Wear Red: How to manage your heart disease risk factors Today is Go Red For Women day, part of a month-long national campaign to raise awareness for women's heart health. Heart disease is the leading cause of death for American women, killing about 300,000 each year. But a new survey shows that fewer than half of women are aware of the danger. CBS News medical contributor Dr. Tara Narula, cardiologist at Northwell Health, joins "CBS This Morning" to discuss raising awareness and prevention.
