Women have almost half of all heart attacks in the U.S., reports the National Heart, Lung and Blood Institute. Heart disease is the No. 1 cause of death for women. Women often know they are not feeling right in the time prior to a heart attack. However, women often delay getting medical care. Cardiac disease causes more than 40 percent of female deaths in the U.S.; one in four women older than age 65 has some form of heart disease, notes the Texas Heart Institute.
Atypical Fatigue
Unusual fatigue is the most common symptom of a heart attack in women, reports the National Institutes of Health (NIH). About 70 percent of women who have had a heart attack report surprising levels of fatigue in the time prior to the heart attack. When unusual fatigue arises during daily activities, it is important to seek medical care.
Shortness of Breath
Another key warning sign of a heart attack in women is the occurrence of shortness of breath. About 42 percent of women experience this symptom prior to a heart attack, says the NIH. When this symptom occurs, especially if it appears without exertion, you should go to an emergency room or contact your doctor.
Sleeping Difficulties
Problems with sleeping through the night are often also a sign of an impending heart attack in women. The NIH says that about 47 percent of women have this symptom before a heart attack. Any irregularity with sleep patterns is important and should be discussed with a doctor.
Anxiety
A feeling of anxiety for unknown reasons is common for women in the days and weeks leading up to a heart attack. About 35 percent of women experience this symptom before a heart attack, according to the NIH.
Cold Sweat & Nausea
If you find yourself experiencing a sudden episode of a cold sweet and possibly also feeling nauseated you may be having a heart attack. These serious symptoms warrant immediate medical attention.
Indigestion
Another symptom you may experience before a heart attack is indigestion. If this problem strikes get it checked out; it often indicates a heart problem.
Dizziness
Feeling dizzy is also a symptom of a heart attack in women. If you suddenly feel disoriented due to a bout of dizziness seek immediate medical attention.
Chest Pain
Chest pain is also a sign of a heart attack in women. This symptom, however, is seen in only less than 30 percent of women, says the NIH. The pain may range from mild discomfort to severe pain. Do not delay when you feel this symptom; seek medical help at once.
Pain in Upper Body
Pain in other areas of the upper body will offer more clues that a heart attack is imminent. If you feel pain in the upper arms, neck, jaw, back, or stomach it is crucial to seek medical care.
