Sugary drinks—the biggest source of added sugar in the American diet—have been linked to higher levels of LDL cholesterol and other unhealthy fats in the bloodstream.

Arm curls, which strengthen your biceps, can be done with dumbbells or household items such as cans of soup or water bottles.

Microvascular disease refers to problems in the network of tiny blood vessels in the heart. Doctors suspect this condition in people who have angina (chest) pain with no evidence of blockages in the heart's larger arteries. In the most common form of microvascular disease, the inner walls of small arteries thicken, and the layer of cells closest to the blood lose their ability to expand and contract in response to the demand for increased blood flow, such as during exercise. In another form of the problem, vasospastic angina, muscles within the heart's arteries suddenly clamp down, causing a temporary spasm that blocks blood flow to heart muscle.

Some social media posts suggest that seed oils (such as canola, safflower, and sunflower oils) are responsible for a host of health problems, including obesity, diabetes, and even heart disease. But there's scant scientific evidence to support these claims. Seed oils are rich in unsaturated fatty acids, which are linked to a lower risk of heart disease when substituted for saturated fats (found mainly in animal-based foods such as butter, cheese, and meat).

About 20% of people have high blood levels of lipoprotein(a)—Lp(a) for short—a fatty particle that's like the evil twin of the more familiar LDL ("bad") cholesterol. Elevated Lp(a) which can double or triple risk of a heart attack and raise stroke risk, and is linked to problems with the heart's aortic valve. With new treatments that can lower Lp(a) on the horizon, cardiologists are now testing more people for this biomarker, which is not included in standard cholesterol tests.

Side effects from both older and newer cancer therapies can affect the heart and blood vessels, possibly causing serious, sometimes life-threatening complications. People diagnosed with any type of cancer should ask their doctor whether their planned treatment might lead to cardiovascular problems. Those ages 65 and older and anyone with risk factors for heart disease (such as high blood pressure or diabetes) may want to request a referral to a cardio-oncologist. These specialists focus on preventing and managing cardiovascular problems in people who are undergoing (or have completed) treatment for cancer.

Vasculitis is characterized by inflammation of the blood vessels, including the arteries, veins, and capillaries. The resulting damage can narrow, weaken, or scar vessels that supply just one body part or many different organs.

When a daily walk starts to feel humdrum, adding short bursts of fast walking (intervals) may help. Using earbuds to listen to music, books, or podcasts may also encourage people to stick with this heart-healthy exercise. Wearing appropriate attire, including a brimmed hat, slim-legged pants or shorts, and waterproof shoes may also keep walking enjoyable.

Five numbers give a thumbnail assessment of overall heart health and what factors people might need to address to lower the risk of a heart attack or stroke. These numbers offer ideal goals for most people, although targets vary for individuals based on age or other health conditions.

A major theme of the 2023 American Diabetes Association Standards of Medical Care guide is healthy weight loss. The new guidelines also encourage collaboration on meaningful lifestyle changes that help with sleep and health metric targets.
