Renal denervation, a nondrug treatment for uncontrolled high blood pressure, works by disrupting some of the nerves surrounding the renal arteries, which supply the kidneys. Two systems are FDA-approved for people whose blood pressure remains high despite lifestyle changes and medications. Renal denervation lowers systolic blood pressure by an average of 8 to 9 points—about the same as what people get with a single blood pressure drug. But the response varies widely; some people experience more dramatic drops, while others have no response.

People sometimes wonder if the calcium they consume affects their calcium score, a test that measures calcium in the heart’s arteries to predict heart disease risk. But a 2024 study linked higher calcium intake to a lower risk of heart calcifications. Calcium helps lower blood pressure, possibly by improving the function of the lining of blood vessels. Older adults should make sure they’re getting the recommended amount of calcium in their diets. Good sources include dairy products, tofu made with calcium sulfate, almond or oat milk, canned sardines or salmon, collard greens, and kale.

People who have stable angina despite taking medications can be treated with stents or bypass surgery. The best choice depends on the location and complexity of the artery blockages and other health conditions.

People seeking motivation to be more active and connected to their community might consider signing up for a Turkey Trot, a race or “fun run” held on Thanksgiving morning. Most events are 5 kilometers (3.1 miles), and participants can walk all or part of the course. Many feature ways to support a local community charity.

The Brain Care Score is a quiz developed to help people identify proven, actionable steps to lower their risk of stroke, dementia, and depression. It includes four physical components (blood pressure, blood sugar, cholesterol, and body mass index); five lifestyle components (nutrition, alcohol intake, smoking, aerobic activities, and sleep); and three social-emotional components (stress management, social relationships, and meaning in life). Each response is given a point value, with the highest possible score totaling 21. Higher scores mean better brain care.

Heart attack symptoms can be severe or subtle. The underlying process that causes a heart attack can differ, and people may experience significant heart damage or little to none. Doctors diagnose a heart attack based on symptoms, a person’s cardiovascular risk profile, electrocardiogram findings and the blood troponin level. Troponin is a protein released when heart damage occurs. Immediate and long-term treatment depend upon the type of heart attack and its impact on heart function.

A 2024 study suggests that older women with higher scores on tests to assess gratitude may live longer than those with lower scores. Most of this benefit seems to come from preventing deaths from heart disease.

A diagnosis of influenza (flu) was linked to a sixfold risk of heart attack over the following week, according to a 2024 report.

A 2024 report suggests that rates of cardiovascular disease, diabetes, and colon cancer would fall substantially if people ate less red and processed meat.

Many yard and gardening tasks—including raking and mowing —require enough effort to count as moderate-intensity exercise. Chores like digging and bagging leaves also help strengthen muscles. A 2023 study found that gardening helps increase physical activity levels, encourages greater fiber intake, and lowers stress and anxiety—all of which reduce the risk of heart disease.
