Peripheral artery disease: An update
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.
Heart-healthy dinner ideas from Harvard doctors
A healthy diet is a proven and powerful way to lower your risk of heart disease. Since dinner is often the main meal of the day, it's a good time to feature foods that support cardiovascular health. Four Harvard physicians share their favorite healthy dinners, which focus on lean protein (such as tofu, fish, and chicken) and a variety of vegetables.
Chronic stress may raise women's stroke risk
A 2025 study found that chronic stress is associated with higher stroke risks among women under 50, but not in men.
My calcium score is over 2,000. What's next?
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.
Cannabis and heart concerns: A closer look
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.
Wildfires: How to cope when smoke affects air quality and health
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.
Is your heart ready for sex?
Most men can resume regular sexual activity after a heart attack once they can engage in mild-to-moderate physical activity without experiencing marked fatigue, chest pain, or shortness of breath. For heart-related procedures like angioplasty with stent placement (to open a blocked artery and restore blood flow), coronary artery bypass surgery, or open-heart surgery, men should wait until surgical sites have fully healed before resuming sex. At the same time, men should address any lingering heart disease risk factors, such as high blood pressure and excess weight.
Calcium score, coaching, and statins may slow plaque buildup
For people with a family history of early heart disease, getting a coronary artery calcium (CAC) scan plus intensive coaching and a statin may help limit the progression of the plaque in their arteries, according to a 2025 study.
Drug to slow aortic stenosis shows early promise
A 2025 study found that a new type of medication may safely slow the progression of aortic stenosis (narrowing of the aortic valve) and delay the need for valve replacement.
Plant-based oils are better than butter for your heart
Trading about a tablespoon of butter per day for about two teaspoons of olive, soybean, or canola oil may help lower the risk of heart disease and premature death, according to a 2025 study.
