Most people are knowledgeable about the more common signs of a heart attack such as chest pain, pain radiating down the left arm and shortness of breath. However, there are many other subtle signs that can warn of an impending heart attack. These signs can often differ between men and women. Knowing the signs of a heart attack and getting medical attention immediately can help to save your life.Signs of Heart Attack in MenA man experiencing a heart attack is more likely than a woman to have the classic heart attack signs. Severe chest pain is an emergency situation and requires immediate evaluation by a doctor. Men may also experience an irregular heartbeat, pain in the upper abdomen, indigestion, profuse and unrelenting perspiration and nausea. Often, an extreme sense of anxiety is present. Any combination of these symptoms should be evaluated as soon as possible.Signs of Heart Attack in WomenWomen can experience very different symptoms. Women tend to experience symptoms days or weeks before the heart attack strikes. These warning signs can include weakness, fatigue, a sense that something is "wrong", jaw pain, shoulder pain and difficulty sleeping. Women may also experience the same warning signs as men once the attack gets closer. Since women have a much lower rate of heart attacks than men, it is important to inform the doctor if you suspect you are having a heart attack. Many doctors may overlook the more subtle symptoms in favor of another ailment.What to Do During a Heart AttackThe most important thing to do during a heart attack is to stay calm. Panicking can cause the blood to pump faster and worsen the condition. Taking an aspirin-based drug is thought to improve survival rates if taken at the onset of the heart attack; discuss any aspirin regimen with your physician. It is important to get to the hospital as soon as possible. Do not attempt to drive yourself; a loss of consciousness on the road can be deadly for you and others. With prompt and proper treatment your survival rate greatly improves.
