What is a silent heart attack? Symptoms most people miss

Heart attacks are usually imagined as dramatic events, sudden chest pain, sweating, and a rush to the hospital. But in reality, many heart attacks happen quietly. These are called silent heart attacks, and they can be just as dangerous as the obvious ones. According to the US CDC, about 1 in 5 heart attacks are silent. The troubling part is that they go unnoticed until much later, sometimes only discovered during a routine check-up or after the damage has already been done.
