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.

Strokes fall into two main categories: ischemic (which result from a blockage inside one of the brain's arteries and account for 87% of all strokes) and hemorrhagic (also known as bleeding strokes, usually from a ruptured blood vessel). Three main types of ischemic strokes are those that result from atherosclerosis in a large artery supplying the brain (large-artery atherothrombotic strokes); those caused by clots in the heart that travel to the brain (cardioembolic strokes); and those in the brain's smallest vessels (small-vessel strokes).

Most people don't need to fast before a lipid test because the difference between LDL cholesterol values when fasting or not fasting is very small. But people who have had high triglyceride levels should fast prior to the test.

Intensive blood pressure control that lowers systolic blood pressure (the first number in a reading) below 120 points may lower the risk of cognitive impairment or probable dementia.

Engaging in prosocial, altruistic behavior that benefits other people-such as doing volunteer work, giving money to charity, or performing small acts of kindness-may be beneficial to cardiovascular health. Possible mechanisms include reductions in stress and blood pressure. Volunteering has also been associated with improvements in heart-related risks, including increased step counts and less depression.

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.

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.

A 2024 study suggested that even five minutes of additional vigorous daily exercise could lower blood pressure.

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.

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.
