Calcium supplements, often taken to maintain bone health and prevent osteoporosis, appear to be linked to an increased risk of heart attack, a large study revealed.

Heart failure patients bored of the typical cardiac rehabilitation exercise machines can get the same or better benefit with a new activity.

Teens struggling with their weight may already have heart damage. Overweight adolescents without symptoms of heart disease are already suffering cardiac damage.

One in three adults around the world has elevated blood pressure, a World Health Organization (WHO) report has indicated. The report also emphasized increasing rates of diabetes and obesity.

Researchers already knew that overweight moms generally gave birth to children who became overweight too. But the health impact of obesity during pregnancy doesn't stop there.

An individual's risk of sudden cardiac death isn't just tied to whether they are overweight or obese. It's also associated with the specific part of the body carrying the added weight.

With age and conditions such as heart failure, it's not uncommon for individuals to experience muscle wasting. Physical activity appears to be key to reversing that trend while also reducing inflammation.
