The NHLBI logo can only be used with permission by the Institute. The NHLBI logo is designed to signify official NHLBI products, activities, events, representatives, and facilities. It should never be used to promote or suggest endorsement of non-NHLBI products, events, or services.

The NHLBI logo consists of a graphic mark that includes the acronym "NIH" and the name of the Institute (spelled out).
