Find a Valentine, for your health: People can actually die from broken hearts, says The Wall Street Journal. Broken-heart syndrome looks like a heart attack, but occurs in patients without heart disease. Instead it is brought on by acute emotion or physical trauma that releases a rush of adrenaline to the heart, freezing up the left ventricle. It often affects patients who have lost a loved one, and is most common in postmenopausal women. The syndrome is responsible for 1 to 2 percent of all heart attacks.
