Following a Mediterranean eating pattern is linked to longer life-a finding at least partly explained by such heart-related improvements as decreases in body mass index, inflammation, triglyceride-rich lipoproteins, and insulin resistance.

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.

Compared with people who eat out frequently, people who eat meals made at home tend to weigh less, have healthier cholesterol and blood sugar values, and are less likely to develop diabetes. Lack of time, not lack of skills, may be the biggest barrier. Tips for creating healthy, home-cooked meals include smart ways to stock a pantry, fridge, and freezer with legumes and whole grains. For example, people can use an electric pressure cooker to make a dozen or more half-cup servings of brown rice that can then be stored in the freezer. This technique, called batch cooking, can be used with dried beans as well as with flavor enhancers such as minced garlic and ginger.

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.

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.

Older adults who received interpersonal exercise coaching (which included connecting with peers to learn and share information) improved their step counts and activity levels more than seniors who received intrapersonal coaching that was mostly self-focused, a 2024 study found. Finding an exercise partner (a spouse, friend, or neighbor) may help inspire people to exercise more. A group exercise class may provide the same benefit, in addition to providing structure, a trained instructor, and camaraderie.

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.

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.

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.
