February is the American Heart Association’s “Go Red” month – their annual campaign to educate Americans about the #1 killer of women. Today, Friday February 5th, is Go Red For Women day — an opportunity to wear a fiery red lipstick, a festive red blouse or your high, red heels.

While donning your crimson clothes, it’s important to also be aware of heart disease — which kills more women each year than breast cancer. Nearly 1 in 3 women will die from cardiovascular disease and 90 percent of women have one or more risk factors for developing heart disease in the future.

38-year old actress Jennie Garth has joined the campaign to help spread the word. “After learning of my own heart condition and losing my father to heart disease, I know how important it is to speak up about this silent killer,” she said. “Too many women remain unaware.”

So, what are the risk factors?

Diabetes is one of the most significant risk factors for heart disease: diabetes increases the risk of heart disease three to seven times in women. Low levels of HDL (high-density lipoprotein), the “good” cholesterol, also have shown to be a stronger predictor of heart disease deaths in women. High levels of triglycerides, another type of fat, also appear to be a particularly important risk factor in women.

And, it’s important to know that the symptoms of heart disease and heart attack in women are different from men. For a list of some symptoms, click here.

So put on a sexy red outfit and make sure you take care of yourself!
