Cannabis use is rising among older adults, who mostly use cannabis edibles such as gummies for relaxation and sleep. While smoking cannabis may raise heart attack risk, the cardiac effects of consuming cannabis in food or drinks are less well understood. Taking too much cannabis can lead to a panic attack, which can cause a pounding heart or palpitations. People who use cannabis should take it only as needed to relieve symptoms, using the lowest possible dose.

High blood pressure means that blood pushes against artery walls more forcefully than normal. Women's blood pressure is typically lower than men's until around age 60. An estimated 41% of women develop high blood pressure after menopause. High blood pressure increases people's risks of heart attack, stroke, kidney disease, and other problems. Factors that increase women's risk of high blood pressure at midlife include menopause, elevated sympathetic nerve activity, weight gain and redistribution, stress, and genetics.

Fatty plaque that accumulates in the arteries of the legs, known as peripheral artery disease (PAD), can cause a painful, crampy sensation in the legs during walking. Smoking, obesity, diabetes, high blood pressure, and elevated cholesterol increase the risk of PAD, which affects nearly one in three people over age 75. Beyond quitting smoking, regular walking is the best treatment for PAD. A 2025 study found that semaglutide (Ozempic, Wegovy) may help people with PAD walk farther with less pain.

People with very high calcium scores (over 1,000) have a risk of heart attack or stroke similar to those who have already had a heart attack. They should take cholesterol-lowering drugs to bring down LDL levels and possibly undergo additional testing.

A 2025 study found that a pill version of the drug semaglutide, marketed as Rybelsus, can lower the risk for serious heart problems in people who have diabetes as well as cardiovascular disease, kidney disease, or both.

Wildfire smoke contributes greatly to poor air quality, and as wildfires become more frequent due to climate change and drier conditions, more of us and more of our communities are at risk for health harms. Here are ways to cope.

A 2025 study found that people who are sedentary for 10.6 hours per day or more may face a higher risk of heart failure or dying from heart disease-even if they follow recommended exercise guidelines. Uninterrupted sitting has harmful effects on metabolism, leading the body to burn fewer calories and less fat. It can also cause blood sugar levels to rise, triggering the release of insulin, the hormone that regulates blood sugar. Over time, sedentary habits cause the body to become less sensitive to insulin. The resulting insulin resistance promotes inflammation, a key player in the buildup of fatty plaque inside arteries.

A 2025 research review suggested that women with certain gynecological disorders, such as polycystic ovary syndrome, endometriosis, heavy periods, and irregular menstrual cycles, have higher risks of cardiovascular and cerebrovascular disease.

Cushing's is marked by elevated blood levels of the hormone cortisol. Far more common in women, the condition is categorized as a disease or syndrome based on what factors trigger it, which can include using corticosteroids or having a tumor on the brain's pituitary gland or elsewhere. Symptoms include a swollen face, excess belly weight, fatigue, a fatty hump between the shoulders, stretch marks, easy bruising, and slow wound healing. Cushing's can also lead to health problems such as cardiovascular disease, bone loss, and diabetes.
