Nearly Half Of All Heart Attacks Occur Without You Even Knowing It

A heart attack might not hurt as much as you think—in fact, you might not even know you had one, according to research from the Wake Forest School of Medicine.

In the study, researchers added up the number of clinically-diagnosed heart attacks and “silent” heart attacks—events that were undiagnosed at the time but were confirmed by electrocardiogram (EKG) afterwards—that occurred in more than 9,000 people during a 9-year follow up.

They discovered that 45 percent of all the heart attacks were silent.

How Diabetes May Raise Your Fatal Heart Attack Risk By 50 Percent

Your heart health depends on more than what’s going on in your chest: Having diabetes increases your chances of dying from a heart attack, a new study from the University of Leeds suggests.

After tracking more than 700,000 people for 8 years, the researchers discovered that those with diabetes were 56 percent more likely to die from a STEMI heart attack—where your coronary artery is completely blocked—and 39 percent more likely to die from a NSTEMI heart attack—where your coronary artery is partially blocked—than people without the condition.
