Heart attack symptoms that are unique to women include subtle chest pressure; discomfort in the abdomen, neck, shoulder or upper back; and right arm pain, according to Mayo Clinic. Other symptoms include sweating, lightheadness and unusual fatigue. Women often experience the symptoms when at rest, asleep or under mental stress.
Women tend to delay seeking emergency treatment because they do not relate their symptoms to traditional heart attack symptoms. For example, women's chest pain symptoms may feel more like tightness, notes Mayo Clinic. This is due to a condition many women have, called small vessel heart disease or microvascular disease. The disease causes blockages in the smaller arteries that supply blood to the heart, combined with blockage of the main arteries.
