In 2024, the FDA approved two catheter-based devices for treating a leaky tricuspid valve. Both relieve symptoms and improve quality of life for people with moderate to severe tricuspid regurgitation, which affects about 4% of people ages 75 and older. One device is a modification of a system to treat mitral valve regurgitation that works by bringing the valve leaflets together at the areas of most severe leakage. The other device delivers a new valve made of cow heart tissue, which is commonly used in surgical valve replacements.

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.

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

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

Older adults who consume ultra-processed foods as a substantial part of their diet have a higher risk of early death than those who eat less of these foods.

Atrial fibrillation and supraventricular tachycardia are rapid, abnormal heart rhythms that originate in the upper part of the heart. But they tend to arise at different ages, and they require different treatments.

Gratitude has the power to boost well-being, improve sleep, lessen depression, and help heart health. Now new data from the long-term Nurses' Health Study shows that it may extend lives. How can you jump start a gratitude practice in your life?

Body roundness index, which is calculated based on a person's height, waist, and hip size, might be a more accurate measurement than body mass index for predicting weight-related health risks, according to a 2024 study.
