Unlike in men, pain, pressure, or discomfort in the chest are not always severe or even the most prominent heart attack symptom in women. That’s why women need to understand their unique symptoms while also working to reduce their risk of heart disease, revealed researchers at the Mayo Clinic. Sweating, nausea, dizziness, and unusual fatigue may not sound like typical heart attack symptoms, but are common in women, and may occur more often when resting or asleep, according to the study. When women experience symptoms of a heart attack, those signs often are misinterpreted. Women’s symptoms often are vague — shortness of breath, nausea/vomiting, and back or jaw pain. Other women experience dizziness, lightheadedness, pain in the lower chest or upper abdomen, and extreme fatigue.
