Dark chocolate has been extensively studied for its cardiometabolic health benefits, but findings have been inconsistent, spurring heated debates over whether this treat has pros that outweigh the cons. Now, new research puts dark chocolate back on the table, quantifying its impact on type 2 diabetes risk and weight gain in a study of nearly 200,000 US adults.

Being sedentary at work led to lower blood pressure than standing to work for long periods. The findings are from a new study that also found that prolonged standing can be harmful to the heart and circulation.

In an analysis of the sleep habits of over 72,000 people, researchers identified a particular pattern that can dramatically spike the risk of major cardiovascular problems. The good news is that the pattern is relatively easy to avoid.

Studies presented at a recent American Heart Association conference have confirmed the heart health benefits provided by the new anti-obesity drugs, semaglutide and tirzepatide, and how lifestyle interventions for weight loss affect heart biomarkers in diabetics.

Finding time to exercise each day is a challenge for many people, but a new study of nearly 15,000 men and women has discovered that adding just five minutes of daily activity that gets your heart rate up is enough to lower your blood pressure.

Sticky plaques building up on the walls of your blood vessels can lead to heart attacks and strokes. Now, a new nanoparticle infusion therapy has been found to break down these plaques safely in tests in pigs.

A new injectable, temporary pacemaker could help correct a heart arrhythmia in an emergency. This nanoparticle gel can regulate the heart’s electrical signals for up to five days before dissolving harmlessly in the body.

Smoking, obesity, and stress. They're all common causes of damaging cardiac events. However, a just-published study says a new culprit should be added to the list of the risks that can hurt our hearts: constipation.

While there has been a general consensus that olive oil and other plant-based fats are better for you than butter, scientists have now put it beyond doubt, combining diet-intervention and previous cohort research to assess serious disease risk.

An existing drug has significantly improved the symptoms of obstructive sleep apnea – so much so that many trial participants stopped using CPAP machines. It stands to be the first therapeutic to effectively treat the condition, which affects millions.

Even brief periods of anger caused by triggering memories can negatively impact our blood vessels' ability to relax. That's the finding of a new study that could have implications on how we look at heart attack and stroke risk.
