Slow Heart Attack Assessment View Calculator No one doubts a heart attack is happening when it is sudden and intense. But most heart attacks begin slowly, with mild pain or discomfort. Most people do not recognize a slow heart attack, happening to themselves or someone else, and wait too long to get help. By knowing and recognizing the symptoms of a slow heart attack, you could prevent someone from having a massive, sudden heart attack. Almost all heart attack victims experience chest pain or discomfort. And both men and women may have some of the other symptoms, but women are more likely to experience other symptoms along with the chest discomfort. If you or someone with you has chest discomfort that lasts several minutes, or has chest discomfort with one or more of the other heart attack signs, call 9-1-1 and get to a hospital immediately. Nearly 1.1 million Americans have a heart attack each year and nearly half of those are fatal. Half of these deaths occur within 1 hour of the start of symptoms and before the person reaches the hospital. Take this quick assessment to learn the symptoms of a slow heart attack and help you determine if you or someone you care about has had a slow heart attack that may lead to a sudden heart attack.
