The evolution of cardiac surgery has dramatically lessened the risk of going under the knife. These days, some hospitals specialize in heart health only. However, it took a lot of steps to reach this point. Here’s a brief history…

When it comes to heart disease prevention, little has changed. High cholesterol is still a factor, as are smoking and obesity. Now when it comes to keeping your heart healthy, think of these four words – sleep, activity, diet and stress.

One thing scientists have learned after years of study is that cancer isn’t just one disease. While a lot more research needs to be done, scientists have made great strides. One area of focus is our immune systems. Another is genetics.
