One of the ketogenic diet's major perceived drawbacks is an increase in LDL, or so-called bad cholesterol. A new study, though, says that this cholesterol spike doesn't fit the conventional science in terms of its disease-causing ability.

If someone is afflicted with heart disease, it's important that their cardiac activity be monitored as accurately as possible. An experimental new wearable device is designed to make that happen, by copying the body structure of the starfish.

Engineers at Illinois' Northwestern University have developed the tiniest pacemaker you'll ever see. It's several times smaller than a regular pacemaker, and it's designed for patients several times smaller than the average pacemaker user.

A man has lived for more than 100 days with a maglev heart beating inside his chest. In a landmark moment, he was discharged earlier this year, becoming the first person in the world to leave the hospital with the device embedded in his body.

Aspartame has long been marketed as a guilt-free alternative to sugar in products like Diet Coke and sugar-free Jell-O. However, the sweetener has now been linked to an increased risk of heart attacks in mice. Should you ditch your fizzy drinks?

From fighting memory decline to warding off some cancers, drinking coffee continues to emerge as a way to improve your health. Now, a new study says that the time of day during which you drink your daily brew is key to boosting some of its effects.

A naturally occurring fat molecule reduced heart inflammation and scarring caused by diabetes, thereby improving cardiac function, according to new research. The findings open the door to developing a new treatment for diabetes-induced heart disease.

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.

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.

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.
