New research suggests black and white men may be more likely than women to have a silent heart attack — one that doesn’t trigger symptoms such as chest pain and cold sweats — but women may be more likely to die from a silent heart attack.
The findings, published Monday in the journal Circulation, also showed that blacks may fare worse than whites, although researchers point out the number of blacks in the study may have been too small to be certain.
Researchers analyzed data from about 9,500 U.S. black and white men and women. More than half were women and about 20 percent were black.
Researchers have known that silent heart attacks represent 22 percent to 60 percent of all heart attacks. In the new study, more than 45 percent of heart attacks were silent.
