A heart can break, really

WSJ:

Dorothy Lee and her husband of 40 years were driving home from a Bible study group one wintry night when their car suddenly hit the curb. Mrs. Lee looked at her husband, who was driving, and saw his head bob a couple of times and fall on his chest.

In the ensuing minutes, Mrs. Lee recalls, she managed to avoid a crash while stopping the car, called 911 on her cellphone and tried to revive her husband before an ambulance arrived. But at the hospital, soon after learning her husband had died of a heart attack, Mrs. Lee's heart appeared to give out as well. She experienced sudden sharp pains in her chest, felt faint and went unconscious.

When doctors performed an X-ray angiogram expecting to find and treat a blood clot that had caused Mrs. Lee's symptoms, they were surprised: There wasn't any evidence of a heart attack. Her coronary arteries were completely clear.

Doctors eventually determined that Mrs. Lee had suffered from broken-heart syndrome, a name given by doctors who observed that it seemed to especially affect patients who had recently lost a spouse or other family member. The mysterious malady mimics heart attacks, but appears to have little connection with coronary artery disease. Instead, it is typically triggered by acute emotion or physical trauma that releases a surge of adrenaline that overwhelms the heart. The effect is to freeze much of the left ventricle, the heart's main pumping chamber, disrupting its ability to contract and effectively pump blood.

The phenomenon is a "concussion" of the heart, says Scott Sharkey, a cardiologist at Minneapolis Heart Institute. "It's really a heart attack which is triggered by stress rather than by a blocked artery," he says.

I think more accurately it should be described as a heart attack to an otherwise healthy heart caused by stress. I think many heart attacks are triggered by stress for people with unhealthy hearts. It is a fascinating finding, that should be no real surprise to anyone who listens to country music or who has experienced a loss of someone they love.
