Cardiovascular disease is the number one killer of women. One in two women will die from heart disease or stroke. Compare that to one in 25 who will die from breast cancer (no, I didn't make this up - see Agency for Healthcare Research and Quality).
Heart disease includes high blood pressure, diabetes, coronary artery disease (which causes heart attack), congestive heart failure, and various types of heart rhythm and function issues. According to the Cleveland Clinic, 8 million women in the U.S. are living with some form of heart disease.
If you're a woman and you experience unexplained chest pain or shortness of breath - see your doctor! Know the symptoms and your risk factors - see the American Heart Association for more information.
