat-related ailments like heat exhaustion and heatstroke. The primary reason is biological, as aging bodies can't maintain a steady internal body temperature when external conditions change. Heart conditions and heart medications can add to the problem. Older adults can protect themselves from heat ailments by taking standard precautions during hot weather and recognizing the early symptoms of ailments so they can seek immediate treatment.

People with a family history of heart disease and high LDL cholesterol should consult their doctor about lowering their LDL levels to less than 70 milligrams per deciliter, which often means taking a statin, eating a healthier diet and exercising regularly.

A 2025 study found that in people who are overweight or obese, substituting standing and light walking in place of sitting may help improve blood levels of certain types of fats, including triglycerides and small, dense LDL cholesterol particles.

Statins are among the most-prescribed drugs in the United States, but some people are concerned about side effects. Lifestyle changes involving diet and exercise can help lower cholesterol enough to take a statin break
