cardiac risk

Maybe it's not really cholesterol from that big, juicy steak that's linked to heart disease. Instead, it could be a compound in red meat called carnitine, which does a number on our gut bacteria if we eat too much meat too often, suggests intriguing new research.

It doesn't matter whether you spend winter shoveling snow in Massachusetts or walking on the beach in California, you're more likely to die of heart-related issues in the winter months, a new study finds.

Apparently, looks really do matter, at least when it comes to health. A new study finds that if you look old for your age, it could signal that your heart is aging too quickly as well.

If you're 45 and fit - meaning you don't smoke and don't have diabetes, high blood pressure or high cholesterol - don't feel too smug. You still have a one in three chance of developing heart problems, including stroke, by the time you're in your 80s or 90s, new research finds.
