Drops in air pollution linked to fewer heart disease hospitalizations

A 2024 study found that when air pollution levels decreased during a five-year period in Italy, so did hospitalizations for heart-related emergencies. The results suggest that reducing air pollution could lower the prevalence of heart disease.

Fixing a leaky tricuspid valve

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.

Calcium and heart disease: What's the connection?

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.

The hidden dangers of prediabetes

About 98 million Americans have prediabetes, in which the average amount of sugar (glucose) in the blood is high but not high enough to be diagnosed as diabetes. While people with prediabetes want to avoid getting diabetes, prediabetes can be dangerous on its own, as it increases the risk for cardiovascular disease, chronic kidney disease, and fatty liver disease. Controlling blood pressure, lowering LDL (bad) cholesterol, and managing glucose levels with weight loss, exercise, and diet offers protection against diabetes and these conditions.

Eating more plant-based fat may help your heart

Over a 24-year span, people whose diets favored plant-based fat lived longer than people who ate more animal-based fat, according to a 2024 study. The same distinction appeared specifically for deaths from heart disease.

Psychological factors can improve heart disease risk calculations

An online tool to predict heart disease risk might be more accurate if it included a psychological health assessment. Including depression screening results appears to strengthen the tool's ability to predict heart disease deaths.

Gratitude linked to longer life and fewer heart-related deaths

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.

Eating ultra-processed food may shorten life span among older adults

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.

Cutting meat intake by a third could reduce rates of 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.

More evidence links flu infection to heart attack risk

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