But they're still deadly
Silent
heart attacks, which have no symptoms but still involve a loss of blood flow to
the heart, make up 45% of all heart attacks and triple the chances of dying
from heart disease, according to a study published
Monday.
The
study, published in the American Heart Association’s publication Circulation, found
that silent heart attacks make up nearly half of all heart attacks and increase
the chance of death by all causes by 34%. The study, which examined almost
1,000 patients, also found that silent heart attacks are more common in men but
more deadly in women.
Silent
heart attacks are often undetected by the patient, and may not be noticed until
patients have an electrocardiogram to measure their heart’s electrical
activity.
“The
outcome of a silent heart attack is as bad as a heart attack that is recognized
while it is happening,” said lead author Elsayed Z. Soliman in a statement accompanying
the release of the study. “And because patients don’t know they have had a
silent heart attack, they may not receive the treatment they need to prevent
another one.”
