A 2025 study suggests that squeezing a week's worth of exercise (150 minutes) into just one or two days - a "weekend warrior" pattern - is linked to the same heart benefits as daily exercise.

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 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.

Metabolic syndrome is defined as having at least three of the following: abdominal obesity, high blood triglyceride levels, high blood pressure, high blood sugar levels, and low HDL cholesterol levels. The condition significantly increases the risk for cardiovascular disease, diabetes, kidney disease, fatty liver disease, and sleep apnea. While each factor is problematic, the main driver is abdominal obesity, from visceral fat surrounding internal organs. The best way to reduce visceral fat is aerobic exercise, strength training, and a plant-based diet.

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.

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.

A 2025 study found that chronic stress is associated with higher stroke risks among women under 50, but not in men.

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.

Smart watches can monitor different parameters simply by measuring a person's pulse and body movements. Potentially helpful features include those to detect very low or high heart rates, irregular heart rhythms, and breathing disruptions during sleep.
