In a 2024 study by Harvard researchers, people who reported feeling persistently lonely had a 56% higher risk of experiencing a stroke compared with people who did not report feelings of loneliness.

New research has found that Americans are now dying from heart failure at a higher rate than 25 years ago, making prevention more important than ever. The best strategy to lower one's risk from heart failure is to address its top underlying contributors: high blood pressure, abnormal blood lipid levels, and weight gain. Addressing these risk factors can also protect against developing coronary artery disease and diabetes, two of the main medical conditions that cause heart failure.

Mobile ECG devices are small, handheld devices that people can use to record a simple ECG at home. They are designed to detect heart rhythm disorders such as atrial fibrillation.

Contrary to previous recommendations, people who think they are having a heart attack or stroke should not take an aspirin on their own. Their symptoms might be caused by a different problem that might be made worse by taking aspirin.

High levels of lipoprotein(a), or Lp(a)-a variant of LDL (bad) cholesterol- may triple the risk of a heart attack, even among healthy people with no other known risks for heart disease.

People with hypertension who monitor their blood pressure at home may be able to successfully self-titrate their blood pressure medications, a 2024 study suggests. First, they need to know their target blood pressure. Readings that remain above goal requires consultation with their doctor to create a plan for better BP control, such as specific steps for medication self-titration.

Getting an electrocardiogram (ECG) prior to undergoing noncardiac surgery should be the exception rather than the rule. About half of surgeries are low-risk and pose very little danger for the heart. Asking about a person's symptoms during physical activity-for example, whether they can walk up a flight of stairs without feeling winded-is a better gauge of their risk than the findings from an ECG. But presurgical ECGs make sense for older, inactive people with heart disease. The results can reveal signs of reduced blood flow to the heart or an unstable electrical heart rhythm that may require treatment before surgery.

Dried fruits such as raisins, dates, and figs are good sources of potassium, fiber, and other nutrients. A serving size of these calorie-dense treats is just a quarter-cup.

Compared with white rice, brown rice contains much higher amounts of fiber, certain B vitamins, magnesium, potassium, and iron. Research suggests that swapping white rice for brown rice may improve blood sugar levels and help with weight control.
