Is snow shoveling safe for people with heart disease?

Snow shoveling can be risky for people with heart disease because (1) the activity requires a lot of physical effort, and (2) cold temperatures constrict arteries. Both factors can raise the risk of a heart attack in people with narrowed heart arteries.

Heart and soul: Spirituality in cardiovascular care

Most hospitals have chaplains who can provide emotional and spiritual support to patients and their families during challenging medical situations, such as impending heart surgery, a worsening bout of heart failure, or cardiac arrest. Spiritual care, which has been linked to improved health outcomes, encompasses but does not necessarily include formal religious practices. It aims to help people explore sources of comfort and hope while coping with the challenge of a diagnosis.

Short bursts of intense exercise may benefit stroke survivors

For stroke survivors, workouts that alternate high- and low-intensity exercise (known as high-intensity interval training or HIIT) may boost fitness more than moderate-intensity workouts.

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.

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.

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.

A nondrug approach to lower blood pressure

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.

Sign up for a Turkey Trot

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.

Why choose bypass surgery over stents?

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.
