If I am right in assuming that you are female, you should know and inform others that womens symptoms for heart attack are different from mens . They are not at all obvious, and usually do not include left arm pain. What they do commonly experience in an extreme fatigue that they can t fight off. They will often think they are just tired and need rest only to pass away in their sleep. There is very little information out there to educate women on the symptoms of heart attack, but I have found this list; It s vital to be able to recognize the symptoms of a heart attack. Chest discomfort, pressure or burning Chest or abdominal discomfort or pain spreading to the shoulders, neck, arm, or jaw Discomfort or pain between the shoulder blades * Shortness of breath * Sweating Nausea or vomiting * Indigestion or gas-like pain * Dizziness or fainting Unexplained weakness or fatigue Sense of impending doom
