THE BRONX - Red was the clothing color of choice for millions of women nationwide Friday.

The American Heart Association aimed to spread awareness about heart disease through National Wear Red Day with Go Red For Women as part of February's American Heart Month.

The cardiovascular disease is the top killer of women in the United States, affecting an estimated 43 million each year.

Some of the symptoms include dull, heavy or sharp chest pain, pain in the neck or jaw, and pain in the upper abdomen or back.

Besides knowing the warning signs, doctors say women with a family history of heart disease should get regular check-ups and blood pressure screenings, and stay active.

Hospital employees at Montefiore Medical Center will be wearing shirts to help spread the word about heart disease. Free public events like exercise classes, health screenings and food demonstrations will also be held at various Montefiore campuses throughout the month.
