Drinking coffee and tea linked to lower stroke risk

People who sip several daily cups of both coffee and tea may be less likely to have a stroke than people who don't drink either beverage.

How stimulants may affect your heart

Stimulant medications, which are usually prescribed to treat attention deficit disorder in children, are being prescribed increasingly to older adults. These drugs may cause a short-term spike in the risk of heart-related problems, including heart attacks, strokes, and arrhythmias. Dietary supplements that promise weight loss or better physical or mental performance may contain prohibited, unlisted, and potentially dangerous stimulants.

Five hours of weekly exercise linked to fewer cancer cases

A study published online Oct. 4, 2021, by the journal Medicine & Science in Sports & Exercise found that about 46,000 U.S. cancer cases per year can be attributed to getting less than 300 minutes of moderate-intensity exercise per week.

Drinking both coffee and tea linked to lower risks for stroke and dementia

A study published Nov. 16, 2021, in PLOS Medicine found that drinking two to three cups of coffee as well as two to three cups of tea per day was associated with substantially lower risks for dementia and stroke, compared with drinking no coffee or tea.

Do older adults benefit from blood pressure treatment?

A study published online Aug. 26, 2021, by The Lancet found that blood pressure treatment protects against heart attacks, strokes, and other major cardiovascular disease problems in people up to age 85 and possibly older. For people younger than 75, the study confirmed that people taking blood pressure medicines had 10% to 20% fewer cardiovascular disease problems. For people 75 to 84, there still was a 10% reduction. For people older than 85, the results were mixed, but there still appeared to be a benefit from blood pressure treatment.

Exercise may heal the heart as well as prevent future problems

Exercise may help to reverse some types of heart damage. Not only can workouts prevent heart problems, but it may help to improve conditions that may raise risk for cardiovascular events. A 2021 study, for example, showed that a yearlong exercise program helped improve heart health in people who were at increased risk for heart failure.

Is there such a thing as a silent stroke?

It is possible to experience a stroke without symptoms. Addressing cardiovascular risk factors can help lower the risk.

What's the best blood pressure target for older adults?

For people over 60, aiming for a blood pressure target below 130/80 mm Hg may prevent more cardiovascular problems than aiming for the higher target suggested by some physicians. Some feared that the more intensive treatment required to reach the lower target might cause more adverse side effects (such as dizziness and falls) in older people. But side effects do not appear to differ among people taking intensive versus standard therapy.

Salt substitute associated with lower rates of stroke, death

A large study published online Aug. 29, 2021, by The New England Journal of Medicine found that people who used a salt substitute on their food had a lower risk of stroke, heart attack, and early death, compared with people who used regular salt.

Saturated fat and low-carb diets: Still more to learn?

Low-carbohydrate diets have been popular for many years, but due to the high amounts of saturated fat, doctors and nutritionists worry about possible increased risk of cardiovascular disease. A study comparing three diets found that eating a high-fat diet did not necessarily raise heart risk, but the types and quantities of food make a difference.
