Symptoms of a heart attack don't come from out of the blue. The more severe signs should signify a heart issue because they are unique. Heart attacks are not always like what we see in movies, where sudden chest discomfort sends a person tumbling to the floor -- symptoms vary with the individual. That is why you should be concerned about any signs or symptoms that may be related to the heart.
A painful or clenching feeling in the chest is a sign of a blocked cardiac artery or an impending heart attack. An affected individual may feel pressure in the chest accompanied by heaviness or crushing pain. The feeling can last for more than a few minutes and may be brought on by physical activity. If the pain is very brief and mild, lasting only a few seconds, it is probably not a symptom related to the heart. But severe and prolonged pain signify an emergency and the need to call 911.
