The first Friday of February has been designated by the awareness campaign, Heart Truth, as National Wear Red Day in the United States. On this day, men and women are encouraged to wear red as a symbol of their support of women’s heart health. According to the National Heart, Lung and Blood Institute (N.I.H.) in the U.S, Coronary Heart Disease is the “#1 killer of women in the United States”. The day, which was first observed in 2002, aims to bring national attention to this fact, and to raise awareness of women’s heart health. Today we picked books on prevention and screening of heart disease.
