People who climb more than five flights of stairs—about 50 steps—daily may lower their risk of cardiovascular disease, according to a 2023 study.

Planks are an isometric exercise, in which the muscles contract but do not move. They are a great way to strengthen muscles in the abdomen, back, legs, shoulders, and arms.

For people with chronic coronary disease who do not have symptoms, new guidelines recommend against routine testing with cardiac CT angiography, echocardiography, and stress testing. The results are unhelpful—and in some cases harmful. Unclear results often general additional testing or unnecessary procedures, including some that expose people to radiation for no reason. In addition, the tests add expense without any corresponding benefit, and these costs are increasingly being passed back to patients, in the form of copayments or higher premiums.

Palliative care for heart failure aims to improve quality of life for patients and their families by addressing physical symptoms, and also emotional, psychosocial, and spiritual issues. This may include treating anxiety and depression in patients and supporting caregivers, who may be dealing with stress and worry. Palliative care also includes talking with patients about their personal goals and what matters most to them, which can help guide their care as the illness progresses.

Despite statements like "promotes heart health" on the labels of fish oil supplements, multiple randomized trials show no evidence of heart-related benefits from using these products. In addition, manufacturing methods might make the products either useless or even harmful. The supplements do provide omega-3 fatty acids, but people can get these essential fats by eating two servings of fatty fish weekly or following a vegetarian diet rich in healthy oils, nuts, and seeds.

Products that encourage healthy eating or exercise can make good holiday gifts for family and friends. Examples include cooking gadgets (such as a food chopper or high-quality knife), a gift basket of fresh fruit or Mediterranean-inspired treats, or home workout equipment (such as dumbbells, resistance bands, or sports-related gear).

Isometric exercises that engage the muscles without movement—such as wall squats and planks—may help lower blood pressure more than other types of strength training. Experts have speculated about a possible mechanism: During isometric exercise, clenched muscles temporarily constrain blood flow. The following surge of blood may stimulate the release of factors that help relax the vessels and ultimately contribute to a reduction in blood pressure.

Ejection fraction is the fraction (expressed as a percentage) of the blood that the heart "ejects" out to the rest of the body when it contracts. Low ejection fraction signals one form of heart failure. An echocardiogram is the standard test to measure ejection fraction.

Thousands of miles of veins throughout the body bring blood to the lungs to pick up oxygen and nutrients, and get rid of carbon dioxide before returning to the heart to be pumped out again. How do veins work, what problems can occur, and how can you keep these vital blood vessels healthy?
