With the Heart Health stamp, the U.S. Postal Service hopes to raise public awareness about the importance of maintaining a healthy heart. The design shows a bright yellow sun disc, a leafy green tree icon, and a blue swirl of a sky. The striding figure at the center of the stamp has a full red heart. At the figure’s feet, a large red apple represents a well-balanced diet, another essential factor in maintaining a healthy heart.

Although CHD is the leading cause of death among women and men in the U.S., it doesn’t have to be. Many cases of heart disease can be prevented. Most people can lower their risk of developing CHD –and protect their hearts for a lifetime –  by making just a few lifestyle changes. Exercising and eating a heart-healthy diet are critical factors. Quitting smoking, managing stress, and getting enough sleep are equally important.

Because heart disease can develop over decades without symptoms, many people do not know they have it. Some risk factors, like age and a family history of CHD, can’t be avoided, but regular medical checkups make early detection and treatment possible.
