(KCEN) -- Today is not only national Wear Red Day but it's also the 10th anniversary of the Go Red for Women national heart campaign.
That's because today marks a decade since the campaign was initiated.
Over the past ten years, awareness has gone up and deaths from the disease have gone down.
According to health officials, heart disease is still the number one killer of women.
But the American Heart Association and the Go Red for Women organization see today as the start of a year-long effort to help women make small changes that could change that.
For some women, discovering they have heart disease changes their life forever.
Heart disease patient Mary Leah Coco said, "It was pretty world-shattering and life-altering to find my heart was functioning at 10% of what it should be."
According to campaign officials, 90 percent of people who registered with the Go Red Campaign made a healthy lifestyle change, like changing their eating or exercise habits or getting their cholesterol checked.
