As an awareness issue, here are the signs of a heart attack for women:
What are the common symptoms of a heart attack?
The most common symptoms of a heart attack are:
Chest pain
Shortness of breath
Sweating
Pain in one or both arms
Chest pain is the most common symptom of a heart attack. Women often describe their chest pain as pressure, tightness, or an ache. But many women do not experience severe pain during a heart attack; for this reason, women should also take milder chest pain seriously. When chest pain occurs, it usually feels like discomfort in the center of the chest that lasts for more than a few minutes; this pain may come and go.
Many heart attack patients do not feel any chest pain. This is especially true for women. In the study of 515 women who suffered heart attacks, 43% did not experience any type of chest pain or pressure during their heart attack.1 About one third of the women in the study did feel chest pain, but most did not describe the sensation as “pain,” instead describing the feeling as “pressure,” “aching,” or “tightness.” Although you may not consider what you are feeling to be pain, chest sensations may indicate heart disease or a heart attack.
Shortness of breath may occur at the same time as the chest pain or it may occur before it. Shortness of breath has been found to be more common in women, whereas sweating is more common in men.
What are some "atypical" symptoms?
"Atypical" symptoms are symptoms other than the ones mentioned above; however, the term "atypical" is misleading because these symptoms are actually relatively common. “Atypical” symptoms include (but are not limited to):
Back, neck, or jaw pain
Nausea
Vomiting
Indigestion
Weakness
Fatigue
Dizziness
Lightheadedness
Women experience more "atypical" symptoms at the time of a heart attack than men. In one study, women were more than twice as likely as men to experience nausea, vomiting, or indigestion as heart attack symptoms.
What are pre-heart attack symptoms?
Pre-heart attack or prodromal symptoms are symptoms that occur before a heart attack, generally from about 4 to 6 months to 1 week before (though some people report these symptoms up to 2 years before their heart attack).
Common pre-heart attack symptoms include:
Unusual fatigue
Sleep disturbance
Shortness of breath
Chest pain
Indigestion
Anxiety
Pain in shoulder blade or upper back
Shortness of breath seems to be a particularly important symptom for men and women, though it is often not thought of as a serious medical concern. In a study of nearly 18,000 men and women (40% were women), those who experienced shortness of breath were 3 to 5 times more likely to die from heart disease than those who did not have this symptom. This symptom seemed to be a particularly good indicator of heart troubles for people who were not previously aware that they had heart disease.
