About 66% of adults over age 70 still take antihypertensive medication even though they now have low pressures, says a study from the University of Kent in the United Kingdom. Researchers say this exposes adults to medication side effects like dizziness and falls. 

Transient ischemic attacks, or TIAs, can signal an impending stroke, but prompt care can minimize damage.

Have you ever experienced a brief episode when your body seemed to be a little off—your vision was blurry, your speech slightly slurred, or one side of your body felt weaker than the other? If so, you may have experienced a transient ischemic attack (TIA), says Dr. Natalia Rost, a neurologist at Harvard-affiliated Massachusetts General Hospital. She notes that many women may assume they have suffered a migraine and get back to life as usual once the episode has passed. In fact, a TIA is a serious medical issue and warrants getting immediate treatment.

Why white matter really matters

A daily aspirin may help defend against heart disease, but it should still be used with caution.

Aspirin tablets have been a staple of home medicine cabinets and first-aid kits for nearly 100 years. Long before that, people chewed willow tree bark, which contains aspirin-like compounds, to treat a variety of ailments. On top of being an excellent painkiller and fever reducer at its standard dosage, aspirin dramatically reduces the risks for a second heart attack and certain types of stroke when taken daily at a low (81-mg) dose. Research also suggests that aspirin might help limit the growth of colorectal cancer and possibly inhibit other cancers as well, but more research in this area is needed.

These benefits, coupled with the fact that aspirin is both cheap and relatively safe, have led the U.S. Preventive Services Task Force (USPSTF) to recommend that even some healthy people take a daily aspirin to ward off future disease. But figuring out exactly who is likely to benefit most from this therapy is a more complex calculation, says Dr. Michael Gaziano, a professor of medicine at Harvard Medical School and cardiologist at Brigham and Women's Hospital.

Fasting for eight to 12 hours before a cholesterol test doesn’t seem to be necessary. But for now, people should continue to follow their physicians’ advice on this matter.

Nearly half of all heart attacks are silent, meaning they are not associated with any reported symptoms. Silent heart attacks, which can be detected on electrocardiograms, should prompt people to follow the same prevention steps as with a more typical heart attack.

Fellow exercisers may keep you motivated, and learning proper form can help you avoid injuries.

Is your solo walking or cycling routine getting a little humdrum? Maybe it's time to try a group fitness class at your local gym or community center. Working out with others in a class led by a trained instructor may help you stick to an exercise routine, which is a vital part of keeping your heart healthy.

"We know that in a broad sense, the more fit you are, the longer you live," says Dr. Meagan Wasfy, a cardiologist at the Cardiovascular Performance Program at Harvard-affiliated Massachusetts General Hospital. Exactly how you achieve that fitness doesn't seem to matter—the main thing is making it happen. Group fitness classes, which come in a wide range of styles and intensities, may offer certain advantages toward that goal.

People who are more physically fit in their mid-to-late 40s may be less likely to have a stroke after age 65 than those who are less fit.

People who eat at least four servings of whole-grain foods per day appear to have a 23% lower risk of dying of cardiovascular disease compared with people who eat little or no whole grains.

Home sleep tests to diagnose obstructive sleep apnea (OSA) may reliably detect the disorder even if a sleep specialist is not involved. Marked by loud snoring and breathing lapses during sleep, OSA can increase the risk of cardiovascular disease.

Often referred to as a ministroke , a transient ischemic attack, or TIA, often lasts only minutes, but acts as a warning for a potential full stroke.

Stumble walking across the room? You simply aren't watching your step. Forget a name or can't get out the right words? It's just a fuzzy senior moment. Feeling a little dizzy? You only need to sit down for a second.
