A silent heart attack is like any other heart attack, except it occurs without the usual symptoms. In other words, you may not even realize you’ve experienced a heart attack.
In fact, research from Duke University Medical Center has estimated that as many as 200,000 Americans experience heart attacks each year without even knowing it. Unfortunately, these events cause heart damage and increase the risk of future attacks. Silent heart attacks are more common among people with diabetes and in those who’ve had previous heart attacks.
