Brief brain attacks: Short symptoms, long consequences

A 2025 study finds that a first-time transient ischemic attack (TIA) can lead to the same long-term decline in thinking and memory problems as a full-blown stroke. Experts suggest cognitive testing after a TIA. People who have TIAs should take extra care to address risk factors for heart attack and stroke, such as high blood pressure and high cholesterol. Exercising regularly and staying socially active may help ward off cognitive decline.

Food additives and heart health

Ultraprocessed packaged foods and drinks contain thickeners, preservatives, and other additives to improve their taste, texture, appearance, and shelf life. But the high amounts of salt, sugar, and fat in these products are probably more concerning for a person’s health. Foods like sugary drinks and processed meats are the worst culprits. Eating a diet focused on whole, plant-based foods automatically lowers processed food intake and provides heart-protecting nutrients such as fiber, vitamins, and minerals.

The complex story of HDL cholesterol

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.

The many dimensions of a good night’s sleep

Getting a sufficient amount of sleep is vital for heart health, but sleep continuity, timing, and regularity may also be important. Irregularities in these lesser-known dimensions of sleep health are not considered problems unless they impair a person’s ability to function and quality of life. But emerging evidence suggest these sleep issues may affect cardiometabolic health. A sleep diary can help uncover potential issues.

Smarter, safer workouts with a wearable fitness tracker

Wearable fitness trackers like smart watches offer measurable and motivating data for exercise routines and safety, especially for people with heart conditions. Features include movement reminders, step counts (a daily total of 4,000 to 7,000 steps is considered beneficial), heart rate zones for exercise intensity, and measurements of heart rate recovery and variability to assess overall heart health. These tools can help optimize workouts and reveal potential issues.

What type of burgers are the healthiest?

Meatless burgers—which include plant-based meat alternatives like Beyond Burger and Impossible Burger and veggie burgers—are healthy replacements for traditional hamburgers. Those with the lowest amounts of saturated fat and sodium are the best options.

Extreme heat endangers older adults: What to know and do

The surge in heat waves and extreme heat poses serious health risks for everyone but is a particular worry for older adults. What can you do to manage heat-related risks, especially if you have existing health conditions or take certain medications?

Even a “weekend warrior” exercise pattern can lower heart risks

A 2025 study suggests that squeezing a week’s worth of exercise (150 minutes) into just one or two days — a “weekend warrior” pattern — is linked to the same heart benefits as daily exercise.
