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.

Older people with atrial fibrillation are sometimes advised to stop taking clot-prevention drugs due to fears about bleeding. But a 2025 study suggests that the risk of stroke and heart attack from stopping the drugs outweighs the risk of bleeding.

Telehealth visits combined with home monitoring may be an effective way to help people reach and maintain their blood pressure goals, according to a 2025 study.

Coronary computed tomography angiography (CCTA) creates a 3D image of the heart and its blood vessels, revealing both obstructive and nonobstructive plaque. Most heart attacks occur when smaller, nonobstructive plaques rupture and form a clot that triggers a heart attack. Used to assess people with stable angina, CCTA may prevent heart attacks by improving how cardiologists find and treat heart disease.

A 2025 studyfound that intermuscular fat—fat stored within muscle tissue—may increase a person's risk of heart disease.

People who aggressively lower their high blood pressure not only help their heart health, but also may protect their brains from cognitive decline in the process, according to a 2025 study.

Evidence published in 2025 suggests that 15 million people in the United States are at risk for developing heart failure, a condition in which the heart doesn't pump well enough to meet the body's needs. The estimate was determined with improved tools to calculate risk, called the PREVENT equations. Like previous methods, the equations consider age, blood pressure, cholesterol levels, and smoking history. But the PREVENT equations remove race (an unreliable predictor) and add additional aspects of health.

About 25% of people have a common heart variant called a patent foramen ovale (PFO), a flaplike opening between the heart's upper chambers. In people with the condition, venous blood can leak across the heart from the right atrium to the left atrium, bypassing the lungs. If that blood contains a clot, it can travel directly to the arteries that send blood throughout the body. A stroke can occur if that clot lodges in an artery supplying the brain. In people prone to blood clots, a PFO raises the risk of stroke and dementia.

A daily serving of cheese is linked to a lower risk of heart disease, stroke, and death from cardiovascular disease. But it's best to pair cheese with foods like whole-grain crackers or salad instead of combining it with refined carbohydrates and meat, such as cheese on burgers or pizza. Health-promoting fermentation products may counteract the saturated fat and sodium found in cheese.

Substituting potassium-containing salt substitutes for regular salt can help lower blood pressure as well as the risk of stroke. But people should also check the sodium content in foods and eat more potassium-rich produce.
