Symptoms of heart attack in women are different than they are in men. In fact, 43 percent of women having one don't feel any chest pain at all. What do they experience? Extreme fatigue. "In the days or even weeks before a heart attack, more than 70 percent of women experience debilitating, flu-like exhaustion," says Marianne Legato, MD, director of the Foundation for Gender-Specific Medicine in NY. "You may suddenly feel too tired to cook dinner or lift your laptop."
Other signs to watch out for: mild pain in the breastbone, upper back, shoulders, neck, or jaw, as well as profuse sweating, nausea, dizziness, breathlessness, sleeplessness, and anxiety. If you do experience any—or all—of these signs, call 911. Your odds of surviving a heart attack improve by 23 percent if you get treatment within three hours, and 50 percent if it's within one hour.
