Even a "weekend warrior" exercise pattern can lower heart risks

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.

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.

Do you have metabolic syndrome?

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.

Midlife pressure surge

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.
