“It’s a man’s disease.” “But I’m too young.” “Breast cancer is the real threat.” If you’ve heard or said any of this before, you’re not alone.

The real fact is, relying on these false assumptions can cost you your life. And for 19-year-old Regan Judd, it nearly did. “I kept thinking of my grandpa. But he was so much older than me that I just couldn’t grasp it.”

Who could blame her? The last thing a young, energetic college athlete has on her mind is contemplating open-heart surgery. But, a combination of family history and a heart murmur since birth meant a diagnosis of heart disease, despite her youth and active lifestyle.

It’s time to set the record straight and start thinking of this as a disease that doesn’t spare woman and children. Your health is non-negotiable; we need to separate fact from fiction so that together, we can stop this killer once and for all.

Myth: Heart disease is for men, and cancer is the real threat for women

Fact: Heart disease is a killer that strikes more women than men, and is more deadly than all forms of cancer combined. While one in 31 American women dies from breast cancer each year, heart disease claims the lives of one in three. That’s roughly one death each minute.

Myth: Heart disease is for old people

Fact: Heart disease affects women of all ages.  For younger women, the combination of birth control pills and smoking boosts heart disease risks by 20 percent. And while the risks do increase with age, things like overeating and a sedentary lifestyle can cause plaque to accumulate and lead to clogged arteries later in life. But even if you lead a completely healthy lifestyle, being born with an underlying heart condition can be a risk factor.

Myth: Heart disease doesn’t affect women who are fit

Fact: Even if you’re a yoga-loving, marathon-running workout fiend, your risk for heart disease isn’t completely eliminated. Factors like cholesterol, eating habits and smoking can counterbalance your other healthy habits. You can be thin and have high cholesterol. The American Heart Association recommends you start getting your cholesterol checked at age 20, or earlier, if your family has a history of heart disease. And while you’re at it, be sure to keep an eye on your blood pressure at your next check-up.

Myth: I don’t have any symptoms

Fact: Sixty-four percent of women who die suddenly of coronary heart disease had no previous symptoms. Because these symptoms vary greatly between men and women, they’re often misunderstood. Media has conditioned us to believe that the telltale sign of a heart attack is extreme chest pain. But in reality, women are somewhat more likely to experience shortness of breath, nausea/vomiting and back or jaw pain. Other symptoms women should look out for are dizziness, lightheadedness or fainting, pain in the lower chest or upper abdomen and extreme fatigue.

Myth: Heart disease runs in my family, so there’s nothing I can do about it

Fact: Although women with a family history of heart disease are at higher risk, there’s plenty you can do to dramatically reduce it. Simply create an action plan to keep your heart healthy.

Because of healthy choices and knowing the signs, more than 627,000 of women have been saved from heart disease, and 330 fewer are dying per day. What’s stopping you from taking action?
