Get a leg up on deep-vein thrombosis

Leg pain may be caused by deep-vein thrombosis (DVT), a blood clot that forms in a deep vein, usually in the leg. Left untreated, the clot may break off, travel to the lungs, and cause blockage in a lung artery, known as pulmonary embolism (PE), which can be life threatening. Diagnosis of DVT and PE may include a review of symptoms, a D-dimer blood test, a leg ultrasound, or a chest CT scan. Both conditions are most often treated with direct-acting oral anticoagulants.

Varicose veins: More than a cosmetic concern

Varicose veins are not just unsightly and uncomfortable; they can also be harbingers of more serious conditions, including deep-vein blood clots and venous ulcers. Ablation therapies to eradicate varicose veins can lower these risks. People can also try simple strategies to prevent and improve varicose veins, including doing exercises that work their calf muscles, elevating their legs, and wearing compression stockings.

Boosting share of protein from plants in diet may lower heart disease risk

A 2024 study found that people who follow a diet with a higher ratio of plant-based protein to animal-based protein may have a lower risk for cardiovascular disease and coronary artery disease compared with individuals who eat a lower plant-to-animal protein ratio.

Practical pointers for pickleballers

Playing pickleball can boost cardiovascular health, but this popular sport can leave older players prone to injuries. Preventive strategies including taking a class to learn proper form; choosing supportive gear such as well-fitting shoes and sleeve braces; warming up before playing with squats, lunges, and heel raises; and doing lower-body strength-building exercises a couple of times per week.

Intensive lowering of blood pressure may protect people with type 2 diabetes from heart disease

People with type 2 diabetes may have greater protection from cardiovascular problems if they keep their systolic blood pressure (the first number in a reading) to 120 mm Hg or lower, according to a 2024 study.

A heart disease trigger that lurks inside bone marrow

A condition caused by spontaneous genetic mutations in bone marrow cells, known as clonal hematopoiesis of indeterminate significance (CHIP), is linked to an increased risk of cardiovascular disease. Some of these mutations are clearly related to inflammation, a well-known contributor to the buildup of fatty plaque inside arteries. Experts hope that future research on CHIP will eventually lead to genetically directed therapies to address the condition.

Is it safe to stop aspirin a year after a stent?

After a heart attack or stent placement, people typically take a combination of aspirin and another antiplatelet drug. After one year, the new standard practice is to stop the aspirin, in contrast to the previous practice of stopping the other drug.

Seeding doubt: The truth about cooking oils

Social media sources may share misleading information about canola, soybean, and other seed oils. But these oils, which consist mostly of unsaturated fat, can be a good source of heart-healthy fat when combined with whole, fresh foods rather than in processed foods like crunchy, salty, or sweet snack foods. Consuming unsaturated fat in place of saturated fat (found mainly in animal-based foods) is linked to a lower risk of heart attack and death from heart disease.

Lipoprotein(a): An update on testing and treatment

High levels of Lp(a)-a fatty particle similar to LDL cholesterol-may double or triple a person's risk of a heart attack. About one in five adults may have elevated levels, which also raises the risk of stroke and aortic stenosis. Unlike LDL, which rises with age and is influenced by diet and exercise, Lp(a) remains largely constant over a person's lifetime, so a one-time test suffices for screening. Lp(a) testing is becoming more common now that five promising new Lp(a) therapies are in development.

Shining a light on the diabetes–heart disease connection

Having type 2 diabetes doubles a person's odds of heart disease, and this risk may be present as early as 30 years prior to the diabetes diagnosis, according to a 2024 study. The findings support the long-held observation of the shared underlying causes of diabetes and heart disease. These include factors that contribute to both conditions, especially the tendency to accumulate fat in the middle of the body, known as abdominal obesity. This problem tends to occur in tandem with high blood pressure, unhealthy lipid levels, and elevated blood sugar-a cluster of signs and symptoms called metabolic syndrome.
