The danger of “silent” heart attacks
As many as half of all heart attacks go unrecognized — and their long-term consequences can be serious. Most people don’t realize that they could have a heart attack without even knowing it. Although these are commonly referred to as “silent” heart attacks, a more accurate term may be “unrecognized” heart attack, says cardiologist Dr. David Morrow, director of the cardiac intensive care unit at Harvard-affiliated Brigham and Women’s Hospital.
